Below you'll get some advice on how to deal with your awning fabric.

Expand/CollapseAssembly of fabrics

Commonly multiple panels are seamed together when confecting an awning fabric. The maximum width of a panel depends on the type of fabric, e.g. acrylic, polyesters or screens. Acrylic panels have a maximum width of 120 cm.

The production of an awning fabric starts off with cutting the panels to the appropriate length. Illuminated workbenches allow identifying flaws in weaving. Then the separate panels are seamed together by a fully-automated sewing machine.

The top and bottom end of awning fabrics are hemstitched. Hemstitches are required in order to clamp the fabric onto the awning later on.

Even though the entire production is mainly performed by modern sewing machines, the high quality of fabrics used in the assembly of VARISOL awnings strongly depends on the skills and experiences of our suppliers.

Expand/CollapseProperties of fabrics - important notes

Awning fabrics have to answer functional as well as decorative purposes. Even though fabrics have to pass through several quality checks, we can't guarantee that the final product will be ultimately perfect.

There is a number of visual effects, which can't be entirely eliminated. However, those effects do not alter the value and/or functionality of an awning. Hence, they do not justify complaints about the quality of an awning fabric.

Below you can find an overview of the most common visual effects that may occur.

    Wrinkles may arise during the processes of confecting and shipping an awning fabric. At the spot of a wrinkle colours may appear to be darker. This effect is even greater on light-coloured fabrics.

    Since hems and seams are doubled, the fabric does have differing diameters when being rolled up on a roller tube. The effect is even enhanced due to inevitable sags of the roller tube and other components.
Waviness due to differing diameters
    In order to make fabrics waterproof, they are coated with a waterproof finish. That is why awning fabrics remain watertight, if mounted with an inclination angle greater than 14°.
    In pouring rain, the awning has to be retracted so as to protect the fabric from unnecessary wetness. If the fabric got soaked, the awning has to be extended so that the fabric can sun-cure.

    The tenseness of an awning fabric is commonly achieved through torsion springs. Hems and seams do act as an enhancement of the fabric, but also have to carry the highest load. When being rolled up, hems and seams are squeezed and hence they elongate. As a result side hems are likely to sag.

Expand/CollapseRecommendations on cleaning and maintaining awning fabrics

Awning fabrics have to be cleaned and maintained periodically. This includes that pollution on the fabric's surface and minor spots have to be removed.

Caution: Awning fabrics are not suitable for laundry!


Loose dirt must be removed from the awning cloth first. To increase the cleaning effect, the awning fabric should be moistened with clear, pure water using a garden hose. This will easily dissolve heavily encrusted dirt particles and make it easier to remove them. Then remove the loosened dirt particles by additonal spraying. Do not brush stains dry, as there is a danger of the dirt rubbing into the fibre and the spaces between the fibres. Do not use high-pressure cleaners for cleaning, as there is a danger of damaging the seam and material. 

Cleaning procedure

General soiling or even light stains can be treated with an approx. 5-10% dissolution of mild detergent and warm water (max.40°C). Foam up cleaning solution by dipping and squeezing out a sponge and apply as foam to the dirt spots/stains. Then allow the foam to act for approx. 15-20 minutes and rinse off with plenty of fresh water. Repeat this procedure until the dirt or light stains have been completely removed. 

Stubborn stains have to be soaked with the prepared solution and the solution has to remain on the fabric for about 15-20 minutes. Please repeat this step until all major pollution has been removed.

Attention: Strong friction with hard brushes or sponges can lead to roughening or damage of the awning cloth!


After-Treatment with plenty of fresh water is absolutely necessary in order to remove all components of the cleaning agent. The better the after-cleaning and thus the removal of the cleaning agent used, the lower the Degradation of the water-repellent properties of an awning cloth. 


If the water-repellent quality of an awning fabric decreases as a result of cleaning, the weather protection and beading effect can be restored by re-impregnation, depending on the type of fabric.

General Info

Any type of cleaning of an awning fabric carried out with the aid of cleaning agents can lead to a degradation of the original protective function of the fabric. Therefore, from the manufacturer's point of view, it is necessary to impregnate the awning fabric after a selective or extensive cleaning in order to provide the treated awning fabric with sufficient weather protection again.

Due to the wide range of impregnating agents and different types of fabric, no recommendations can be given for special products. When selecting the impregnating agent, care should be taken to ensure that it is suitable for textiles.

In the course of environmental protection, it should be noted that only water-soluble impregnating agents - for the sake of the environment - are used. The manufacturer's warning and instructions for use must also be strictly observed, as impregnating agents can cause skin and eye irritation.
