Why Choose Bow Windows?

Unlike the bay window, a bow window is commonly placed on a sill and is rounder in shape, providing softer angles. This makes it a beautiful option for homeowners looking to capture more of that traditional feel.

Bow windows can be custom sized to match your property and come in a wide range of colours and finishes, allowing you to achieve the perfect look. It’s never been easier to bring the best of bow windows to your home.

Bow Windows Work to Make Your Home Bigger

A uPVC bow window is designed to create a sense of space by projecting beyond the exterior wall of a property. This provides a wider view of the outside, combining four or more casement windows which join together to form a curved arch. This means that they can offer you a bright and spacious feel wherever they are installed.

An elegantly, arched bow window can transform your home by making it appear bigger and brighter. A quick and easy room addition, a uPVC bow window can be used to replace existing bow or bay windows and can be installed in most large window openings. They are a fantastic option for bringing the best of panoramic views to your home.

Bow Window Design

A bow window is constructed using standard fully reinforced window frames. All frames are connected using structural bay poles or reinforced corner posts. The external sill is then welded together to create a continuous sill under all the frames, this means that you can bring a seamless standard of quality to your home.

It is possible to create a bow window from an existing flat window which can be done cost-effectively and without the need for Building Regulations. A flat to bow window is built with the same frame construction as a normal bay or bow window but has a new roof. This makes it easier for you to enjoy the best of what bow windows can offer you without a complete overhaul.

It won’t matter if your home is modern or traditional, you’ll be able to find something to suit.

Bay Windows Vs Bow Windows

It can be difficult to differentiate between the two uPVC windows but there are in fact, a few subtle differences between a bay and bow window design. It is these differences that enable them to offer their modern or traditional feel. If you’re after something more traditional, you’ll want to get the bow window design. Have a read below to see what the differences are:

A bay window is built using three angled panes of glass whereas a uPVC bow window has more than three panes. The higher amount of panels allows the bow window to capture its signature arched shape, which is usually lost with the fewer pane design of bow windows. This is something to consider when you’re looking to get bow windows installed as they may need more room.

Bay windows tend to project farther from your property, usually lending space for a beautiful window seat inside you home or a spot to sit, read and relax. The beloved window seat is a big selling point of the bay window. This space can also be used for decorative purposes too, serving as a spot to bring a personal touch that is going to reflect the character of your home.

Bow windows sit upon a cill that curves gently all the way around whereas bay windows usually form part of the brickwork of a property. This means that bow windows serve as bit more of a subtle addition to your home, whereas bay windows are more of a statement that is going to protrude out of your home. This is why it’s important to determine what design you want.

Thermally Efficient Bow Windows

The benefits of bow windows span beyond their aesthetic and charming appeal, they can also work to make your home a warmer and more comfortable place to be across the course of the year. This is because they comprise a build that combines a range of features that will help to increase the standard of heat retention they achieve. This includes a thermally broken profile, high-performance weather seals, and professional installation.

A thermally broken profile essentially means that there are multiple chambers in the frame that work to break up mini convection currents and trap in pockets of warm air. This means that the warmth from your central heating will stay in your property for a longer period of time, keeping you comfortable during those colder winter months. This is then enhanced further by high-quality weather seals that prevent any draughts or water ingress compromising your home comfort.

Not only does this mean that bow windows will work to keep those bitter winter winds at bay, it also means that they could save you money in the long run too! This is because having the warmth from your central heating stay in your property for a longer period of time means that you could rely on it less throughout the year. In turn, this means that that you could end up with a lower annual heating bill as a result. This means that bow windows will continue to bring value long after installation.

Low Maintenance Bow Windows

It’s understandable that you want to bring a new addition to your home that isn’t going to add to the stress of life, which is why it’s so great that bow windows won’t be a culprit for this. With the inherent qualities of modern materials at their disposal, the bow windows of today don’t have any of the maintenance problems that are usually associated with older designs. This means that you won’t have to worry about any rotting, warping, cracking, discolouring, or bowing out of shape.

This is important, as bringing a window to your home that is going to fail you once it gets wet or is exposed to the elements for a long period of time is just going to cause you problems. Whether you opt for uPVC, aluminium, or timber, you won’t have to undertake a heap of maintenance jobs to keep them looking and performing their best. In fact, all you will have to do is give them a quick wipe down with a damp cloth to maintain that ‘as new’ look. Why settle for less?

Low maintenance bow windows bring more than just convenience, they will ensure that these windows work as a worthwhile investment for your property. This is because a window that is rotting or warping is going to have a range of functional or structural problems, which means that they could be used as a weak spot to gain entry into your home. If you get a window that is set to last, then the benefits they have been designed to offer will just keep on giving after installation.

High-Security Bow Windows

Feeling safe in your house has always been one of the key factors to ensuring it feels like home, which is why bow windows have been manufactured to achieve an impressive degree of security from the ground up. This means that they won’t just increase the aesthetic of your home, they’ll also ensure that it feels like a safer and more comfortable place for you to be. This is made possible by combining a range of features, including internal structures, high-security locks, and installation.

Due to the modern design of these windows, the window frame comprises internal structures that help them to capture an impressive degree of structural integrity. This means that they are able to achieve a modern standard of security from the ground up, ensuring they can withstand common impact techniques that would-be intruders use to get into your home. No matter the material you opt for you, you’ll be able to enjoy this standard of quality.

This security is then enhanced further through high-performance locking systems that are fitted into the frame. These locks are designed to engage at multiple points of the frame to ensure there aren’t any potential weak spots that could be used as a point of leverage to get into your home. The reason it is so important to get a professional installer is that they’ll be able to integrate the locks into the frame to prevent them from being easily accessed. This combats a modern burglary technique!

Another factor to consider when it comes to your bow window security is if it has Secured by Design certification. Secured by Design (SBD) is a police backed initiative that has been put in place with the intention to ‘design out crime’ when it comes to home improvement solutions. If your bow window has SBD certification, then you’ll know its undergone a stringent and meticulous testing process to guarantee it can hold steadfast against the latest burglary techniques.
