Roof Insulation

Perfect for flat roofs, pitched roofs and sloping ceilings


We stock boards suitable for cavity walls, internal walls and between timber frames.

Our wall insulation is a fibre free rigid polyisocyanurate (PIR) foam core faced with an aluminium foil composite sheet on both sides.

The high performance boards keep thickness to a minimum without compromising on thermal performance, therefore optimising internal space.

These boards are available in the standard 2.4m x 1.2m (8ft x 4ft) size and in 1.2m x 1.2m squares. Thicknesses range from 25mm – 200mm.

Cavity wall batts measure 0.45m x 1.2m.
