Internal Wall Insulation

What is Internal Wall Insulation?

Internal wall insulation involves fitting high-performance insulation boards or thermal linings to the inside of external walls, reducing heat loss through solid walls that lack a cavity. This solution is perfect for older homes or properties where external wall insulation isn’t suitable or permitted, as it keeps the building’s exterior unchanged while dramatically improving thermal performance.
