We utilize 100% domestic hardwood lumber species white ash & red oak largely because of their natural grain & character. Nusku Thermacor is a perfect example of our company highlighting the value & beauty of natural wood products.

PROCESS

DAY 730

Over a 2 year timeframe,  Nusku Thermacor material will naturally transition to a gray tone. This process does not impact the performance of the decking & original color can be restored with refinishing process.

Nusku Thermacor typically fits a more modern architectural style

with the color, grain and installation options

MOISTURE EXPOSURE

When natural wood products are exposure to rain, snow or moisture the extractives, including natural pigments can bleed out which in turn can lighten the color of the wood.

UV EXPOSURE

When Nusku Thermacor is installed exterior, the greatest impact to silvering out is ultraviolet rays. UV rays are responsible for breaking down lignin in natural wood products which in time transitions the fiber to silvery-gray. 

INSTALLATION OPTIONS

Nusku Thermacor can be installed with a more traditional option utilizing screws, but when a clean finish without seeing hardware is desired our customers install with a variety of hidden clip options. There are a wide range of hidden fasteners that work with the standard Thermacor profiles, but we highly suggest using the Exoclad & Exodeck hidden clips.
