External Wall Insulation warms your home and saves you money

What is External Wall Insulation?

External wall insulation involves fixing a layer of insulation material to the external walls of your property. This is then covered with reinforcement and a special type of render.

The final process utilises a wide choice of textured finishes, brick slips or brick effect render to transform the look of your property. However, the real benefits are how warm your home will feel, and how much money you will save on your energy bills! Westville’s work completely transformed a weather worn two storey cottage in Nottinghamshire to a stunning, energy-efficient home.

Why should I get External Wall Insulation?

Is the outside of your home looking somewhat neglected, tired and in need of a little renovation? Does it feel cold in the winter or suffer from damp, mould or mildew? Would you like to save around £460 a year on your utility bills? If the answer is “YES”, then you really should be considering our 25-year guaranteed External Wall Insulation, which solves all three in one simple solution!

Insulating your external has many benefits, including lowering heating bills by reducing heat loss through walls. Helping to prevent damp & mould. Using less fossil fuels, reducing carbon emissions. Raising the temperature of internal walls, reducing condensation. Increasing the thermal efficiency of walls by 85%. Westville’s work in Bilborough involved carrying out the full strip of a BISF house followed by installing full external wall insulation that brought this home back to life and made a huge difference on its thermal performance.
