Attachment
Screws through the panel? Yes! It is simple, do not compromise the strength and keep the membrane water proof



Keep it simple!
One of the main criterias, when we started out designing Coverfeeds®, was the whole attachment and installment problem. By analyzing the PVC vinyl fabrics used on most covers in the market, we used a lot of our membrane load and stretch experience from the sailmaking industry we are so familiar with and solved this with a simple chipboard screw.

The solution was to be simple, effective, low cost and only require existing familiar tools to be handled on any spot necessary in case of emergency repairs or retrofit.

Screws don't cut the structural yarns
By perforating the fabric with screws we do not actually cut over the yarns, but merely create a tiny hole in the water resistant membrane and thereby we do not reduce the strength of the textile at all.

On top, we have positioned at least two screws to go through the dense webbing of the keder, reinforcing the attachment from the loads of pulling ceilings over beams on ie. Clearspans.

Alternatively; If we had punched a hole and used ie. rivets or click solutions to assemble, we would have cut over a lot of yarns in a critical area with high loads, hence compromising the structural reliability essentially inviting damage to come by.

It can handle even the heavy pullers
We know membrane loads and with yachting sails and we are talking multiple tonnes in every corner. With tents it is 'only' still kilos or pounds since most still install ceilings by hand pulling from 2-3 persons across beams and Clearspans (OK, some use fork lifts or Oxes), essentially loading pressure with around 300 kilos at the most (in case they are all hanging freely in the air from the Coverfeed®).

Even the smallest of our models (KCF85) can take more than 600 kilos without breaking and our tests did'nt show permanent damage (wrinkles) to the textiles before 465 kilos, which is not standard loads.
