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, where the moisture level of timber is rapidly changed that twisting, warping and splitting occurs.

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

Carcassing Timber is a natural product - variations in knots, colour, grain and surface-checking should be expected.

Sizes are the usual timber nominal size that the Buildng Timber is machined from, with a finished size that is generally obtained;
(Be aware: For a multitude of reasons, size and profile 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 graded timber is cut, then this may affect the timber-joist grade rating, and may cut off the timber grade-stamp;
If Size, Pattern or Grading of the Timber Joist is important, then you need to check this with your Building Inspector before ordering the timber with us, 
and before commencing work. We cannot be held responsible for any variations in Carcassing Timber sizes, pattern or grading.)

Price is generally per running metre or per length - we can price larger quantities and pack lots per cubic metre.
