Thermal insulation ISOVER Sauna series. Insulation of saunas and baths with ISOVER Isover products: Is the density of thermal insulation materials important?

ISOVER Sauna insulation is fiberglass-based thermal insulation with a foil coating on one side. For better durability, polished aluminum foil is secured with fine mesh. This reduces the risk of tearing the foil layer along or across. Sauna thermal insulation is available in the form of mats. It is used for insulation of walls, floors along joists and ceilings (floors) of rooms with high humidity. For its production, soda, sand, limestone and a small amount of a binder are used.

Isover Sauna provides reliable thermal protection of the room due to the foil coating. The foil reflects about 95% of the heat back into the room. 5% of the heat passing through it is retained by mineral glass wool. All Izover products have a low thermal conductivity coefficient - 0.041 W/mK, thanks to a large number voids with air between the fibers. Its density is 30 kg/m3.

The use of foil insulation solves two problems at once - insulation and vapor barrier, since the steam that settles on the surface of the foil in the form of condensation drains from it, due to which the glass wool is reliably protected from water. In addition to all this, the absence of the need to install a vapor barrier saves time and labor costs for the construction or repair of a bathhouse or sauna.

Positive characteristics of Izover mats:

ecologically safe material, both for humans and the environment;
have a long service life (subject to the installation and use rules);
non-flammable and frost-resistant;
are not interested in insects and rodents as a source of food;
resistant to alkalis and many acids;
do not shrink throughout the entire service life.

ISOVER insulation not only perfectly retains heat inside the sauna, but is also good sound insulation. Rolls are available in thicknesses of 5 and 10 cm, lengths of 12.5 and 6.25 m, and width of 1.2 m. One package can cover 15 or 7.5 m2. Thermal insulation Sauna from the Izover company has the first degree of flammability (G1), while its base is non-flammable. The destruction of the material begins after the temperature exceeds +400°C. Izover Sauna insulation is used only for insulating wooden surfaces.

Nuances of installing insulation

To install the mats, it is necessary to equip the frame. The recommended distance between the posts is 60 cm. The Izover thermal insulation roll is cut into 2 halves of 60 cm each. This method will ensure reliable fixation of the foil insulation without the use of additional fasteners. The rolls are installed between the racks in a spacer, so that the glass wool completely covers the entire space, without cracks or gaps. Recommended for cutting sharp knife with a blade at least 15 cm long.

Isover mats are installed with the foil side facing the inside of the room. All joints between the rolls are taped with aluminum tape. Thanks to it, moisture will not be able to penetrate the mineral wool. Between foil insulation and interior decoration Be sure to leave a ventilation gap of 1.5-2.5 cm so that accumulated moisture can drain and erode rather than accumulate. To do this, it is necessary to equip a counter-lattice with beams 1.5-2.5 cm thick. Then proceed to attaching the finishing coating.

When working with insulation, you should use products personal protection. Dust generated by fiberglass insulation can cause harm to human health - skin irritation, respiratory tract and mucous membrane of the eyes.

Reviews of Izover products

“A couple of years ago we decided to buy a small a private house with a bathhouse. As it turned out, in order to heat it in winter, a lot of firewood is needed, since the beams have dried out and cracked. There are cracks and drafts everywhere, although we have sealed them most. We immediately realized that we needed to insulate it. Having listened to the reviews of friends, we decided to purchase an Izover Sauna, since this insulation has excellent quality, characteristics and completely affordable price. For our small bathhouse we only needed two rolls. I laid them strictly according to the instructions, cut them in half and placed them in a spacer in the frame. Installation of all mats went quickly and without problems. Now the bathhouse heats up 2 times faster.”

Egor, Ekaterinburg.

"I professional builder And this is not the first time I have used Izover insulation for saunas and baths. I can say for sure that this is high-quality material with good characteristics and density, and I always leave information about it on websites only positive reviews. With proper and competent installation, it can last more than 30 years. The main thing is to ensure complete tightness of all joints using aluminum tape and create a ventilation gap for ventilation. Then the insulation will not deteriorate and the lining will not rot. Izover mats can be easily cut with a regular knife. By the way, when working with it, you must definitely use personal protective equipment, otherwise skin irritation and coughing are guaranteed.”

Alexander, St. Petersburg.

“Reading reviews about the effect of the ISOVER Sauna foil thermal insulation layer, I didn’t fully believe that it could give such a great result. But since my bathhouse needed repairs, I decided to check it out. I bought 100 mm thick thermal insulation, since in our winter it often falls below -30°C. I hired specialists for installation, since I simply don’t have time to do it. I was surprised how quickly all the work was done. It turns out that the rolls do not need to be secured with anything; they are simply inserted into the frame. Already in the first fire of the bath I noticed the result. It heated up faster than before, and the steam lasted a long time.”

Maxim, Nizhny Novgorod.

“We insulated the floor, walls and ceiling in the bathhouse with a sauna. We chose this particular insulation because it is affordable and there are a lot of positive reviews about it. We carried out all the installation work ourselves, since we already have similar experience. Glass wool is elastic, with good density. After unpacking I quickly straightened it out. The mats are easy to insert into the frame. It is convenient that they do not need to be secured with anything, since they themselves sit tightly and securely in the frame. Now to heat up comfortable temperature it takes much less fuel and time. We are very pleased with the result, we don’t regret the effort spent at all.”

Table with prices per roll at which you can buy Sauna thermal insulation from the Izover company:

For convenient transportation, the thermal insulation of the Sauna from the Isover company is compressed 3 times in the packaging. After unpacking, glass wool acquires its original structure within a few minutes due to the elasticity of the material. It can only be transported in covered transport so that it is not exposed to precipitation and dirt. Insulation from the Izover company provides reliable thermal insulation of any room and reduces heating costs. Isover has two eco-labels, including foil insulation.

In buildings such as baths and saunas, there is no constant heating, therefore, for thermal insulation of walls, floors and ceilings, it is recommended to use special material, which can not only provide effective heat and vapor protection, but also create an optimal indoor climate. For these purposes, the universal lightweight insulation Izover Sauna, which is available in compact rolls, is best suited. A modern thermal insulator is a fiberglass cotton sheet different thicknesses(50 and 100 mm), which is covered on one side with a mirror reflector (aluminum foil).

Characteristics

The width of the product is 1200 mm, while the length of the roll and the area completely depend on the thickness of the web:

in mats, the layer of which is 50 mm, roll length – 12,500 mm, area – 15 m2;
with a layer of 100 mm, roll – 6,250 mm, area – 7.5 m2.

Main properties and characteristics Isover insulation Sauna:

On modern Russian market the price of Izover Sauna 50 ranges from 1,550 to 2,000 rubles. Although the cost of this insulation is higher than similar materials from other manufacturers, it is justified by high technical indicators, quality, efficiency and a long period of operation. Insulation Sauna 100 mm provides reliable protection rooms in which heating is completely absent, and is also indispensable for regions with harsh climates. Thanks to excellent technical indicators and quality, sauna insulation with Izover rolls is the most optimal and effective option to date.

Fiberglass cotton mats have a low coefficient of thermal conductivity (0.041 W/m*K), so their presence significantly reduces the cost of energy resources such as firewood, coal, gas and electricity, which are used for heating. Numerous positive reviews about Isover Sauna, which can be read on the Internet, are the main confirmation of its effectiveness.

Thermal insulation of a sauna using Isover

Fiberglass mats are laid with a mirror layer towards the room. At the same time, there must be a space (air gap) of approximately 15-25 mm between them and the interior decoration, which will ensure good air circulation and enhance the effect. The distance between the insulator and the interior trim is determined by the thickness of the spacer beam.

Correct laying of the Izover canvas is carried out between the sheathing guides, and the insulation is fastened using a construction stapler. Thermal insulation will meet all requirements only when the space between the sheathing guides is completely filled with mats. After all installation and fastening work is completed, the joints and seams are taped with special tape made of aluminum foil, thus ensuring tightness. Before you buy Isover Sauna, it is necessary to decide on the type of insulation, since sheets of different thicknesses are intended for different conditions operation. For example, a material with a 50 mm layer is used for thermal insulation storage facilities, metal hangars, as well as in private housing construction: cottages, houses, dachas.

Isover. Which insulation is better: in slabs or in rolls?

In this video you will learn which insulation is easier to work with: in slabs or in rolls. The main characteristic showing the quality of the insulation material is its recoverability. High quality material has the ability to recover to the stated dimensions after opening the package, which was demonstrated in the video. The thickness of Isover insulation, both in slabs and in rolls, after opening the package was restored to 50 mm. To install insulation in slabs, it is necessary to measure the distance between the frame posts. The slabs are ideal for wall insulation with a standard distance between frame posts of 600 mm. When installing slabs, joints are formed that must be covered with a second layer of slabs. It is better to use insulation in rolls when there is a non-standard pitch between the frame posts. First, the distance between the racks is measured, then the unpacked roll is cut to the required size and rolled out along the entire length of the wall. When insulating with rolls, no joints are formed. All Isover materials have increased elasticity and hold securely in the structure.

Isover: How safe are thermal insulation materials?

In this video you will learn how safe it is to use mineral wool for your health and the health of your family. The safety of mineral wool is confirmed by eco-labels, as well as studies in major scientific centers, such as, for example, the Institute of Hygiene. Sysina. In addition to these guarantees Isover company provides an environmental declaration for its products. Thermal insulation based on mineral wool is used in all buildings and structures, including kindergartens, schools, and hospitals. Another sign of the absolute safety of mineral wool is its non-flammability and fire safety, which is confirmed by certificates of compliance with fire safety requirements.

Isover: Which thermal insulation is better: stone wool or fiberglass?

Isover is the only company in Russia that produces mineral wool based on fiberglass and stone wool. The basis of stone wool insulation is melt rocks, and the basis of fiberglass insulation is sand and broken glass, melted at 1000 °C. Materials based on stone fiber are denser than materials based on fiberglass, which is primarily due to the length of the fibers when producing the base for insulation. But density is not a determining parameter when choosing insulation. The main characteristics are thermal conductivity and mechanical characteristics. If we compare materials by area of application, insulation based on both types of mineral wool is divided into three types: Lightweight grades are used in frame structures, for wall insulation, pitched roofs. Such insulation does not take on any load. Hard grades are used in plaster facades, flat loaded roofs. Highly specialized materials are used for soundproofing partitions and for insulating saunas and baths. Materials based on fiberglass are lighter than materials based on stone wool. Due to the length of the fibers, they have greater elasticity, which allows them to fill all the unevenness and voids of the insulated surface, eliminates the formation of “cold bridges” and ensures reliable fixation in the structure. Both types of materials belong to non-flammable materials, do not spread or support combustion. Now that you know the differences between the two types of mineral wool, you will make the correct and objective choice of thermal insulation material for your home.

Isover: Is the density of thermal insulation materials important?

Is the density of mineral wool insulation a decisive characteristic when choosing insulation? You will find the answer to this question in this video. The density of the thermal insulation material affects the thermal conductivity coefficient, strength characteristics and other parameters. But this relationship is not linear. The dependence of the thermal conductivity coefficient on the density of the material is the same for fiberglass and stone wool. For fiberglass based insulation range optimal density, providing a minimum thermal conductivity coefficient of 25-35 kg/cub.m. For insulation based on stone wool - 45-55 kg/cub.m. Thus stone wool capable of providing the same thermal insulation characteristics, but at high densities. Remember that when purchasing thermal insulation materials, we acquire the thermal insulation qualities of the product, and not its density. Even light thermal insulation board made of fiberglass with a density of 60 kg/cubic meter and can withstand heavy loads without deformation. Therefore, when choosing insulation, first of all pay attention to the thermal conductivity coefficient, durability, non-flammability and environmental friendliness.

Although the bathhouse is quite warm design, one room in it needs insulation. We are talking about a steam room, in the walls and ceiling of which an isover sauna is installed. And this material does its job, leaving inside the warmth that is so necessary for this room. This is one of the main reasons for using Isover insulation for a bath.

Isover sauna insulation is a material of mineral origin. Consists of many fibers intertwined. Therefore, the weight of each fabric is quite small, which is achieved by the presence of air space between the thinnest threads. All together gives dense insulation that perfectly maintains the temperature inside the room..

Each canvas has a reflective screen in the form of foil. During the manufacturing process, the metallized component is firmly attached with mineral fibers.

A strong connection is achieved by baking non-woven fabric in special ovens. The foil screen does not peel off from the base even with prolonged exposure to high temperatures.

Does not affect the strength of the connection and the steam present in the given bathhouse.

Foil insulation is available in two versions:

5 cm thick;
10 cm thick.

The thickness of each layer of thermal insulation isover sauna 50 mm is quite enough to retain the warm air left inside the steam room. In this case, no material is required for installation. additional elements. Isover sauna 50 insulation is simply inserted between wooden blocks frame.

The canvas has a width of 120 cm, so before installation it should be cut into two equal parts. To do this, use a construction or stationery knife with a blade length of at least 100 mm. Halves 60 cm wide are necessary so that the frame of the walls or ceiling does not have large sagging. The distance between the bars in this case should be no more than 59 cm. The joints and the slats themselves should be sealed with special metallized tape.. Thus, the aluminum heat-reflecting screen will be solid and monolithic.

Cost of Izover for a bath

The cost of thermal insulation for an isover sauna directly depends on its thickness. But this is not the only factor influencing the price. of this product. Much depends on the company offering this product to the buyer. When comparing the performance of different sites, it is worth highlighting the following data:

foil insulation for baths isover 50 mm thick with a price from 1658 rubles;
foil insulation for isover baths 100 mm thick with a price from 1850 rubles.

When purchasing thermal insulation, you should more carefully study the sellers' offers. This is important because the product may not be in the company's warehouses.

Reviews about Isover sauna insulation

Isover sauna quality products are enjoyed in great demand from builders and owners country houses. Many people share their impressions about this material. To finally make sure of the reliability of thermal insulation for baths, you should listen to customers.

I was very pleased with the thermal insulation of Isover for baths. There is no need to invent new methods of vapor barrier for walls and ceilings. Everything is convenient. The roll already contains both insulation and a reflective screen. Installs quickly and does not require additional investments in fasteners. The vapor permeability is amazing. The only disappointment is the price of the roll. I wish it was cheaper.
Zinaida. Naberezhnye Chelny

My husband and I built a bathhouse at our dacha. And we decided to try isover for a bath. I liked this foil thermal insulation because it is convenient to work with. My husband quickly insulated the ceiling and walls. Problems arose only with the joints. The adhesive tape came off the surface of the metal screen in several places, but they took another one and fixed everything. The thermal insulation itself serves faithfully. It is always warm in the steam room, and even in the bathhouse itself, no matter what the weather is outside.
Olga. Moscow

On the advice of friends, I decided to buy an isover when I built a bathhouse. I insulated the steam room so that it wouldn’t blow and you could steam in peace. I'm pleased with the result. He insulated everything quickly. The material is easy to work with. Flying fiberglass particles cause inconvenience. I do not recommend laying sheets without special gloves and a respirator. Otherwise, I have no complaints.

Isover Sauna is a multifunctional fiberglass-based insulation with a thermal and steam reflective side. The main purpose is thermal insulation of baths and unheated rooms with high humidity, but if desired, it can be purchased for pitched roofs, protection of pipe communications, air ducts and equipment. According to reviews, the maximum effect of insulation with this building material is observed in cold climates, and significant savings in energy resources for heating are achieved. Installation of Isover mineral wool is not difficult; all work can be done by one person; a regular construction stapler is used for fixation.

Isover Sauna insulation is produced in the form of light, elastic mats made of fiberglass threads, laminated on one side with polished aluminum foil. To enhance the tensile strength characteristics of the reflective coating, a fine-mesh reinforced mesh is used. The structure of the insulation allows threefold compression; packaging with thick shrink film is very convenient to transport. After unpacking, Isover quickly accepts the required form and retains it throughout its entire service life. This brand is resistant to temperature changes and protected from moisture and hot steam, when correct installation it prolongs the durability of walls and ceilings in a sauna or bathhouse.

Description of material

The advantages of Izover Sauna include sound absorption, hygiene, safety, minimal thermal and steam conductivity. The insulation is resistant to rotting and other biological influences. Installation of Izover mineral wool on wooden walls baths and saunas can reduce heat loss by almost three times (from 52 to 18 W/m2) and, importantly, protects them from the penetration of hot wet steam. To the main operational characteristics foil insulation includes:

Thermal conductivity coefficient is within 0.041 W/m K.
Density – 11 kg/m3.
Recommended base material is wood.
Flammability group – G1.
Standard sizes: width – 1200 mm, length – 12500 and 6250, thickness – 50 and 100.

Insulation Isover Sauna matches international standards quality EN 13162 and ISO 9001, customer reviews are mostly positive. A huge advantage is the saving of time during the construction process, since the layers of thermal insulation and vapor barrier are laid simultaneously. Mats do not release toxins under the influence of temperature changes and belong to the low-flammable group of building materials.

Installation nuances

Manufacturer's declared scope of application: interior walls baths and saunas, but according to reviews, Izover foil insulation of this brand is often used to protect floors and ceilings, creating a kind of “thermos effect”. Opinions are divided: the density of the mats, in principle, is not high enough to insulate the lower horizontal floors, but in practice, buying a homogeneous insulation in bulk helps save money. How colder region, the thicker the mineral wool you need to buy, this is also true for periodically heated buildings. The main rule for installing Izover is to lay the foil side inside the room; violation of this condition is considered a gross technology error. The rolls are unpacked no earlier than 30 minutes before the start of work; after removing the packaging, the mineral wool should take its volume.

Fastening is carried out exclusively on wooden sheathing, it is advisable to slightly press the edges of the thermal insulation. The reinforced aluminum layer is fixed with staples; it is recommended to glue the seams and joints with reflective tape. It is advisable to think over the placement scheme and cut the mats in advance; the main requirement is to completely fill the space between the battens. Important nuance: between the foil layer Isover thermal insulation Sauna and external finishing a mandatory air gap of 15-25 mm is provided. To protect against heat loss in ordinary warehouses or summer cottages, it is advisable to buy a thinner Izover, this is especially true when arranging suspended ceilings. An insulation thickness of 50 mm in this case will be quite sufficient.

Reviews from people

“I live in a cold region, for the arrangement of the sauna I chose Isover foil insulation with a thickness of 100 mm, laid mats on the floor, walls and ceiling. After the first year of operation, I disassembled the casing and checked the condition of the material; the shape and density had not changed.”

Pavel, Moscow.

“I advise you to purchase foil Izover for self-insulation of sauna walls based on my own experience, it can be cut into pieces without any problems the right size and is simply fixed to the sheathing with staples. It is worth placing a membrane on the ceiling under the insulation, then the bathhouse will be protected to the maximum. According to reviews, such cladding reduces heating costs by three times, but I cannot confirm this, since I did thermal insulation work immediately after the walls are built.”

Roman Startsev, Moscow region.

“I provide construction services To the population, I confidently recommend Izover insulation for saunas and baths. The material has many advantages: it is easy to cut and fix, the insulation characteristics are quite durable, the surface is well protected from steam and heat loss. In addition to the cost of the roll, the costs include the purchase of foil tape; I do not recommend leaving the joints open. The most problematic area is the ceiling of the steam room; it is important to ensure its maximum tightness and not forget about the ventilation vents.”

Alexey, Novosibirsk.

“For thermal insulation of the sauna, I bought rolls of Izover glass wool with a reflective layer, overall I was pleased with the material. I attached the mats to the walls myself; there were no problems during installation and operation. Steam protection is reliable, heat loss is minimal. I think the only negative is the high cost, the price per roll was 1,500, 1 m2 cost 210 rubles, and this does not include adhesive tape and staples.”

Philip, Yekaterinburg.
