Garage roof insulation between rafters.

If your attic is going to be converted into livable space then you will need to insulate the roof rafters. Install ventilation baffles into the space between the rafters before you install the insulation usually by stapling into place. In a warm roof structure the insulation is placed above or above and between rafters in order to avoid heat loss and energy transfer.

Garages built without attics are also prime candidates for insulation. In the case of a cold roof structure the insulation is placed between or between and under the rafters or at ceiling joist level and the roof is ventilated by leaving a 50mm gap above the insulation which vents air to the outside. This allows you to put insulation on the bottom side of the rafters but allows outside temperature air to circulate under the roof continued michael karas feb 20 16 at 23 18. Apply insulation between rafters when finishing an attic into a heated room or when building a cathedral ceiling in the home.

Don t insulate your garage walls and ceiling without insulating the big garage door too. If a ventilated roof is being constructed there is a requirement to have a 50 mm fully ventilated air gap between the insulation and the sarking felt in order to avoid condensation.
