Pro's & Con's for the use of PVC coated fabrics vs opal multiwall polycarbonate

Although many clients have a perceived preference for Polycarbonate over FR PVC “Clovis Canopies” give a 10 years warranty against premature UV degradation on both FR PVC and Polycarbonate, therefore the following “Pro’s & Con’s” may help decision making.

PVC Coated Fabrics

Pros:-

  • Considerably more cost-effective on the initial outlay.
  • As there is less structure within the roof area (purlin rails & glazing bars) this gives a less busy appearance.
  • When raining the noise within the canopy is softer (akin to being in a tent).
  • If the outside of the roof is dirty (although periodical cleaning is recommended) the canopy will still appear clean from within.
  • Lower solar gain (heat increase) within canopy on sunny days.

Cons:-

  • A slight reduction in light levels within the canopy.
  • Although very durable, if damaged repair is slightly more involved.
  • Life expectancy is shorter than polycarbonate although in excess of 14/15 years is common.
  • Because this is a single skin you may experience condensation dripping in cold and damp winter conditions.
Structured Opal Polycarbonate

Pros:-

  • Light levels within the canopy are higher.
  • Life expectancy is longer than with FR PVC.
  • Can be installed as a “man safe” roof for impact, although all rooves should be considered fragile.
  • Less condensation in the winter months.
  • If damaged, individual sheets can be easily replaced.

Cons:-

  • Initial costs are considerably higher than FR PVC.
  • As light levels are higher if the roof is dirty outside this will be visible within the canopy.
  • Higher noise levels within the canopy in rainy conditions.
  • Slightly higher solar gain (heat increase) within canopy on sunny days.

In summary, the decision made will revolve around budgets and perceived preferences however whatever choice is made your canopy will give many years of durable service.
