Clear Tarpaulin Guide: Uses, GSM Ratings & Where to Buy in the UK
A clear tarpaulin does something no other cover can — it protects while letting light through. Whether you're covering a greenhouse, enclosing a patio, protecting a market stall display, or creating a temporary conservatory, a transparent tarpaulin is the professional solution. This guide from Tarpaulins UK covers everything: GSM ratings, the best uses, what to avoid, and how to choose.
What Is a Clear Tarpaulin?
A clear tarpaulin is a transparent or near-transparent waterproof cover made from clear polyethylene (PE) or PVC film. Unlike standard coloured tarpaulins, a clear tarp allows daylight to pass through while still providing 100% waterproof protection against rain and wind. They're essential wherever visibility or light transmission matters.
Best Uses for Clear Tarpaulins
Greenhouses & Growing Tunnels
A clear tarpaulin is ideal for temporary greenhouses, polytunnel repairs, cold frame covers, and seedling protection. The transparent material allows full UV and visible light transmission — critical for plant growth — while keeping rain and frost off tender plants. For this use, choose a minimum 100gsm UV-stabilised clear tarpaulin sheet.
Patio & Outdoor Enclosures
Enclosing a patio, pergola, or outdoor seating area with a clear tarpaulin creates a weatherproof outdoor living space without blocking the view or light. Restaurants, pubs, and homeowners across the UK use clear tarpaulins to extend their outdoor season into autumn and winter. Our clear tarpaulin range includes versions with reinforced edges for permanent suspension.
Market Stall & Exhibition Displays
Market traders need weather protection that doesn't obscure merchandise. A clear tarpaulin front sheet keeps rain off display goods while customers can still see products clearly. The "glass clear" finish of our 100gsm transparent tarpaulin is the preferred choice for professional market traders across the UK.
Construction Site Windows & Temporary Enclosures
When installing windows or glazing on a construction site, a clear transparent tarpaulin over the opening maintains weather protection while allowing natural light into the interior. Far better than opaque covers for internal work.
Pool & Pond Covers
A clear tarpaulin used as a pool or pond cover allows light penetration (important for aquatic plants and fish) while keeping debris, leaves, and rain out.

Clear PVC vs Clear PE Tarpaulin
The two main materials for clear tarpaulins are:
- Clear PE (polyethylene) — lightweight, lower cost, good for seasonal use. Less durable than PVC but sufficient for most domestic applications. Our standard clear tarpaulin range.
- Clear PVC — heavier, more durable, excellent clarity, remains flexible in cold temperatures. The professional choice for permanent patio enclosures and commercial applications. Higher cost but significantly longer lifespan.
How to Fix a Clear Tarpaulin
Fixing options for clear tarpaulin sheets:
- Eyelets — all our clear tarpaulins come with reinforced eyelets for rope or bungee attachment
- Bungee cords — quick and easy for temporary installations, especially market stalls
- Zip ties — for fixing to pergola frames and greenhouse structures
- Tarpaulin clips — available from our accessories range for edge-grip fixing without eyelets
FAQs About Clear Tarpaulins
Q: Is a clear tarpaulin truly transparent?
A: Our 100gsm clear tarpaulin has excellent "glass clear" transparency — ideal for display use. Heavier weights have slight inherent haze but are still highly translucent.
Q: Will a clear tarpaulin let UV through for plants?
A: Yes. Our standard clear PE tarpaulin sheets allow UV transmission — suitable for most plants. Some specialist UV-blocking clear films are available for applications where UV exposure needs to be limited.
Q: How do I clean a clear tarpaulin?
A: Wipe with a soft cloth and mild soapy water. Avoid abrasive cleaners which scratch the surface and reduce transparency. Rinse thoroughly and allow to dry before storage.
