Energy Saving Tips
are still 6.3 million homes which need cavity wall insulation. Cavity wall insulation pays for itself in around two years, and it will typically save 15 per cent – or £115 – a year on your home’s fuel bills. Cavity wall insulation needs to be installed by a professional and can be finished in a single day. The cost of having cavity wall insulation installed has never been lower as it’s subsidised by the Government which has pledged to slash the UK’s greenhouse gas emissions by 80 per cent by 2050.

solid walls. External wall insulation can save a whopping £400 a year on energy bills, cutting down heat loss through the walls by 35%. This means that although it requires a significant investment to install, it begins to pay for itself immediately with huge money savings and these will continue forever.
internal wall insulation can save around £380 a year on energy bills and an impressive two tonnes of carbon dioxide annually.
the floor ensuring that a home has an adequately insulated floor can provide additional energy savings. Significant savings can be made by reducing draughts by sealing gaps around loose floorboards and skirtings. However, it is sometimes possible to insulate

timber floors by lifting the floorboards and laying glass mineral wool insulation supported on netting between the joists.
With 2009 being the coldest for 20 years it is important to ensure that your new build / renovation is fully insulated. Creating an air tight home is essential in providing a build which is not only warm but energy efficient.

single year from when it’s installed. Not only is installing loft insulation a pretty straightforward job, but it will boost your homes energy efficiency rating too. Even if you’ve already installed loft insulation by topping it up to 270mm you could save on average an additional £45 year on year.
Types of Insulation: - Glass Mineral Wool Probably the world's most popular and widely used insulation material, glass wool is made from recycled glass bottles so it is ultra-eco-friendly. It is easy to handle and install plus it is an extremely a cost-effective insulation. Glass mineral wool is rot-proof, odourless, non hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria. It is chemically neutral and does not contain impurities.
structure, so is ideal for situations where it may be under compression (e.g. on a flat roof). Mineral wool insulation products are available in rolls of different widths and thicknesses for quick and simple DIY installation - for example,

between the rafters in a roof or joists in a ceiling or floor. It can also be produced as lightweight ‘slabs’ for installing into the cavity walls when building new houses. ‘Loose’ mineral wool can also be used to fill cavity walls and is blown in through a hole drilled in the wall after it is built. Installing mineral wool insulation is also an effective fire safety measure as it does not burn easily and can therefore prevent fire spreading. In fact, rock wool can resist temperatures above 1,000°C.
strength and is usually used where it needs to support weight (e.g. under a floor, or in lofts as a storage solution). As well as strength and durability, rigid foam insulation can also provide additional properties such as fire resistance and acoustic insulation to minimise the level of sound travelling through walls and floors. Lydia Sharples from
Thinkinsulation.com,
says: “There are so many simple ways in which households can become more energy efficient and save money as an added bonus; the payback on loft insulation can be as little as two years. As one third of all heat escapes through the walls of a house it's also worth investigating cavity or solid wall insulation, particularly as there are many grants available at the moment.”
