FAQs

Benchmark Series

WHAT KIND OF WOOD IS THIS? +
Thermally modified white ash and thermally modified Scots pine.
WHAT IS THE THERMAL MODIFICATION PROCESS? +
Heat and steam, no chemicals. This process gives the wood rot resistance, stability and beauty.
WHY IS THERMORY® THE PREMIUM MODIFIED WOOD BRAND? +
Thermory has over 20 years of experience thermally modifying wood. We’ve sold over 200 million sq. ft. world wide.
WILL IT FADE OR CAN I KEEP THE COLOR? +
Yes, it will fade - all wood products do - but this will not impact rot resistance or stability. Treat with Cutek Extreme, a penetrating oil (not a sealer) with colortoune to reflect the UV rays of the sun to allow the brown color to last longer, or allow to age naturally to a beautiful silver-gray. The aging process typically happens within 6 months.
ARE THERE ANY CHEMICALS? +
No, absolutely no chemicals - only heat and steam.
WHAT ARE JEM™ JOINTS? +
Machined ends that connect boards the long way. Every other brand of decking requires the ends of the boards to rest on joists except Thermory® white ash.
IS THERE A ROUTER BIT TO REPLICATE THE JEM™ JOINT ON SITE? +
No, this is too large of a joint to produce with a hand router. You will never need to, if the board is long enough to span 2 joists.
WHERE DO THE ASH AND PINE COME FROM? +
White ash is sourced from North America and northern Europe. Scots pine is sourced from Scandinavia.
WHAT IS THE BOTANICAL NAME AND JANKA HARDNESS? +
White ash (Fraxinus americana) has a janka hardness of 1320. Scots pine (Pinus sylvestris) has a janka hardness of 540.
WHAT COLORS IS IT AVAILABLE IN? +
The colors are the natural result of the thermal modification process. White ash is a rich exotic brown, and Scots pine is a lighter golden brown. Unoiled, both will naturally weather to grey over time. We have additional colors available in our Drift and Ignite line of cladding.
WHAT SPANS ARE REQUIRED FOR THERMORY? +
Perpendicular installations: support joists should be no more than 16” on center.
45º angle installations: support joists should be 12” on center.
WILL THE PACS™ GET BRITTLE WHEN IT’S COLD? +
No, these are made of polyomethylene (POM), one of the strongest plastics available.
CAN I USE THERMORY® WITH PACS™ FOR A DOCK? +
No, PaCS™ are not intended for docks. Waterfront applications are no problem with the PaCS™ as long as it’s not a dock.

IS THE BRUSHED SURFACE MORE LIKELY TO CAUSE SPLINTERS? +

DOES THE BRUSHING AFFECT THE DURABILITY? IS THERE ANY DURABILITY TESTING ON A BRUSHED PRODUCT? DOES THE BRUSHING MAKE IT MORE SUSCEPTIBLE TO DEVELOPING MOLD/FUNGUS? DOES IT AFFECT THE FIRE RESISTANCE? +
