The product has a cross-section of two T-shaped elements and, due to the thin web, the cold bridging between the flanges is low. The thin wall also allows for better insulation of structures. I-Joist is significantly lighter than other engineered wood products, making them easy to install, drill, and cut. They experience minimal dimensional changes due to humidity, allowing them to be precisely cut to the required dimensions, thereby reducing the time required on site. I-Joists are constructed from wood, a renewable and easily recyclable raw material. The product also serves as a carbon sink for buildings. For instance, opting for one meter of I-JOIST (300 mm high) can help save up to 4.6 kg of CO2 in the structure. By choosing this type of structure design, you contribute to preserving the environment and combating climate change. By using I-JOISTS instead of sawn timber, we can save up to 47% of wood biomass. This indicates that when using I-JOISTS, we can construct two houses from the same harvest of forest timber, whereas conventional sawn timber would only be adequate for a single place of habitation.
