Background information:
Initially the swimming pool was only used for summer. The objective was to use it also in winter, taking advantage of the solar energy to heat a small covered part.

Objectives of the roof:
- Design with minimum air volume for heating
- Allowing entrance of natural light and solar radiation
- Rain protection
- Easy installation of the membrane

The cover is made of translucent PVC-polyester membrane, tightened on the supporting structure. The main structure consists of tri-articulated arches, made of laminated wood. The arches have a span of 12 m and are placed at a distance of 4.5m.
With this solution, the use of a detachable cover was possible on a wooden frame. The wood was a good choice within the natural landscape.

Reasons for choosing a prestressed pvc membrane:
It complies with all the objectives, specially the fact that the membrane can be removed in summer.

The roof is generated with elliptical arches to obtain the minimum air volume to be heated.

The tension in the membranes is obtained by a cord, which tensions the canvas to the structure.

Building process:
After installing and anchoring the structure, the membranes were assembled in one day.

The structure is made of laminated wood arches. The membranes are made of threaded polyester PES HT 1100dtex, 5x5 threads per cm (12 threads per inch) with transparent PVC coating, a weight of 800gr/m2 (230oz/sqyd) and a breaking load limit of 30daN/cm (167lbs/inch).
