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 £115 to £415 every year* on household bills.

If you’re not sure how or when your home was constructed, we can find out at your no-obligation home assessment.  As a quick guide, if your home was built pre-1920s it’s likely to be of solid wall construction.

External installation

Installing Solid Wall insulation gives a property a complete facelift. Your home becomes more warm and welcoming on the inside, and benefits from a fresh and attractive makeover on the outside too.

Installation is professionally planned and takes place outside your property. Our Solid Wall insulation is a system made up of rail frame, insulation boards and weather-proof render. We offer a variety of 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.

The walls are insulated from outside temperatures, and the exterior of your home gets a facelift.
