Adding Foam Board To Inside Of Truss Attic Space
Attic hatch or door.
Adding foam board to inside of truss attic space. Extra support for the trusses can be made by placing a 2 by 4 inch piece of lumber from each truss on one side to the truss on the other side high enough to provide head room but low enough to provide support for the trusses. Use a zippered insulated tent to keep the enclosure draft free attic tent at 7 attic cover insulator 120. Adding flooring and storage on top of fiberglass insulation will compress it squeezing out trapped air rendering it virtually useless. Energy saver eliminates the need to remove attic flooring and lose valuable attic storage space in order to make major energy saving upgrades in the attic.
Step 3 place caulking and furring strips. The superattic system from dr. Encapsulating the rafter or top truss chord roof framing members with spray foam will improve the energy efficiency of the attic space. This is because the effects of thermal bridging are limited which also results in the elimination of melt lines on the roof surface in cold climates.
When installing foam insulation boards in the attic make sure you start from one corner and work your way around the room. The superattic system utilizes proprietary silverglo rigid foam insulation panels to fully seal and insulate the attic directly beneath the roof rafters and directly inside the gable ends. Wood has an r value of about one per inch of thickness. In this situation the walls of a finished attic space or room would go with the roof line.
Also since the attic insulation rests on top of the drywall it will be much thicker than the bottom 2 4 chord of the attic truss. Add weatherstripping around the perimeter and a sweep to the door of a walk up attic.
