"When building my own dreamhouse, we only choose the best contractors in their field. That is how we got to Hydrosight." John M., Architect London/Pafos

Strong and Waterproof by Design

Underwater windows need to be strong enough, but also need to be waterproof.
Hydrosight is unique in enabling you, the builder, to have these requirements covered. Hydrosight will enable you to install our underwater windows, just as any other building component. Therefore we work with glazing, that sits in a stainless steel frame. The cost of just the window is higher, but the total cost of material and installation is lower. Plus: You stay in control of your operation.

The underwater window installation procedure is easy and well tested. As a pool builder you will not require any special training to install our windows. A step-by-step manual is provided and you have email and telephone support.

Our windows do not demand top ideal conditions for operation. Tolerances in the concrete shell are acceptable and do not intervene with the functioning of the windows. Hydrosight glazing is shatter proof, so the risk of damage while on transport or installation is neglible.

"I have looked at it (the Hydrosight Website) a number of times and am impressed with it, although I have no personal experience with it ... Honestly , I looked through the website and it certainly appears viable and safe. They aren’t a Jonny come lately operation. Can I ask you guys, who are more engineering minded than me, to look at that website that Jonathan had attached, and give me your 2 cents?" a client from the USA
