Modern construction demands smart thermal management. DONGYUAN SEVEN’s 2-inch rigid foam insulation boards combine cutting-edge materials with CE-certified engineering to create airtight barriers against heat transfer. Unlike conventional insulation panel boards, our 50mm acoustic insulation variants simultaneously reduce noise pollution by 28dB while maintaining R-values up to 6.5 per inch. Architects globally specify our solid insulation boards for projects requiring fire-resistant cladding systems with integrated thermal breaks. From 25mm budget-friendly options to custom-thick insulation solutions, we help contractors balance upfront insulation board prices with 20+ year ROI through reduced HVAC loads.
