Bespoke Porthole Windows
We specialise in processing toughened safety glass, which we use to create our secure windows for your boat. We trust in our products, so we offer a 1 year warranty as standard.
Our safety glass is up to five times stronger than standard glass for reliable protection and is also compliant with E11 43R regulations for your peace of mind. We use the same glass for our horsebox, plant machinery, and vehicle windows.
With our toughened safety glass windows, you can choose:
- Large window sizes
- Glass tints
- Opening styles
- Bonded or framed variations
- Single-glazed, double-glazed, or double-glazed with thermal break

Framed Porthole Windows
If you’d like to maintain the traditional look of your boat, our framed porthole windows are ideal. We can design and supply two different types:
- Concealed porthole windows: This type of window is screw-fitted, but we can hide all of the external fixings using a concealed filler strip for a smooth, modern look. While this style is only available as single-glazed, we have plenty of customisation options available, including frame finish, glass tint, and an opening style.
- Clip in porthole windows: Installed from the inside of your boat, our clip-in porthole windows have no fixing holes and are attached using metal clips that screw against the inside body of your boat. Choose from a double or single-glazed porthole window to keep your space warm and comfortable or with a thermal break style to reduce condensation.
Bonded Porthole Windows
Bonded porthole windows are a sleek and modern choice for your boat. With our innovative design, you can benefit from a truly original look.
Our dark grey privacy glass is also extremely popular, as it can separate your space from the outside world and act as a deterrent against theft.
Also available in single glazed, double glazed, and thermal break variations. With our double glazed bonded porthole windows you will benefit from noise reduction, and our thermal break windows allow you to benefit from a thermal barrier to help reduce condensation.
Whatever style of porthole window you’re looking for, contact us today to discuss your options.
Can you get round windows that open?
Yes, our glass specialists at Caldwells Windows can design round porthole windows with a variety of opening mechanisms in mind. With a round porthole window, you can benefit from an aesthetic look as well as a practical addition to your space.
