Soffit boards are used to close the gap at the eaves between the rear of the fascia board and the wall. Soffit Boards are 10mm in thickness with a single rounded egde. They are 5M in length. Plain soffit boards are fixed in position using 40mm polytop pins spaced no further apart than 600mm. Each length is connected to the next using RT20 H section joint trim. This trim is also used to join the soffit at the corners of the eaves.
Soffit boards come in a range of sizes between 100mm and 404mm.
