What is loft insulation?

Loft insulation is usually glass fibre or renewable wood fibre material that creates a barrier in your roof space to prevent heat from escaping.

Insulation can either be laid between the joists of your loft floor or between the rafters that support the roof. The latter is typically more expensive and your choice will depend on whether you'd like to keep your loft space warm as well as your living space below.

Why is loft insulation a good idea?

Loft insulation is effective for at least 40 years and it should pay for itself many times over(2) by preventing heat escaping and cold air coming in.

We used to have our thermostat on 25 degrees most of the winter but now we only have it on 15 degrees, any higher and the property gets too warm. Also we are definitely saving money on bills.
