Products for building
Insulation and building films comprise a group of products used for various insulation purposes in construction. Marma Polskie Folie's products from this category are employed in buildings from foundations to roofs. They serve as moisture insulation (Izol Bud films), anti-condensation (Vapour Regulator), and actively manage water vapor (high vapor-permeable membranes - Dachowa and Ekrany Dachowe).
![<p style="text-align: justify;">Each roll of Vapour Regulator is equipped with self-adhesive tape placed in the overlap zone to facilitate connecting following layers of the product. The tightness of the layer created by Vapour Regulator in building partitions is very important for the energy efficiency of entire buildings. This results from our experience and experiments, which prove that a lot of heat escapes through draughty roofs and walls. Uncontrolled air flows additionally moisten these partitions.</p>
<p style="text-align: justify;">It is worth noting that by using Vapour Regulator we can achieve full air tightness when it is also stuck together with walls, chimneys, floors and other elements of the building.</p>
