Quality Rendering Options. Established. Proven. Guaranteed.

The finish (Render) of your external wall insulation is both cosmetic and an additional insulation for additional energy savings.  A Render is a basecoat on which a variety of other finishes or finishing coats may be applied.

Insuloptim work with only leading manufacturers of quality renders providing finishes suitable for contemporary new build or refurbishment projects. Many of the renders and finishes are also an integral feature of our External Wall Insulation (EWI) systems, and are also available as a render only option for new build applications. There are five types of render systems that we provide:
