Built-in security

Our windows are PAS24:2022 accredited, for enhanced protection against break-ins at no extra cost. This standard is essential to meeting building regulations for new homes and extensions.

We use Yale locking systems along with a free upgrade to shootbolt locks for maximum security. This two-stage locking mechanism allows you to fully lock the window or lock it slightly open for ventilation. Plus, the handles have key locks for added peace of mind.

Advanced glazing

Our windows feature high-performance glazing using the latest Pilkington energiKare™ technology. Each unit includes an inner pane for superior heat retention and an outer pane for enhanced light transmission. A black SuperSpacer reduces heat loss and condensation.

Available in 28mm double or 40mm triple glazing thickness, they achieve U-values from 0.70 to 1.22, exceeding energy performance standards.

What window customisation options are available?

With endless style, size, glazing and colour options, you can build a modern UPVC window to match your exact requirements.

Window colours

Choose from classic whites and popular woodgrain finishes or personalise your windows with bespoke flat colour coatings for a truly unique style. We can match most RAL colour codes or your own samples, giving you full control over your design.

*Please note bespoke colours may add up to four weeks to delivery times.

Glazing options

Tailor your windows with double or triple glazing to suit your energy performance needs. We use advanced Pilkington EnergiKare glass units as standard, with options for acoustic, laminated, privacy and decorative glazing.

You can also personalise your glass with Georgian bars, leaded designs or astragal bars for a traditional look.

Internal blinds

Our internal Venetian blinds are sealed within the window unit, offering a clean, maintenance-free solution for privacy and light control. Choose from cordless or corded systems, including single or dual magnetic sliders for smooth, cord-free operation or a corded design ideal for larger windows and maximum light entry.

Each option is easy to use and keeps the blinds protected and dust-free inside the glass.

Furniture & hardware

Finish your windows with quality hardware and handle options in a variety of styles and finishes, including Chrome, Satin, Gold, Black and White. All handles come with key locking as standard for enhanced security and moving parts such as hinges and locks are built for long-lasting, reliable performance.

Trickle vents can also be added to allow background ventilation while maintaining security and energy efficiency.

How do I measure a window?

+
Measure your window openings from the outside brickwork in millimetres. Take width and height measurements in three places, then use the smallest measurement minus 10mm to allow for fitting. If measuring from inside or on an existing window, include any cills or frame extenders but exclude stone cills. If your walls are rendered, check the brick edges by removing some render if needed. When in doubt, send us photos or consult a professional.

For a helpful guide, download and print our measuring sheet or follow our how-to video.

How long do UPVC windows last?

+
UPVC windows are designed for durability and low maintenance, often lasting 25 to 35 years or more with proper care. We back our windows with a comprehensive 10-year guarantee covering frame colour stability, shape retention and impact strength, giving you confidence in their long-lasting quality.
