Best Materials for Outdoor Signs in Harsh Weather

Outdoor signage isn’t just about design. It’s about durability.

In Metro Vancouver’s climate, signs face constant rain, damp winters, UV exposure, and strong winds.

The wrong material can mean fading graphics, peeling edges, and costly reprints.

Here are the best large-format printable materials for outdoor signage that hold up in tough conditions and how to choose the right one for your project.

1. Weatherproof Vinyl (Cast & Calendered)

Vinyl is the go-to material for outdoor large-format printing. Cast vinyl lasts 5–7 years outdoors, while calendered vinyl is a more affordable option for short-term signage.

Vinyl rolls and large-format printing equipment in a signage workshop, used for creating window graphics, wall wraps, and outdoor promotional signage.

Best for: Window graphics, wall wraps, outdoor promotional signage.

Example: In our BC Liquor retail graphics rollout, we used high-performance vinyl films to keep branding consistent across dozens of locations.

2. Banner Vinyl (PVC)

Vinyl banner stock is flexible, lightweight, and easy to hang with grommets. With proper finishing, banners can withstand rain and wind.

Best for: Temporary outdoor promotions, event signage, fence wraps.

Tip: Use mesh banner vinyl in windy locations to reduce tearing.

3. Coroplast (Corrugated Plastic)

Coroplast is a lightweight, inexpensive option for short-term outdoor signs. While not as long-lasting as aluminum, it’s waterproof and easy to print on.

Best for: Real estate signs, lawn signs, temporary event signage.

Note: Works best for campaigns or installs under 12 months.

4. Dibond / Aluminum Composite Panels (ACP)

Dibond (aluminum composite) is a rigid panel with a plastic core sandwiched between two thin aluminum sheets. It’s lightweight, rust-proof, and holds up well outdoors.

Best for: Long-term outdoor signage, building-mounted graphics, wayfinding panels.

5. Adhesive Window & Wall Films

Specialized outdoor-rated films can be applied to glass, concrete, or painted walls. They’re removable, which makes them ideal for property managers and landlords with strict signage rules.

Best for: Storefront windows, branded entryways, mall exteriors.

Example: At corporate events, we use adhesive films to transform spaces quickly while ensuring easy removal after the event.

Conclusion

Outdoor signs live or die by the materials they’re made from. In Metro Vancouver’s weather, high-performance vinyls, banner stock, coroplast, aluminum composite, and adhesive films are the most reliable options.
