Insulating Attic Ceiling Rafters

Similarly a flat ceiling takes out the cathedral style slope of attic ceilings with joists that run parallel to the attic floor and are attached to roof rafters.

Insulating attic ceiling rafters.

If you have a solid floor covering the roof rafters use the claw end of a hammer to pull the floor up in several locations and blow the insulation under the boards. Additionally insulation serves as a way to enhance sound proofing on the uppermost envelop of your house. Install ventilation baffles into the space between the rafters before you install the insulation usually by stapling into place. Replace the floorboards and then spray more insulation on top of it.

Garages built without attics are also prime candidates for insulation. Fiberglass insulation is made from glass that has been heated and drawn out to form workable fibers. If you re considering turning your attic into conditioned storage or living space it s worth changing tactics to insulate between the rafters and wall joists instead of the floor. You can use rigid foam panels or do as tom silva does with nearly all houses these days.

Chemicals are then added to the insulation in order to provide fire resistance. In these designs take out attic. Insulating in and around your roof attic space also prevents long term damage from moisture build up or ice damming which results from the warm air trying to escape through the apex of the roof but instead heating up the snow. If your attic is going to be converted into livable space then you will need to insulate the roof rafters.

Apply insulation between rafters when finishing an attic into a heated room or when building a cathedral ceiling in the home.
