A Guide to Insulating Your Home

If you’re looking for ways to insulate your home and save money on the heating bill while keeping warm, insulating your home is the easiest way to cut down on the need to put the heating on and, therefore, cut down on expenditure. There are many different ways to insulate your home, including:

Wall Insulation

The first thing you should consider is insulating the walls. A lot of the heat lost from your home is lost through the walls, roughly a third of all heat loss. Assuming that you house was built after the 1920s, it’s likely your house has cavity walls. These are walls that have an empty space between two layers of bricks. There are a variety of ways to insulate your walls such as, blanket insulation, foam board insulation, concrete block insulation, loose fill insulation and liquid foam insulation. Different types of insulation have different R-values (thermal resistance values) and are priced differently. Polyisocyanurate foam board insulation one of the highest R-values, roughly between R-7.0 and R-8.0 per inch of thickness, while loose fill insulation has one of the lowest R-values, between R-2.2 and R-3.8 per inch of thickness.

Loft Insulation

Insulating your loft is the easiest way to reduce the loss of heat from your house. Over 1/10th of the heat lost from your house is lost through the roof and adding insulation to the loft can drastically reduce the amount of heat lost. Insulating your loft is relatively cheap and is relatively easy to do and can usually be done as a DIY job, just make sure you use protective clothing as insulation can cause skin irritation.The most common way to insulate the loft is blanket insulation. Blanket insulation is usually made out of fibreglass and generally has an R-value between R-2.9 and R-4.3 per inch of thickness.If you have less than 10” of loft insulation, it’s recommended that you add more insulation until it’s at least 10” thick. When insulating your loft, you need to think about ventilation. Always leave a space around the eaves to make sure that the loft is properly ventilated.

Floor Insulation

Around a third of all heat lost is lost through the floor. Under floor insulation can be expensive due to needing to lift the floorboards. Installing under floor heating is best left to a licensed professional but it is possible to carry out the installation yourself. Like with insulating the loft, blanket insulation is the best option for installing floor insulation and like with loft insulation, you need to make sure that the area under the floor is still well ventilated to avoid causing rot. Another way to help insulate the floor is to buy thick carpets and rugs and insulated carpet underlay, which can be picked up fairly cheaply.

Other ways to reduce heat loss

Other ways to insulate your home is to buy draught excluders. They’re cheap and can be bought in a plethora of colours and styles. Also, something as simple as keeping your doors closed will help to keep the heat in the respective rooms.
