uPVC Windows Swansea | Premium Energy-Efficient Windows Across South Wales

AQ Windows offer market leading windows and doors at affordable prices in Swansea and throughout South Wales. Our full range of uPVC and aluminium windows also come standard with the highest level of security installed as standard, along with an A+ rating for energy efficiency.

Swansea’s coastal climate brings damp sea air, Atlantic-driven rainfall, and brisk westerly winds throughout much of the year. Traditional timber window frames absorb moisture, warp, and require repainting every few years. uPVC windows in Swansea are engineered to withstand exactly these conditions — they will not rot, corrode, or discolour, and they need nothing more than an occasional wipe-down to look as good as the day they were fitted.

Beyond durability, modern uPVC windows deliver measurable energy savings. Every window we install at AQ Windows carries an A+ Window Energy Rating, meaning it retains significantly more heat than older single or early double-glazed units. For a typical semi-detached home in Swansea, upgrading from 15-year-old double glazing to A+ rated uPVC windows can reduce annual heat loss through windows by up to 20%, helping to lower energy bills and reduce your home’s carbon footprint.

Security is the third pillar. Every uPVC window we supply comes fitted with a multi-point locking system as standard, with PAS 24-certified and Secured by Design options available for homeowners who want the highest level of protection available on the market today.

Put simply, uPVC windows offer Swansea homeowners a combination of weather resilience, thermal performance, and security that no other material currently matches at the same price point.

All our windows are manufactured to order to meet each customer’s specifications and ensure a perfect fit for your home.

uPVC Casement Windows

The most popular kind of uPVC window in the UK is the timeless casement window, which is also one of the most popular home renovation options. A new feature that sets AQ Windows's casement windows apart from the competition is their multi-chambered uPVC profile, which requires less steel than conventional frames. With our one-of-a-kind co-extruded bubble gasket, homeowners can say goodbye to draughty windows.

The UK's most popular window style for good reason. Casement uPVC windows open outward on a side-mounted hinge, providing excellent ventilation and an unobstructed view when closed. Available in top-hung, side-hung, or fixed configurations, they suit virtually any Swansea property. Our multi-chambered uPVC profiles offer superior thermal insulation compared to standard three-chamber alternatives, and our co-extruded bubble gasket creates an airtight seal that eliminates the draughts associated with older frames.

uPVC Tilt and Turn Windows

The tilt-and-turn window system allows you to "tilt" the window or open it fully, making it a versatile solution. This way, you may improve air circulation in the home without having to remove the lock.

In addition to a fully opening side aperture—ideal for fire escapes—and a tilted pane—which can be adjusted for controlled ventilation depending on the position of the handle when opened—uPVC tilt and turn windows are ideal for larger windows because of the variety of openings they give.

Vertical Sliding Sash Windows

For Swansea's substantial stock of Victorian and Edwardian properties — particularly in areas like Sketty, Mumbles, and the Uplands — timber-look vertical sliding sash windows have historically been the expected choice.

They satisfy most local authority conservation area guidance where full timber replacement is not required.

Our uPVC sash windows are ideal for new construction or renovation projects because they combine A+ certified energy efficiency with comfort, security, and good looks.

Energy Efficiency and Window Energy Ratings Explained

All windows sold in the UK for replacement purposes are assessed under the British Fenestration Rating Council (BFRC) Window Energy Rating (WER) scheme, using a scale from G (poorest) through E, D, C, B, A, to A+ (best). The rating accounts for three factors:

Solar gain (g-value) — how much useful solar heat the glazing admits in winter
Thermal transmittance (U-value) — how quickly heat escapes through the glazing unit; lower is better
Air leakage — how well the frame seals against draughts

Every uPVC window supplied by AQ Windows achieves an A+ Window Energy Rating as standard. Our double-glazed units use warm-edge spacer bars — a significant advance over old aluminium spacers — which reduce condensation at the glass edge and eliminate the cold bridging that undermines the performance of lower-rated windows. For maximum performance, we also offer triple glazing, which can reduce heat loss through the glazing unit by a further 30% compared with standard double glazing.

Under Part L of the Building Regulations (England and Wales), replacement windows must achieve a minimum Centre Pane U-value of 1.2 W/m²K. Our standard A+ specification exceeds this comfortably, ensuring your new uPVC windows are fully Building Regulations compliant on the day of installation.
