Porthole Windows

Porthole Window

A porthole – sometimes called a ‘bull’s eye window’ – is just one example of the round window frames that we supply here at ArcOframe. With a classic circular frame, porthole windows offer a superb alternative to traditional square or rectangular windows and are guaranteed to make a statement in any room.

The porthole window is often used on boats and barges, but more and more homes are choosing to install round windows to add a unique sense of style to their property.


Why should you choose porthole windows?

Choosing something different, like one of our innovatively designed UPVC porthole window frames, will allow you to transform your space into something unique and modern.

For instance, you could use a porthole window to line the walls of your staircase to draw in lots of natural light and make your home feel more open and spacious.

They’re a brilliant feature in bathrooms, hallways and corridors, allowing sufficient light to enter whilst maintaining privacy and comfort. The curvature also works well in rooms with limited space available, making the most of confined areas.

Why not install a porthole on the ceiling? Similar to skylights, it will enable sunlight to shine through – brightening up your room during the day – and can be used for stargazing at bedtime.

If your home overlooks a beach, lake or mountain range, you could use a porthole window to your advantage. Think of it as a piece of artwork, framing the beautiful scenery that’s right on your doorstep.

Another thing worth knowing about porthole windows is that they can complement your interior décor perfectly or become a design feature of your home. It’s entirely up to you.

1. What are porthole windows?

Porthole windows are a type of round window – commonly found on ships and boats. However, increasingly more people are choosing to install porthole windows at home to create a unique boat-like ambience.

Are you looking to add a unique touch to your home from both the interior and exterior? Our porthole windows are an excellent choice. Why not join thousands of happy customers and choose ArcOframe for your porthole windows?

2. Do porthole windows open?

Yes – here at ArcOframe, we create porthole windows that can be easily opened and closed. When open, they permit light and fresh air to enter and provide a strong, water-tight and weather-tight barrier when closed.

All our porthole windows are fitted with adjustable friction and safety restrictors as standard, and optional lockable catches are available if you’d like to add an extra layer of security to your home.

3. Where are porthole windows installed?

A porthole window can transform a plain room into a unique space, creating the illusion of being on a cruise ship. Many people use them in the home as a focal point, whilst others use them as artwork to frame the view of outdoors – be it a beautiful lake or the bright lights of the city.

Bathrooms tend to be the most popular location for porthole windows as they let a lot of light in. But this isn’t to say you can’t use them in the living room, kitchen, bedrooms – or even on the ceiling to brighten up a dark or dull space! Porthole windows also look great when they’re used to line the walls of a staircase. They draw light in and create the illusion of more space.

4. What are the advantages of uPVC porthole window frames?

At ArcOframe, all of our porthole windows are fitted with uPVC (Unplasticised Polyvinyl Chloride) frames.

uPVC is a low-cost building material that offers remarkable strength and durability and – when properly maintained – can last up to 30 years.

Other benefits of our uPVC porthole window frames include:

  • Low maintenance – with no painting or sealing needed, all it takes is a quick wipe clean with soap and water to keep your porthole window frames looking like new.
  • Long-lasting – our UPVC frames are corrosion-resistant and don’t rust or rot, meaning they’ll remain strong and sturdy for years to come.
  • Excellent insulation – not only do our porthole frames prevent dampness and cold air from entering your home, but they also help to retain heat which can save you a great deal on your energy bills.

5. How do I measure for porthole windows?

When measuring up for new windows, your measurements need to be 100% accurate – otherwise, they won’t fit.

As a general rule of thumb, measure in millimetres, not inches. This will give you a more accurate result and save you the arduous job of converting your measurements from imperial to metric.

It’s also best if you measure the opening outside, taking into consideration the height from under the existing windowsill.

The opening where you plan to fit porthole windows may not be exactly square, so make sure you measure brick to brick in at least three different places – top, middle, and bottom – for the height and width. This will allow our team to get a clear idea of the size of your space.

If you’re still unsure, don’t panic. At ArcOframe, our porthole windows and frames are all made to measure and we will always double-check your initial measurements are correct.
