Use the species, strength class, section and treatment stated by the project design. Structural members should carry a visible grade mark, and spans or loads should not be guessed from appearance.
Construction Wood for Framing, Joinery and Finishing
Timber at MacBlair covers structural, construction and finishing work throughout a building project. The confirmed range covers joist and studding sections, treated timber, roofing battens, floorboards, cladding, door framing, mouldings, stairparts, skirting, architrave and window boards. Order against measured quantities and check the listed unit, length and pack information before work starts. building materials for the wider project provides context for the wider project.
Compare section size, finished size, length, grading, treatment and intended exposure. Use strength-graded material where the design requires it, treated sections where moisture or biological risk demands protection, and planed or profiled timber where appearance and accurate joints matter. Where the task continues into another part of the build, joist and studding timber can coordinate compatible materials.
Before work begins, acclimatise joinery timber where required, check pieces for damage or excessive distortion, and confirm that supports, centres and fixings match the design. Cut with sharp tools, seal or retreat cut ends when the treatment specification requires it, and keep structural members correctly supported while they are fixed. Measure carefully and allow for cutting or fitting waste. Test the method on a short length or inconspicuous area when appearance matters. skirting and architrave may support the next practical stage.
Timber performs best when it is kept off the ground, protected from rain and ventilated under cover. Coordinate the timber with compatible connectors, coatings and moisture details, and do not replace a specified grade or treatment class with a visually similar section. Follow product instructions, drawings and trade guidance where structure, fire, moisture or exterior exposure affects the choice. Store remaining material as directed.
Timber FAQs
Nominal size normally describes the sawn section before planing or regularising, so the delivered finished dimensions can be smaller. Check the listed actual dimensions before matching existing work.
Treatment is selected by the timber use class and exposure to moisture or decay risk. Confirm the application, protect treated surfaces from damage and retreat cut ends when the product instructions require it.
Measure each run and add a sensible allowance for end trimming, cutting plans, defects and mistakes. Profiled work can need more allowance because offcuts are not always reusable.
Stack it flat on level bearers, off the ground and under weather protection with ventilation. Keep joinery-grade material clean and allow it to acclimatise where the manufacturer recommends.
