How to Insulate a Carport Roof
A carport, like attics need to be properly insulated. If these areas are improperly insulated a lot of energy is wasted. Proper insulation keeps the house warm in the winter and cool in the summer. Insulation controls condensation which in turn helps to avoid build up of harmful mold and it reduces corrosion in metals. Insulation also controls noise and the better insulated the room is, the less likely for noise to come through.
There are 3 types of insulation which can be used for your carport, attics or metal buildings. These are fiberglass, reflective insulation and foam board. Fiberglass is a material made from very fine fibers of glass, therefore its name. Foam boards can be used to insulate most parts of your home from the roof of the house to the foundation because they provide good thermal resistance and add structural strength to a home. Materials used in making foam boards are usually, polystyrene, polyisocyanurate or polyiso and polyurethane. Reflective insulation is also known as a radiant barrier and is made of an aluminum foil; it is designed to block heat transfer across open spaces and is most effective in hot climates.
Step 1 - Determine the Size of Your Roof
Measure your carport’s roof or ceiling, its length and its width to get the measurements of the insulation that you are going to need. Make sure to take the necessary precaution and wear a face mask or protective goggles, a dust mask, gloves and a hat. This is to protect you from the fiberglass insulation because it can get into your skin, eyes and lungs and cause serious irritation. It is also not a good idea to start this project on a hot day. Opt for a cooler weather when you attempt to install insulation of any kind.
Step 2 - Keep Materials Away from Heat Producing Systems
Insulation materials are highly flammable. It is important you keep yourself and the insulation materials at least 3 feet away from any heat producing mechanisms.
Step 3 - Place the Plywood and Insulation
You need someone to help you with this step, put the plywood over the ceiling joists and ask someone to lay out the rolls of insulation for you. The plywood works as a walking platform. Begin at the ends of the ceiling and work your way toward the center of the room. Remember that the paper facing of the fiberglass should be installed facing up. Firmly press the insulation into the joist bays and once you have reached the end of the joist bay you can cut the ends off with a utility knife or any sharp knife.
Step 4 - Staple Insulation in Place
Once you are satisfied with the placement of fiberglass insulation, you can now use and load the staple gun with staples and staple the fiberglass insulation in place. Make the staples at least 5 inches apart from each other. Be careful not to crush the insulation too much. The depth is part of what lets it work.
Step 5 - Stuff Tight Areas
Use the left over pieces of insulation to stuff into tight areas. You can use a broom handle to reach into tight spots.
If you are satisfied with how much insulation you have put on your carport’s roof then you are done, just make sure everything is in its place. Sometimes some ceilings or roofs need two layers of insulation, if you feel that you need to add more layers, just make sure that the second layer is at a 90 degree angle to the first layer.
