A Firring is a thin strip of timber (sometimes referred to as a ‘batten’) that has been cut along its length diagonally so that it tapers, with one end deeper than the other. They are used in the construction of flat roofs to create a fall to ensure water runs off the roof to the lower side.

Typically they are designed to a fall of 1:40, which given on-site inaccuracies should result in a minimum fall of at least 1:80 in the finished construction.

Firrings are sometimes referred to as furring strips or furrings.

They are manufactured by cutting at an angle along the length of a timber batten. As this requires specialist cutting equipment, they are often manufactured off site. The most commonly available sizes have a maximum cross section of 47mm x 50mm, 47mm x 75mm and 47 x 100mm

They are cut in pairs, with the pieces on both sides of the cut line being used, to reduce waste. They can be cut is identical pairs or folding pairs. Identical pairs are the same when cut, whereas a folding pair are cut to form a continuous piece when placed end to end.
