Sun damages - deformation of the profiles


Attention! Swimming pool covers made of PVC, in particular of the Solar type, must never be exposed to the sun in the dry state and should not be operated without the protective covering. In particular, ensure that the profiles always have contact with the water surface, or are protected from the sun.



If PVC profiles have been exposed to the sun, without contact to the water surface the following damages are visible:


  • Deformation of cover
  • Shortening of cover
  • Cover looks milky
  • The cover has expanded on the lower and / or upper side
  • The profile connections have opened so far that they no longer hold together
Hail damages - Mechanical damages


Attention! Damage to the installation can arise of different reasons. In the case of damage to the system, the system must be immediately shut down and the responsible dealer must be contacted. Have your system repaired only by qualified personnel and only with original spare parts.












Hail damage
Some of our products are hail class certified. Rollo Solar's manufacturing guarantee covers material damage on your swimming pool cover if the hail grain size is within the hail class * of the product has not been exceeded. The owner has to report the hail damage immediately to the responsible dealer / manufacturer and has to provide the local weather authority with a written proof of the respective hail grain size.

The hail class can be found by your dealer, in the operating instructions (from 11/2016) or online under the Hagelregister.


Attention! This value applies only to new materials. The hail resistance can diminish within a few years as a result of natural weathering.


Color changes / wood components / plastics


The aging of our plastic products depends to a great extent on the prevailing operating and ambient conditions, color changes due to UV-content in the
Daylight and natural weathering are unavoidable. These aging phenomena will be seen in our covers over time, including yellowing and aging (photooxidation, embrittlement) etc. Special ingredients and stabilizers in our profiles can only delay, but not prevent, these circumstances of aging. These are no manufacturing errors and no grounds for complaints.


Wooden components
The wood selection of our products takes place according to the typical requirements exactly as their further processing. The result of this process are woods of individual structure and beauty. Adorned branches with dry cracks, irregularities in the grain, color nuances and deviations of the colors depending on the direction of sight belong to the special character of the natural product wood. There are no manufacturing errors. Wood continues to live after processing. It swells and shrinks through moisture absorption and through moisture release. These circumstances will be seen over time. Gaps will change, thickness will change. Wood can change in time and color. It is an eternal process. Special ingredients in our wood preservatives can only delay this process, direct exposure to the sun accelerates this process.


Attention! Direct light exposure due to sunlight or strong artificial light changes every material. For this reason, e.g. in the case of a deck mounted installation, the claddings should not permanently be covered with decorations etc.


Attention! Please avoid placing radiators, radiant heaters or other sources of heat near our facilities. Depending on the type of wood, there is a different resistance. A real wood surface must always be treated carefully, the surface must be protected against mechanical stress in order to prevent scratches.


Attention! Alle wooden components are no barefoot floorboards.


Condensation in the profiles

The residual moisture contained in the hollow chambers of the profiles during production is reflected by condensation on the inside of the hollow chambers by temperature differences. This does not affect the functionality of the swimming pool cover. Condensate formation within the profiles is visible on all profiles with transparent and semitransparent surfaces and is not a manufacturing defect and does not constitute a claim for reimbursement or warranty.
