Energy Efficiency


When Eco-Rend is used on the outside of the building, studs do not break the continuity of the insulation. In essence, the building is covered by a blanket of insulation. This is an additional advantage over other types of cladding. Thermal breaks caused by studs provide an opportunity for energy to flow in and out of the building. Climate controlled air escapes and uncontrolled air invades the building, requiring the building’s HVAC system to work harder to maintain the desired air temperature and therefore costing more money to run and maintain.


When warm air meets a cold surface the result can be condensation. This is commonly seen on the outside of a glass filled with a cold drink. The location where the condensation occurs is called the dew point. While not an issue on adrinking glass, this same phenomenon becomes an issue when it occurs inside your wall construction. Traditional solid wall construction may lead to condensation forming on the inside wall or in cavity walls, within the cavity itself. This generally forms into mould, causing potential damage and deterioration of the building fabric. Using Eco-Rend will keep the building warm and significantly reduce the risk of condensation forming on the inside of a building or within the wall construction itself.


With External Insulation Systems, the wallsre main warm. Therefore, there is no risk of condensation within the wall or even where the wall makes contact with the insulation. This prevents the spalling of masonry and plaster, the corrosion of concrete rebar and potentially eliminates the need to carry out repairs after just a few years of the buildings life cycle.
