In an uninsulated home a quarter of your heat is lost through the roof. Insulating your loft is an effective way to reduce your heating bills. Warmwall are leading Loft Insulation Installers in the South and offer the following advice:
It’s never been more important to think about insulating your loft. Without proper insulation a lot of the valuable, expensive energy you use to heat your home will be lost. The recommended depth for mineral wool insulation is 270mm, however there are other materials that require different depths.
Loft insulation is an effective way to save energy and money at home. A well insulated house keeps warmth exactly where you need it – indoors.
So, insulating your loft – or topping up any insulation you already have – will help to heat your home more efficiently. Using less energy reduces carbon dioxide emissions (CO2): one of the biggest causes of climate change. You will also save money on your utility bills too.
How does loft insulation work?
Heat will always flow from a warm area to a cold one. The colder it is outside, the faster heat from your home will escape into the surrounding air.
Insulation makes it much more difficult for heat to pass up though your roof by providing a layer of material which has lots of air pockets in it. These pockets trap heat, cutting what is known as the U value of the loft.
The U value measures how quickly it loses heat so the lower the U value, the less energy you need to keep your home warm. Loft insulation cuts your U value from around 2.3 (for an un-insulated loft) to 0.16 W/m2K, a reduction of around 95%.
You may on occasions also see references to an R value. An R value is a measure of thermal resistance and is the inverse of a U value so the higher the R value the better. The NIA recommend lofts should be insulated to an R value of between 6.1 and 7 Km2/W. The R value is usually displayed on the packaging of insulation. R values can be added together to reach the total required.
Loft insulation is effective for at least 40 years, and it will pay for itself over and over again in that time. The better insulated your home, the less energy you need to keep it warm – the more money you’ll save in the long run.
By saving energy, your household will produce less CO2. So, adding or topping up your insulation is a great way to do your bit – and reduce your impact on the environment.
If everyone in the UK installed 270mm loft insulation, we could save around £520 million and nearly three million tonnes of CO2.
