Polarwall ICF Bungalows

On 1 October 2026, Wetherby Wall Systems Limited will begin trading as ROCKWOOL Wall Systems. Our trading name is changing, but our people, products and services remain the same.

These modern high specification eco friendly bungalows were built using an insulated concrete formwork (ICF) building method.

This build process is up to 50% faster than traditional building methods, is a relatively low-skilled and flexible method of construction, requiring little in the way of plant and is recognised as a Modern Method of Construction by the BRE.

Once the structure had been assembled and the concrete poured into the recesses of the ICF blocks, to provide a structurally sound dwelling, a decorative Wetherby render system was selected to complete the final façade.

A K&A basecoat was applied to the outer ICF wall into which a strengthening alkali resistant mesh was bedded. A secondary layer of basecoat was applied to cover the mesh and provide a smooth base for the final topcoat.  Once the basecoat was dry a layer of Wetherby 1.5mm ‘K’ Silicone Render was applied to encapsulate the buildings and give a bright, modern, weatherproof finish to the properties.
