Description
BEWI external wall insulation (EWI) is manufactured from expanded polystyrene (EPS) and can be bonded and/ or mechanically fixed to an external wall.
BEWI EWI is supplied as EPS 70E and EPS HP+70 E (grey) as defined in BS EN 13163. It contains a flame retardant additive to achieve Reaction to Fire Class E. BEWI EWI for use with a rendered finish should be “aged” material.
BEWI Basetherm, (specified separately), can be used as an accessory product to insulate the plinth below the damp-proof course and provide an impact-proof base
board.
Features and benefits:
- Available in a range of Lambda values.
- 100% recyclable.
- Off-cut collection.
- Achieves an A+ rating in the BRE Green Guide to Specification.
- Lightweight and easy to handle.
- Flood resilient and durable.
- Can be cut to fit with a sharp knife.
- Helps to achieve a high-quality rendered surface.
- Insulates for the lifetime of the building.
- Reaction to Fire Class E.
