General information on awning covers

Protective awning covers are technical fabrics that are intended to be decorative along with their functional task. Awning covers are high performance products that meet with strict technical requirements.

Each production undergoes extensive laboratory tests.

Certain appearances in the cover are sometimes subjects of complaint but even by today’s standards they cannot be completely excluded:

Bending folds
Occur during manufacture and when the cover is folded. A dark line can become visible in back light particularly in the case of light colours.

3456
Waviness in the seam and length area
can occur in the side seams, in the vicinity of the seams and in the centre of the lengths. The cover is laid double on the seams. This results in different rolling diameters.

The tension that arises due to the folding arms and the drooping of the roller tube and/or the front profile can promote these effects. Waviness can form if a water pocket forms during strong rain. Requirements such as waterproofness, rigidity, dirt and water repellent properties, tearing and breaking strength, colour fastness and many other properties are determined, measured and guaranteed for each cover by the weaver. Although only first class examined cloth is used in manufacture, perfection has limits.

Waterproofness/resistance to rain
Polyacrylic sun protection fabric is impregnated with a water-resistant finish and remains resistant to rain during a short, light shower of rain with good care and a pitch angle of at least 14°. During longer periods and/or heavy rainfall the awning must remain closed or rolled up in order to avoid damage. Should the cover have become wet the awning must be extended for drying at a later time.

7
Stretching of the side lengths
The cover is usually kept permanently taut using an active spring system. Seams and hems have a reinforcing effect but must also take the most strain. When the cover is rolled up the hems and seams lay on top of one another, this increases the pressure and tension even more. Seams and hems are pressed flat and increase in length. When the awning is moved out this can lead to the side seams hanging down slightly.

Please see the Markilux, Weinor, Gibus or Paraflex fabric pages for more specific information.
