Frequently asked questions
Treated Timber
Treated timber has been infused under pressure with chemical preservatives that help protect it from insect attack and decay. Common preservatives used include copper azole, alkaline copper quaternary (ACQ) and copper naphthenate. The treatment process allows timber to better withstand exposure to moisture, mould growth and pests. Overall, treated timber maintains its integrity and strength when weathered over time.
Using either C16 or C24 treated timber is the primary choice for a variety of projects including decking, fencing, retaining walls, raised beds and gazebos. The sturdy nature of properly treated wood prevents sagging, warping and rotting. As a result, this reduces the need for frequent repairs or replacements.
Since treated timber resists insects and mould, it can last between 15-20 years with minimal upkeep. This saves time and money over using alternative materials that require ongoing maintenance and care.
CLS & Studwork
Canadian Lumber Standard (CLS) timber is premium quality softwood lumber that is kiln-dried and precision milled to exact dimensions. CLS-certified framing studs and boards provide very straight and stable wood pieces that are ideal for all construction projects. Since CLS lumber has an approximate 19% moisture content, the risk of warping and twisting is significantly reduced once installed. This results in wall and floor environments that feel solid without problematic squeaks or shifts.
CLS timber is exceptionally well-suited for stud work in new residential construction as well as remodelling projects. The reliability of CLS framing creates walls that are straight and plumb. This produces flat surfaces for drywall sheathing installation and a base structure properly prepared for finishing materials. Using quality CLS studs for framing saves time during construction and provides dimensional stability for the life of the building.
PSE
Planed square edge (PSE) timber is smoothed and squared on all four sides by an industrial planer. This machine processing removes uneven and rough surfaces, exposing clean 90-degree edges along the length of boards, beams, planks and posts.
The uniform edges and smooth faces of PSE wood allow for tighter fitting joints during construction projects. When fastening one piece of PSE timber to another, the seam closes neatly without irregular gaps or overlaps. This helps with quick assembly, provides better structural integrity, and delivers more aesthetically pleasing finished projects like cabinetry and furniture.
During the finishing stages, PSE timber offers an additional edge as its uniformly flat surfaces do not require further planing or sanding. The smoothness enables the direct application of stain, paint and clear coating without the need to hand plane or smooth rough-sawn wood. Prepped PSE material saves time during the construction and finishing phases.
