Insulating your solid walls could cut your heating costs considerably, because solid walls let through twice as much heat as cavity walls do.
Homes built before 1919 likely feature solid rather than cavity walls. Cavity walls are made of two layers with a small gap or ‘cavity’ between them. Solid walls have no gap, so they let more heat through.
With our complete approach to external wall insulation render systems, we're committed to improving the external appearance, thermal efficiency and environmental performance of buildings throughout Brighton and Hove, plus the surrounding areas across Sussex.
We deliver both long-lasting advanced just-render as well as full external wall insulation systems. Both are British Board of Agrément (BBA) approved and the versatile selection of solutions are suitable for the entire Brighton and Hove building stock.
The silicone render range combines silicone and thin coat render technology to provide a flexible, breathable and durable system that will last.
Approved professionals with extensive technical expertise and support throughout the entire installation process ensure every project is completed to an exceptional standard.
We use BBA approved products, a validation that we select the best materials to make up our just-render and external wall insulation systems, allowing us to provide a 25-year warranty on our work.
The systems are available in 1000s of finishes, and provide the following benefits to properties –
Support services include regular audits of the site by external wall insulation render system providers, with technical guidance to ensure projects are being delivered to the best possible standards.
We provide advanced thermal resistance (U-value) calculations, pull-out tests, wind load calculations, condensation risk analyses and other technical guidance specific to the project.
We include all warranty and certification requirements including IAA, SWIGA, BBA and NSAI. This offers peace of mind on completion of the project.
1 -Substrate preparation - refers to priming the surface of the substrate before commencing any work in the installation process.
2 - Starter track and clip-on profile - a starter track is a UPVC or aluminium base that is applied above the DPC to provide a level surface for the insulation. Aluminium starter tracks require clip-on profiles to create a need finish.
3 - Adhesive - is used to create a reinforcement layer or to fix insulation boards to a substrate for an EPS system.
4 - EPS insulation - is a high-performing cost-effective insulation material used to upgrade the thermal properties of a building.
5 - Mechanical fixings - are small fixings used to secure the insulation to the substrate.
6 - Base coat - is used to provide a strong surface on which to apply render.
7 - Fibreglass mesh - is intended to be embedded within the base coat adhesive to enhance the tensile strength and crack resistance of the overall system.
8 - Render primers - are used to aid the adhesion between the renderer and the base coat, and also to limit the absorptivity of the basecoat layer, ensuring the renderer cures properly.
9 - Decorative finish - available in 1000s of colours. They provide a long-lasting crack-proof, aesthetically pleasing facade.
Exterior external wall insulation adds a new weatherproof layer to the building, as well as slowing the movement of heat through the walls. Another advantage is that external wall insulation will cause the temperature of the walls themselves to rise. This means if there is lots of water vapour in the air (from cooking, washing, or drying clothes inside the building), this will no longer condense on the freshly insulated walls.
