Is my attic strong enough for storage?
As long as they are not damaged, the joists should be strong enough to allow you to move around in the attic for an inspection and to provide storage for typical boxed items.
The joists should support your weight, but the space between them almost certainly will not..
How do I install a subfloor in my attic?
Position the plywood sheet so that the longest side of the sheet lies perpendicular to the joists and the ends of the plywood lie directly on the chalk lines. If the plywood overhangs the chalk line and joist, measure and cut the plywood accordingly. Leave a 1/4-inch gap between the attic wall and the plywood edge.
Can you overload an attic?
Some attics do not have a full floor, and heavy objects could eventually fall through drywall, compromising your ceilings, and endangering the household members who are living under the attic space. Even when flooring is present, avoid overloading any areas to ensure safe storage.
Should I put a floor in my attic?
Since an average attic needs 16 inches or more of insulation, the insulation is always thicker than the ceiling joists or trusses. As such, adding a floor can cause the insulation to compress, thus reducing the efficiency of the fiberglass insulation.
How thick should Plywood be for attic storage?
3/4-inchYou need 3/4-inch plywood. The thinner plywood is acceptable when the joist spacing is 16 inches. If you plan to finish the floor in the attic and turn the room into a living space, however, you should always use 3/4-inch plywood.
How much weight can Attic support?
As Larry said, don’t overdo it. A person might think that going by the 10 lbs psf limit, that he could safely put 270 lbs on a 4×8 sheet of plywood (270 + 50 lb sheet of plywood = 320 lbs, or 10 lbs/sf.) If you weigh 250, that means you could safely have 20 lbs up there with you on one sheet of plywood.
What is the best flooring for an attic?
Resilient flooring, such as laminate or vinyl, is one of the best choices you can make for attic floors. This type of flooring can soften the sounds when installed over an underlayment.
Should I insulate my attic floor or ceiling?
1. In unfinished attic spaces, insulate between and over the floor joists to seal off living spaces below. If the air distribution is in the attic space, then consider insulating the rafters to move the distribution into the conditioned space.
Can you put insulation on top of attic floor?
A. Without removing the flooring, you have the option of blowing loose-fill insulation (fiberglass or cellulose fiber) over the top of the floor. … Another idea would be to roll out fiberglass batts on top of the floor. Butted tightly together, they would improve the thermal performance of this part of your attic.
How do I put plywood in my attic?
Carry a piece of plywood to one of the far corners of the attic and lay it on top of the installed boards. The plywood should be perpendicular to the joists so that a signal sheet spans multiple ceiling joists. Cut the plywood to fit so that each end of the plywood boards lands at the exact center of a floor joist.
How do I walk in my attic with blown insulation?
Unless you can safely traverse the attic in the truss webbing or on boards suitable to crawl/walk on, its best to stay out. If you find blown in cellulose and can’t see all areas, say so and move on. No, it would be unsafe to enter such an attic.
Can you convert an attic with trusses?
Attic conversions are now possible by replacing the truss rafters with A-shaped trusses or horizontal beams, which in return create additional space. … Replacing the standard W-shaped trusses with steel beams across the length of the floor allows you to create a much larger and functional attic space for the house.
Can you put plastic over insulation in attic?
4 Answers. Plastic isn’t recommended in this situation because it would create a second vapor barrier that can trap moisture and result in condensation and mold. Craft paper would have the same problem, this is what is most likely on the other side of the insulation for the vapor barrier you want.
Can you over insulate an attic?
But there may be a theoretical point of “too much.” If a home is over-insulated and is too tightly sealed, moisture can get trapped inside. Without proper ventilation, a home can build up too much moisture, especially in the attic (warm air rises), which can cause mold problems and, overall, lower indoor air quality.
Can you cover attic insulation with plywood?
Once the insulation is down, you can turn your attic into valuable storage space by covering the floor with plywood. It will also make the attic a safer place in which to walk.
How do I know if my attic can be finished?
