Cellulose insulation is used in wooden and masonry buildings, in new, renovated and thermo-modernized constructions, in single- and multi-family residential buildings, in public facilities. In inter-floor ceilings, on the ceiling of the last storey - in the roofed roofs and in the roof slopes, the method of blowing or inflating dry cellulose insulation is used. In vertical partitions it is also possible to use the spray method (cellulose insulation moistened with a small amount of water installed between the elements of the structure), which in a special way insulates walls without thermal bridges - the thermal insulation layer can be fully inspected before covering.
The inflatable or sprayed material fills the entire space defined in the design regardless of its shape. You can fill embarrassing gaps or voids, also behind the screens and installation plumbs, by the way, by warming the wires in them. In the case of renovation and thermo-modernization with cellulose insulation, the voids and losses of existing thermal insulation can be supplemented under pressure. The thermal and humidity conditions of old buildings improve the insulation from the outside, and then insulation from the inside is also possible.
Useful parameters put cellulose insulation at the forefront of commonly used thermal insulation materials. The thermal conductivity of the material (lambda) is 0.039 W (m K). Therefore, the heat transfer coefficient U for a wall insulated with 15cm cellulose insulation is less than U = 0.25 W / m²K and with a thermal insulation layer thickness of 25cm, this coefficient is U = 0.16 W / m²K. Applying a thickness of 42.5 cm in the flat roof, a U-value of 0.10 W / m²K can be obtained. Such thermal insulation parameters are found in Scandinavian solutions. Heat losses using this material may be lower in comparison with other materials due to the continuity and tightness of the insulation as well as reducing the risk of point moisture insulation, which has a significant impact on the thermal insulation properties of the barrier.
The material used is characterized by low air permeability with a high air content (70-80%) due to the porous fiber structure and moisture resistance with simultaneous hygroscopic properties that allow the regulation of humidity in the rooms due to the absorption and moisture transfer through the entire insulated structure building. Cellulose wool binds and releases moisture in a similar way to wooden, ceramic or gypsum building elements. It also allows free evaporation of technological moisture from building elements drying out on the building site.
To achieve the proper interior microclimate, a plastic vapor barrier layer is not used. In some cases, to avoid damage to the material, windproof water vapor insulation from the outside can be used and the paper coating inside. Cellulose wool is characterized by constancy of thermal insulation properties - it adapts to variations in humidity and air temperature while maintaining its thermal properties up to the humidity level of 12%. According to studies carried out in buildings (humidity of the material under normal air humidity 50% is about 5% and with inhospitable humidity in rooms reaching 70 - 80% the humidity of the material is 11%).
The insulating material creates a layer of insulation that adheres seamlessly to the structural elements of the building, preventing uncontrolled movements of the air. Cellulose insulation sprayed, after drying becomes homogeneous and elastic. Continuous bridgeless insulation allows for controlled, energy-saving ventilation. It limits the flow of warm air only to specially designed for this purpose openings (doors, windows, ducts). In the gas exchange (water vapor and other gases) in the well insulated building with barriers insulated with cellulose wool, all external partitions (housing of the heated volume) participate. This exchange is not carried out by convection but by diffusion. As research shows, leaving the surface of open barriers for gas diffusion supports natural ventilation of rooms, especially in the absence of other solutions provided in this regard.
Cellulose insulation can be used in buildings to suppress sounds. It is filled with light partition walls, ceilings. Using cellulose insulation, you can make acoustic screens and sound absorbing surfaces. The wool can be sprayed even on the ceiling surfaces using an admixture of harmless glue.
Cellulose insulation is a non-flammable material - resistant to external fire, not spreading fire. Resistance to fire is obtained thanks to the boron compounds contained in the material and characterizing the structure of the material
