What is External Wall Insulation

What is External Wall Insulation (EWI)?

 

If your house was built prior to the 1930s, the chances are that it will have solid walls. Insulating your solid walls  is a great way to make your home more energy efficient. The insulation will minimise heat loss in the winter, saving you money on your heating bills. It will also stop your home getting too warm in the summer, helping to keep your home at a more comfortable temperature.

According to research, twice as much heat could be lost through an un-insulated solid wall as through an un-insulated cavity wall. However, the great news is that solid walls can be insulated, both internally and externally.

How is EWI applied

For external wall insulation, you need to employ a professional.  The home can be insulated using an adhesive material which is fixed to the wall, then plastered over.  The finish applied to the external wall can be any combination of texturing, painting, tiling, brick slips, masonry work and/or cladding. A survey of your property will be carried out by RamEco prior to installation to ensure the product will work to its full potential and comply with all regulations.

Planning permission and Building Control

As fully accredited professional installers of EWI, RamEco can self certify the insulation works which is required by law. Building regulations must be adhered to and in some instances Planning Permission. This is because this process involves covering the original brickwork and could significantly alter the current appearance of the property, impacting the character of the local area. Once any planning permission has been granted, the home can be insulated. RamEco will carry out all the checks for you so you can have peace of mind that your product not only complies with Building Regulations but also has full permission.
