Composite Cladding and Exterior Slat Wall Panels

The fluted, slatted look your architect drew. In stock in Fairfield, NJ and Framingham, MA.

 

Slat walls are on half the drawings you see now: storefronts, entries, rooftop decks, privacy walls. Real wood slats look great for a season, then they need oil, then they gray, then they check.

 

Norm Supply stocks WPC outdoor slat wall panels that give you the same deep-groove look in a composite board. No stain, no sealer. Same-day pickup in Fairfield when it's in stock, pickup in Framingham when you call ahead, freight shipping nationwide, and samples are free.

 

Call Fairfield at (929) 323-9333 or Framingham at (516) 912-7893, or request panel pricing online.

 

What these panels are

A WPC (wood-plastic composite) slat wall panel is a single board with deep grooves in the face. Install a run of them and you get a fluted, slatted wall without cutting and spacing individual battens.

 

Our customers call them a lot of things: WPC panels, composite cladding, slat wall, fluted panel, WPC wall panel. Same product.

 

  • Weather resistant. Made for rain, snow and sun on exterior walls.

  • Low maintenance. No painting, staining or sealing.

  • Rot and pest resistant. Won't rot or attract termites like untreated wood.

  • Stable. Made to resist warping and cracking.

  • Clean finish. A hidden-fastener system means no face screws on the wall.

  • Horizontal or vertical. Run the slats either way to change the look of the elevation.

Commercial exteriors. Storefronts, offices, restaurants and hospitality projects where the architect wants warmth without the upkeep.

 

Mixed with siding. Run our WPC composite siding on the main walls and slat panels on the accent. Add black aluminum railing and WPC deck boards and the whole exterior comes off one order.

 

Want the slatted look indoors too? We also stock interior acoustic slat panels, 2 ft × 9 ft.

 

Your 3-step plan

1. Send the wall. Elevations, dimensions, photos, the look you're after. A sketch with a tape measure in the photo works.

 

2. Get your panel count and pricing. We work out the quantity with you and send contractor pricing. Samples are free by mail or pickup.

 

3. Pick up or ship. Same-day pickup in Fairfield when it's in stock, pickup in Framingham when you call ahead, or we book a freight carrier to your jobsite.

 

You install. We supply. Norm Supply sells materials only.

FAQ

What is a WPC slat wall panel?

It's an exterior wall panel made from wood-plastic composite with deep grooves in the face. Installed side by side, the panels create a slatted or fluted wall without individual battens.

 

What size are your outdoor wall panels?

Each panel is 8 in wide and 9.5 ft long.

 

Is composite cladding the same as composite siding?

They're close cousins. Our composite siding is a 12 ft by 6 in board with lap, shiplap or flat profiles. The slat wall panel is a 9.5 ft by 8 in board with a deep slatted face for a fluted look. Many jobs use both.

 

Can the panels go vertical?

Yes. You can run the slats horizontally or vertically.

 

Do the panels need painting or sealing?

No. WPC slat panels don't need painting, staining or sealing.

 

Do you install wall panels?

No. Norm Supply supplies materials only. Your crew or installer handles the installation.

 

Can I get samples?

Yes. Free samples by mail or pickup.

 

Is there a warranty?

Yes. Our outdoor wall panels carry a 15-year limited warranty.

 

Got a feature wall on the drawings?

Send the elevations. We'll send back panel counts and pricing.
