Quality and Tolerance
We use the highest grade of slow grown tight grain northern pine and spruce for stability and strength. Other species
are available upon request.
To produce the best quality timbers, selected logs are sawn through the heart (centre) to allow for complete
drying. Then the timbers are kiln dried to a stable wood moisture level of the general geographic location where they
will be used. Well dried timbers can be profiled to more exacting tolerances with a clean, smooth, 'ready-to-stain' finish
not found in any other log wall system. The timbers are oriented in such a manner that the more durable, stable and visually
pleasing heartwood is on the exposed surfaces. This virtually eliminates undesirable checking, warping and settling common
in traditional log and timber homes. The resulting finished wall will appeal to the solid wood home enthusiast, as well as
attract future standard frame home owners, usually discouraged by the cost, rustic finish and maintenance of a traditional
log home.
The Twin Timber system therefore combines the best characteristics of any stud framed wall and solid log/timber wall
providing both insulation and energy storage/release.
