Thermally Modified Hemlock is an all natural building material produced and manufactured in the USA. Thermal modification uses high heat to remove organic compounds from the wood cells. The result is a wood product that does not absorb moisture, expand, contract, warp or become a food source for insects. This process allows you to enjoy the beauty of natural wood in both interior and exterior applications without the worry of rot, decay or harmful chemicals.
- Made in the USA – This means no international shipping costs with the quality you would expect of an American made product.
- Rot resistant – This product is durable and completely resistant against rot and decay, making it suitable for exterior applications.
- Stability – Thermal modification reduces cupping and warping so it lays flat and is easier to work with.
- No chemicals – An advanced steam treatment process means that chemicals are never used, making this a product great for both interior and exterior applications.
- Economically priced – This product makes an excellent alternative to a higher priced clear Western Red Cedar.
- Uniform color – Hemlock is naturally light and uniform in color, meeting the demand for this trend in many modern projects.
- Easy to finish – Hemlock accepts stain easily, giving you limitless color options with a variety of finishes.
- Environmentally friendly – The closed vacuum steam process is chemical free with lower temperatures, requiring less energy which makes this locally sourced material a better product for the environment.
