Thermally modified wood is natural wood enhanced through a controlled heat and steam process. The process changes how the wood responds to moisture, improving dimensional stability and durability without relying on traditional chemical preservatives. 

Compared with standard kiln-dried wood, thermally modified wood absorbs less moisture and is less prone to swelling, shrinking, warping, twisting, and cupping. It also offers improved decay resistance in properly designed above-ground applications.

Common applications include exterior cladding, soffit, fascia, trim, decking, porch flooring, exterior millwork, and select interior walls and ceilings. Suitability depends on the species, profile, finish, installation method, exposure, and project conditions.

Common options may include Hemlock, Spruce, Southern Yellow Pine, and Paulownia, with other species available by request or current supply. Final species selection should be confirmed during estimating and physical sample approval.

Rustic Mix offers the greatest natural character, including mixed grain, knots, and color variation. Clear Mix provides a cleaner face while still allowing mixed grain. CVG, or Clear Vertical Grain, offers the most uniform vertical-grain appearance and is the most selective option. SYP, or Southern Yellow Pine, is a species group known for bold grain, warm color, and pronounced growth rings.

The approved physical sample establishes the project's color direction, but wood is a natural material. Variation in color, grain, texture, and finish absorption should be expected within an order and between separate production runs.

Yes. Exterior wood naturally changes with exposure and may gradually develop a silver-gray patina. South- and west-facing elevations typically weather faster, while shaded walls, soffits, and areas beneath deep overhangs may retain color longer.

Yes. Vintage Woods offers factory-applied finishes and a variety of standard and custom profiles, including shiplap, tongue-and-groove, square-edge, trim, and fascia profiles. Actual dimensions, coverage, reveal, and finish should be confirmed on the estimate and approved physical sample.

No. It should not be used in direct ground contact, continuously wet conditions, or assemblies that trap moisture. Proper drainage, ventilation, flashing, and clearance from moisture-prone surfaces remain essential.

Thermal modification can reduce certain strength properties. Any structural or load-bearing use should be reviewed and approved by the project's architect, engineer, or other qualified design professional.

Clear Mix and CVG are accumulated selections. Qualifying boards are collected from limited portions of the log over time, resulting in lower recovery, slower inventory accumulation, and higher relative pricing.
