We have been big fans of the complete line of WindsorONE Protected trim boards for a long time.  In fact, this is the only primed pine trim board that we stock at our locations, so if you order “primed pine” you know that we are always going to deliver a quality product.

In 2006 WindsorONE released its WindsorONE Protected Trim Board line with a 30 year warranty against rot, insects and mold. WindsorONE Protected uses water, heat and borates to bond the 5 protective organics to the wood. This process gives full penetration protection through the entire board, making it durable for exterior applications. WindsorONE Protected also has a GOLD Indoor Air Quality rating, meaning it can also be used for interior applications without the fear of harmful off gassing.

WindsorONE Protected has been used for over 15 years on the exterior without a single warranty claim.

Make sure that the back of the board says “Protected”. If you are purchasing material from Kuiken Brothers, this is the only stamp that you will see in our inventory.

How Does It Work?

WindsorONE+ TRU-CORE Protected trim does not require preservative end re-treatment in the field, while LOSP treated wood requires end preservative re-treatment in the field.

Actives Delivered Deep into the Core

• The Tru-Core penetration technology takes five EPA registered decay and insect control preservatives and transports them to the core of the board, binding them to the wood fibers.

Tru-Core Penetrates Heartwood

• Tru-Core fully penetrates the heartwood of the board (unlike other outdated technologies). Heartwood typically makes up 30% of a board.

WindsorONE+Protected Trim & Pattern Boards feature a Gold IAQ rating which makes it suitable for interior use. Other generic trim boards may feature an outdated treatment done overseas to try to reduce expenses, resulting in off gassing of solvents, raising concerns for interior use safety and environmental protection.
