Sustainability is taking a front seat in every walk of modern life.
Whether you’re noticing a rise in the number of electric cars on the road, recyclable packaging, or the increased investment in public transport, more and more people are doing their bit to help preserve our planet and reduce their environmental impact.
If you’re wondering how your home can become as sustainable as possible, your windows are a good starting point.
We’ll explain why in this blog.
Aluminium windows have thermal break technology to reduce heat transfer.
Why should homeowners start looking for sustainable solutions?
Old, inefficient window frames can be a major source of heat loss, which means higher energy consumption through increased use of radiators for example, pricier utility bills, and a bigger environmental footprint.
The good news is that modern sustainable windows can help tackle all of that in one go.
What are the most eco-friendly glazing options?
Recycled uPVC windows: modern, energy-saving, and low-maintenance
At Warwick Development, our uPVC windows are made using multi-chambered profiles for superior insulation and a more comfortable indoor climate. Not only do they help to achieve lower energy bills, but they’re also manufactured from recyclable materials, meaning they use fewer natural resources in production.
We offer a full range of styles, including:
They’re A-rated for energy efficiency, offer high security, and can be finished in one of 30 colours – including realistic woodgrain effects for a traditional look with less maintenance.
uPVC can be finished to replicate the appearance of timber.
Thermally broken aluminium: lightweight and long-lasting
Aluminium sometimes gets a bad rep in the eco world, but thanks to thermal breaks (a layer of material designed to stop heat passing through) and improved manufacturing processes, today’s aluminium frames are among the most eco materials available.
Our aluminium windows are built for performance, regardless of whether you choose our flush sash, casement, heritage, or steel-look options. They:
- Feature advanced thermal insulation
- Have an A+ rating in the BRE Green Guide
- Are fully recyclable
- Offer a sleek finish with minimal frames and more natural light
They’re a great option for those who want a modern look with minimal carbon emissions over the product lifecycle.

What options should you consider for a sustainable upgrade?
Choosing the right window style isn’t just about how it looks – it also affects how well your home performs. Here are a few sustainable window options we often recommend:
Triple glazing for maximum insulation
Where double glazing used to be the go-to, triple glazing is now seen as a significant step towards reducing energy loss and improving your home’s energy efficiency.
Triple glazed units reduce solar heat gain in summer, cut down on air leaks, and keep homes warmer for longer – all while keeping carbon emissions in check.
Vertical sliders with modern features
Love the charm of sash windows but want something more efficient?
Our uPVC and aluminium vertical sliders offer the traditional look with all the energy savings of modern design.
Sliding windows are a great choice with increased ventilation too, with the vertical sashes creating wide openings that invite fresh air into your living space.
Features like tilt-in cleaning, weather bars, and ventilation options make them both functional and easy to maintain.
Sliding windows are brilliant for increasing ventilation
Casement windows
Casement windows are the UK’s most popular window style, available in uPVC and aluminium from Warwick Development.
This window is renowned for its simplicity, opening outwards from either the top, bottom, or side.
The reason for it being a sustainable choice? As well as being constructed from uPVC and aluminium, our casement windows are available in either 28mm double or 36mm triple glazing, making them A rated for energy efficiency.
You’ll enjoy a window that’s tailored to your home, with the options of mock sash horns and Georgina bars for an authentic touch, that also saves you money on energy bills.
