Is External Wall Insulation a Smart Investment?

Investing in External Wall Insulation (EWI) is a smart choice for homeowners facing significant heat loss. It is believed up to 35% heat lost is through uninsulated walls, which results in colder rooms and higher heating costs. Many homeowners attempt to alleviate this issue by putting the heating up, leading to substantial energy bills.

Solid walls without cavities exacerbate the problem by causing condensation when warm air meets cold surfaces, eventually leading to mould and damp issues.

Our external solid wall insulation effectively addresses these challenges by creating a robust thermal barrier. By insulating your home's external walls, you not only ensure consistent comfort throughout the year but also achieve substantial savings on heating and cooling expenses.

This investment not only enhances your home's appearance and increases its resale value but also contributes to a greener environment by reducing overall energy consumption and carbon emissions. Opting for External Wall Insulation represents a proactive step towards enhancing your home's comfort, value, and environmental impact, providing a comprehensive solution to insulation challenges.
