Underwater Windows

Underwater windows are waterproof and load bearing. They provide a clear view below the water's surface. There are many possible applications: Scientific observation, architectural design or just for leisure. Underwater windows are suitable for private and public pools, Jacuzzis, large aquaria, industrial settings, residential and public buildings, for flood protection or as a design feature.

Film / Photography

Film directors and cameramen have discovered the use of underwater windows for the shooting of underwater scenes. This offers them an escape from the burden of scuba-diving and the costs of the specialized equipment required. Any photographer who has actively shot scenes underwater will tell you of the difficulties involved.

Sports Facilities and Public Pools

Originally used as an aid to swimming and diving instruction, underwater windows enable the coaches to observe swimmers and divers in action. Coaches can stand on eye level with swimmers, remain dry, and even use cameras for televising all aquatic activities.
Diver tank viewing ports are possible even at great depth. Hydrosight technology has increased maximum depth from 11m (35') to 20m (60') in 2019.

Pool Bottom Windows

Transparent elements in the bottom of water bodys are mostly found in swimming pools. Glass elements in pools are popular as a natural source of light for the rooms below. The mechanical load on horizontal windows is higher than for (vertical) windows installed in the walls. The load grows with the water level of the pool. That makes these skylights a natural supplement to reflecting pools, which tend to be less deep.

Residential Buildings

Recently underwater windows have been discovered by modern architects as a new design feature. Used in pool walls they can illuminate adjacent rooms and give the swimming pool an individual touch of design.

For the swimmers it feels like being in their own fish tank - in a positive way: A window opens up the pool to its surrounding, making the dip feel much less claustrophobic.
