Benefits of EXTErnal wall Insulation (Ewi) Systems

Many older properties have external walls that are either unsuitable for cavity wall insulation (often because the cavity is too small) or have no cavity to insulate (solid walls). The so called "hard to treat" walls still require insulating to reduce heat loss, and Dorset Insulation provides the solution.


Buildings account for 40% of our energy consumption, in houses up to 45% of this energy is lost through the solid walls of the dwelling. Insulating solid walled homes has traditionally been considered expensive and ‘hard to treat’, but now there’s a perfect solution –Dorset Insulation's External Wall Insulation.
External Wall Insulation acts as a shell, protecting your property from the elements and helping to retain the warmth on the inside, while in warmer climates it can also help to maintain a cooler internal environment.  In addition to all this, it saves energy, reduces fuel bills and helps towards the reduction in carbon emissions, associated with the dwelling.

External Wall Insulation is part of the changing face of building methods within the UK, with the ability to not only deliver a thermally efficient, carbon saving façade, but also to visually improve buildings and at the same time extend the life and value of the building itself. With state of the art manufacturing technology, large range of finishes, suitability for most substrates and the knowledge that the system is manufactured by world leading companies in energy reduction, External Wall Insulation is turning insulation inside out.

Solid reasons to choose External Wall Insulation
External Wall Insulation from Dorset Insulation is a robust and versatile solution to an increasing demand for thermal protection, particularly in solid wall properties. The availability of both high-density rock mineral wool slabs and expanded polystyrene (EPS) ensures that EWI can be used in a wide range of applications. High quality silicone and mineral topcoat renders - designed to resist UV degradation and cracking - provide a superior finish to a superior system. New high performance self-maintaining paints, which can be used in conjunction with the system not only extends the life of a building, but also allows it to be brought to life with colour.
