Timber treatment

Treated to reduce weight, and stand the test of time

At our timber manufacturing centre, we can kiln dry wood to reduce its weight, and reduce moisture levels by up to 80%, or we can apply heat treatment to comply with ISPM15 worldwide transport regulations.

“Having worked with Tri-Wall for a number of years now, they are great to work with and always reliable”

John Richardson
Barbour & Sons

“Tri-Wall does all of our VCA certification and HSE negotiation. Such a strong relationship with HSE means we’re able to push through packaging for international, which is really vital to our business.”

Tri-Wall customer

“We have a unique set-up. We have a huge amount of material stored at a 3rd party warehouse. With very little space on site, we rely on Tri-Wall for daily deliveries, with up to 4 deliveries per day. If we had an unreliable supplier and they missed one day, it could shut down the entire plant.”
