Alongside with drastic reduction of heat loss, external wall insulation can also help with minimising draughts.

External Wall Insulation can take up to two weeks to complete.


External Wall Insulation is a solution for homes which were mostly built before 1920s. Along with helping to insulate your home, external wall insulation also helps to add a waterproof coating that acts like an extra protection.
