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.
