Hollow Soffit Boards - 10mm Black Smooth

We offer black smooth finish hollow soffit boards that measure 300mm in width and 5000mm in length.

Hollow soffit is a cost-competitive and effective to traditional plain soffit boards and can be used lengthways, but it is more commonly cut into short sections that fit together side by side along the soffit using the integral tongue and groove.

To calculate how many lengths of hollow soffit you will need when using it in short sections, first measure the soffit gap in millimetres (the gap between the fascia and the wall). Divide 5000mm by this number. This will give you the number of pieces that you will get out of each full 5m length. Now multiply this by 300 and the resulting number is the length in mm along the wall that these pieces will cover.

Example:

Soffit width is 200mm.
5000 / 200 = 25. 
25 x 300 = 7500, so one length of 300mm hollow soffit will cover 7.5m.
