Frequently Asked Questions:
What is rough-sawn timber?
Rough-sawn, untreated timber, also known as ‘carcassing timber’, is untreated wood that has been cut. By untreated, we mean that the wood has received no treatment from chemicals, stains, oils or adhesives. The edges and sides where the rough-sawn wood was cut will have an unfinished, rugged surface.
Rough-sawn timber can come in many different shapes and sizes and is one of the rawest wooden building materials. It is cut with a circular saw and does not undergo finishing work, such as sanding or polishing. For that reason, it is often cheaper to purchase. However, it retains more moisture than other types of wood because it has not been kiln-dried. Rough-sawn untreated timber allows woodworkers to alter planks to suit their needs.
It can be further cut, adapted, painted and varnished according to project specifications. Here at Beesley & Fildes, our rough-sawn wood is high-quality home-grown or European whitewood.
Can I use rough-sawn timber outside?
Rough-sawn timber can be used in outdoor projects. However, if you want to prolong the longevity of your build, treating your planks with finishing technology such as bonding agents, sealants, or paint is a sensible option.
Using untreated timber outdoors can pose several risks to your DIY project. Wet or moist untreated wood will be at risk of decay and rot. Chemical treatment will discourage the growth of fungi or moulds that can easily penetrate the porous surface of your planks.
Untreated wood can be similarly damaged by the Sun’s UV rays. Over time, exposure will decrease the wood’s natural oils and cause permanent discolouration. If you do not wish to treat your rough-sawn timber with a finishing agent, keeping your build in the shade may prevent sun exposure.
Is rough-sawn timber strong?
Rough-sawn untreated timber is ideal for projects where the strength of your wooden materials is most important. The wood is renowned for its strength, stiffness and durability, making it perfect for construction projects. Despite its strength, Beesley & Fildes rough-sawn whitewood is easy to work with and can provide excellent durability on a low budget.
Can I build my house with rough-cut lumber?
Rough-sawn timber should not be used for structural building purposes. The kinds of wood used to construct homes are typically chosen based on their graded strength and durability. Rough-sawn wood, however, is not strength tested to determine its load-bearing capacity. These strength tests determine how much stress the material can withstand and allow manufacturers to make accurate recommendations about where and how they should be used.
