External Wall Insulation

We supply complete external wall insulation render systems designed to improve thermal performance and protect buildings from the elements. Our systems include insulation boards, basecoats, reinforcement mesh and decorative topcoats suitable for use with K Rend and Parex render systems. Products can be delivered direct to site, usually within 48 hours, including EPS and Phenolic insulation in all sizes, fixings, beads, baserails and trims.

These thermal rendering systems combine high-performance insulation with durable render finishes to create energy-efficient, weather-resistant facades suitable for residential and commercial applications.
