Thermowood Siding from G Wood Pro

G Wood Pro

G Wood Products, the exclusive distributor of Tantimber thermally modified wood products, bringing beauty, value, and increased durability to your next building project with its siding offerings. Thermowood, a relatively new technology, is made when hardwood and softwoods are expertly treated in a specific, environmentally friendly process that “cooks” the wood, removing sugars, moisture, and strengthening the wood as well as its durability. 

Why Choose Thermowood Siding?

Thermowood is durable enough to handle extreme weather conditions in any climate, on top of being an aesthetically attractive choice for decorative purposes in plenty of architectural applications. While all wood will expand as it absorbs moisture and contract as it dries, Thermally modified wood absorbs much less moisture than other timber choices and therefore will suffer much less from moisture deformities.

During the modification process of Thermowood, the sugars are removed. These sugars are the natural food sources of mold, bacteria, and insects. Without their presence in the modified timber, the resulting wood is much more resistant to rot, decay, and insect infestations, giving it a much longer lifespan.

In addition to being a great insulator due to the unique composition of the timber after modification, Thermowood comes in a variety of different types of hard and softwoods. Ash and Pine are popular choices, but each type of timber has its own unique attributes and distinct aesthetic to further customize your choice, and perfectly suit your project.


G Wood AshThermally modified Ashwood is a hardwood with a high number of growth rings, giving the dark chocolatey brown colored wood a beautiful wavy aesthetic with a tight grain structure that is free of the knots that most other hardwoods sport. One of the most popular choices for Thermowood, Ash is the best alternative to traditional timber, being durable, strong, multi-purpose, and appreciated for its great finishing qualities. Ash Thermowood has a biological lifespan of at least 25 years.


G Wood pineThermally modified Pine is a lighter caramel-colored softwood that is sought after for the natural aesthetic its knotty appearance offers. This low-density wood is easy to work with and has been used for centuries in woodcraft. Naturally resistant to warping and mold even before being thermally modified, the attractive Pinewood is often a favorite for nature lovers as well as being an economical and durable choice. Pine has a biological lifespan of between 15-25 years.


G Wood ayous sidingAyous timber is a light almond-colored hardwood that takes on a more refined, elegant appearance after thermal modification. Easy to work with, Ayous is a softer hardwood, allowing for it to be both lightweight and durable. Sustainably sourced from Africa where it is native, exotic Ayous wood has been used in a variety of applications for woodworking due to being exceptionally durable – even in the most extreme conditions. Ayous wood has a biological lifespan of between 15-25 years. 


G Wood IrokoIroko is a naturally durable hardwood with a similar color and structure to Ayous. Sporting a beautiful light amber color, Iroko, sometimes referred to as African Teak, is naturally durable and resistant to insects and rot. Thermal modification enhances its natural abilities, making it even less likely to expand or contract. This hardwood’s impressively long biological lifespan is expected to last a minimum of 25 years.


G Wood TulipwoodTulip Thermowood is a lightweight hardwood that is a favorite of many due to its unique texture and rich brown hue. Tulipwood has a natural appearance being straight-grained with a fine texture, sometimes exhibiting a blister figure in the wood. Despite being lightweight, Tulipwood is naturally strong and has a long service life of 15-25 years, making it an ideal choice for many who want a durable, but natural-looking wood.

Thermowood can be painted, stained, sanded, and treated just like other types of wood. Treating the wood can prolong its lifespan and bring out the raw beauty of the wood. Additionally, Thermowood comes in many cross-section profiles and sizes, so you can choose the best option to fit your needs and make your architectural vision an unparalleled reality.
