International Wood Products supplies decking, railing, siding and trim for homeowners and contractors building decks or remodeling an exterior. Its range includes Trex decking and railing alongside LP SmartSide siding and trim. You can compare materials for the deck and the house exterior within that range.
International Wood Products, or IWP, is an independent building-materials distributor. It’s been family-owned since 1995. Its assortment brings together products from separate suppliers, including Trex, LP and UFP-Edge.
Trex decking and railing
IWP distributes both Trex decking and railing. Plan them together because rail posts and attachments affect the framing underneath. A finished walking surface makes a poor time to discover you needed blocking underneath. Settle the stair layout and railing attachments before laying the decking.
LP SmartSide siding and trim
Siding and trim are part of IWP’s exterior range too. Its LP SmartSide offering includes both, with primed and ExpertFinish products. That lets you work through the wall covering, window surrounds and corners together. Plan the trim with the siding.
Primed siding leaves finish painting in your job plan, which matters when you’re figuring labor and the order of work. Include that painting work when comparing the primed and ExpertFinish options.
IWP also distributes fiber-cement siding and specialty wood products.
UFP-Edge primed trim
IWP’s trim lines include UFP-Edge Primed SPF with XTP and Premium Primed trim. XTP means exterior topical preservative. With primed trim, primer prepares the surface for a finish coat, so painting belongs in the job schedule. Account for exposed faces, cut ends and joints when planning that work.

Frequently Asked Questions
Does International Wood Products make the decking and siding it sells?
International Wood Products is an independent distributor, and Trex, LP and UFP-Edge are separate suppliers. When you’re comparing products, the individual supplier’s installation requirements matter, even when the materials come through the same distributor.
Can you get siding and trim together from International Wood Products?
International Wood Products distributes LP SmartSide siding and trim, including primed and ExpertFinish products. Plan the trim thickness before you settle the siding details, because it affects how the siding meets the trim around your windows and doors.
What does XTP mean on UFP-Edge trim?
XTP means exterior topical preservative on UFP-Edge Primed SPF trim. It’s a preservative designation, so you’ve still got finish painting to account for on this primed material.
Does International Wood Products offer custom wood profiles?
International Wood Products offers custom tongue-and-groove, shiplap and bevel milling through its Tumwater operation, along with pre-staining and pre-priming. If you’re matching existing woodwork, the profile name is only part of the match; the joint shape and exposed face width need to agree too.
