What is ThermoMC?

Thanks to a special cellulose blowing method, it can be successfully used in new, renovated, and thermally modernized masonry buildings, achieving so-called “seamless insulation” without thermal bridges.

It is perfectly suitable for loose filling in unused attics, flat roofs, blowing into closed partitions (external walls, partition walls, roof slopes).

The spraying method can also be used (cellulose wool moistened with a small amount of water and binder), the cellulose wool layer can be fully inspected before covering.

The blown or sprayed material fills the entire space regardless of its shape. Cellulose wool can fill installation shafts, simultaneously insulating the cables running inside.

In the case of renovation or thermal modernization, cellulose wool can be used to fill gaps in existing thermal insulation. Thanks to its hygroscopic properties, cellulose wool improves humidity conditions in old buildings.

Cellulose wool, thanks to its excellent technical parameters, is at the forefront of commonly used thermal insulation materials. ThermoMC cellulose wool has a thermal conductivity coefficient of 0.037 W(mK). According to new provisions of the Regulation on technical conditions which buildings and their location should meet, effective from January 1, 2014, they are as follows:

Effective date	Heat transfer coefficient U (W/m2K)	ThermoMC insulation layer thickness (cm)
from December 31, 2013	0.25	16
from January 1, 2014	0.20	20
from January 1, 2017	0.18	22
from January 1, 2021	0.15	26

The table shows the heat transfer coefficients of ventilated flat roofs and the corresponding thicknesses of the ThermoMC insulation layer.

ThermoMC cellulose wool at 16 cm thickness has a heat transfer coefficient U of 0.25 W/m2K, and at 26 cm insulation layer thickness, this coefficient is U = 0.15 W/m2K. If we applied an insulation thickness of 40 cm in a ventilated flat roof, we would achieve a U coefficient of 0.10 W/m2K; such a low heat transfer coefficient allows for very high energy efficiency. Such solutions are widely used in Scandinavia with great success, and residents of such insulated homes enjoy comfort and pay less for heating the building. Cellulose wool stands out excellently among other insulation materials; heat losses when using this insulation will be significantly reduced thanks to the continuity and tightness of the “seamless” insulation.

The ecological thermal insulation material is characterized by low air permeability with a very high air content of about 70% in its structure. Thanks to this structure, cellulose fibers exhibit high moisture sorption from the air while also having hygroscopic properties, which allow the material to release moisture absorbed from the air and building structures. In the case of cellulose, there is no need to use plastic vapor barrier foils; windproofing can optionally be applied on the exterior side of the building, and cellulose on the interior side.

Additionally, cellulose wool can absorb moisture up to 15% of its volume without losing its insulating properties, all thanks to the air trapped in the insulation layer. This happens because cellulose wool has a fibrous structure, and its fibers can absorb water, unlike mineral wool fibers, which come from rock and cannot absorb moisture. Thanks to its countless advantages, cellulose insulation excellently facilitates vapor exchange throughout the insulated attic. According to studies conducted in buildings (material moisture under normal air humidity conditions of 50% is about 5%, and under unfavorable indoor air humidity of 70–80%, material moisture reaches 11%).

Cellulose wool forms a seamless insulation layer, unlike other insulation materials in the form of boards. When installing insulation boards, thermal bridges often occur at the joints of the boards. Cellulose is installed using a pneumatic blowing system precisely for this reason, guaranteeing the avoidance of all thermal bridges.

Noise protection

Insulation made of cellulose wool has excellent sound damping properties. By filling partition walls, ceilings, or floors on joists, we free ourselves from noises from neighboring rooms. Seamless surfaces absorb sound waves, significantly reducing reverberation in rooms, minimizing disturbances, and creating an undisturbed, clean sound image.

Fire protection

ThermoMC is a material that during a fire does not emit any toxic substances, does not burn but only undergoes slow charring. The main cause of health damage during fires is not the flame itself, but toxic smoke and various toxic substances contained therein; therefore, our material, thanks to its hygroscopic properties and retardant impregnation, is the best fire insulation as well as excellent protection against various insects, fungi, and rodents. Insulation made of impregnated cellulose wool does not provide food or habitat for rodents. Another very important advantage of the product is that during a fire it excellently protects building structures, both steel and wooden.

Wooden structures insulated with ThermoMC cellulose will be safer because the material provides rapid removal of excess moisture from the wood and transfers it across its entire surface. Thanks to the fibrous structure, cellulose stores water while the air voids remain empty, ensuring that the insulation does not lose its insulating parameters. ThermoMC can absorb water up to 15% of its mass. Mineral wool, unlike cellulose, does not absorb water but stores it between its fibers, replacing air and reducing the thermal insulation of the partition.

Protection against fungi and pests

Houses insulated with cellulose wool, as statistics show, are much less prone to dampness and therefore do not develop fungi or mold.

A common problem in inhabited attics are unwanted guests such as martens or weasels. Insulation made of impregnated cellulose wool does not provide food or habitat for rodents. Cellulose wool protects our attic and ensures peace and quiet.

Natural insulation

The natural raw material for producing ThermoMC cellulose wool are cellulose fibers, which our company obtains in the form of newspapers. The material is made from recycled raw materials such as papers and newspapers, thus our company’s solutions contribute to the protection of forest resources and reduce the consumption of fossil energy sources through production processes that allow limiting CO2 emissions. Cellulose wool is the first tested and ecological insulation material that is fully environmentally friendly throughout its entire existence, starting from production and ending with disposal.
