Materials & Processes
Rock wool
Non-combustible insulation for cavity blowing, inhibits the spread of fire and sound transmission.
Cellulose fibres
Slow-burning, ecologically safe insulation material with mineral salts.
Perlite
Core insulation of double-leaf masonry, also for areas at risk of moisture.
Wood fibres
Fire-resistant insulation boards that withstand a fire for at least 90 minutes.
Silicone sealant
Elastic joint sealing for natural stone, ceramics, glass, concrete and metal.
Hybrid sealant
Paintable joints in structural, civil and window construction, also with quartz sand.
Epoxy resin
Seamless floor coatings from decorative to highly mechanically and chemically resistant.
Polyurethane
Seamless, weather-resistant coatings for balconies, terraces and flat roofs.
Fire protection mortar
Sealing of cable, plastic, metal and ventilation pipe penetrations in openings.
Fire protection collar (expanding laminate)
Compresses combustible pipes when exposed to heat and seals floor penetrations.
