Why Internal Wall Insulation is Important

Many older UK homes have solid walls that lose heat quickly, making them harder to keep warm and more expensive to heat. Internal wall insulation provides a simple yet effective way to improve your property’s thermal performance from the inside.

Improved Comfort and Lasting Energy Efficiency

Encap Installations fits high-performance internal insulation boards and thermal linings that form a warm, protective barrier inside your walls. These systems reduce heat loss, improve energy efficiency, and minimise condensation, creating a consistently comfortable home environment that performs better year-round.
