The short answer
Use PVC blockout for indoor banners, short-term outdoor banners, anything fixed flat against a wall, anything you want to look bright and saturated, and anything where you don't want to see what's behind it.
Use mesh for any outdoor banner exposed to wind for more than a day or two — scaffold wraps, hoarding banners on open sites, sports-club perimeter banners and anything bigger than about 3 m × 2 m fixed in the open.
Use fabric for high-end indoor banners and exhibition backdrops where you want a soft, premium finish with no glare under spotlights.
The rest of this article is what to consider when the answer isn't obvious.
What each material actually is
PVC blockout is a coated PVC sheet, typically 440–510 gsm for general signage use. The "blockout" refers to a grey inner layer that stops light passing through. Print sits on the smooth white outer surface. Colours come out bright and saturated. Stiff enough to hold its shape, flexible enough to roll for transport. The standard high-street banner material.
PVC mesh is the same family of material but with holes — typically around 30–40% of the surface area is open. The wind passes straight through, so the banner doesn't load up the fixings or tear itself off the wall. Print quality is slightly softer than blockout because each thread of the mesh holds a little less ink than a solid surface. From normal viewing distance (anywhere past 5 m or so), the difference is not noticeable.
Fabric is a polyester display textile — sometimes called "display silk" or "Samba". Lightweight, matt finish, no glare. Sewn pockets at the top and bottom for pole or frame fixing. Premium feel; not suitable for outdoor use long-term.
When wind matters — and how much
A solid PVC banner of any meaningful size will act as a sail. A 6 m × 3 m PVC banner fixed flat against a scaffold in a 40 mph gust generates several hundred kilograms of wind load on the fixings — and several hundred kilograms more at the corners where the banner tries to lift. Cheap fixings will fail. Even good fixings can rip the corner of the banner clean off.
The standard fixes are:
- Wind slits. Half-moon cuts in the banner that let wind pass through. Effective on smaller banners; cosmetic only on very large spans.
- Mesh. The proper fix for any banner that will live outdoors more than a few weeks. The wind passes through the holes; nothing loads up.
As a rough rule:
- Indoor or short-term outdoor, any size up to about 4 m × 2 m — PVC blockout, hemmed and eyeleted.
- Outdoor, any size, exposed to wind, longer than two weeks — mesh, hemmed and eyeleted.
- Outdoor, very large (above 6 m on one side), exposed to wind — mesh, full stop.
- Anything attached to a scaffold or hoarding for a six-month build — mesh.
Hems, eyelets, pole pockets
Hemmed and eyeleted is the standard finish. The edge of the banner is folded back and welded for strength, and brass eyelets are punched every 500 mm to 750 mm around the perimeter for cable-tie or bungee fixing. Suits 95% of jobs.
Pole pockets — sewn sleeves top and bottom into which a pole slides — are used for hanging banners (from a ceiling, from a stand) and for outdoor banners that need to stay taut between two fixed points. More expensive than eyelets but the right answer for some installs.
Rope edges — a sewn rope into the hem — give you a continuous load-bearing edge instead of point loads at each eyelet. Used on very large mesh banners and on heavy-duty stage backdrops.
How long should an outdoor banner last?
A reasonably well-fitted PVC banner with latex-printed graphics will look good for 1–2 years outdoors before colours noticeably fade and the corners start to tire.
A mesh banner in the same conditions will look good for 2–3 years, partly because wind isn't constantly stressing the corners.
A laminated PVC banner (clear protective film over the print) can stretch outdoor life to 3–4 years, but at that point the fixings are usually the weak link, not the print.
If your banner needs to last longer than four years outdoors, you're really looking at a printed rigid panel or hoarding board, not a banner.
What we'd suggest for common Somerset jobs
- Shop "Now Open" banner, fixed flat to a fascia for a fortnight: PVC blockout, hemmed and eyeleted. From £85.
- Construction site hoarding wrap, 6 m × 3 m, on the perimeter for six months: mesh, hemmed and eyeleted, with extra eyelets every 500 mm. Discuss the fixing method with the site team before we quote.
- Scaffold wrap over a refurb on a Bath or Bristol shopfront: mesh, sized to the scaffold bay, fixed with bungee. Often paired with a printed lower hoarding panel at street level.
- Sports-club perimeter banners for a Somerset football or rugby ground: mesh, hemmed and eyeleted, in branded sponsor-pack sizes (usually 2 m × 1 m or 3 m × 1 m).
- Indoor event banner behind a stage or at a trade show: fabric with sewn pole pockets — best finish, no glare under spotlights.
- Outdoor festival or village fete banner for a weekend: PVC blockout, hemmed and eyeleted, with wind slits if the weather forecast looks unfriendly.
