Its a surprise to many that roughly 35% of all heat loss in a home occurs through the walls. This loss generally occurs through conduction or physical contact since a home’s walls are in physical contact with the colder temperatures outside.
External wall insulation (EWI for short) is a system comprising high performance layers which are fitted to the external walls of your home to insulate, decorate and protect it.
It includes a specialist render cladding of your choice. With a wide range of finishes in a variety of colours and textures, we can give your home a durable and attractive appearance.
EWI is particularly suited to solid wall homes; however we can also provide advice on non-traditional construction properties.
What does it involve?
Often requiring scaffolding, the installation of external wall insulation typically takes a week to complete depending on the weather and the size of your home.
Insulating material is added to the outside walls of your home and is then coated with a protective render or cladding. This is a specialist job and requires an approved installer who can specialise in the use of our insulation system.
We can help you locate an approved installer specific to your area. Call us on 01535 661 633 or drop us an email for more information on info@spsenvirowall.co.uk
Key Benefits of External Wall Insulation
Reduce Heat Loss
The extra thick layer of insulation will help to trap heat inside your home and reduce cold air penetration, thereby improving the energy efficiency of your home, by up to 33%!
Save Money
Homeowners of a standard 3 bed property with External Wall Insulation can expect to save £ hundreds per annum on their energy bills!
Easy to install
Although more labour-intensive than cavity wall insulation, installing External wall insulation can be achieved in less than a week on a standard semi-detached/detached property.
Reduce condensation and damp
Many properties suffer from condensation due to the natural moisture content within air. If this moisture is able to penetrate the buildings exterior it can turn into damp and mould, which is not only unsightly but can cause structural issues and be expensive to remedy. Installing External wall insulation increases the internal temperature of you property, eliminating condensation and therefore damp.
Reduce environmental impact
Most properties use gas, oil or LPG for heating, and burning these fossil fuels produces carbon dioxide and therefore CO2 emissions. Installing External wall insulation reduces the need to use so much heat, reducing your CO2 emissions
Improve appearance
The exterior of a building is exposed to the elements and naturally suffers from stains and wear and tear. External wall insulation provides your home with a brand new finish, requiring little maintenance and adding value to your property
