This treated timber firring is cut to 47 x 75mm, tapering down to 0mm over a length of 3.6 metres. It is intended to form or improve the slope on flat or low-pitch roofs to assist with effective water run-off.
Often fitted above joists before applying roof decking or coverings, the firring helps prevent water pooling. It is suitable for both residential and commercial roofing projects where managing surface water is essential for ongoing building maintenance.
