Description
BEWI Substructure Insulation Boards are manufactured from closed-cell expanded polystyrene (EPS) with low water absorption.
The insulation is a lightweight and easy to install solution. There are no requirements for special PPE when installing or cutting the insulation panels.
Features and benefits:
- Thermal conductivity as low as 0.031 W/m·K.
- Resistant to the effects of freeze/ thaw.
- High compressive strengths available 200 and 300 grade and 200 +.
- Global warming potential <5, ozone depletion potential = Zero.
- Excellent compressive strength.
- Resistant to ground moisture penetration.
- Unaffected by air infiltration.
- Easy to handle and install.
