Roof laths span across between the rafters and support the wood shingles. A lath or slat is a thin, narrow strip of straight-grained wood used under roof shingles or tiles, on lath and plaster walls and ceilings to hold plaster, and in lattice and trellis work. [1] Lath has expanded to mean any type of backing material for plaster.

In their most basic form, laths (or lathes) are traditionally timber strips attached to a stud frame. This studwork frame is usually comprised of panels. These are fixed onto the floor and ceiling. The wooden strips, or laths, have gaps between them that allow plaster to settle behind and bond more strongly to the lath itself. Once the plaster has ...
Before you begin work on your laths, ensure that they are clean. This includes being free from any greasy substances, dirt, or plant matter. Similarly, if the laths are damaged in any way, they should be replaced prior to plastering. At Best of Lime, our Douglas Fir lathsare sawn 'green', so have a raised grain texture that also acts as a key for t...
At Best of Lime, we find the easiest way to illustrate the correct spacing of wooden laths is through 'Goldilocks'. Use your little finger as good guide - the gap between the laths should be around 1/4 of an inch, or the width of the average little finger. The first set of photos show laths that are too close, and the plaster won't push through to ...
There are two key benefits to wooden laths: their sound-proofing properties, and their role in delaying the spread of fires. In comparison to modern plasterboard, lime plaster and laths play a role in absorbing sounds, particularly low frequencies. Due to the non-uniform keys, echoes can also be deflected. It is also proven that lath and plaster ca...
The question is not howwe use timber (or metal) laths, but should we be using them at all? At Best of Lime, we develop and manufacture low carbon lime plasters for use internally and externally. We like to think that the longevity of our plaster is measured in generations. The use of timber lath ticks the conservation box, but the thermal efficienc...
Like laths, they can be crafted from timber like wood pine, including steel and PVC. Roof batten sizes range from 1 to 3 inches in width and varying lengths to suit unique project needs. Roofing Lath vs Batten. Understanding these differences empowers you to choose the right material for your projects: Material and size differences
The laths are usually around 25mm wide and 6mm thick. There is usually around a 6-8mm gap between each lath to allow the lime plaster to push through and form a kind of hook. Laths can be made from hard or softwood, although hardwood is usually recommended for ceilings. Lime plaster is a traditional form of plaster that uses lime putty as a base.
Jun 14, 2022 · Lath and plaster ceilings are made up of laths – thin strips of wood, around 25mm wide – covered in a lime-based plaster that has often been combined with coarse animal hair, such as goat or horse, for added stability and flexibility. The laths are nailed horizontally directly to the ceiling joists before the lime plaster mix is worked into ...
Lath and plaster is a building process used to finish mainly interior dividing walls and ceilings. It consists of narrow strips of wood (laths) which are nailed horizontally across the wall studs or ceiling joists and then coated in plaster. The technique derives from an earlier, more primitive process called wattle and daub.
