External Wall Insulation Systems

External Wall Insulation (EWI) is an extremely effective method of insulating buildings. The systems are based on a simple premise…insulation is more cost effective when placed on the exterior of a building. EWI comprises a continuous layer of insulation that is fixed adhesively and/or mechanically to the outside of a building. The insulation is then coated with a decorative weatherproof render which can be finished in a wide array of textures and colours allowing you freedom to create the desired aesthetics for your building. By bringing insulation to the outside of external walls it eliminates thermal bridges; reduce air, wind and moisture penetration through the systems; stabilise interior environments and minimise thermal shock. Refer to System Sheets for a guide to each system build-up see below.

+Barrier Systems
Outsulation®

EWI and finish system incorporating expanded polystyrene (EPS) insulation. Directly adhered to the substrate with a polymer modified adhesive, or with the addition of mechanical fixings depending on substrate conditions. Suitable for use over solid or framed substrates.

Drysulation

Cost Effective EWI and finish system incorporating standard grade expanded polystyrene (EPS) or high performance low lambda EPS insulation. Directly adhered to the substrate with a polymer modified adhesive, or with the addition of mechanical fixings depending on substrate conditions. Suitable for use over solid or framed substrates.

+Moisture Drainage Systems
Outsulation® Plus

EWI and finish system incorporating expanded polystyrene (EPS) insulation and an air and moisture protective barrier. Directly adhered to the substrate with a polymer modified adhesive, or with the addition of mechanical fixings depending on substrate conditions. Suitable for use over solid or framed substrates.

Outsulation® Rail

EWI and finish system incorporating expanded polystyrene (EPS) insulation fixed on mechanically fixed rails on shims to level substrates and/or provide a cavity for incidental moisture drainage. Suitable for use over solid or framed substrates.
