3 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; 75mm Timber can be Grade-Stamped for strength, where required.

Most sizes of 75mm Graded Carcassing timber are kiln-dried; Unseasoned 75mm 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 3 inch Carcassing Softwood is cut from, with a finished size that is generally obtained; 75mm Carcassing Timber sizes can vary ±8mm on thickness / ±10% on width, ± 50mm cross-cutting tolerance and there may be splitter saw cut-edges; 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 3 inch Construction Timber. The 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.

If any 75mm Graded Timber is cut or machined, then this may affect the Timber-Joist Grading, and also may cut off the Timber Grade-stamp;

3 inch Building Timber needs suitable external treatment, finishing and maintenance for exterior use; External use of 75mm Building Timber is at your own risk. - unless we have had the timber specifically vacuum-treated for you, with a guarantee certificate.
