Aerogel Insulation System for Solid Walls
Aerogel insulation boards offer exceptional thermal performance in an ultra-thin, breathable system for solid wall insulation, window reveals and hard-to-treat retrofit projects. Made with advanced aerogel technology, these boards help reduce heat loss where space is limited while remaining vapour open and fire resistant. With a Class A2 fire rating and minimal build-up depth, Warmshell Aerogel Boards are an ideal choice for heritage buildings, internal wall insulation and areas where conventional insulation would be too thick.
Aerogel Insulation System Components
- Warmshell Aerogel Boards for thin, high-performance internal wall insulation
- Silic8 Aerogel Adhesive for fixing boards to suitable mineral substrates
- Airtightness tape, such as Contiga Solido-SL, for sealing junctions and improving airtightness
- Solo Onecoat Lime Plaster for a breathable lime plaster finish
Benefits of Aerogel Insulation
- Superior Thermal properties
- Ultra-thin insulation depth, ideal where internal space is limited
- Vapour open and breathable, supporting moisture movement in solid wall construction
- Class A2 fire rating for added peace of mind
- Easy to cut and fit around reveals, heads and awkward details
Why Use Aerogel Around Window Reveals?
Installing 10mm aerogel insulation to window reveals and heads can make a significant difference to energy performance when fitted correctly. These areas are common thermal bridges, so a thin layer of aerogel can help reduce heat loss, improve comfort and support a more complete solid wall insulation upgrade.
Installing Aerogel Insulation Boards
Silic8 Aerogel Adhesive
Silic8 Aerogel Adhesive is a water-based mineral adhesive and primer designed for use with aerogel insulation boards. It is used to bond Warmshell Aerogel Boards to suitable solid mineral surfaces and can also be applied as a primer over the boards before finishing with Lime Green Solo Onecoat Lime Plaster.
Mechanical Fixings for Aerogel Boards
In addition to adhesive, mechanical fixings are recommended in key situations to help secure the aerogel insulation system.
Use mechanical fixings when installing aerogel insulation above 2000mm.
Use mechanical fixings when installing aerogel insulation over large areas, including one full sheet or larger.
Finishing Coat for Aerogel Insulation
The recommended finish for the aerogel insulation system is a coat of Aerogel Adhesive as a primer followed by 2 passes of the Solo Onecoat Lime Plaster with an embedded mesh in the first pass.
