rock wool or glass wool make an important contribution to a safe and high quality exterior wall with a constantly high thermal insulation and acoustic control.
Note: 1.Thermal conductivity (metal deck): 0.040W/mk 2. Sound absorption: lamellas open structure provides extremely good acoustic absorption/insulation performance. 3. Compressive strength: 5% compression >25kpa 10% compression >40kpa 4. Fire resistance: no-combustible when tested to ASTM E-136 5. Moisture resistance: waterproof and have good vapor pressure release capacity to the roof construction 6. Chemical properties and biological properties: mineral wool is neutral (PH7) or slightly alkaline and meet the requirement of standard ASTM C 795, JIS A 9504. It will not normally support the growth of molds, fungi and bacteria.
