25mm Xtratherm Safe-R is an exceptional rigid insulation solution with enhanced fire performance. It features a Class O phenolic foam core that emits negligible smoke obscuration. The insulation is clad with low emissivity aluminium facings on both sides, achieving a remarkable thermal conductivity as low as 0.021W/mK.
APPLICATION
- Framing board
- Pitched roof insulation
- Rainscreen insulation
- Soffit insulation
- Solid and suspended ground floor
Proper storage of 25mm Xtratherm Safe-R is essential. It should be elevated above the ground, placed on a clean and flat surface, and covered to protect it from outdoor exposure. The polythene wrapping alone is insufficient for this purpose. Avoid using solvent-based adhesives containing methyl ethyl ketone.
