Sanded Plywood: Exterior grade. Excellent appearance, durability, and dimensional stability. Smooth face, excellent machinability. 4×8–1/4″, 3/8″.

Sheathing/Construction Plywood: JAY-K stocks both high-quality fir, and yellow pine plywood. Great for walls and roofs as well as general use, these exterior grade plywoods work great in a wide variety of applications. Fir plywood tends to be stiffer and more stable. Yellow pine is a great value and widely used. We have both in stock. Fir: 4×8–1/2″ 5 ply, 5/8″ 3/4″. Pine: 4×8–3/8″, 1/2″ 4 ply, 5/8″, 3/4″.

Underlayment: Fir, yellow pine, and AdvanTech available in stock. Generally tongue and groove (T&G), underlayment is the choice for a stiff, rigid, squeak-free floor.

AdvanTech flooring panels: High-performance structural panels engineered for more strength and stiffness to enhance floor performance. Builders say that AdvanTech makes your floors more solid and less likely to bounce. 50-year limited warranty. AdvanTech: 4×8–3/4″ T&G; Fir: 4×8–3/4″ T&G; Pine 4×8–3/4″ T&G; 1/2″ square edge.

AdvanTech ZIP Panels: Zip System® roof and wall sheathing offers structural panels with built-in protective overlays that eliminate the need for housewrap or felt forever. Simply install the panels, tape the seams with the specially designed ZIP™ System tape, and you’re done.

AdvanTech Sheathing Panels: In addition to AdvanTech Underlayment, we also stock AdvanTech sheathing panels. AdvanTech provides superior performance in walls or roofs. 4×8 1/2″ square edge, and 5/8″ T&G.

OSB (Oriented Strand Board): Commonly used in all types of construction. This isn’t old-fashioned “waferboard”—OSB is an engineered panel designed to be a plywood substitute. 4×8–7/16″.

Hardwood Plywood: Top grade birch, oak, and knotty pine in stock. We’ll cut to your size, and only sell you what you need, so if you don’t need a full sheet, you don’t pay for it. 1/4″, 1/2″, 3/4″.
