How loft insulation works

Loft insulation is quick and easy to install.

1
Insulation material
A survey is performed to determine the best insulation material. Mineral wool, cellulose and foam board are all excellent performers.
2
Installation
Insulation material is laid in between the rafters and the floor of the loft for maximum insulation.
3
Warmer in winter
Insulation creates a barrier to stop warm air from leaving through your roof space.
4
Cooler in summer
Insulation prevents excessive heat from entering through the roof in the summer months.
