Services
Silicone Renders
Our silicone renders provide flexible, breathable finishes for external walls. These hydrophobic coatings resist water penetration while allowing vapour transmission, preventing damp issues. Ideal for both modern and traditional buildings, they offer long-term protection against weathering and pollution with minimal maintenance requirements.
Monocouche Renders
Monocouche renders deliver durable, through-colour finishes in a single application. Designed for speed of installation, these cement-based renders combine weather resistance with aesthetic versatility. Suitable for new builds and refurbishments, they eliminate the need for painting cycles while maintaining breathability.
External Wall Insulation
Our EWI systems improve energy efficiency through advanced insulation boards and reinforcing basecoats. These complete systems reduce heat loss while enhancing faade durability. Compatible with various substrates, they meet modern thermal performance standards for both residential and commercial properties.
Lime Render Range
The lime render collection offers breathable solutions for heritage and eco-friendly builds. These flexible renders accommodate structural movement while managing moisture. Suitable for both internal and external applications, they maintain compatibility with historic building methods and materials.
Brick Slips
Brick slips provide authentic masonry aesthetics with lightweight installation benefits. Available in multiple finishes, these cladding solutions suit both new constructions and faade renovations. When combined with appropriate adhesives, they deliver durable, weather-resistant exteriors with minimal structural impact.

The range of tools, mechanical tools and spraying machines in their stores for all rendering purposes is excellent. I recently bought a hot wire cutter, which is a really good tool to use. It allows my team of installers to get a nice cut on all the polystyrene boards making it easy for them to do the basecoats and topcoats. The spray machine I currently use is almost knackered so I plan to utilise some of EWI Store's discounts to get my new one, of which they have a fantastic range.

I am really pleased with the service EWIstore provided, very kind and good manners. And what to say about the delivery, ordered it lunch time and day and a half later I had all I need at the front door, really quick and good service. Highly recommended to anyone.
