TrimJoist
As the name indicates, TrimJoist open web trusses are easily trimmed at the jobsite, effectively eliminating the need for custom made floor trusses. The TrimJoist design also boasts a center duct chase (strut webbing) for plumbing, electrical and duct work. TrimJoist products are extremely well engineered and are available in two foot increments from 4' to 28'. We stock 16" depth but 11 7/8", 14", and 18" are available through special order.
Solid 2x joists are cheaper on a per unit basis. However, studies have shown that by the time culls, waste and labor are considered, a more superior TrimJoist floor system could have been installed.
Because TrimJoist products use 2x4 raw materials, the environmental impact is much smaller than the loss of large old-growth trees that are required for traditional joists. Approximately 35% of each TrimJoist is recycled material.
