How to Reflect Heat with Radiant Barriers
Heat radiant barriers are fitted to the rafters in your roof to prevent heat from escaping in the winter. They also prevent the attic from getting too hot in the summer. All in all, a heat radiant system can make your home much more energy efficient since you won't be spending as much to heat your home. Here is how to install a radiant barrier from start to finish.
Step 1 - Prepare the Attic
First, prepare your attic so that you can work properly and safely. Most attics are not boarded, meaning that it's very easy to put your foot through the ceiling. Use large boards that are big enough to span across the joists. Lay these on the joists in your attic to create a work area that is large enough to operate in.
You will need to have access around the perimeter of your roof so that you can fix the heat radiant barriers onto the rafters in the roof. Don't attempt to balance yourself across the rafters when doing this sort of project.
Before you can work in your attic you might need to clear out all the junk that's in there. You will also find it much more comfortable to work during an overcast day. Working on a hot day will be very uncomfortable.
Step 2 - Measure Your Roof
Measure the width and height of your roof to make sure you have enough panels to fit all the way around the roof. Plan how the panels will fit, and make sure that they will be fixed into all of the rafters.
Step 3 - Cut the Heat Radiant Barrier
Cut the barriers to size using a knife or a saw. Make sure they all fit together properly; the better they fit, the more efficient your home will be.
Step 4 - Fitting the Panels
Once you have cut the heat radiant barriers to size, you need to fit them to your roof. Staple them onto the rafters using a staple gun. Before stapling, put the individual panels up against the rafters to make sure they will all fit properly. This will make sure the panels are fitted securely and won't move. If there is any extra barrier material, trim it off, and then fill any gaps between the panels using caulk.
