Heat radiant barriers are fitted to roof rafters to prevent the escape of heat and keep the area from getting too hot. Barriers feature highly reflective material that re-emits heat instead of absorbing it. They reduce the transfer of radiant heat from the underside of your roof to other attic surfaces. This makes home heating and cooling systems more efficient. Reducing the amount of energy it takes to heat or cool the home lowers your energy bill.
You will need:
Step 1: Remove all items stored in the attic. Prepare the attic for this project by boarding the floor if it is not already boarded. Balancing on rafters while installing barriers is dangerous and not recommended. Instead, purchase large boards that span the joists and lay these on top of the joists to create a work area. You will need to access the roof perimeter in order to affix the barriers onto the roof rafters. Select an overcast day for barrier installation because temperatures will be more comfortable in the attic.
Step 2: Use the tape measure to measure the height and width of the roof. You will need enough barrier panels for the entire area. Determine how these panels will fit on the rafters.
Step 3: Use a saw or knife to cut the barriers to size so they fit together correctly to cover the entire roof area. Home energy efficiency is determined by the fit achieved.
Step 4: Staple each barrier panel onto the rafters with the staple gun, using as many staples as necessary to get a secure fit. Use the knife to trim off any extra pieces. Fill gaps between panels with caulk.
