The purpose of your backyard shed is to protect and store all kinds of materials from paint to sports equipment. In summer, the internal temperature of a wooden shed can climb above 120 degrees F. (56 C.), which can damage rubber items, and is hazardous to all solvents. Installing heat vents will allow hot air to escape, preventing these problems. The inside of your shed will stay comfortable for you to work in it. Follow these directions to install heat vents in your shed.
Step 1: Consider the Type of Vents You Need
If you live in an area with moderate winter weather, use fixed vents. If heavy winter snowfall and drifting are common in your area, purchase vents that have closable louvers to keep snow out.
Step 2: Measure the Size and Location of the Heat Vents
You will need at least four heat vents, a pair near the roof and a pair at ground level for every fifty square feet of shed area. Measure the vents and the walls of the shed so you can cut holes to fit the vents exactly.
Step 3: Cut Holes for the Vents
With the power saw, cut holes for the heat vents close to the roof peak, into opposite ends of your shed. Do the highest holes first, and align the floor-level holes with them later.
Step 4: Fit the Vents into the Wall Holes
Insert the heat vents into the upper holes, and screw them into place. Cut a section of wire screen about 2 inches larger on each side to fit over the vent openings. This will keep out insects, windblown leaves, seeds and petals from flowering trees. Attach the wire screen securely with screws or industrial staples.
Step 5: Measure and Cut the Floor-Level Holes and Install Vents
Vents at floor level will allow cool air to enter the shed. Measure to align the floor-level vents with the roof peak vents. Cut suitable holes and install the heat vents, and shield the inside of the vents with sections of wire screen.
Step 6: Adding Floor-Level Vents to a Metal Shed
A metal garden shed will usually come equipped with roof vents, but it might not have floor vents. To add floor vents, buy a pair in a suitable size, and cut holes in the metal walls carefully with a metal saw or tin snips. Use bolts instead of screws to install them. Drill bolt holes and attach the vents with bolts, securing them with nuts on the outside wall. As with the vents for a wooden shed, put wire screening over the vent holes to keep out insects and leaf debris.
