External Wall Insulation

We supply complete thermal rendering systems and external wall insulation products designed to improve energy efficiency while protecting buildings from the elements. Our systems include insulation boards, basecoats, reinforcement mesh and decorative topcoats compatible with K Rend and Parex render systems. Products can be delivered direct to site, usually within 48 hours, including EPS and phenolic insulation, fixings, beads, baserails and trims.

Our thermal rendering systems combine high-performance insulation with durable render finishes to create energy-efficient, weather-resistant façades for residential and commercial projects.
