This is the square polyester sail we supply for caravans and patios, and the square is the shape that suits a caravan awning line because it runs true down the side of a van where a triangle would leave a gap. The cloth is a solid polyester rather than a knitted mesh, so it sheds rain as well as sun and the area under it stays usable when the weather turns. It is cut to the span and finished with stitched seams and corner fixings, so it can be strained tight on the van, on a frame or between two walls.
A square sail runs true along the side of a van where a triangle leaves a gap at one end. That is the case this cover is supplied for. It is a solid polyester cloth rather than a knitted mesh, so it sheds rain as well as sun, and it is cut to the span with stitched seams and corner fixings so it can be strained tight on the van or on a frame at the pitch.

A caravan awning line is a long straight run, and a square covers it end to end while a triangle shades one corner and leaves the other exposed. Because the cloth is a solid polyester, it also keeps the rain off the seating area rather than letting it through, which matters when the space under the sail is where people sit. The shade rate is made to order, so the cover can be set to the pitch, and the seams are stitched rather than welded so the sail can be folded and taken down without cracking along the join.

The sail is used along a caravan side, over a balcony or a terrace, and across a patio between two walls. Because it is a solid cloth it is also the grade chosen where the cover has to keep water off as well as light, rather than only shading. Households covering beds under a mesh cover often pair it with a planting bag, and the wider shade net range covers the knitted and reflective types where an open cover is the better answer.

On a solid cloth the seam and the corner take the whole load, so the panels are stitched and the corners are reinforced rather than the cloth being punched through. That is what lets the sail be strained hard on the van or between walls without the seam opening up, and it can be taken down, folded and put back up season after season. A knitted monofilament net covers the shading job where an open weave is wanted, while this sail covers the weatherproof square span.

Span, shape, shade rate and colour are all made to order, so the first detail to confirm is the points you are rigging to and the area under them. Sails ship in export packing and are folded to suit the size. Buyers tracking how tensioned sails perform on caravans and terraces can follow trade coverage such as HortiDaily and FreshPlaza for what is being installed.
Will it keep the rain off?
Yes. It is a solid polyester cloth rather than a knitted mesh, so it sheds water as well as shading, which is why it suits a caravan seating area or a terrace.
Square or triangle for a caravan?
Square for a straight run along the side of a van, since a triangle leaves one end uncovered. A triangle is the better shape over a single corner.
Can I order a different size, shape or colour?
Yes. Span, shape, shade rate and colour are all made to order. Tell us the points you are rigging to and we will advise.
