External Wall Insulation
External Wall Insulation is the most efficient way to insulate an existing building - fact. It wraps up buildings external walls and uses them as thermal mass, just like storage heaters.
Walls accumulate the heat and prevent temperature fluctuations, keeping constant and comfortable environment.
External Wall Insulation can help reduce your heating bill by up to 50%. It can also reduce your carbon footprint by cutting your CO2 emissions by up to 2.5 tonnes per year.
Reduce Your Heating Bills With External Wall Insulation
You can achieve a reduced heat lose of up to 60% and conversely your heating bill can be reduced by a similar amount by installing external wall insulation. In short External Wall Insulation is a modern method of construction that will:
Insulate the building.
Eliminate Condensation.
Help reduce external noises
Stabilise the structure.
Provide a decorative low maintenance finish.
Provide a highly economical solution.
How Is External Wall Insulation (EWI) Applied?
Step 1: The insulation is mechanically and adhesively fixed to all external walls. This creates an insulation envelope that prevents heat loss and cold cold bridging, which can occur if using other types of insulation E.G. cavity fill.
Step 2: An impact resistant open weave mesh is embedded onto the insulation board using a base cement coat. This provides both impact resistance and tensile strength.
Step 3: A coloured primer is applied to the base coat when fully dry (Approximately 24 hrs). This aids adhesion, water resistance and will help in the colour uniformity of the finish coating.
Step 4: A coloured and textured acrylic render is then applied, the final result is a durable low maintenance finish that will only need to be hosed down to clean every 3 - 5 years. (As the finish has a 1% fade rate in a 10 year period.)
