Polystyrene Insulation

At Collier & Catchpole, we supply a selection of polystyrene insulation products chosen for their thermal properties, durability and ease of installation, trusted by builders, contractors and DIYers across Colchester, Ipswich, Lawford & the surrounding areas.

Our polystyrene insulation category includes expanded and extruded board options suitable for cavity wall ties, loft floors, underfloor insulation and external cladding systems.
