How to choose the right window style for your home

​Your choice of windows has a big impact on the look and feel of your home. So, just how do you pick the right style for your needs? Find out in our guide.



Casement windows are popular for a reason. Not only are they attractive, easy to operate and available in a range of colours and finishes, but modern varieties are also very energy efficient and are made of high-quality uPVC.

Their enhanced ventilation and wide viewing area make them a sound choice for thousands of homes up and down the country. They're customisable, come in all shapes and sizes and – best of all – require minimal upkeep.

Tilt-and-turn windows 

A modern engineering marvel, tilt-and-turn windows look great and are seriously practical.

Their intelligent design allows you to tilt the window inwards to let air flow through your living space. Alternatively, you can create an "indoor-outdoor" feel by opening the window all the way.

They're available in a range of unique glass and colour options and are an absolute dream to keep clean and maintain. What's not to love?

Sash windows

A timeless classic with a modern twist, contemporary sash windows offer the best of two worlds. Our uPVC range combines a period look with the modern functionality needed for a safe and secure home. 

These elegant windows are fitted with a smooth opening mechanism and are purpose-built to keep out draughts. Unlike their Victorian counterparts, however, they're easy to keep clean.

If that's not enough to tempt you, they're available in a range of colour and glass options to ensure we suit your taste to a T.

Bay windows 

Picture this: it's Christmas time. Your decorations are up and the tree has taken pride of place in front of the bay window.

From the outside, it's a winter wonderland. From the inside, the sight is no different. Bay windows can add a classic, stand-out centrepiece to any home. With their unique way of highlighting the smallest of details, they're certain to make a statement.

If your home's architecture suits the style of a bay window, you'd be making a mistake to not consider this option.

With huge glass panels offering great energy efficiency and bags of natural light sweeping through your living space, it's a no-brainer.

uPVC vs aluminium 

As if choosing your new windows wasn't hard enough, you now need to choose your preferred materials.

uPVC and aluminium share many of the same advantages. They're both extremely safe, energy efficient and require minimal maintenance.

One difference that you'll probably notice right away is the price. Aluminium windows are a little more expensive than uPVC. However, they're also longer-lasting and have a unique, contemporary look that some people prefer.

Typically, uPVC windows are more popular due to their affordability, fantastic efficiency and easy cleaning. Both options are available in a range of colours and designs and are made to measure for your home.

Double glazing and triple glazing

We've all heard of double-glazed windows, right? Well, what about triple glazing?

Double-glazed windows have worked their magic for years – and if you've ever gone from single-glazed to double-glazed, you'll know what a big difference they can make.

Double glazing can help with noise reduction, energy efficiency, security and the value of your home, to name just a few of its benefits.

All of the above is increased when you introduce extra panes of glass. So, as you might expect, triple glazing is like double glazing on a bodybuilder's diet.

Not only does triple glazing offer all of the same benefits of double glazing – and then some – but it can also reduce energy bills by 40% thanks to its exceptional energy efficiency. 

Better yet, our triple-glazed windows are made with extra-thick, 40-millimetre units to trap heat more effectively and really make a dent in those ever-rising energy bills.

Are you debating whether triple glazing is worth the extra cost? In this instance, we would say "absolutely." With a 40% reduction in energy bills, we're sure the windows will pay for themselves in no short order.
