Advantages of Hydrosight Underwater Windows
Wide Range
From the smallest porthole to a glass wall spanning the entire pool, we have the right size for you. Standard windows are available up to 11 m × 3 m (36 ft × 10 ft); larger panels are supplied on request, factory-bonded and tempered to specification.
Compatible with all Pool Types
Hydrosight windows integrate seamlessly into any pool construction—tiled, linered, stainless steel, exposed concrete, and more—ensuring a secure, watertight fit every time.
Simplified Integration
Designed for streamlined installation with no specialist skills required, Hydrosight windows make construction quick and easy for pool builders or general contractors, even under non-ideal conditions.
Total Installed Cost Advantage
Featuring a stainless steel frame engineered for maximum installation efficiency, Hydrosight windows reduce the Total Installed Cost (TIC) of the pool project while increasing planning certainty and reliability.
Build for a lifetime.
Backed by a five-year unlimited warranty and a thirty-year no-yellowing guarantee, Hydrosight windows deliver exceptional durability and virtually unlimited operational life.
Secure Steel Frame & Sealing
Hydrosight is the only provider to deliver and guarantee fully tested watertight windows. The robust stainless steel frame incorporates a high-quality dual-seal system for critical double-layer security. It maintains integrity in chlorinated and marine (salt) water, operating from -15 °C to +45 °C (5 °F to 113 °F).
Acrylic: Clearer, Tougher and UV-stable
Our acrylic windows combine unparalleled clarity, UV stability, and natural insulation that prevents condensation and eliminates thermal bridges. Tough yet lightweight, acrylic resists breakage and never splinters, outperforming laminated safety glass in optical quality and structural integrity.
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 worldwide. Trusted by professionals across Europe, the Middle East, North America, and beyond, our in-house installation team and global partner network ensure dependable support wherever your project is located.
