Underwater Windows: Rectangular Glazing
Hydrosight specializes in precision-engineered underwater windows, serving as a durable, reliable, and load-bearing solution for any setting. We are the leading experts in this field, ensuring both safety and a crystal-clear, uninterrupted view beneath the water's surface.
Product Focus: Rectangular Windows
Our rectangular windows are framed on all four sides and designed for seamless architectural integration. They are primarily used to separate dry environments—such as the interior of a building or dry observation area—from the body of water outside.
Every Hydrosight window is built with the safety of the client's setting as the highest priority, a commitment proven by our experience and superior design standards.
Applications for Underwater Windows
Our team has installed transparent acrylic and glass glazing in diverse settings around the world as part of hundreds of custom projects. You've probably experienced these large transparent panels—what Hydrosight refers to as 'underwater windows'—in public spaces, such as in large public aquariums. Apart from aquariums, these robust, load-bearing windows have many other uses and are valuable in a variety of market sectors. Let's explore some other types of applications where our expertise shines:
1. Residential Buildings
Modern architects have recently discovered underwater windows as a new design feature. When used in pool walls, they can illuminate adjacent rooms and give the swimming pool a unique design feature. For swimmers, it feels as though they are in their own fish tank—in a positive way! A window opens up the pool to its surroundings, integrating the water with the space and creating a sense of boundless serenity.
2. Underwater Windows in Hotels
Public pools and hotels are striving to differentiate themselves from their competitors and provide an enhanced experience for their visitors. Take a look at the ratings on ratings at Booking.com for the Helsinki pool that Hydrosight helped to build. It's a great example of how Hydrosight can provide you with the gear for unforgettable experiences.

3. Film / Photography
Film directors and cameramen have discovered the use of underwater windows when shooting underwater scenes. This spares them the burden of scuba diving and the expense of the specialised equipment required. Any photographer who has shot underwater scenes will tell you of the difficulties involved.
Professionals have the time and ability to capture the right light and timing when shooting behind a window.
The quality of underwater shots taken through Hydrosight windows is superior to that achievable with underwater cameras. Read an extended explanation here.
4. Sports Facilities and Public Pools
Underwater windows were originally used to aid swimming and diving instruction, enabling coaches to observe swimmers and divers in action. Coaches can stand at eye level with swimmers while staying dry and can even use cameras to televise all aquatic activities.
Diver tank viewing ports are possible even at great depths. In 2019, Hydrosight technology increased the maximum depth from 11 metres (35 feet) to 20 metres (60 feet).
5. Other Applications
Other use cases include scientific observation, architectural design, industrial settings, flood protection, ship building and aquaria, among many others:
