By using the EWI and EPS Boards solid wall insulation system, we can bring the U-value of your home down to 0.3 W/m2k with just 100mm of insulation. This is equivalent to the U-value of a brand new house built to current building regulation standards.
Homes constructed prior to the year 1920 typically feature solid external walls devoid of a cavity, a characteristic that permits a substantial amount of heat to dissipate from the interior of your dwelling through the walls.
The implementation of External Wall Insulation (EWI) signifies a paramount improvement measure to your residence that significantly curtails heat loss. This insulation is strategically applied to the external face of the wall, serving as an effective barrier against heat transfer and thereby retaining a larger proportion of heat within your dwelling for extended durations.Ascertaining the type of wall your home possesses can generally be achieved through an examination of the brickwork on your home's exterior.
Solid wall construction is identifiable through the visible pattern displaying the long and short sides of bricks, akin to the illustration represented in Figure A.Conversely, homes featuring cavity walls exhibit brickwork where only the lengthier side of bricks is visible, as depicted in Figure B.
EWI is largely compatible with a wide array of property types, including those of non-traditional construction, with notable exceptions for listed buildings or properties situated within a conservation area. If these conditions pertain to your residence, it might be advisable to explore Internal Wall Insulation as a potential alternative.
Generally, the necessity for planning permission may be circumvented if the resultant aesthetic of the EWI closely matches that of the existing property exterior. However, definitive confirmation regarding this matter can be obtained from your local planning department.
The lifespan of external wall rendering and insulation depends on the quality of materials used, weather conditions, and maintenance. Generally, high-quality rendering and insulation can last for up to 25 years.
The amount of energy that can be saved through external wall insulation and rendering will depend on a variety of factors, such as the type of building, the size of the property, the climate in the area, and the quality of the installation. However, studies have shown that external wall insulation and rendering can reduce heat loss through the walls by up to 35%, which can result in significant energy savings over time. In fact, some studies have shown that homeowners can save up to 40% on their energy bills after installing external wall insulation and rendering. Additionally, these energy savings can lead to a reduction in carbon emissions, which is good for the environment.
External wall rendering involves applying a protective coating or render, to the exterior walls of a building. This can improve the appearance of the building, as well as protect it from weather damage.
External wall insulation is a method of insulating the exterior walls of a building to improve energy efficiency, reduce heat loss and improve the overall thermal performance of the property.
