Siding Product Configurations
When Trestlewood quotes 1,000 square feet of a specific siding configuration, it is quoting enough material to provide 1,000 square feet of coverage based on default installation assumptions and 0% installation falldown. Buyer should order enough product to cover anticipated installation falldown and the impact of any changes to installation assumptions. Siding configuration options include:
(a) Board to Board (common widths: 4", 6", 8", 10", mixed)
(b) Board and Batten (common board widths: 8", 10", 12"; typical batten width: 4"; assumed: installed with 2" gaps between boards)
(c) Board on Board (common widths: 6", 8", 10", mixed; assumed: installed with 1" overlap on each edge)
(d) Shiplap (common face widths: 5", 7", 9" (often actual face widths of 4 7/8", 6 7/8", 8 3/4"); target thickness often 3/4"+/- for NatureAged and 11/16"+/- for Antique and WeatheredBlend; most commonly, 3/8" shiplap joints are milled on opposite edges and opposite sides of boards)
(e) Wedgelap w/ Rabbet (from antique corralboard, typically not available in NatureAged or WeatheredBlend; common face width: 7" (typical actual coverage of 6 3/4"); generally cut from 2" lumber to 1 1/4"+/- on thick side and 1/4"+/- on thin side, with rabbet then added; mixed grays and browns (to allow both sides of 2" lumber to be used; back side would often be pressure-washed to soften (but not eliminate) striping that is typical of back side corralboard))
(f) T&G (common face widths: 3", 5", 7", mixed; target thickness often 3/4"+/- NatureAged and 11/16"+/- Antique and WeatheredBlend; fit of barnwood siding T&G often not quite as good as flooring T&G)
Unmilled siding products (a, b, and c) are standard barnwood lumber. Targeted thicknesses and widths of milled siding products (d, e, and f) are generally driven by barnwood lumber inventory on hand. The milling process generally reduces but does not eliminate variation in actual thicknesses and widths (across boards and even within specific boards.) The milling process often creates additional character like loose or fallen out knots. Such defects are generally left in the boards; buyer can decide whether to install them as is, cut them out, or fill them. Kiln drying lumber prior to milling it can increase the tendency for knots to become loose during the milling process. The average length of siding boards (especially milled siding boards) will generally be less (sometimes significantly less) than the average length of lumber boards. Siding square foot prices will generally be somewhat to significantly higher than lumber board foot prices because they reflect more material and, in the case of milled products, additional processing costs.
Trestlewood makes no representations about the fitness of its products for use as siding or in any other application. It is ultimately the Buyer's responsibility to (a) determine which products (and their accompanying characteristics) are acceptable for use on its project and then to (b) make sure these products are handled and installed correctly. While Trestlewood is not a construction or installation expert, it does periodically pass on (without any guarantee of accuracy) information/resources to its customers that it thinks might provide helpful starting points to consider - see, for example, Trestlewood's 6/2/2016 blog post "Thoughts to Consider Prior to Wood Siding Installation" and other blog posts/resources on www.trestlewood.com.
