This treated timber firring measures 47mm by 100mm, tapering down to zero over a 4.8 metre length. Commonly used in roofing, it is designed to create the necessary slope on flat or low-pitch roofs to support effective water runoff.
On site, the firring is fixed onto roof joists or decking to achieve the required gradient. Its treated timber construction offers resistance to moisture, making it suitable for installation on residential or commercial roofing projects where control of surface water is needed.
