Yes, to most tent people, the idea of acrylic canvas, sounds strange and unnatural, on these beautiful, traditional nomadic structures. But, the truth is, of course, that to make cotton and polycotton able to withstand the elements in a European climate, various chemical products need to be applied. Don’t worry, all have passed safety tests.
If you have lived in or worked with canvas, you are well aware of the black spot mould which appears and the inevitable deterioration of the fabric. We recommend, every year, to clean the canvas with a soft brush and mild detergent and then to reproof the canvas with a reproofing solution (we can supply a paint-on FWR (flame, water and rot-proofed) solution). Acrylic canvas, however, doesn’t rot.
8 years ago we made this yurt cover for Tithe Farm B&B in Lincolnshire, England. They chose to have acrylic canvas, rather than the usual cotton canvas we were working with at that time, for longevity.
After standing outside for 8 years in Britain (to quote Biff Vernon, the yurt owner): “The fabric is still completely waterproof. The only problem we had was that where the six ropes that hold the top star down rub on the canvas at the roof/wall angle little holes have been worn. We stuck patches on with fabric glue to reinforce these and wrapped the ropes in a fabric sleeve to reduce the pressure. That might be less of a problem with curved roof poles but ours are straight so there’s quite a sharp angle”. (This issue can be prevented by threading a small piece of clear plastic hosepipe onto the star ropes, to sit on this shoulder of the roof rafter).
(Guess which is new and which is 8 years later).
A more natural fabric like cotton or even polycotton would have well perished long ago in these conditions. The synthetic fabrics are woven and look very much the polycotton, only hang a bit more stiffly.
These fabrics were PU coated, but we are now working with a FWR (flame, water and rot-proofed), fabric in which the proofing is in the fibres themselves, so is permanent, and can’t be removed.
Acrylic canvas is expensive, and not for everyone, but weighing up all the odds and external conditions, may be worth the investment, especially for a more upmarket look.
