Installation Tips

1. That depends on the product and the local regulations. A permit is usually not necessary for temporary placement. For (semi) permanent placements, it’s best to contact your municipality.

2. It’s necessary to tighten the roof fabric enough to avoid “hammocks” on the roof and also re-tighten once or twice again after a few months of use. This is important when assembly in cold weather (autumn and winter) because the fabric is stiff then and when we get the sun and warm weather afterward it will make the fabric “slack” again and need to be re-tightened before next winter.
