Reduce climate change and energy costs with our latest innovation. New windows can transform the look of any home, and they are a great investment too. In our wide range of double glazed windows, you're sure to find exactly the right style to suit your home and your budget.

Choose from our range of casement windows, tilt & turn windows or sash windows.

  • Our uPVC windows incorporate EcoBrite™ low iron and ClariTherm™ low-emissivity glass to dramatically reduce the valuable heat energy lost when compared to older inefficient window.
  • Each pane of glass in our double glazed units is separated by a hermetically sealed 20mm argon gas filled space for maximum thermal efficiency.
  • We have replaced the traditional aluminium spacer between each pane of glass with Super Spacer®, a non-metallic warm edge spacer bar which is 950 times less conductive, thus virtually eliminating condensation. This also improves sound insulation by up to 2 decibels, and incorporates dessicants to ensure a dry cavity.
  • Make your choice from hundreds of different styles, shapes, features and colours and glazing options. All of our windows are manufactured individually to order.
  • You'll get unbeatable value with our price promise, special offers and different payment options.
  • Save up to 50% on all windows in our Seasonal Sale.
  • Keep warmth in and noise out with our energy efficient EcoTherm™ double glazing units.
  • Save time and money with low maintenance PVCu frames.
  • Get the latest window security features to keep your home safe. Our casement windows have been approved by the Association of Chief Police Officers and are registered with their Secured by Design initiative. We also hold the coveted BS7950 security standard.
  • We're here to help you with expert guidance from our experienced consultants to make sure that you're delighted with your choice of windows.

When choosing your windows, why not take a look at our uPVC porches? We can provide traditional and classic styles manufactured in tough GRP in a choice of colours to enhance the appearance of your entrance, also providing instant protection for you and your guests from the elements
