Double Glazing Windows

Refresh your outlook on the world

At St. James Windows, we can help you design your perfect windows and show you what your home will look like. Our windows come aesthetically designed to fit your home, so whether you pick a Tilt & Turn window, a Bay window or any other style from the options we have available, we guarantee a high quality product with lasting results.

Our UPVC Windows are certified A+ rated, Lead-free as standard and are made-to-measure for a perfect fit. We use a Multi-Chamber profile that gives a higher thermal efficiency, with more barriers to prevent heat from escaping, keeping your home nice and warm.

Our High-end Multi-locking system comes with a standard internal beading feature that helps provide more security to your home. The quality of the glass we use and the systems we put in place together make the perfect Double Glazed windows that reduce noise, with a reduction level of up to 45 Decibels.

At St. James Windows we have a standard 15-year Guarantee on all our windows so why not give us a call to see how we can help give your home that long-lasting, great quality transformation.

Windows are the showcase feature of your home. They determine the character and appearance of your property, whether it's a chic apartment, a traditional Victorian terrace or a stylish new-build house.

Color matching is of great importance when considering new windows, and because we manufacture all our PVC at the same facility from the same mix, we can guarantee that our whites and colors will match. Also our unique blend of stabilizers will ensure that no unsightly yellowing will occur to spoil the finish in which we pride ourselves.

It's essential to choose windows that compliment the style of your home, provide long-life protection against the elements and enhance the security of your property.
