Phenolic Insulation

Glass faced phenolic insulation was chosen for its ease of bonding, low conductivity of 0.021 W/m.K, good compressive strength and resistance to the passage of water vapour.

In a fire, it combines very low flame spread with negligible smoke emission and a very low level of toxic gas emission.

Bonded to wall plaster with Gripfill. Other walls have been bonded with Mapei Keraflex and polyurethane adhesive for comparison.
