Benefits of EWI with EWI Pro

02.10.2018

Benefits of EWI for your property…

 

1. Improve Thermal Comfort

Thermal comfort means that a property is kept at a comfortable temperature throughout all weather conditions. Whatever the weather, one of the benefits of EWI is that it can ensure that the inside of your property is the perfect temperature for feeling comfortable.

2. Cooler Summers, Warmer Winters

Building on the notion of thermal comfort, insulation not only ensures that your house stays warmer in the winter, but also protects it from gaining too much heat in the summer. EWI benefits the property by ensuring that heat generated by your central heating system remains within the building, while also stopping the cold air outside from entering the property. In the summer the reverse is true; the walls do not absorb the heat radiated by the sun, and therefore do not transfer it into the property. Wood Fibre insulation is a particularly high performance material for maintaining a cool indoor temperature in the summer.

3. Reduce Energy Bills

By ensuring that heat remains within your property, energy bills are dramatically reduced. A four bed detached house can expect to save approximately £455 a year on energy bills when installing 90mm of EPS onto a solid brick wall. External wall insulation pays for itself.

4. Improve External Aesthetics

Part of an EWI installation includes a render finish on top of the insulation boards to ensure the system is watertight. This is not only highly functional but also incredibly aesthetically appealing. EWI Pro renders come in a wide range of colours and textures for a unique and customisable finish that will stand the test of time.

5. Save Floor Space

One of the benefits of EWI is that it takes up no internal floor space; the entirety of the building is cocooned in insulation which is secured to the external walls with adhesive and mechanical fixings. Where UK property prices are at a premium and space is essential, the hassle of losing internal floor space is nonexistent and the entire installation process is quick and unintrusive (find an approved installer with EWI Pro for a quality install).  

6. Reduce Carbon Footprint

Your carbon footprint is dramatically reduced with external wall insulation because you use less gas and electric heating throughout the year due to your high levels of insulation, therefore households with EWI benefit from the fact that they are contributing towards helping the environment.

7. Increase Lifespan of Building Fabric

External wall insulation covers the entirety of the exterior of a property, wrapping it in a thermal blanket that not only prevents heat loss but also protects the building fabric against weathering. The external render that finishes the system benefits the property by acting as a weather-proof barrier, preventing water ingress and damage from extremes of weather.

8. Acoustic Insulation and Fire Resistance

EWI Pro Mineral Wool systems use Rockwool as the insulating material. Known for its acoustic insulating capabilities and fire resistance, EWI Pro Mineral Wool systems are a premium system, offering a broad range of unique benefits for the user.

9. Minimise Thermal Bridging

Thermal bridging occurs when there are gaps within an insulation system. These gaps are where heat loss is significantly higher, becoming concentrated to this area and allowing water and condensation to gather. Thermal bridging can significantly reduce the effectiveness of insulation, however with EWI thermal bridging is minimised due to the fact that the system is external and is completely seamless; there is no need for breaks within the insulation boards.

10. Reduce Damp and Condensation

Insulation slows the rate of heat transfer by retaining the heat within the walls; condensation occurs when hot air comes into contact with cold walls. Because the external walls of the property are warmer with EWI, condensation is vastly reduced, therefore helping improve indoor air quality and maintain structural integrity.
