Plywood

Plywood is one of the more widely used wood panel products in use today. Manufactured from thin wood veneers that are layered perpendicular to each other and bonded with strong adhesives under heat and pressure. The result is a graded, dimensionally stable panel with an excellent strength-to-weight ratio that can be used for a wide range of building applications, including subflooring, sheathing and shear walls.

CDX Plywood stack

CDX Plywood

A standard used in construction, we stock CDX plywood in a wide range of thickness and panel sizes. CDX is a grade of plywood where the facing surface is rated C, the back surface is rated D and exterior glue is used. Applications include sheathing, roofing and underlayment.

CDX Plywood

CDX Square Edge, STR 1 3/8" 4x8, 4x9, 4x10
CDX Square Edge, STR 1 1/2" 4x8, 4x9, 4x10, 4x12

T&G Pressure treated plywood stored at our High Street yard

Pressure Treated Plywood

Pressure treated CDX plywood is treated with Preserve CA-C, a treatment that extends the life of the wood and provides long-term protection against rot, fungal decay and insect attack.

Pressure Treated Plywood

CDX PT 1/2", 5/8", 3/4" 4x8
Sturd-I-Floor T&G PT 3/4", 1-1/8" 4x8

PT = Pressure Treated

Preserve CA-C is seen as a “greener” preservative and a more sustainable option than previous wood preservatives.

Fire retardant plywood treated with Pyro-Guard

Fire Retardant Plywood

Plywood treated with Pyro-Guard fire retardant has a low combustion rate and unlike a painted on coating is pressure impregnated deep into the wood to provide long lasting protection. When exposed to fire, non-combustible gas and water vapor are produced, and a layer of protective char forms, which limits combustion and insulates the wood from further damage.

Fire Retardant Plywood

CDX Fire Retardant 1/2", 5/8", 3/4" 4x8
ACX Fire Retardant 3/4" 4x8

The workers of the plywood company stand on top of one of their plywood sheets while spanning seven feet over a briefcase
In 1905, one Gustav Carlson, part owner / manager of a small wooden box company decided to laminate wood panels using paint brushes and house jacks for presses. Called “3-ply veneer work”, it wasn’t long before door, cabinet and trunk manufacturers took notice and placed orders. Within two years the company had automatic glue spreaders and a sectional hand press, producing up to 420 panels of plywood a day.
