Rock wool strip

Rock wool strip

Rock wool strips are cut from high-strength rock wool panels, so they have high compressive strength and excellent fire resistance. Rock wool strips are generally used as filling materials for rock wool sandwich panels and provide good fireproof performance for wall panels and roof panels. Various specifications of products produced by chemical dry glue mixture and mechanical curing technology have made important contributions to the creation of a constant temperature thermal insulation and sound insulation good, safe and high quality exterior wall. Made of a specific structure, it has high compressive strength and excellent fire resistance.

Unit weight: 100-200kg / m3; length: 1000-1200mm; width: 50mm, 80mm, 100mm;
Thickness: 28mm, 36mm, 40mm, 50mm, 75mm, 80mm, 100mm, (fiber vertical direction); special size, bulk density and thickness can be customized according to customer requirements.
Property: thermal conductivity (metal plate) 0.040w/m.k
Sound absorption / insulation: the open structure of rock wool provides excellent sound absorption / insulation performance.
Fire resistance: the product is non combustible according to ASTM e-136.
Compressive strength: rock wool strip is made of profiled plate. The fiber is upright in the assembly line process, so it can bear high load.
5%: pressure resistance > 25kpa; 10%: pressure resistance > 40kpa.
Moisture resistance: rock wool strip is waterproof and has good ability to release water vapor pressure to roof structure.
Chemical and biological characteristics: the pH value of rock wool is 7 or slightly alkaline, and it meets the requirements of astm-c-795 and jis-a-9504, so it can not normally meet the growth of mold, fungus and bacteria.
