Advantages of Hydrosight Underwater Windows
Wide Range
From the smallest porthole to a glass wall spanning the entire length of the pool: we have the right size for you.
Our standard windows are available in sizes up to 11 m x 3 m. We can also supply larger panels on request. These are then bonded and tempered at the factory.
Build for a lifetime.
Five-year unlimited warranty and virtually unlimited life expectancy.
Compatible with all Pool Types
Hydrosight windows are engineered for seamless integration into any pool construction—tiled, linered, stainless steel, exposed concrete, and more—ensuring a secure, watertight fit every time.
Simplified Integration
Hydrosight windows are designed for straightforward integration into your pool structure, requiring no special prior skills. Whether you are a dedicated pool builder or a general contractor, placing a Hydrosight window is a clear process. Even when facing non-ideal construction conditions, the window will fit securely and ensure immediate watertight security.
Turnkey Solutions
As an alternative to installation by a local specialist or by yourself, you can also commission Hydrosight to install your glass walled pool windows. Benefit from our many years of experience. Our team is available worldwide by prior arrangement.
Total Installed Cost Advantage
All Hydrosight underwater windows feature a stainless steel frame engineered for maximum installation efficiency. This simplified and reliable integration process significantly reduces the Total Installed Cost (TIC) of the overall pool project, simultaneously increasing the predictability and certainty of the construction planning process.
Waterproof on Delivery
When choosing your product, remember to make sure that the windows you select are reliably sealed. Hydrosight is the only supplier to offer you windows that are guaranteed to be waterproof and tested ex works. The two tested seals give you double safety.
Robust
Acrylic glass has many advantages over laminated safety glass. Acrylic is extremely resistant to breakage and cannot splinter.
For Indoors and Outdoors
Taking into account the maximum and minimum temperatures, Hydrosight calculates the necessary expansion joints in our steel frames. Naturally, the product is suitable for outdoor applications. All windows are absolutely UV-stable.
No Condensation
Acrylic glass is a natural insulator. As a result there are no thermal bridges and condensation cannot occur. By the way, acrylic is also more transparent than laminated safety glass.
Made in Germany
For over two decades, Hydrosight has set the standard in underwater glazing—engineered and manufactured in Emmerich am Rhein with precision, service, and quality at its core.

Hydrosight delivers precision-engineered underwater windows to projects worldwide. Trusted by professionals across Europe, the Middle East, North America and elsewhere, our in-house installation team and global partner network ensure reliable service wherever you build.
