This may very well mean that the top of the attic stair needs to face toward the center of the building structure where there is the greater overhead clearance to the rafters. That may end up placing it in the ceiling of a bedroom for example.Īnother thing to consider is to make sure that you are able to orient the attic stair so that it comes up at its top in a location that has plenty of head clearance under the rafters. The consideration of the rafter tie direction and subsequent placement of the attic stair location may very well place some constraints on where the stair opening can be located. It is often considered optimal to place the attic stair access in a hallway. This also means that you may need to be a bit more flexible as to where you locate the rough opening relative to what is built below the attic ceiling. A high level of structural stability is achieved by the diagonal structure of a minimum of three positions. The calculator can be used for any linear material whether it be steel, metal, wood (timber), plastics, etc.
JOIST CUTTING OPTIMIZER FREE
CLT is composed of multiple panels that are arranged at right angles and are diagonally superimposed on top of each other. Our free online cutlist optimizer can be used to work out the best way to cut your lengths of material to get the most efficient cuts from the material and save wastage.

This is the reason why you want to minimize the number of these cross ties that you end up cutting into. The abbreviation cross laminated timber (CLT) is the umbrella term for solid wood panels used in the building industry. Instead you have open rafters that depend almost completely on the rafter cross ties to triangulate the rafter structure and keep the building side walls from spreading out at the top due to roof loading. This way you only need to cut one of them to make the room for the rough framing opening.Īs evidenced from your pictures of the attic area, your roof support structure is not created from engineered trusses.

Just measure, mark the line, put the tool in the web, line it up with the mark and cut. The Cutrite can be used to cut both 9 1/2 inch and 11 7/8 inch joists. It assures that every cut is straight, square, fast and accurate. To make the short rafters, one person held the TJI down to the horses while another one made the cut. By the end of the class (about 90 minutes), they had two-thirds of the TJI roof rafters cut and ready for installation. Instead you should place the cutout opening inline with the ceiling joists/rafter ties. The Cutrite is a circular saw guide that makes cutting wooden I-Joists quick and easy. First, they made I-joist cross-cutting jigs from OSB scraps and made a few practice cuts. n Power Joists are manufactured up to 64’ in length.

n Power Joists of the same depth are manufactured with various ange widths ange width is an important design consideration when specifying hangers. You potentially compromise too many of the rafter cross ties by doing that. n Power Joists are available in eight depths: 9-1/2, 11-7/8, 14, 16, 18, 20, 22 and 24. I would not put the attic stairs/ladder assembly opening at right angles to the ceiling joists.
