Heat insulations

Polyurethane heat insulation  is sprayed in the form of two materials, isocyanate and polyol, which create polyurethane due to reaction and foaming agents are added to form foam.
From the viewpoint of foaming we distinguish:

  •  Open cell structures – more than 80 % of open cells, density 8 -15 kg/m3
  •  Semi-rigid foams – density 30-45 kg/m3, strength about 270 KPA
  •  Rigid – density 50-70 kg/m3, strength 400-500 KPA

With sprayed thermal insulation foam you will achieve high saving at heating (saving approximately 70%). Apart from the saving, also the costs of the implementation of the heat insulation layer are reduced due to the possibility of quick application of the foam (approximately 200 m2 in one day).

Advantages – there is no significant change of fysical characteristics due to humidity. Polyurethane does not absorb water, or if it does, then only into cells and lambda changes minimally, max. 0.04. With Nobasil there is a change up to 0.08. Due to physical inputs and air exchange there is a change, e.g. with Nobasil, but with polyurethane only minimally. When wind is blowing, then with the application of other materials, e.g.
Interior – soft foams are used for interior insulation.
Advantage of heat insulation of flat roofs – adhesion, strength. After spraying to the original roofing it is not necessary to anchor and so we do not make unwanted transitions. From the viewpoint of insulation characteristics it by 50 % better, there are no transitions at connecting, insulations are quickly implemented and it smoothly solves details – drains, transitions, end-to-wall terminations etc.
For the heat insulation of floors and heat insulation of foundations our company uses middle-hard foam (ekonomic solution).
The most frequent objects where we implement heat insulations of industrial structures include pipelines,  silos, energy channels.
