Not normally, but there are certain restrictions. You can find out more from the Government’s Planning Portal.

A drive to have extremely well-insulated, draught-free homes has meant we have reduced the amount of air movement around our homes. A certain amount of water vapour is unavoidable particularly around kitchens and bathrooms, but simple measures like opening windows when possible, using extractor fans and choosing night vents for bedroom windows helps to keep things manageable.

Firstly, don’t panic. This isn’t a fault with the windows but happens when the external air temperature has risen faster than the temperature of the exterior surface of the glass. The moisture in the warm air condenses on the cool surface. It looks odd, but it’s a sign that the insulation provided by your windows is working well – the heat is staying indoors and not getting as far as that exterior glass surface.

It’s very simple. Wash the sections down with a mild detergent and lubricate the hinges. Our step by step aftercare guide will show you how.

You’ll be pleased to know that as the market’s matured, most of the problems have cleared up. Look out for industry certifications like CERTASS or FENSA and always check that any guarantee you’re offered is insurance backed. If you deal with one of our Approved Installers, you’ll be in safe hands. We’ve carefully vetted every one of them.

Frame and glazing unit design is so advanced now that it’s possible to achieve A+ rated energy performance with double glazing. Adding an extra pane of glass may help in a home that’s very well insulated, where there are large expanses of glass, or for homes in exposed locations, but the extra layer can reduce the effect of passive solar gain. We’d advise talking to one of our Approved Installers to help you decide.

Yes. Our windows and doors can last for more than forty years and are recyclable up to ten times. Compare that to timber that needs noxious preservatives and paints to stop it degrading. PVC-u also has much better insulation qualities than timber, enabling homes to stay warmer with less heating. Our PVC-u products are made entirely in the UK and we’ve been awarded BES6001 for the responsible sourcing of our raw materials.

A layer of tough, durable foil is permanently bonded to a base profile. The base itself may be coloured by using UV-stable pigments in the manufacturing process.

The answer depends on several factors, including the existing glazing you have and the size of your property. The Energy Saving Trust is an independent body that gives typical savings for a range of home improvements. You can find their website here.
