What is it?
An uninsulated loft can be responsible for a quarter of a home’s heat loss. To help reduce the amount of heat escaping your home, you can add insulation to your roof or loft. There are two ways to do this.
Cold loft
Insulating for a cold loft means putting insulation between the joists that separate your loft from the rest of your house. You can do this yourself by buying rolls of mineral wool insulation or insulation boards and fitting it between the joists. Insulating at the joists keeps your house warmer but makes the space above colder. The benefits of insulating at the joists are:
- It’s cheaper than insulating at the rafters
- You can save money by doing it yourself
- It will cost less to heat your home
Warm loft
Insulating for a warm loft means putting rigid insulation between the rafters that make up the roof of your loft. This will require a professional installer. Insulating at the rafters will be a better choice if you plan to use your loft or if there are any pipes or tanks in your loft, as these could freeze if you insulate at the joists. However, insulating at the rafters is less efficient as it means you have more space in your home to heat. The benefits of insulating at the rafters are:
- Prevent pipes and tanks from freezing
- Loft is still usable
What are the benefits?
Insulating roofs and lofts of your property means less heat can escape, lowering the cost of heating
Using less energy to heat your property means less CO₂ is released into the atmosphere, reducing your impact on climate change
Increasing the energy efficiency of your property increases the value of the property and makes it more appealing to buyers and renters
A well-insulated property will be easier to heat to a comfortable temperature. It will also help keep the property cooler in summer
