In building and construction Softwood timber can be split into two areas of use, Carcassing and Joinery
Carcassing timber has a lower visual quality than timber that is used in Joinery products; it may contain more knots and have a less attractive grain pattern, Carcassing has structural application. Most of Bradfords Carcassing and structural timber has planned sides and rounded edges to make it easier for you to handle, though a sawn finish which has had no additional planing is also available.
Timber used in structural applications may have a higher moisture content then timber used for joinery products.
Carcassing timber is graded for strength;
Common uses for Carcassing, CLS, Batten and other types of structurally graded timber include:
- Floor Joists
- Ceiling Joists
- Partitions and Stud Work
- Timber Frame Buildings
- Roof Timbers – Pitched and Flat
- Trussed Rafters
- Water Tank Supports
Timber that is used in Joinery products are selected for their high visual quality and are graded according to for their aesthetics and some structural properties, these types of timber are often used in places which are visible at the end of construction, for example:
- Boarding & Cladding
- Planed Square Edge (PSE), this can also be referred as Planned All Round (PAR)
