Traditional Designs, Modern Performance

Our sliding sash windows are inspired by heritage designs and given a modern twist. They are manufactured using high-quality uPVC profiles and advanced double glazing so that you can benefit from traditional aesthetics and modern performance.

They are perfect for modern new builds as well as period properties, adding a touch of heritage charm to any home in Cowplain. Plus, when you choose us, you will also be able to entirely customise the design. We offer wood effect foils, so you can get the look of timber, and modern alternatives, such as anthracite grey.

Live in a conservation area? Need not worry. These windows allow you to maintain the character of your home whilst benefiting from improved thermal performance, security, and durability. In fact, our sash windows are even suitable for Sever rated climate areas, and tight weather seals prevent damage from leaking, mould, and dampness in your home.

Bespoke Sash Window Designs

We know that every home is different, which is why we have such a large range of design options for you to choose from. At Aperture Windows & Doors, we give you the complete creative freedom to design your dream windows.

You will be able to choose from over 150 stunning RAL colours from the REHAU Acryl II colouring system, which will be imbued in the frame so that they will not flake or fade as painted windows can. There are neutral and bright options, so you can be as bold as you like.

We also offer 19 unique textured wood foils, including Classic White, Mahogany, Rosewood, and Golden Oak. The benefit of our foils is that they allow you to get the look of timber with the durability and longevity of uPVC.

Often the smallest details are the most important, so we have multiple window accessories available in a range of vintage-inspired and modern styles so that you can put the perfect finishing touch on your design.

Sliding Sash Window Benefits

Sash windows offer too many benefits to mention, but here are just a few!

Thermally Efficient

Our sash windows feature triple chambered profiles for exceptional thermal performance. Combined with double or triple glazing, they achieve ‘A’ Windows Energy Rating as standard, keeping your home warmer for longer.

Modern Security

Despite their traditional style, our sash windows do not compromise security. They feature state-of-the-art locks and anti-jemmy security bars so that you can have complete peace of mind that you and your family are safe.

Customisable Designs

You will have the creative freedom to customise almost every element of the design. We offer a stunning selection of colour finishes and wood effect foils as well as various window accessories in a range of styles to complement your Cowplain property.


Unlike traditional timber sash windows, uPVC will not absorb moisture, so you will not have to worry about rotting, bowing, or cracking. In fact, uPVC sash windows can last for over three decades without needing repairing or replacing.
