Which insulation is better isover or rockwool. Glass wool thermal insulation materials - an overview of the best brands of insulation

Keepers of warmth and silence

One of the most important criteria for the quality of mineral wool is its environmental safety. defining safety factors material, the following points are considered:

• Length and diameter of mineral fibers;
• The quality and chemical composition of the binder;
• The presence of environmental certificates from the manufacturer.

The best manufacturers of mineral wool

Only brands with a proven track record deserve consumer trust. Among them, it is worth paying attention to the brands:

• rockwool
• Paroc
• Isover
• Knauf
• IZOVOL
• Beltep

7 leaders of narrow and broad specialization are fighting for buyers by advertising their product. In contrast to this, ExpertTsen will try to give an unbiased assessment of the heat-insulating material and rank the types of mineral wool based on their safety, building merits, taking into account the average price tag and feedback from real buyers.

Rockwool - stone wool without flaws

Despite its Danish roots, Rockwool has many factories in Russia, which allows the company to offer a range of European quality, but without extra price markup. The high quality of this mineral wool is confirmed by the builders, consistently choosing the products of the Danish brand during the work.

Rockwool mineral wool is enhanced performance:

• fire safety - Rockwool fibers can withstand up to 1000 degrees with standard data of 600 degrees Celsius;
• absorption of sound and vibrations, so the material is chosen to create noise barriers and to increase the acoustic comfort of the premises;
• environmental friendliness - Rockwool has an EcoMaterial Green certificate, although it has long been known that many dislike mineral wool, attributing to it properties that are dangerous to the environment, human life and health;
• durability without deformation and destruction;
• thermal insulation.

We are talking, of course, about the real Rockwool, buying from unreliable suppliers does not guarantee the above quality.

Reviews: "Rockwool light butts mineral wool is the best - perfectly holds the dimensions and does not crumble."

“The house was saved from a fire only due to the presence of Rockwool slabs in the ceiling - it does not burn, does not shrink, does not form dangerous voids at high temperatures.”

Mineral wool Paroc - excellent quality, but high price

Having opened any construction forum, in the topic "thermal insulation" you immediately come across the name of the Parok brand. His basalt mineral wool is firmly in the lead in the user rating, and there are many reasons for this. After all, Paroc is about the same quality of products, regardless of the location of the plant, and the best characteristics for all the main indicators of mineral wool.

Paroc focuses on energy efficiency. Basalt wool Parok allows you to:

• save energy, including heat;
• not have a negative impact on the environment;
• protect from noise and dust;
• ensure fire safety.

This manufacturer has implemented all the advantages of stone wool, there are practically no fakes, but flaw still present - high price.

Reviews: “Paroc mineral wool is my favorite! I plan to use it on the roof of my house.”

Isover - high quality mineral wool to choose from

The manufacturer offers two solutions: glass wool and stone wool. This is a big plus when choosing thermal insulation, since both of these materials are usually in demand in the construction of an object. Isover has an excellent reputation in Russia and offers thermal insulation only with environmental quality certificates. The constant introduction of modern technologies allows us to improve the characteristics of our products and at the same time reduce the cost. The latest "novelty" from Isover is the release of mineral wool with high strength and elasticity, without dust and with a minimum of "pricklyness". In terms of quality, products under this brand are unlikely to compare with more expensive competitors, but in terms of price / quality ratio, Isover mineral wool is one of the best.

Reviews of builders: "Mineral wool Izover is cheaper and better than many other heaters, so I use it for a large volume."

Knauf - makes everything!

Knauf is a manufacturer that has proven time and again that it can provide the construction market with the best deals. Thermal insulation is no exception. Knauf offers good quality mineral wool based on basalt fiber as well as glass fiber composition. The first option is widely used for technical insulation, in construction and in the production of complex equipment. Fiberglass insulation is produced for specialized purposes ( HEATKnauf), which is confirmed by its names:

• HEATWALL;
• HEAT stove;
• HEAT-roofing;
• Acoustic partition;
• THERMAL roll.

Most of the mineral wool sold by the manufacturer belongs to the series Knauf Insulation. There are no poisonous phenol-formaldehyde resins in the production of this product. The Knauf Insulation and TEPLOKnauf thermal insulation lines are designed for the construction of residential buildings by individuals and construction organizations.

Flaw: high price

Reviews: “You rarely hear a bad word about Knauf. So the material is really excellent.”

Ursa - a new generation of mineral wool

For a long time, the Ursa brand has been known for its fiberglass products. But technology does not stand still, and today the company offers the market PureOne- mineral wool of a new generation from natural and renewable components, interconnected by an acrylic-containing binder.

The efficiency of PureOne in terms of heat and sound insulation is very high, there are almost no complaints about other characteristics. The material has a bright white color, does not prick, does not crumble, does not deform.

In addition to PureOne, Ursa also offers a standard range of glass wool, with all their advantages and disadvantages. The cost of products does not differ from analogues of other companies.

Reviews of builders: "PureOne is the best mineral wool, 1.5 times more resilient and stiff than traditional fiberglass heat insulators."

“A friend who has been working on the construction of summer cottages for more than one year said: take Ursa insulation, you won’t regret it - it keeps you warm, and it’s easy to work with it, and it doesn’t burn. .

IZOVOL mineral wool is the best choice for walls and roofs

Izovol is another type of basalt wool that is in high demand and is used for thermal insulation of walls, roofs and ventilated facades. It has excellent physical, mechanical and operational characteristics. Non-combustible, has standard density indicators for the material, therefore it can crumble during operation, causing some discomfort.

It does not have a high price, all thermal insulation is available for sale and is in demand by construction organizations. The most popular line of materials recommended for work on the insulation of pitched roofs and attic spaces.

Thermal conductivity is an important characteristic of building materials. The modern consumer prefers a product with the best performance characteristics, namely, a popular brand.

It is difficult to find a good manufacturer, especially when there are so many products from various companies on the domestic market that it is difficult to understand where the product is of high quality and where it is not.

The main characteristics of mineral wool, which you should pay attention to when choosing:

1. Thermal conductivity.
2. Cotton density.
3. Water repellent properties.
4. Protection against chemical influences.
5. The thickness of the building material

Cost is the first thing buyers pay attention to when choosing a heater, but you should know that the price of different suppliers will be very different, as some offer installation work and their delivery right away.

When choosing a good insulation, you should focus on the list of material properties. The more features, the better. By comparing the possibilities and cost of building materials, you can choose the best option for yourself.

The undisputed leaders in the manufacture of thermal insulation are the following companies:

1. Rockwool. Mineral wool produced by the company is actively used in many areas. Mineral wool of the brand is made exclusively from basalt.
2. Izover. Leading manufacturer of thermal insulation.
3. The company produces thermal insulation using a special environmentally friendly technology.
4. It is engaged in the production and sale of various building materials, including those related to thermal insulation.
5. TechnoNIKOL. Manufacturer of quality insulation.

Among the leading companies, it is worth noting two, which will be discussed further. Which is better: Ursa or Knauf, whose products can better cope with the thermal insulation of rooms. Thermal conductivity is one of the most important characteristics for any insulation, therefore, the lower it is, the smaller the layer applied to walls, floors, roofs and other structures.

Products of the Knauf brand are distinguished by sufficiently high performance and environmental friendliness. Their product is completely harmless to others. Unlike similar heaters, the Knauf brand does not use phenol-formaldehyde resins, since they contain many different harmful substances.

The most significant operational properties:

1. Well isolates the room from extraneous noise.
2. Mold and other formations do not form on the material.
3. Fireproof. When a fire occurs, the mineral wool will resist the further spread of fire.

URSA manufactures thermal insulation materials that effectively insulate walls, floors and roofs, as well as ventilation ducts and other utility networks. Such thermal insulation absorbs noise well and with a long service life. In various fields (industrial and private), the excellent characteristics of the mineral wool manufacturer URSA determined the popularity of the product.

Ursa fiberglass is characterized by elastic and durable fibers. Between them there are layers ignited by air, which retain heat more efficiently. In addition to the distinctive indicators of insulation, mineral wool is able to completely isolate the room from extraneous sounds. Rating 9.9 points out of 10.

The topic of modern heat-insulating materials, both imported and domestic, continues to interest readers, because thanks to these materials, one can not only reduce the cost of heating housing, but also significantly reduce the cost of building construction. Leading specialist advises.

What are the advantages of URSA and Izover heat insulators?

I had to work with Russian mineral wool. Despite a special protective suit, a respirator, particles of the material fell on the body and lungs, causing very unpleasant sensations. People who constantly work with her, often received dangerous occupational diseases. Another drawback is that this heat insulator quickly collapses in the wall, sags, as a result of which the upper part of the wall loses thermal insulation, while in the lower part it deteriorates significantly. The thermal insulation materials that we offer are completely environmentally friendly and even pleasant to the touch, durable, have the best insulating properties and, finally, are cheaper than those made in Kstovo or Vyksa.

- Is there any difference between URSA and Izover?

If it is, it is highly conditional. Both materials are fiberglass, both have the same technical characteristics, even their appearance is so similar that not every specialist will be able to distinguish them when unpacked. By the way, their packaging is the same - a shrink film, which reduces the transport volume by up to 35 percent of the working volume, which makes it possible to place three cubic meter packages of this heat insulator into ordinary Zhiguli.

But "Isover" we bring from Finland, and "URSA" is made in the city of Chudovo, Novgorod region. Many consumers prefer imported material (it is a bit more expensive), although the Germans, the owners of the Chudovsky plant, strictly ensure that the material produced here does not differ in any way from that produced in their homeland or at the concern's factories in other countries of the world. Another question is that the capacities of the Chudovka plant are not enough for the whole of Russia and very often people are simply forced to use imports ... - Where are these heat-insulating materials used and what are their varieties? - Between themselves, they differ in rigidity - from M-15 to P-75 (the harder the material, the higher the wall it can be laid, but the more expensive it is), in thickness - from 50 to 140 mm. On one or both sides of the material, polyethylene film, foil or kraft paper can be applied. Since they are classified as non-combustible and have excellent thermal insulation properties (their thermal conductivity coefficient is only 0.04-0.05 kcal / mchC, which means that 18 cm of heat insulator protect the house from the cold in the same way as two-meter brickwork), environmentally friendly, they can be used for thermal insulation of roofs, interfloor ceilings, and external walls, and floors, and basements, and internal partitions, and heat pipes. In short, they are universal. At the same time, such materials are very convenient to use. Install an interior partition - place between a wooden beam or a metal profile on which drywall or GWP is attached, an insulating plate of medium hardness with a thickness of only 50 millimeters. Such a partition will provide better heat and sound insulation than one laid out in one and a half bricks. But it does not need to be plastered. The labor costs for its construction are incomparably less. Due to its low weight, it can be placed almost anywhere, besides, the cost of the materials themselves is lower...

This is probably the main advantage of modern thermal insulation materials:

providing better quality at lower cost. For example, when building a protective wall, you can make it out of brick. And it is possible to build from it only the inner, load-bearing part of the wall with a thickness of only 175 mm (half-brick), attach an 80-120 mm layer of heat insulator to it and lay it with any facade material (besser blocks, facing bricks, siding, boards). The price will be much cheaper, but the comfort of housing, its heat protection is better. And there is no need to be afraid of these building structures - this is how they build in many countries of the world, where they live much better than in Russia. I had to meet and more economical solutions. A wooden beam is used as the supporting part of the structure, between which a heat insulator is attached, the inner part of the wall is sheathed with a GVP, and the outer part is lined with grooves. Outwardly, such houses resemble garden houses, but they are warm and comfortable.

You spoke about the advantages of URSA and Izover materials, but did not mention anything about their shortcomings.

Disadvantages? Perhaps only one. They don't like moisture. When hit, it partially loses its properties. Therefore, they cannot be wetted, and condensate should not accumulate on them inside the building structures. For this, special ventilated structures have been developed or polyethylene film, aluminum foil or kraft paper are used as vapor barriers.

At the end of March, the Independent Press Center in Moscow hosted a round table on the safety of building materials. A new construction season begins, which can bring people not only the joy of a housewarming party, but also the bitterness of serious illnesses. Unfortunately, this is not an exaggeration. “Recently, a large number of people, whose homes have been overhauled, have begun to turn to hospitals with symptoms of allergies, bronchial asthma or bronchitis,” said one of the event participants Dmitry Vinogradov, Candidate of Medical Sciences, Associate Professor, pulmonologist of the 1st Moscow State Medical University named after . THEM. Sechenov. All participants of the round table agreed that one of the main causes of respiratory diseases is the "respirable" dust caused by asbestos and mineral wool.

Fortunately, asbestos is not commonly used in construction and renovation today. But mineral wool is everywhere. Mineral wool is used for insulation of walls, floors, ceilings, roofs, loggias, attics, as well as sound insulation. Mineral wool is available in foil, in the form of sandwich panels, cords, cylinders or mats, and is sold in the form of rolls and plates.

Installation and fastening of mineral wool (including with the help of glue) is carried out both inside and outside the premises. In Russia, there are quite a few plants that have established the production of mineral wool, in particular, a similar enterprise operates in the city of Zheleznodorozhny, Moscow Region.

You can buy mineral wool at any hardware store. The price of mineral wool depends on weight, density, composition, thermal conductivity. Naturally, the brand of the manufacturer also affects the cost of mineral wool, the most common of which are rockwool (rockwool), ursa (ursa), isover (izover), knauf (knauf), technonikol (technonikol).

Which minvata is better? The participants of the round table unanimously declared: none. Unfortunately, today few people know that mineral wool is a very dangerous, poisonous and insidious insulation. Sergey Fateev (building portal SNRP.RU) said that the smallest particles of mineral wool fibers inhaled by a person cause serious harm to the body - up to cancer. Moreover, the phenol-formaldehyde resins used in this insulation as a binder are of great danger. These substances release free phenol and formaldehyde, which can provoke inflammation of the skin, mucous membranes, and even nervous disorders.

“In Western countries, much more harmless substances are used in the production of mineral wool, for example, limestone, while in Russia, slags from the metallurgical industry are used to save money,” said Sergey Fateev. And representatives of the environmental organization "Green Wave" said that they intend to study modern brands of mineral wool for their safety for people and the environment, and demand that officials impose a ban on harmful materials.

According to some participants of the round table, the widespread use of mineral wool is very similar to the story of the so-called "phenolic" houses. In the late 1960s - early 70s, high-rise buildings began to be built throughout our country, adding phenol-formaldehyde resins (now used in mineral wool) to concrete.

A huge scandal erupted in the late 80s, when it became known how poisonous these residential buildings had become.

The inhabitants of these houses got chronic diseases of the respiratory tract, cardiovascular and digestive systems, liver, kidneys, eyes. Among the residents of "phenolic" houses, statistics reveal an increased number of deaths from cancer.

Is history repeating itself? Quite possible, say the participants. Mineral wool today is installed in many residential and office buildings, including private buildings. Toxic dust that exudes phenols and formaldehydes, plus rodents, who are so fond of such an environment, are carriers of infection - all these factors cannot but affect people's health. Chemical components in the air are absorbed and accumulated in the human body, leading to a decrease in efficiency, fatigue, a decrease in concentration, and with prolonged exposure - to malignant neoplasms.

The construction season is just beginning, so people who order construction or repair work need to make sure that their housing and work premises meet all environmental standards in advance. But if fate has settled a person in a building whose walls, floors or ceilings are insulated with mineral wool, then it is necessary to ventilate the room more often and carry out wet cleaning, the participants of the round table are sure. This way you can reduce the impact of toxic dust and reduce the concentration of chemical components in the air.

Visitor comments

Alexander (guest)

Mineral wool or fiberglass heaters are very harmful. Firstly, the fibers from which these heaters are made are very fragile. Therefore, even with a slight load, they break.

isover or knauf

Secondly, the fibers of these heaters are interconnected by glue or resin (phenol is released) and under the influence of the natural environment (temperature changes), the fiberglass or basalt insulation is destroyed, that is, the fibers fall off, and this, as a result, leads to the formation dust harmful to the human body.

Environmentally friendly insulation (the entire line: linen, jute, organic), you can see here: domorus.ru

ORIENT211 (guest)

1) Mineral wool mats made of basalt fiber used as insulation do not contain binding components. Therefore, no chemicals are emitted. And they can serve as a source of health hazard only because of the dust. However, this mineral dust is not always able to penetrate into the air of the room.
2) Mineral wool boards are not only on a synthetic binder that releases phenol, but also on starch or bitumen.
3) The video shows that the rats are dying, but not the fact that because of the mineral wool. In addition, it is not clear why there are so many rats in this house. They don't eat mineral wool, so they found something edible with their owners. This means that the owners did not take good care of their products.

Comparison of roofing insulation "Knauf Cottage" and "Ecover"

Knauf and Ecover are well-known brands of roofing insulation among Russian builders. Since we ourselves use these heaters, we boldly recommend them to our customers. In this article we will tell you how the products of these brands differ.

Glass wool and basalt wool

Similarities

The main characteristic of heaters - thermal conductivity - both types are almost the same. So with any properly laid insulation in the house there will be a comfortable temperature.

Insulation plates from both materials are cut with a knife.

Although both mineral components are environmentally friendly, when working with heaters use a mask and gloves. Breathing dust that flies from the stoves is harmful to the lungs.

Differences

The main difference between heaters is in materials. “Knauf” is glass wool, and “Ecover” is stone, or basalt, wool.

Glass wool is made from broken glass and sand. The raw material is melted in the furnace, turns into thin fibers, which then form the plate.

Basalt wool is made from a natural fossil - gabbro-basalt rocks. For Ecover, raw materials are mined in the Urals, in the city of Asbest. Stone is also melted in a furnace.

What's better? Izover Rockwool Ursa Teplo knauf

The fibers are bound with phenol-formaldehyde resins - despite the terrible name, they are safe.

Advantages of basalt wool "Ecover":

• Mineral fibers are randomly located in basalt slabs, so stone wool is stronger than glass wool.
• Insulation "Ecover" requires moisture protection, but when wet it does not lose its thermal insulation properties.
• Basalt wool is tough, so it does not collapse under its own weight and light loads, and does not shrink over time. 50 years of service without complaints.
• Basalt wool has a higher melting point: 600-700 degrees versus 450 for glass wool. Therefore, stone wool is more resistant to high temperatures - for example, in a bathhouse, and is not flammable.
• Basalt wool is used under plaster, under screeds - it does not deform.

Cons of Ecover

• Basalt wool takes up a lot of space during transportation, which is partly why it costs more.
• During installation, the plates almost do not crumple, so the fibers crumble, dust is formed.

Advantages of glass wool "Knauf"

• Glass wool is flexible and soft, so it is easy to transport and place on uneven surfaces.
• Glass wool isolates the room better from street noise.
• Glass wool is lighter than basalt wool, therefore it loads the structure and the hands of the builder less.
• For the production of glass wool, an acrylic binding agent is used, which is more environmentally friendly than phenol-formaldehyde.

Cons "Knauf"

• Since this insulation is made of glass, it pricks a little during operation. Be sure to follow safety precautions - work only with gloves!
• The fibers of glass wool are parallel to each other, so glass wool is not as strong and shrinks a bit over time.

Conclusion

Basalt wool is more expensive than glass wool, so first of all start from the budget. Basalt wool lasts longer and does not shrink, and glass wool does not load the frame and is laid on uneven surfaces.

We hope this comparison has helped you make an informed decision and buy the best roofing insulation for your application.

1. Roof insulation - how to choose?

2. Manufacturer Rockwool

3. Manufacturer Knauf

If you want to create a rest room in the attic or decide to update the material, then be sure to ask yourself the question - what kind of insulation is best for the roof? (read also: "Choosing roof insulation - which one is better and more practical")

In our article we will talk about the choice of such material. After all, manufacturers offer a fairly large range of goods, different in type and variety. And in order to make the right choice, it is necessary to take into account all the nuances, for example, the density of the insulation for the roof.

The roof has long been synonymous with warmth, reliability and comfort at home.

For this reason, you should be very careful when choosing a roofing insulation.

A reasonable question arises - why insulate the roof, because you can do without it? But no! After all, as you know, warm air always goes up.

And if the roof itself is cold, uninsulated, then the air flows will go into the atmosphere. If the roof is properly maintained, warm air will linger in the room. For this reason, if you do not properly insulate your roof, you will spend significantly more money on gas or electricity to heat your home. Today, such expenses really look redundant.

Attic roofs are of two types:

Consider the difference in their insulation.

Residential attic spaces require insulation not only of the roof slopes, but also of part of the ceiling, and even side walls.

Non-residential - insulation of floors separating the attic and the house. In this case, the thickness of the insulation for the roof will be different.

Roof insulation - how to choose?

Before buying a heater, read the information about the materials used and the manufacturer. Examine the characteristics of the heat insulator you have chosen. But the most important thing is to calculate the insulation for the roof. This is important in order not to buy too much.

Consideration of principles when choosing a heater

The only thing I want to note is the choice of material, depending on the type of roof (flat or pitched). The rest of the criteria are the same for everyone.

So, eight criteria:

1. Life time. If the insulation is of high quality, then it retains its thermal insulation properties for a long time.
2. Specific gravity. It is affected by the density of the insulation, which is measured in kg / m3. The material should not be too heavy, otherwise it will lead to the weight of the entire structure. And this threatens with dangerous consequences.
3. Form stability. When buying material, pay attention to the technical specifications. Especially at the point of the duration of the preservation of its geometric parameters by the heater. In other words, it defines reliability.
4. Flammability. It is recommended to give preference to non-flammable and self-extinguishing materials.
5. Cold resistance. Actual criterion, especially for the regions of the north.
6. Humidity. There are materials in which thermal conductivity deteriorates with increasing humidity - this is not a plus.
7. Soundproofing. If the roof covering is made using noisy material, then the insulation must necessarily have soundproofing properties.
8. Environmental friendliness. The insulation must not smell or be toxic.

Installation of rockwool insulation, see the video:

So, let's move on to the types of heaters themselves.

Types of insulation for the roof:

• foamed polystyrene foam - belongs to the class of foam plastics, consists of gases that fill the material. As a rule, it is applied to warming of flat roofs. The service life is about 50 years. Significantly more effective than mineral wool because it is light in weight.
• polyurethane foam - used for insulation work on the roof or attic. Belong to the group of gas-filled plastics. It has low thermal conductivity and is light in weight. The material is not subject to moisture and vapors, and also has a long service life.
• stone wool , whose slabs consist of mineral wool. The material perfectly saves heat and is not exposed to fire. Stone wool has low moisture absorption, as well as resistance to rodents and microorganisms.
• glass wool - made from waste glass production and boasts good thermal insulation characteristics.

Stone slabs are the most popular. After all, they are suitable for warming both pitched and flat roofs. If we talk about manufacturers, I would like to note: Rockwool and Knauf.

Manufacturer Rockwool

Danish roofing insulation rockwool occupies a leading position in the Russian sales market. Today there are three directions of the company, but we will focus only on insulation for a flat roof.

Rockwool - roofing insulation

It is a mineral wool slab of basalt rock. The area of ​​application is multilayer structures. The task is thermal insulation of flat roofs.

It is also possible to use roof screed material without cement. However, not all products of this brand are able to effectively insulate the roof. After all, the range is represented by universal and special plates.

For example:

• Rockwool Roof Butts designates the bottom layer with the letter H, the top layer with the letter B, and the universal one does not have a letter designation.
• Rockwool Cut-to-falls Roof Slab and Rockwool Underlay Roof Slab are used as the bottom layer in a sandwich construction.

  Advice : Where there is no required roof pitch, Cut-to-falls Roof Slab is usually used.

• Rockwool TF-Board is used in single layer constructions or as a top layer. You can use the material as a condensate insulation in corrugated roofs.
• Hardrock 50/100/120/180 - plates have different thicknesses. They are used for both single layer roofs and top ball. The advantages include moisture-proof and water-repellent properties.

All products of the aforementioned company have good characteristics and a long service life. They are easy to use during installation due to zero coefficients of linear expansion and shrinkage.

Manufacturer Knauf

Thermal insulation products of the Knauf company are very popular all over the world. Enterprises are located in hundreds of countries in Europe, Asia and North America. The company's products are suitable for pitched roofs, walls, floors and facades of buildings.

Insulating material - glass wool, which has increased elasticity and contributes to a snug fit of the insulation to the wall.

The material freely passes steam through itself, however, this does not violate the optimal climatic conditions in the room.

Basalt wool is a material made from fibers of metallurgical slags and silicate melts.

The positive properties of the insulation: good sound and thermal insulation, as well as fire resistance.

The material is sold in the form of rolls and plates. All products are famous for their quality, long service life, ease of installation, as well as environmental friendliness in use.

We repeat that when choosing a technonicol roof insulation, pay attention to thermal insulation. It should be suitable for your particular type of roof.

Be sure to consider all factors, such as: type of roof, region of residence, insulation material for the roof, etc. At the same time, one should not forget that a wide range of measures should be carried out, in particular, the calculation of the thickness of the roof insulation.
