Roof and loft insulation

What is it?

An uninsulated loft can be responsible for a quarter of a homes heat loss. To help reduce the amount of heat escaping your home, you can add insulation to your roof or left. 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 joist. 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 to fit the installer. Insulating at the rafters would 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 useable
