Finishing Attic Space With Trusses

Trusses are considered a superior method of framing a roof because of the additional support.

Finishing attic space with trusses.

It s a 12 12 roof so that s a good 11 at the ridge which even with new floor joists and a 5 knee wall should be plenty of room for a nice space. The sad fact is your builder could have installed attic trusses over this garage for just slightly more than what the existing trusses cost. The height of the interior box within the storage truss is usually never over 5 feet high. Look at this photo of the space created by attic trusses at my home.

Measure the width of your roof trusses from inside to inside. Trusses are like big structural triangles that have angled top pieces that serve as rafters horizontal pieces that serve as floor joists and interconnecting web pieces that give the triangle strength. Often a rectangular size space is created inside the overall large triangle of the truss. These trusses are often called light storage trusses.

Attic trusses have a rectangular shape inside each truss. The attic space is 22 on the side parallel to the trusses 28 on the other side. Here are some must do tips to follow when finishing your attic. I have this above my own garage.

Attic floors generally need to be reinforced with additional joists and a subfloor. If you ve measured your attic space and feel you have enough room to accommodate living space chances are you have rafters or you have special trusses called attic trusses which create a large open space under the peak of the roof. If you have trusses it will be next to impossible to reconfigure them to allow for clear space. Use a chalk line to draw a line along the floor parallel to the lower edge of the roof from one end of the attic to the other on both sides.

Cut each strip or batt to the exact length of the cavity. Ironically though it s the rafters that provide a better environment for an attic conversion because of the clear space. This framing style typically provides the most open space in an attic. Install new rolled insulation between the wall studs.

Press them in place and staple through the paper to the studs. The trusses are double cantilever style. The lyons used a web of 16 inch deep engineered trusses to accommodate wiring plumbing and ductwork then topped the plywood subfloor with oak or tile. If you have this type of roof framing you cannot finish your attic without rebuilding the roof.

When done without proper planning or adherence to local building codes it can actually reduce the value of your home or stall a sale. By contrast conventional trusses have supports called webbing that zigzag through the attic space. Install the rolled insulation in the floor by cutting to size pressing into the space between joists and attaching with wire fasteners. If you just desire storage space in an trussed attic that is also possible.

Newer truss framed roofs are made with prefabricated trusses.
