Whether you’re after a contemporary look or something more traditional, there’s a uPVC window style to match your vision. You’ll find them in a range of colours, from crisp white uPVC windows to realistic woodgrain finishes, and they’ll perform hard to keep the warm air in and your heating costs down.

At Warwick Development, we’ve been helping homeowners make smart window choices for over 30 years. Whether you’re looking at new windows for a renovation or a fresh build, we’re here to break down the jargon and help you find exactly what you need.

How to choose uPVC windows for your home: Selecting a style

The style of window you pick isn’t just about looks (though that matters too). It’s about how the window actually operates day-to-day. Different styles suit different rooms and preferences, so it’s worth understanding what each brings to the table.

Casement windows

Casement windows are the most popular choice for homeowners across the UK, and for good reason. They’re hinged at the side or top and open outwards like a traditional door. Think of them as the reliable workhorse of the window world.

• Available in a choice of 30 attractive colours, including realistic woodgrain finishes
• A-rated energy efficiency with U-values as low as 0.8
• High-security multi-point locking systems
• Double glazed (28mm) or triple glazing (36mm) options available
• Perfect for both period properties and modern homes

Flush sash windows

If you want that classic timber window look without the maintenance headache, flush sash windows are your answer. The frame sits flush with the wall for a sleek, contemporary feel that still nods to tradition.

• A-rated energy performance with U-values as low as 0.9
• Shoot bolt locking for added security
• 19 standard colours plus 32 additional colour upgrades
• Slimline frames for a refined appearance
• Ideal for listed properties and conservation areas

Vertical sliders

Vertical sliders (or sash windows) slide up and down rather than swinging open. They’re brilliant if you’ve got limited space outside your window or simply prefer the elegance of the sash style.

• Smooth, balanced operation
• A-rated energy ratings across the range
• Available in multiple colours and finishes
• Great for period properties looking to maintain character
• High-security locking systems built in

Sliding windows are brilliant for increasing ventilation

Tilt and turn windows

Tilt and turn windows are the versatile option. Tilt them inward at the top for gentle ventilation, or swing them fully open like a casement window. Perfect if you want flexibility.

• Two operating modes for maximum versatility
• Elite energy efficiency with uPVC
• Excellent for hard-to-reach spaces
• High-security credentials
• Contemporary, minimalist appearance

Other factors to consider

Insulation

Here’s the thing: a beautiful window won’t matter much if your home feels like a fridge. Insulation is crucial. Look for multi-chambered profiles that trap warm air and keep the cold out.

We manufacture uPVC windows with impressive thermal performance. Our casement windows achieve U-values as low as 0.8, and our Modus range goes down to 0.7 – that’s better than Passivhaus standards. More insulation means less heat loss, lower energy bills, and a genuinely more comfortable home.

Security

Your windows are entry points, so security matters. High-security locking systems aren’t just peace of mind, they’re a practical necessity.

Our uPVC casement windows feature multi-point locking systems and shoot bolt technology. Each window is BBA accredited as standard, meaning they meet rigorous security standards. Sleep soundly knowing your home is properly protected.

Finish and colour

Don’t overlook how your windows look. Our uPVC casement windows come in 30 colours, whilst our Modus range offers over 30 colour upgrades. Whether you’re after white uPVC windows, contemporary steels, or realistic oak finishes, there’s something to match your home’s style.

Energy efficiency and energy ratings

Energy efficiency directly impacts your wallet. Look for windows with A-rated energy ratings – they’re the gold standard for keeping energy bills down.

Our entire uPVC window range is A-rated. Triple glazing delivers even better performance than double glazing, with superior insulation and noise reduction to boot. If you’re serious about energy savings, triple glazing is the right choice.

Frequently asked questions

What’s the difference between double and triple glazing? Triple glazing has three panes of glass instead of two, creating an extra insulating layer. It offers better thermal performance, noise reduction, and heat loss prevention, though it comes at a higher cost. Double glazing is also a good solution for most homes.

How do I maintain uPVC windows?

uPVC is brilliantly low-maintenance. Simply wipe frames with a damp cloth and mild soapy water occasionally. No painting, no wood treatment needed.

Are uPVC windows sustainable?

Yes. Our Modus windows are made with 50% post-consumer recycled uPVC, and the material can be recycled up to ten times without quality loss.

What’s the difference between uPVC and aluminium windows?

uPVC excels at insulation and low maintenance, whilst aluminium frames offer a slimmer profile and modern aesthetic. Both are excellent choices depending on your priorities.

How long do uPVC windows last?

With proper maintenance, quality uPVC windows last 20-30 years or more. Our products come with industry-leading guarantees for extra peace of mind.
