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.

Roxsulation®

EWI and finish system incorporating either mineral wool slab (Roxsulation S) or mineral wool lamella (Roxsulation L) insulation. 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.
