The best stone wool insulation - manufacturers and brands overview

One of the most common types of insulation is stone wool. Its second name is a basalt slab. The material does not burn, is easily cut to the required dimensions and does not affect the foundation due to its light weight. But today there is such a wide variety of manufacturers and brands of this type of insulation that it is sometimes very difficult to make a choice. Therefore, we compiled a rating of stone wool insulation, showing which stone wool is best suited for a particular application.

The selection of goods was carried out on the basis of reviews, opinions and ratings of users posted on various resources on the Internet. All information is taken from public sources. We do not cooperate with manufacturers and trademarks and do not call for the purchase of certain products. The article is for informational purposes only.

Paroc is a Finnish brand with a rich history

One of the leading European manufacturers of stone wool is the company Paroc, which has been producing products of the same name for about 80 years. The company itself is part of the large Owens Corning concern. Paroc is headquartered in Finland, while other offices are based in 13 more countries.

The main types of products are insulation and refractory materials for buildings under construction and reconstruction, various types of insulation for repairs, acoustics, insulation of ships and industrial premises. The brand colors of the packaging are bright red and white, which is recognizable in 40 countries where their products are sold.

Paroc basalt slabs have a long service life and low thermal conductivity, but for each specific place of use, you should choose a product from a certain category. The manufacturer has specialized lines of basalt insulation for facades, roofs, foundations and general thermal insulation.

General construction stone wool insulation

When reconstructing a part of a house or building a new one, it is necessary to warm up many parts at once: floor, roof, facade, attic. If the region is cold, then additional insulation on the walls inside is required. Buying a lot of specialized materials for a particular installation site is sometimes unprofitable. Sometimes it is better to choose among universal heaters, which have average indicators and characteristics that allow you to use them anywhere.

In this insulation category, Paroc has four types of cotton wool:

• eXtra - Great for walls, roofs and floors. It does not burn and easily fits at any angle. Differs in low shrinkage.
• eXtra light - similar in properties to the previous one, but stands out with its light weight, which is well suited for warming various parts of frame houses so as not to add weight to the structure. Her thermal conductivity does not decrease from this and is 0.038 when exposed to a temperature of 10 degrees.
• eXtra plus - This is a more expensive version of the insulation related to the premium class.In addition to fire protection and sound insulation, it even more restrains the transmission of low temperatures due to the thermal conductivity of 0.034.
• eXtra Smart - has the same properties as other universal plates in this category, but also has increased flexibility without losing elasticity. Such stone wool is the best for isolation in hard to reach places.

Thermal insulation Paroc for plaster facades

If it is planned to decorate the building with a layer of plaster from the outside, then insulation of the facade is required with cotton wool, which can withstand the subsequent load from the applied mortar. For this, Paroc produces basalt slabs of a separate category with the names Fatio and Linio. These materials are resistant to the alkaline environment inherent in stucco mortar, and therefore are not subject to shrinkage or corrosion. Installation is carried out using a steel reinforcing mesh, which increases the strength of the facade and the reliability of fixing of facing materials.

The Linio range of stone wool is available in indices from 10 to 80, which implies the tensile strength of the surface on the outside. The value in kPa is measured and determines which layer of plaster can be applied to the slab. The thicker the decorative finish with cap materials, the higher the number should be in the name of the basalt wool of this category. The surface of the insulation is specially made especially smooth so that it is easier to level the subsequent layer of plaster on it.

Paroc thermal insulation for flat roofs

A flat roof has its own characteristics - it needs reliable insulation, able to withstand both the pressure of water and snow, and waterproofing materials and users passing through it to perform work or other technical purposes. To do this, Paroc produces a special category of stone wool series ROB and ROS. Plates and rolls of insulation have a height of 60 to 180 mm.

They withstand temperatures up to 200 degrees without loss of useful properties, which is optimal for roofs exposed to heating in direct sunlight. After 200 degrees, binders begin to evaporate, but the cotton wool remains intact even up to 1000 degrees.

To support the weight of various materials and precipitation, this type of product is produced with a digital designation. For example, the ROS 30 is able to tolerate masses of up to 3,000 kg per square meter. The top layer of the basalt slab is specially designed to be more rigid, well suited to cover with subsequent building materials. Vata is completely non-combustible and remains stable in size at various temperatures, is not prone to drying out and the formation of cold bridges. ROS 60 and 80 can withstand loads on the top layer in the range of 6000 and 8000 kg / m2.

Paroc thermal insulation for foundation and ground flooring

When warming the foundation and the foundations of floors on the ground, a heater is needed that protects not only cold, but also dampness, and the insulation layer itself should not be destroyed in such an environment during long-term operation. Stone wool Paroc GRS 20 is specially designed to meet these conditions. It is hydrophobic and the effect of water does not affect it.

Great for warming different foundations or floors, both basement and first floor. Stone wool is quite durable and can withstand up to 2000 kg / m². Thermal conductivity at the level of 0.042 W / (m * K) provides decent insulation from freezing temperatures.

Paroc thermal insulation for walls

For wall insulation, the manufacturer has two series of stone wool: WAS and WAB. The first has a thickness of 40 to 200 mm with a density of up to 30 kg / m³. It maintains dimensional stability and is completely non-combustible. Thermal conductivity within 0.039 W / (m * K).

There are some modifications with special durability, for example WAS 50t and WAS 30 tb, which are equipped with fiberglass lamination. This protects the fibers from delamination. WAS 35 is well suited for double-layer insulation with the creation of an air gap, or it can act as an outer layer in combination with thick brick walls. On the contrary, the WAB 10t basalt slab is produced in thin 20 mm and does not create a load on a light frame.At the same time, it can withstand temperatures up to 750 degrees.

Rockwool stone wool for private homes and apartments

For private housing construction, the manufacturer has a whole line of stone wool insulation. The most popular among them are such heaters as:

• LIGHT BATTS
• SAUNA BATTS
• ACOUSTIC BATTS

LIGHT BATTS are lightweight mineral wool boards designed for thermal insulation of non-loaded structures in the insulation system of a house or apartment. The thermal conductivity of this insulation is 0.036 W / (m · K). It can be used to warm a large number of objects: mansard rooms (pitched roofs), partitions, flooring along logs, walls faced with siding, frame walls, balconies, baths, saunas

SAUNA BATTS - these are basalt slabs having a density of 40 kg / m³ and can be used both on the ceiling and on the walls. A feature of the insulation is a one-sided coating with aluminum foil that does not pass steam and water. This protects the fibers from getting wet and shrinkage, and also completely blocks the heat output from the room. Using such cotton wool in a bath or sauna, it will turn out to ensure the preservation of temperature and the integrity of the partitions. In this case, installation of a vapor barrier is not required, which reduces construction costs. The material withstands up to 200 degrees without loss of properties.

Stone wool ACOUSTIC BATTS has a pronounced sound absorption effect, therefore it is optimal for insulation of walls and ceilings in the apartment, which provides comfort and increases fire safety. Suitable for all types of residential and non-residential premises, installation in suspended ceilings is allowed. The sound absorption index for a layer of 50 mm is 0.8 according to GOST 23499-2009. A thickness of 200 mm provides sound absorption class A with an index of 1.0. The density of such basalt plates varies from 35 to 45 kg / m3.
