Insulation of beam gaps Pilisborosjenő

PUR foam (polyurethane foam) insulation is the most effective solution for interior insulation of the attic space between the beams. Below are a few reasons why PUR foam insulation can be beneficial:

Excellent thermal insulation properties: PUR foam is a very good thermal insulation material that effectively reduces heat loss and the formation of cold bridges. The foam consists of small pores that prevent heat flow and thus help equalize the temperature in the attic.

Air sealing effect: PUR foam insulation perfectly seals the air gaps and cracks between the beams. This reduces the formation of thermal bridges and eliminates heat loss by preventing cold air from entering the attic.

Water resistance: PUR foam is non-absorbent, so it will not get wet or lose its effectiveness even when exposed to moisture. This can be an important consideration in attic rooms where moisture can cause problems.

Sound insulation: PUR foam not only provides thermal insulation, but also has excellent sound insulation properties. The foam absorbs and dampens noise, thus reducing the penetration of external noise into the attic.

Durability and easy installation: PUR foam is a light but durable material that ensures a long service life. In addition, it can be easily installed between the beams, as it is sprayed on in liquid form and then develops to fill the voids and gaps.

 Why is it better than cotton?

Cotton is also popular for insulating the beam gaps, a frequently used and effective solution for the interior insulation of the attic. However, due to several factors, it may have some disadvantages compared to PUR foam:

Thermal conductivity: The thermal conductivity of cotton insulation materials is generally higher than that of PUR foam. This means that cotton reduces heat loss less effectively and larger thermal bridges can form in the structure.

Water and vapor barrier: Cotton insulation materials are not waterproof and can absorb moisture. This moisture can cause mold and rot in the long term, as well as impair their insulating ability.

Space utilization: Cotton insulation requires a thicker layer to achieve adequate insulation performance compared to PUR foam. As a result, it takes up more space in the attic and reduces the usability of the interior space.

Installation difficulties: Cotton insulation materials are generally stiffer and more difficult to handle than PUR foam. This can cause additional difficulties during installation, especially if the areas between the beams are difficult to reach.
