Energy & Solar
Our solar panels have a transparent or semi-transparent surface and a black underside. Sunlight penetrates the panels, and the dark underside converts it into heat and transfers it to the pool water—your pool is heated using pure solar power, without any electricity.
That depends on the location, pool size, orientation, and usage—it would be unreliable to give general figures. The greatest source of energy loss in a pool is evaporation; a cover acts like a lid on a pot and significantly reduces this loss. For your specific situation, we’d be happy to provide you with a customized energy savings estimate as a guide.
The Design Cover series in PC and PVC is available in a solar version (Design Cover PC: 6 of the 11 standard colors in the solar version, including Carbon Metallic). The Mini Cover is not available in a solar version.
Yes. Less evaporation means less water needs to be added and less evaporation of water treatment chemicals. The reduced exposure to UV light also helps reduce algae growth.
Yes. With the heat pump, the need for supplemental heating decreases, and dehumidifiers in the indoor pool don't have to run as much.
Safety & Standards
Since 2006, we have had selected products tested by LNE (TÜV France) in accordance with the French safety standard NF P 90-308. The certificate is available for download on our certification page.
The Design Cover series features a fourth hollow chamber that provides increased buoyancy, which enhances safety. However, enhanced accident protection is only ensured if there is a handrail or edge running the entire circumference of the pool; additional securing with straps and a retrofittable carabiner safety device further enhance this protection. For overflow channels, accident protection is only possible when the water level is lowered and a handrail runs around the entire perimeter. Important: A cover never replaces the duty to supervise.
The profiles in the Design Cover series (PC and PVC) are designed to support up to 100 kg in total, while the Mini Cover is designed to support up to 80 kg. This enhances safety, but does not mean you should step on the cover.
Yes—some of our products, such as the DIN EN 17645, meet Environmental Performance Class A, the highest efficiency class for pool covers.
Design & Individuality
Design Cover PC: 10 standard colors plus any RAL color (including the Solar version), including the new Carbon Metallic finish. PVC: 3 colors (Solar/White/Gray), Mini: 2 colors. This means we have more certified colors than any other manufacturer.
With the in-ground system, the reel system disappears out of sight into a shaft—when open, only the pool is visible. The above-ground system is visible at the edge of the pool and is easier to retrofit.
Design Cover PC (polycarbonate): dimensionally stable up to approx. 120 °C, very smooth surface, available in all RAL colors, 5-year warranty — our recommendation, especially for high thermal loads. Design Cover (PVC): up to approx. 60 °C, 3 colors, 3-year warranty. Mini Cover (PVC 9/50) for small pools, 2-year warranty.
Technology & Propulsion
Via a wireless handheld transmitter or a key/programming switch. We develop and manufacture motors and control systems in-house in Germany (PS1 switch, winner of the Golden Wave Award).
Yes—our drives are also available in a brine or saltwater version as an option. The standard drives must not be used in saltwater.
Yes. Our clip system allows individual profiles to be replaced at any time—which saves time and money during repairs or adjustments.
You can find first-aid solutions for common problems (handheld transmitters, limit switches, switches) in our troubleshooting guide, which includes step-by-step instructions and videos; your specialist dealer or our service team can also assist you.
Winter & Weather
The design cover profiles are particularly durable thanks to their increased wall thickness (approx. 1.45 mm, about 81% more material than is standard on the market) and have been tested according to hail class HK 2–3 (hailstones up to 3.0 cm, VKG product hail register, Switzerland). The scheduled re-audit is currently underway.
Why such a test is not a matter of course: The amount of hail a profile can withstand depends on the material composition and the profile geometry. Even colour pigments alter the material’s properties, whilst the shape and wall thickness determine how the impact energy is distributed. The test therefore does not simply assess ‘the material’ in general, but the finished profile.
Yes, the profiles are designed for year-round use. Please consult your specialist dealer for details on winter storage.
Installation & Dimensions
In many cases, yes—especially for above-ground pools. Whether this is possible and how it works depends on your pool; we’ll clarify this in the quote or during the site survey.
No—unlike many other types of covers, our above-ground system does not require tracks. The edge of your pool remains clear, and there is no need to drill into natural stone or patio pavers.
Delivery and installation are handled exclusively by authorized specialist dealers/pool builders—this ensures quality and warranty coverage. Upon request, we also perform installations on behalf of our specialist dealers and provide service to their end customers—using our own measurements, our own design, and our own installation team.
We manufacture custom-made products, including special shapes. There is virtually no upper limit—the largest system we have built to date measures 22 × 50 m. We determine the exact dimensions during the on-site measurement.
Costs & Offer
For standard systems (approx. 4 × 8 m), the delivery time is usually around 4–6 weeks. Custom colours and sizes take a little longer. We will provide you with a firm delivery date for your system in our quotation.
Every system is custom-made—the price depends on the pool size, model (PC/PVC/Mini), color/solar, in-ground/above-ground, and motorization. As a general guide: Our systems start at approximately €10,000. We deliberately do not quote a flat rate, but instead calculate the exact cost for your pool—you’ll receive a no-obligation quote in just a few minutes via our inquiry form or by phone.
Because a flat online price wouldn't do justice to your unique pool. We calculate the cost of each system individually—so the final price is exactly right, with no hidden surprises.

Warranty & Service
Depending on the material, effective from the date of delivery: Design Cover PC—5 years, Design Cover PVC—3 years, Mini Cover—2 years (in accordance with the warranty terms and conditions/Terms and Conditions).
Exclusions include, among other things, improper installation (by a non-certified specialist), failure to follow the instructions, force majeure (e.g., lightning, power surges, hail exceeding the certified class), and normal wear and tear. Unauthorized modifications to the drive or control system will void the warranty.
Your specialist dealer remains your point of contact. In addition, our troubleshooting guide with step-by-step videos and our AI assistant, Rosi, on our website are available around the clock to help you—and as a manufacturer since 1983, we continue to supply replacement parts even years later.
Yes—as a manufacturer with our own production facility in Bad Tölz for over 40 years, we ensure a long-term supply of replacement parts; individual profiles can be replaced using a clip system.
Comparison
We, too, offer a slat/roll-up cover—but with some differences: a 4-chamber profile with a curved shape (more buoyancy, better water drainage, self-cleaning), increased wall thickness (~1.45 mm), solar heating effect, hail resistance class HK 2–3, PC available in all RAL colors, and individual profile replacement via clips.
A tarpaulin is simply laid loosely over the surface and offers neither walkable buoyancy, a fixed hail resistance rating, nor the appearance and durability of rigid profiles. Our profile cover is sturdy, durable (up to a 5-year warranty), and visually appealing.
A pool cover is a large structural element; our cover lies flat on the pool, is invisible (in-ground) or discreet (above-ground), and is much less conspicuous in the garden.
Made in Germany for over 40 years, in-house motors/control systems/manufacturing, solar heating effect, DIN EN 17645 Class A, HK 2–3, all RAL colors, 3,000+ customers worldwide, and multiple awards (Plus X Award, Golden Wave, Marke des Jahrhunderts).
Over 3,000 customers worldwide—ranging from private backyard pools to premium hotels to projects with architects and municipal swimming pools. You can find a selection on our References page.
