Nonwoven material Spunbel is not toxic. Its use at the temperature not more than 150o C does not require of precautionary measures.
Application: SK – as insulating material for roofs under any kind of covering (tile, metallic roof, roofing slate etc.). Material use for any type of construction for protection wind, dust, atmospheric moisture; SKL – as vapor resistance membranes in the bottom layer of a roofing carpet of buildings and constructions, for a waterproofing from an earth moisture of buildings and constructions and for protection against saturation by a capillary moisture of various designs
Packing: material is made in rolls (weight of roll is not more than 500 kg), it is reeled on paper cartridge and it is wrapped in polyethylene film.
