Premium XPS Polystyrene Board – High-Performance Wall Insulation Solution
Thick, dense XPS foam core provides superior thermal resistance (R-value) and moisture resistance, ideal for extreme climates. Factory-direct OEM production ensures precision-cut edges and uniform density for seamless installation.
High compressive strength (15-18 psi) supports heavy structural loads in basements, roofs, and flooring systems. UV-stabilized surface resists degradation in exposed applications like exterior wall cladding.
Lightweight yet rigid panels (2"x4" or custom sizes) enable DIY-friendly handling with scored edges for snap-cutting. Zero formaldehyde emission passes LEED certification for eco-conscious projects.
Trusted by contractors for cavity walls, under-slab insulation, and cold storage facilities. Bulk discounts available for wholesale construction orders.

I have a few bumps with OKWISHING previously. But the reason I have come back are prices and current styles. With 3 girls, youth to teen, OKWISHING is very friendly. That being said, the last two times I have ordered prompted delivery, good communication as well fit matched the description. Thank you for working on your costumer service.
