The light system of density approx. 12kg/m3 is used primarily for insulating and mute attics as well as the walls of the housing frame construction. Spraying is carried out from inside, before drywall is installed. The polyurethane foam affixed to the surface increases its volume of more than 100-times within 5-8 seconds. This makes the perfect filling for hard-to-reach places on attics, especially in places such as support for the roof, or in other hard-to-reach places, with a complex roof structure.

The material of this density is max. 40% closed cells, that provides a 'breathing' insulation layer.
      The most important feature of using the method of isolation is to ensure the tightness sprayed structure. This is a very important aspect, especially for energy-efficient home construction.

Polyurethane foam by filling in, does not fall under the influence of gravity, its attachment is unnecessary, which significantly reduces the execution time of insulation. In addition, the high viscosity of spray foam at the time, is bonding parts of the structure, strengthening it, which is very important for buildings exposed to strong gusts of wind.
