Renders & External Wall Insulation Systems

Professional renders and external wall insulation supplies for contractors, builders, and self‑builders. Moreover, at Renders World we stock premium insulation boards, silicone render systems, reinforcement mesh, and EWI adhesives and basecoats for all rendering and insulation projects across the UK.

Premium Render Systems & Finishes

Our comprehensive range of renders includes silicone thin‑coat systems in over 1000 colours, acrylic renders, mosaic finishes, and specialist decorative coatings. In addition, these external render solutions offer superior weather protection, high breathability, and long‑lasting aesthetic appeal for every property type. Consequently, all systems integrate cleanly with leading EWI systems (adhesives & basecoats) for seamless installation.

Complete External Wall Insulation Solutions

We supply a full selection of external wall insulation materials, including reinforcement mesh, base coats and adhesives, finishing renders and insulation boards. For example, whether you are installing solid wall insulation on period properties or modern EWI systems on new builds, we deliver quality materials from Atlas and Ceresit as their official UK distributor. Therefore, you can specify confidently and achieve consistent results.

In addition, our insulation boards range covers EPS and XPS boards for robust, moisture‑resistant EWI specifications.

Quality & Durability You Can Trust

Our renders and external wall insulation systems are engineered for UK weather. Notably, pairing reinforced mesh with the right basecoat improves impact resistance, while priming ensures an even, durable topcoat. Meanwhile, you can explore wall primers to optimise adhesion and colour uniformity before finishing.
