4 inch Carcassing Timber is a natural product - variations in knots, colour, and grain should be expected - They are allowable. A certain amount of checking and splitting occurs, and is allowable in the Grading Specifi­cation; 100mm Timber can be Grade-Stamped for strength, where required.

Due to it's thickness, and the length of time taken to kiln-dry it, 100mm Graded Carcassing timber is usually air-dried "in-stick"; Unseasoned 100mm timber can have a moisture content approaching the maximum saturation level of 27%, when air-dried "in-stick" this can fall to 20-23%, and if kiln-dried the moisture level is brought down to 18-20%. Generally in a heated building, the moisture level can be 8-10%, and it is here, when the moisture level of timber is rapidly changed, that twisting, warping and splitting can occur.

We keep tilt-fillet in stock and can cut firring pieces and other timber sections to size for flat-roof and pitched-roof work.

Sizes may be the usual timber nominal size that the 4 inch Carcassing Softwood is cut from, with a finished size that is generally obtained; Carcassing Timber sizes are generally ±6mm on thickness / ±10mm on width, ±40mm cross-cutting tolerance & there may be one splitter saw cut-edge; This is the size immediately after machining the timber, and does not take into account any movement later, caused by moisture movement into, or out of the 100mm Construction Timber. ( Be aware: For many reasons, size, profile and other aspects of timber may vary from batch to batch, so it is best to purchase all you need for a job in one go, rather than buying more at a later date. )
