How to insulate your Home - Roof and Lofts
Insulating your roof, loft or attic can be a simple and effective way to keep your home warm and reduce your energy bills.
Heat rises and in an un-insulated home, a third of heat can be lost through the roof. Insulating your roof, loft or attic can be a simple and effective way to keep your home warm and reduce your energy bills.
Installing loft insulation should be easy if there’s no damp areas or condensation. Insulation needs to be laid in two steps; the first layer should be laid between the joists and the second layer should be laid in right angles to cover the joists and increase the insulation to meet the correct depth. You can do this yourself or hire a professional if you prefer.
Using your loft for storage or living space
You’ll need to cover the insulation and joists with insulation boards and then overlay these with wooden boards. Pre-bonded insulation boards are available to save time and make the job easier. An alternative would be to raise the floor level so you can add the insulation underneath, whichever option you choose it’s important to ensure you don’t squash the insulation as this will decrease its effectiveness.
You can choose to use your loft as a living space, insulating the walls and ceilings and using high performance windows to help keep in warmth. You'll need to speak to a professional to find out about correct insulation as there are many, like cold roof and warm roof insulation, depending on your roof type and also ensuring that there's suitable ventilation for the space.
Damp loft or attic?
Your loft or attic can be cooler due to lack of heat from insulated rooms, which could create damp areas or worsen existing problems. If you decide to insulate your home yourself, speak to a professional first as they may be able to make suggestions on fixing the damp areas before the insulation process begins.
