🔥 Yes, he’s torching membrane directly onto the insulation.
With standard materials, this is a roofing nightmare. With Stiferite Class B, it’s just another Tuesday.
If you’re insulating a flat terrace roof, here is why this changes the game for your next project:
- Zero Melting: Unlike EPS or XPS (which literally melt under a flame), Stiferite Class B is a high-performance PIR panel that withstands up to 200°C.
- Built for Direct Torch: The specialized bituminous mineral fiberglass facer allows installers to torch the waterproofing membrane directly to the insulation.
- Heavy Duty: It easily supports the weight of installers walking on it (no crushing, no warping).
- The Bottom Line: You save time, eliminate extra layers, and get a rock-solid, high-efficiency roof that lasts.
