Firrings Price Calculator

We cut our firrings from timbers to your bespoke sizes. Their purpose is to form a slope or taper on flat roofs to make sure the rain water runs off. They are fastened(using nails) to the top of existing joists and then sheeted over. Our firrings are 44mm thick, approximately. See the diagram below which illustrates the general shape of a firring. same diff errorsame diff error


As a guide for deciding on firring height a minimum of 1 in 80 fall is usually required, e.g., a firring of height 60mm will have to be less than 4400mm(60mm - 5mm x 80) in length to achieve this gradient. Please choose from our standard heights or enter your own height from the height menu below.WARNING: If you select the semi-treated timber option the treatment will be cut away from the tapered edge and maybe from the bottom edge as well. Enter your required length and quantity and press enter.
