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 are engineered and manufactured in Germany, delivering 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.
