Installing Solid Wall insulation – the benefits 

Installing Solid Wall insulation (also called External Wall insulation) can transform the look and feel of your home while also dramatically reducing your heating bills.

A lot of heat is lost through ‘solid walls’, so installing Solid Wall insulation can make a huge difference to your home’s comfort and energy efficiency. As well as keeping in the warmth, InstaGroup’s highly effective system can save you between £105 to £350 every year* on household bills, depending on the size of your property.

If your home was built pre-1920s it’s likely to be of solid wall construction and could benefit from adding efficient insulation. We can find out more at your no-obligation home assessment.

Improves your home, inside and out

Installing Solid Wall insulation improves a property on the inside and the outside. Your home becomes warmer and more welcoming, with the added advantage of increased kerb appeal from a fresh and attractive external makeover.

Installation is professionally planned and takes place outside your property. Our Solid Wall insulation system is made up of robust rail frame and specialised insulation boards, and finished with an attractive weather-proof render. We offer a variety of render colours and finishes, so you can choose how to improve or add to the outside look and character of your property.

Installing Solid Wall insulation makes your home easier to keep warm in the winter, and keeps it pleasantly cooler in summer. You’ll find rooms are noticeably quieter too.
