Unlike most motorized shelters or pool shutters that require power work, the Coverseal 4-Season Pool Cover operates autonomously.
In the Automatic version, the energy necessary for operation of the Coverseal is produced by solar panels that directly charge the integrated batteries. In the Semi-Automatic version, it’s possible to recharge the batteries present in the control box independently by an outlet in your home.
Coverseal can also install an indoor pool cover, either by means of the Semi-Automatic model without providing a power supply, or with the Automatic model by providing an incoming feed.
Regardless of the model chosen, you preserve the quality of your water, optimally secure your pool and achieve significant energy savings.
Category: General
Like any material exposed to UV, the membrane may undergo slight discolouration over time. This phenomenon, although natural, will be more pronounced on dark membranes.
The trim of the cover, meanwhile, is powder-coated. The paint is, therefore, very resistant over the long term and suited to the environment of the pool. However, just like a car body, there can be slight discolouration with sun exposure.
It is also possible to find trims with more specific finishes, namely a “mirror effect” or “metal effect”. In this case, the trim is made using composite panels. It is also a product that will go through the years without losing its quality.

Unlike other protection products, the Coverseal pool cover does not require any special intervention as winter approaches. Once installed, it remains fully functional without the addition of specific equipment for wintering. The only precaution: maintain the usual water level, so that it supports the membrane in case of heavy snowfall. This principle preserves the cover from any excessive stress.
A true 4-season product, Coverseal retains its elegance throughout the year and effectively protects your pool. In the spring, you enjoy preserved water: no clumps of leaves and limited photosynthesis!
Category: General
Coverseal effectively limits photosynthesis, thus preserving the purity and balance of the water. By reducing the pool’s exposure to sunlight and impurities, it maintains more stable water indices, for water that is more pleasant to the touch and visually flawless.
This optimal protection also allows you to reduce the use of treatment products, which are often expensive, not very ecological and irritating to the skin, while prolonging the pleasure of healthy and comfortable swimming.

To the eye, the membrane presents impeccable tension, with only a slight technical bend of about 1 cm per meter of width. This tension, combined with centrally located drain holes, prevents any water stagnation, thus limiting the accumulation of dirt. Leaves deposited on the membrane are easily swept away by the wind.
Over time, the membrane retains its perfect hold, the initial bend does not increase. In areas with extreme weather conditions, it is even more important to maintain a normal water level so that the water supports the membrane during heavy snowfall and preserves its aesthetics.
Category: General
Yes, your pool stays clean once protected with a Coverseal cover. Unlike submerged or above-ground shutters, our cover does not plunge into the water: its stretched membrane acts as a barrier against external dirt.
Leaves, dust or other impurities do not stagnate on the surface, they are naturally swept away by the wind, avoiding the formation of dirty puddles as is often the case with a conventional tarpaulin. Result: cleaner water, longer, with less maintenance.
Category: General
No. Each Coverseal cover is completely custom-designed, according to the specifics of your pool, your environment, and your aesthetic preferences. No predefined format: each configuration is customized in every detail, to guarantee perfect integration and optimal protection without compromise.

There are 2 types of rails, namely standard rails and all-surface rails. In most cases, the standard rails are installed. Their 36 mm wide by 10 mm high profile has been specially designed to remain discreet and integrate harmoniously with the pool environment. However, there is another type of rail, namely the all-terrain rail, that can be adapted to supports that lack density or flatness. In addition, the rails are never empty: the belt is always integrated, guaranteeing maximum safety and avoiding any risk of unpleasant contact.

The expected life of the batteries on the Automatic and Semi-Automatic models is about 4 to 6 years under normal conditions of use. However, during exceptional weather conditions (very high or very low temperatures), the service life of these batteries may be degraded. For Automatic models equipped with a winterization switch (previous version to 2025), it is important not to forget to set it to “off” from 1 September to 1 May. During this period, as there is insufficient sunlight, the batteries could then fall into deep discharge and they would have to be replaced.

Unfortunately, too many factors are taken into account to establish an accurate theoretical calculation of the insulation value of the Coverseal (delta T°, air mass trapped under the membrane, wind, rain, etc.). Therefore, it is not possible to quantify it, but the Coverseal ensures an almost perfect seal, blocking almost all evaporation. This significantly reduces heat loss, which leads to real energy savings and limits the need for water filling, for more sustainable and economical management of your pool.

Category: General
Cylinders are an option available on the Automatic model, the primary purpose of which is to allow the Coverseal to overcome larger obstacles effortlessly, while optimising the tightness of the cover. Cylinders help preserve water quality by limiting the intrusion of impurities and conserving heat. Beyond their technical function, they also offer an elegant finish: the cover is delicately placed on the ground in a fluid and discreet gesture that demonstrates the high-end quality of your installation.
Distinctive detail: an Automatic model equipped with cylinders can be recognized by its square box, as opposed to a rectangular shape for the version without cylinders.
Category: General
Coverseal pool covers are designed with premium materials. The wear of the membrane depends mainly on climatic conditions, the maintenance provided and the daily use.
It can therefore be estimated that a membrane replacement will be necessary after 10 to 12 years, depending on the environment and climate of the country where the Coverseal is installed (frost, snow, extreme heat, sand-laden wind, etc.). An essential point, however, is regular cleaning of the rails. Indeed, the presence of sand or abrasive particles in the rails can accelerate the wear of the mechanical parts and, ultimately, the membrane.

Coverseal pool covers have been manufactured in Belgium for more than 15 years and have globally recognized patents. They are commercialised by many Partners in different European countries (Belgium, Netherlands, Luxembourg, France, Spain, Italy, Switzerland, Germany, Austria, Norway,etc.) as well as in the Middle East and the United States.
When manufacturing your pool cover, the climatic conditions of the pool cover installation will be taken into account. High or low temperatures, frost or heavy snowfall are all factors that Coverseal has taken into account when designing its Product. Thus, your pool is protected throughout the year and regardless of its location.

A winter cover protects your pool in cold weather, but it remains a seasonal solution, designed above all for stopping use. The Coverseal, on the other hand, is a four-season system that offers optimal protection all year round.
Thanks to its membrane stretched over the water, it prevents leaves, dust and other debris from polluting the pool, limits photosynthesis and preserves water quality. It also retains the accumulated heat and enhances the safety of your swimming area.
In other words, while the winter tarpaulin plays a limited role, the Coverseal combines aesthetics, performance and durability throughout the year.
Category: General
Unlike a submerged or above-ground pool shutter, the Coverseal is a true 4-season product. It provides optimal protection all year round, offering more cleanliness, safety and insulation than any shutter on the market.
While a shutter floats directly on the water, inevitably letting leaves and debris fall back into the pool when it opens, the Coverseal, stretched over the edges, protects your pool from impurities.
Compared to a shutter with solar blades, the difference is in the insulation: while the blades can significantly increase the temperature of the water, the Coverseal traps the accumulated heat without requiring additional protection.
Finally, its design severely limits photosynthesis, thus preserving water quality and reducing the use of treatment products that are often expensive, unfriendly to the environment and irritating to the skin.
Category: General
Choosing a Coverseal means offering yourself high-end protection that combines safety, performance and elegance. Its innovative design effectively protects water from dirt and temperature variations, while reducing the consumption of water, energy and cleaning products. Easy to use and perfectly integrated into your environment, it ensures optimal comfort throughout the year, for a pool that is always clean and ready to use at any time.
Opting for a Coverseal also means choosing a Belgian company that places innovation at the heart of its know-how and favours the short circuit by collaborating with trusted local Partners.
Category: General
Unlike a swimming pool enclosure, a Coverseal offers real comfort in everyday use. Certainly, some shelters allow you to swim underneath them, but their handling is much less practical. In addition, a shelter is often voluminous and imposes its presence, while a Coverseal, thanks to its minimalist and 100% customizable design, blends harmoniously into your environment.
It also limits photosynthesis, which preserves water quality, significantly reduces the use of chemicals, and allows you to enjoy healthier water.

Practical questions

Yes, by reducing the intensity of the spray and using a neutral pH soap. Special attention should be paid to rails where regular cleaning is essential to ensure the performance and longevity of your cover. For the trim, we recommend using a microfiber cloth to preserve its appearance and durability.

The membrane that strongly limits photosynthesis and prevents leaves from falling into your pool should keep you from having to resort to shock treatments to purify your pool water. Nevertheless, under exceptional circumstances, this type of treatment may be considered. However, it is strongly recommended to keep the Coverseal open for 24 to 48 hours, to avoid any excessive concentration of chemicals that could damage the membrane.

No. Repeated shocks or excessive pressure may cause deformation of the trim or damage to the mechanics. Such damage is not covered by the warranty.

Yes, on the latest versions of the Automatic model, it is now possible to control your Coverseal from a smartphone while keeping a direct view of the cover when handling it, for safety reasons. The dedicated application also allows you to consult technical parameters such as:
– the charge level of the batteries,
– the number of opening/closing cycles performed,
– the history and details of alarms in the event of malfunction.
For previous versions, an upgrade is possible in order to activate the opening and closing control via your smartphone. We recommend that you contact your Partner directly for more information.
It is not necessary to walk on it to clean the membrane: a low-pressure cleaner (set to moderate power) or a telescopic handle is more than enough. However, you can walk on top of them barefoot or with flat-soled shoes, without any risk.
A quick reminder: the Coverseal provides effective protection in the event of an accidental fall, but it is not designed to be used as a playground.
Our covers do not require any special technical maintenance. However, it is strongly recommended to carry out regular cleaning of the rails and mechanism to remove any accumulation of sand, soil, leaves, branches or other dirt that may affect proper functioning and life of the cover.
In addition, it is necessary to respect the rules stated in the user manual, such as maintaining the appropriate water level in your pool, in order to preserve the safety of the cover.
Regardless of the model, your pool cover can always be opened or closed manually. Even in the event of a battery failure, there is always a solution! However, the manual manoeuvre should only be used in the event of a power failure and should not be used to loosen your cover.
1. Remove the 2 flaps (one on each side of the trim). For modules without cylinders, go directly to point 3.
2. Lift the trim on each side until you hear the click.
3. Identify the red motor cable and disconnect it.
4. Identify the manual manoeuvring flange and insert the extension provided during installation.
5. Place the racagnac (ratchet wrench) at the end of the extension, and adjust the knob to the desired position.
You can now operate the system to open or close the cover. To put your cover back in place, reverse the steps from 5 to 1. To lower the trim (only on models equipped with cylinders), actuate the two levers inside it by lifting it slightly before lowering it again.
Yes, it is important and even mandatory according to AFNOR standard NF P90-308.
This makes it possible to guarantee the safety of your loved ones and the good condition of the cover by directly detecting if someone is in the pool or if any obstacles are on the membrane (branches, wipes, ball, etc.).
Yes The material used to manufacture the membrane has been used for many years in construction, in particular to make large structures such as exhibition palaces. It is supplied by Serge Ferrari, a world leader in this field, and meets the most demanding standards, including NF P90-308 (December 2013).
It is a pre-stressed membrane coated with several layers of polymer, capable of supporting several tons and recovering its initial shape after deformation. It is, therefore, a solution that guarantees safety and tranquillity for the whole family.
On previous generations of Automatic models, the winterization switch allowed you to disable the remote control receiver to preserve the batteries during the low season, when the sunshine is lower. It is recommended to place it in the OFF position from 1 September to 1 May. Otherwise, the batteries could fall into deep discharge and require replacement.
Note: on the latest versions of this model, this switch is no longer present, because energy management has been optimized.
All you need to do is:
– close the cover completely
– maintain the water level of your pool according to the instructions in the user manual;
– clear the solar panel(s) of the Automatic model in case of heavy snowfall to maintain a good charge of the batteries
– set the winterization switch to off in order to preserve the batteries (previous versions of the Automatic model)
Thanks to the membrane, photosynthesis is strongly limited: no noticeable dirt is found in the spring. For optimal results, it is advisable to run the filtration only a few hours a day during wintering.
