EXTERNAL WALL INSULATION
External wall insulation (EWI) does more than protect your home; it transforms it. We specialise in applying EWI to all types of solid wall properties, from cosy bungalows to large flat blocks. By reducing heat loss in winter and keeping your home cooler in summer, EWI cuts energy bills and creates a more comfortable living environment. As a Green Deal Approved Installer, we also offer a variety of custom finishes, including silicone, acrylic, and brick effect, ensuring your property not only performs efficiently but also looks fantastic. Contact us now, whether you’re a homeowner or part of a housing association; we provide solutions tailored to your needs.

WALL RENDERING SERVICES
We offer a versatile selection of finishes to suit your property’s style. Silicone and acrylic renders give a sleek, modern look with excellent durability, while scratch render adds a textured, rustic charm. For a more traditional feel, our brick effect render and brick slips replicate classic brickwork, and dry dash finishes with coloured aggregates can create a unique, eye-catching look. For a fully bespoke option, our Art Brick resin topcoat can mimic the colour and texture of traditional brick or stone.

SILICONE & ACRYLIC FINISH
A base coat render is applied at a minimum thickness of 8mm. This is ruled to provide a flat surface. A primer coat is then applied followed by an acrylic finish at 1-2mm.

SCRATCH RENDER
This product is applied over a base coat render at approximately 10mm thickness. The surface is then scratched back using a nail float resulting in a textured finish.

BRICK EFFECT RENDER
Two or three coat brick effects rendering, used to simulate the appearance of brickwork. A coloured mortar coat is trowel applied and the top coat is applied in a contrasting colour whilst still soft. This is then carefully set out and cut back using a specialist cutting tool.

DRY DASH FINISH
A coloured render coated with a spar dash finish. A wide range of aggregates in various colours can be used to dash the surface, which is applied at 8mm whilst the render is still soft.

BRICK SLIPS
Giving the traditional feel of a building, Brick Slips are produced by removing the face of existing bricks thus achieving genuine brick effect finish.

ART BRICK
ArtBrick can provide any colour and texture, with long-term durability in order to replicate the appearance of existing brick or stone facade.
PROTECTIVE AND STYLISH INSULATION
EWI works by adding a protective and insulating layer to the exterior of your property. This system combines insulation, secure fixings, and a finishing render or cladding that enhances both appearance and weatherproofing. We provide a wide range of finishes, from textured scratch render to traditional brick slips, so your home can look exactly how you want. Our approach minimises disruption to your daily life while delivering long-lasting results. Whether you prioritise cost or technical performance, our team uses the latest materials and techniques to ensure a flawless finish every time.

ENERGY EFFICIENT SOLUTIONS
External wall insulation offers a range of advantages for your property. It causes minimal disruption to occupants while significantly reducing heating costs, sometimes by as much as 40%. EWI also lowers maintenance needs by helping prevent condensation and mould growth. Beyond these practical benefits, it can increase the overall value of your property and extend the lifespan of the building, providing both long-term protection and improved comfort for homeowners.
