Thermally Modified Wood Collection

The UFP-Edge Thermally Modified Wood Collection is wood cladding of the future. This beautifully stable wood cladding is made from an innovative thermal modification process which stabilizes the wood naturally with heat and steam. This process makes the wood less vulnerable to shrinking and seasonal expansion and contraction. What’s more, it resists rot and insects for long-term performance. 

Our thermally modified wood cladding will give your home great curb appeal. The cladding comes in natural or a variety of on-trend prefinished colors. The tongue and groove interlocking pattern allows for easy installation on interior walls and ceilings and exterior siding applications.

Frequently Asked Questions

Thermally Modified FAQS

Are there any harmful chemicals used in the thermal modification process?

No. The thermal modification is done in a control environment and is cured out by the time products are handled for installation.

Is thermally modified wood resistant to rot, termites and other insects?

Yes. Thermally modified wood is more resistant to rot, termites and other insects than non-thermally modified wood.

Will the thermally modified wood expand and contract?

Expansion and contraction are greatly minimized through the thermal modification process. Slight movement can still occur, but it is significantly less than untreated wood.

Should I pre-drill holes for fasteners?

Yes. Predrilling holes for fasteners is recommended. Areas especially prone to cracking such as the ends of the boards should always be predrilled. The thermal modification process makes the wood slightly more brittle and therefore can be more prone to splitting.

How long will the prefinished color last?

Thermally Modified Wood Collection cladding is prefinished in a controlled setting with a proprietary two-coat exterior coating. Over time the finish will require some maintenance/refinishing. Depending on the application and the amount of UV exposure, refinishing/maintenance may be needed within a few years. However, if the cladding is not exposed to direct UV light the finish may last several years with minimal wood maintenance upkeep.
