NatureAged Timbers are generally produced by laying fresh rough-sawn timbers out to weather. NatureAged Timbers are generally mixed species (usually softwoods; often Firs and/or Pines (with the most common species being Douglas Fir.)) NatureAged Timbers can include a mix of gray and brown color tones.
NatureAged Timbers are generally less stable than reclaimed/antique timbers and more stable than new/green timbers.
Trestlewood has developed special proprietary juicing processes that we sometimes use to accelerate the natural weathering process; help fresh-sawn faces blend in with weathered/aged faces; and/or help dial in desired color tones and/or other characteristics. Juicing, for example, seems to make it more likely for NatureAged Timbers installed in certain exterior applications/environments to retain gray color tones for longer (rather than weather brown.) Trestlewood calls NatureAged Timbers that have gone through a juicing process "Gray+". If NatureAged Timbers are not specifically quoted as "Gray+", Trestlewood can fill the order with any combination of Gray+ and/or non-Gray+. Trestlewood makes no representations about how long NatureAged Gray+ Timbers will stay gray in various environments/situations - we do not have enough experience/data to know this.
NatureAged Timbers can often be grade-stamped.
|Species||Mixed Species, heavy to (and often exclusively) softwoods. May include Douglas Fir, Alpine Fir, White Fir, Lodgepole Pine, Ponderosa Pine, others. Trestlewood can include hardwood timbers (RubyOak/RubyHardwood and other) at its discretion (see WeatheredBlend Hardwood Timber Spec Sheet #6160 and RubyOak/RubyHardwood Spec Sheet #s 6140 and 6147.)|
|Source||NatureAged Timbers are naturally weathered to achieve a rustic grayish/brown appearance. NatureAged Timbers may be i) new timbers; ii) timbers reclaimed from various salvage projects, iii) timbers cut from beetle-killed, fire-killed or dead-standing trees, and/or iv) timbers cut from material which has weathered out of spec.|
|HC/FOHC||Generally Heart Center (HC)|
|Metal||Allowed, but not as common in NatureAged Timbers as in many other weathered timbers.|
|Holes||NatureAged Timbers may have nail holes and/or bolt holes. Such holes will often have staining around them.|
|Checking/Cracks||Timbers generally have checks from the heart center to the faces of the timber. In addition, timbers can have surface checking and cracks, moderate butt checking and minor end splitting.|
|Moisture Content/Stability||The moisture content in NatureAged Timbers will vary from piece to piece. NatureAged Timbers are generally not as stable as reclaimed timbers, but are often more stable than green timbers. All wood has the tendency to move to equilibrium with its environment and will, therefore, expand/shrink/move as its environment changes.|
|Surfacing||Weathered. Original surfacing (prior to weathering) is generally rough-sawn (circle-sawn or band-sawn) but can in some cases be planed. Surface degradation (water damage, surface rot, punkiness, etc) is allowed.|
|Standard Dimensions||a) Cross-sections: 4x6 to 12x12 (larger dimensions are often available); b) Lengths: to 20' (longer lengths are often available); c) Nominal: dimensions are generally nominal; actual dimensions vary from timber to timber and sometimes even within a timber.|
|Weight||Typically, approximately 3 pounds per board foot|
|Grading||NatureAged Timbers can often be graded (WLCB, WWPA, or similar) for an additional charge. It is highly recommended that any timbers that are to be used in a structural application be graded. It is also recommended that standard size timbers be used whenever possible. Checking can often be more pronounced in timbers wider and/or thicker than 12" than in standard size timbers.|
|Appearance Variation||Weathered timbers will generally vary in appearance from piece to piece and even within a piece. The weathering (amount, mix of colors, etc) and other characteristics of one face can be substantially different than the weathering and other characteristics of another face. Some weathered timbers are cut from larger weathered timbers, giving them one or more fresh-sawn faces. |
Trestlewood sometimes uses one or more "juicing" processes to help fresh-sawn and/or less weathered/aged faces blend in with weathered/aged faces. All else being equal, juicing is more likely to be used in situations where (a) timbers are cut from larger timbers (thereby creating fresh-cut faces); (b) Buyer wants all (or most) faces to look weathered/aged; and/or (c) Buyer desires to increase the consistency of the weathered/aged look from face to face.
