The amazing advantages of external wall insulation!

10 Jan

Welcome to the first blog of 2014. Today I decided to go back to basics and talk about one of Eco People’s main business activities, the installation of external wall insulation (EWI). Over the past few years we have seen an increase in interest regarding EWI, so today I will be giving you the many different advantages.

Houses have two different types of walls; solid and cavity walls. If your home was built after the 1920s, it’s probable that you’ll have the latter – where two walls are separated by a small gap (a cavity) which acts as a heat barrier. Solid walls are less efficient at holding heat, often permitting around twice as much heat to pass through them. Not only does it improve the appearance of external walls, it also ensures a uniform thermal performance without any cold bridging. The concluding result will consist of a cosy, draught free house with reduced heating prices.

So this brings us onto the first advantage: A decrease of heat loss in cold weather and heat gain in warm weather. By reducing heat loss through the fabric of your building, you will improve energy efficiency which will in turn give you a much warmer building allowing you to be less dependent on your heating system. This will help you save money on your heating bills as around 35% of a house’s heat is lost through its walls – A total waste of money!

The second advantage is combating with damp. Now if you have damp in your home you will agree that it can be a nightmare! EWI can lessen condensation on internal walls as the new cladding protects the wall from further dampening. By reducing the condensation in your home this will improve your comfort levels.

A further advantage is the benefit of an external makeover. The external appearance of your home can be greatly improved using the range of coloured renders, brick effect and other specialist finishes available. Older homes are often significantly improved to the high standard of new builds. This benefit has its own benefit in that if your building is more attractive, potential buyers will find it more attractive, particularly if it’s a cheaper building to heat.

Do you live on a busy road? Noisy neighbours? Well this one is for you. EWI can improve the acoustics of your home. The high-density insulation used in External Wall Insulation reduces sound-transfer. This means less noise enters your home, giving you a more comfortable environment. Alternatively, you could be happy that less noise escapes!!

By installing external wall insulation you can also help the environment by burning less fossil fuel. By implementing external wall insulation, you are refining the thermal properties of the building and decreasing the heat required to warm it. You are therefore reducing the burning of fossil fuels, and helping the environment.

Not only do Eco People install EWI on homes, we also install the insulation of various types of businesses. On average you will spend half your week in the workplace so why wouldn’t you want a warm, damp free and pretty environment!

    The difference in pictures is incredible. Like cavity wall insulation damp, would you say things could go wrong with external insulation?
