Summary: Learn how to insulate the rafters.
There two main reasons for insulating the roof: to save heat energy and when converting the attic into an additional room.
When insulating between the rafters in the attic, firstly ensure there isn't a leak in the roof. Check it out to avoid complications at a later date. This is especially important, as leaks are hard to spot after insulation has been installed.
There are two types of insulating material designed for this job: blanket insulation and semi-rigid fibre insulation batts.
Another factor to consider is condensation caused by the underside of the tiles becoming very cold. This problem can be overcome by providing adequate ventilation.
Fix lengths of treated timber to the inside edges of each rafter to create a ventilation space.
Fit the insulation material between the battens.
Create a vapour barrier by stapling polythene sheeting to the rafters over the blanket.
If required, a solid finish can be achieved by covering the rafters with sheets of plasterboard.
