uPVC Windows and Doors

The popularity of uPVC double glazed windows and doors has continued to grow enormously over the past few years. Homeowners are drawn to this window and door material which provides a winning combination of sleek aesthetics and a great performance. For double glazed windows and doors that'll last the test of time, choose uPVC.

uPVC double glazed windows are an excellent replacement for outdated designs and timber windows. uPVC is a naturally insulating material, providing great energy efficiency for your home and potentially reducing your need for heating bills. This could save you massive amounts in winter. You can also forget about any large amounts of maintenance; uPVC windows only require a simple wipe down every now and again to stay looking their absolute best.

For a front entrance door that will give you years, if not decades, of all round great performance, uPVC is the obvious choice. Full to the brim with weatherproofing, uPVC front doors will keep the elements far away from the interior of your home. They also offer noise reduction qualities, with double glazed front doors cutting out potential sound disturbances from outside, preserving peace and quiet within your home. uPVC residential doors are also highly customisable, with an astounding range of colours and woodgrain options to help match your uPVC door to your home.

Aluminium Windows and Doors

Aluminium windows are perfect for homeowners who want to inject their house with style instantly. Slim sightlines and elegant design make aluminium windows incredibly elegant additions to any home, regardless of property style. You can customise your aluminium double glazed windows further, too. With a massive range of colour options, styles and designs, you'll have complete flexibility. All of our aluminium double glazing is made to measure as well, ensuring the perfect fit for your home.

Aluminium bifold and patio doors are more than just an entranceway; they’re an attractive feature for your home. They seamlessly join your home’s interior and exterior for a smooth transition between space. With large glass panes, aluminium bifold and sliding patio doors let natural light flood into your home, making your space seem large, warm and inviting to any guests. You can forget about them sticking too; modern technology has refined the opening of aluminium doors, making for a silky smooth opening even after years of use.


The perfect way to add space to your Croydon home, conservatories offer excellent space extension and add value to your property. Unlike in the past, modern insulation and energy efficient materials ensure that you’ll be able to use your conservatory space all year round as well. Our range has a timeless appearance and will blend seamlessly with your home to make sure there’s a consistent look across your whole property. You'll also enjoy complete peace of mind; with a selection of state of the art locking features in place, your extension will be safe and secure.
