XPS Insulation Board Groove-and-Tongue Edge 30 kg/m³ B1
Groove-and-Tongue XPS Board 30 kg/m³ B1 eliminates joint thermal bridges for seamless insulation in cold storage rooms, flat roof systems, and commercial curtain wall cavity insulation applications.
// Key Features
- Four-side tongue-and-groove edge profile eliminates thermal bridging at all board-to-board joints
- B1 flame-retardant rating ensures fire compliance in continuous insulation assemblies
- Self-aligning interlocking edges accelerate installation speed and reduce on-site labour cost
- Closed-cell 30 kg/m³ core maintains stable 0.030 W/(m·K) thermal performance over service life
