Product Q&A
Q:Difference between rock wool and polyurethane sandwich panel?
A:
1) Core: Rock wool is inorganic fiber, polyurethane is organic foam. 2) Fire: Rock wool is Class A non-combustible (>=1000C), polyurethane is Class B1 (200-300C, toxic gas). 3) Insulation: Polyurethane is better (0.023 vs 0.044 W/mK). 4) Sound: Rock wool has superior sound insulation/absorption. 5) Price: Rock wool is 20-30% lower. 6) Use: Rock wool for high fire needs; polyurethane for cold storage.
Q:What is rock wool sandwich panel fire rating?
A:
Combustion performance is Class A (non-combustible) per GB 8624-2012. Rock wool core is inorganic non-combustible (>=1000C). Overall panel is Class A (A2), smoke-free, non-toxic. Fire resistance limit: 50mm panel is 0.5-1 hour, 100mm is 1-1.5 hours. Polyurethane is Class B1, foam is Class B2.
Q:How to choose rock wool sandwich panel thickness?
A:
Selection basis: 1) Insulation: 50mm (K~0.8), 75mm (K~0.55), 100mm (K~0.42), 150mm (K~0.28). 2) Fire: High fire needs (clean rooms) use 100mm+. 3) Sound: High sound needs use 75mm+. 4) Application: Roof uses 75-100mm, wall uses 50-75mm. 5) Economy: Prioritize thinner specs to reduce cost while meeting requirements.
Q:What are rock wool sandwich panel installation steps?
A:
1) Layout: Mark purlin positions and starting line. 2) Lifting: Lift with crane, lay piece by piece. 3) Fixing: Secure with self-tapping screws, connect via male/female slots. 4) Sealing: Seal seams and laps with sealant. 5) Edge Trim: Install trim and flashing. 6) Inspection: Check flatness and firmness. Safety: Anti-slip, no work in bad weather.
Q:MOQ and lead time?
A:
Stock from 10 sqm, 3-7 days lead time; common sizes (50/75/100mm, 950mm) available for same-day pickup. Special thickness (120-200mm), colors, or custom lengths require 500 sqm minimum and 7-15 days lead time. Custom services like cutting and bending are available.
