Description
BEWI Inverted Roof Insulation is a closed-cell expanded polystyrene (EPS) with low water absorption properties.
The insulation boards are loose-laid over the weatherproofing, there is no requirement to adhere or mechanically fix the boards. The BEWI Filter Membrane and selected build-up of the green roof to secure the insulation to the deck.
The system is a lightweight and easy-to-install solution. There are no requirements for special PPE when installing or cutting the insulation panels.
EPS is compatible with and can be laid directly onto hot melt and bitumen-based weathering membranes. See installation details for advice on other membrane types.
Features and benefits:
- KIWA certified (BAR-19-098-S-A-UK).
- Suitable for use on flat roofs with zero pitch and slopes up to 10°.
- Resistant to the effects of freeze/thaw.
- High compressive strengths available: 200 and 300 grade and 200 Premium+ to suit the green roof specification.
- Global warming potential <5.
- Ozone depletion potential = Zero.
