This treated timber firring is used to form a consistent slope on flat or low-pitch roofs, tapering from 47mm to 0mm over a length of 4.2 metres. It is commonly fitted above structural roof joists, timber, or steelwork to create the necessary gradient for water drainage.
Practical for both commercial and domestic applications, the firring aids in preventing water pooling and supports effective roof runoff. Pressure treatment provides added durability in exposed environments, making it suitable for long-term external use.
