Roller shutter covers are used to cover the surface of the pool.

The use of a cover can drastically reduce heat loss. This in turn saves costs. An investment in a cover therefore pays for itself very quickly.

Another advantage of using a cover is the extension of the bathing season. As the pool retains the water temperature for longer when a cover is used, this extends the swimming season.

Advantages of a roller shutter cover at a glance:

  • Reduction of energy costs through insulation effect
  • Reduction of chemical consumption
  • Reduction of water consumption
  • Reduction of algae formation
  • Avoidance of soiling
  • Heat gain with solar profiles
  • Elimination of heat losses due to the effect of wind
  • Relief of the building through reduced evaporation in indoor swimming pools
  • Improved safety through increased accident protection


A basic distinction is made between 2 systems for roller shutter cover systems:

  • Above-ground systems are located outside the pool and are usually installed above the water level; they are easy to retrofit.
  • Underfloor systems are located in the basin and are generally below the water level; they are usually installed in new buildings.

The underfloor system stands out in comparison:

  • Suitable for practically all pool types
  • The most common variant for new buildings
  • Roller shutters out of sight
  • Cleaning advantage
  • Various shaft types possible
  • Aesthetically pleasing cladding variants that match the pool
  • Modern technology
  • Use of high-performance plastic for gentle running of profiles from various shaft types


There are different materials used for the cover profiles of roller shutter covers. These are usually PVC or polycarbonate.

Properties of PVC - polyvinyl chloride profiles are:

  • Temperature-resistant up to approx. 60 °C
  • acid-resistant
  • brine resistant
  • rot-resistant
  • relatively porous (adhesion of lime, soot, etc.)
  • relatively soft (flexible)
  • Comprehensive recycling system
  • UV-resistant
  • translucent in transparent versions
  • Colors vary depending on the manufacturer. For example, they are available in light blue, white, gray, light ivory, transparent black (solar), transparent
  • Commercially available cleaning agents can be used
  • favorable price

Properties of polycarbonate profiles are

  • Temperature-resistant up to approx. 120 °C
  • flame retardant
  • Extremely durable, dimensionally stable, rot-resistant
  • brine resistant
  • No water absorption
  • Use in digital technology (e.g. DVD)
  • Comprehensive recycling system
  • Very high light transmission with transparent colors (solar effect)
  • Impact-resistant (hail resistance up to 30 mm grain)
  • Smooth surface (easy to clean)
  • Usually available in all RAL colors
  • Algae do not adhere
  • UV-resistant
  • Special cleaner required for cleaning

Foamed profile

  • Foamed profile
  • PUR connections
  • Chambers filled with PVC foam
  • Practically no water absorption
  • No end caps
  • Radius work is possible on site
  • hail-proof in its function
  • More windproof due to higher weight
  • Storm-proof only with wind protection
  • Good insulation value
  • Smaller selection of colors (mostly white, light blue, grey)
  • High buoyancy force, loadable up to 100 kg/m²

Solar profiles

  • The classic solar profile has a transparent upper side and a black underside, allowing the water temperature to be increased by up to 3 °C per day.
  • The black underside of the profiles prevents the penetration of UV light into the pool and thus the formation of algae.
  • With favorable solar radiation, a water temperature of 26 °-28 °C is possible without additional heating.
  • Semi-transparent profiles also enable a heating effect.
  • The brighter the underside and the more diffuse the upper side, the lower the thermal effect.
  • Condensation forms due to temperature contrasts and cannot be avoided, but does not reduce the thermal effect. However, it is practically invisible on profiles with a diffuse top surface, e.g. in white aluminum black.

Cleaning and care

  • The curved surface of the profiles allows the pool water to drain away quickly, preventing excessive evaporation.
  • The absolutely smooth surface, especially with polycarbonate, makes the profiles easy to clean.
  • Polycarbonate has a hard and smooth surface, to which the lime crystals cannot adhere so easily and the soot particles contained in the air do not diffuse into the surface.
  • Algae cannot adhere to the underside of the polycarbonate profiles.
  • Cleaning should always be carried out on an as-needed basis.
  • Polycarbonate and PVC covers should be cleaned of coarse dirt and leaves before winter storage, as should the roller blind shafts.
  • In the case of PVC, discoloration may occur due to the tannic acid contained in the foliage.
  • Before using the roller shutter, reduce the hardness of the water to avoid excessive limescale deposits.
  • Always ensure that the water quality is perfect.
  • Roll up the roller blind regularly.
