Extreme UPVC Windows

The Extreme UPVC Window from Hazlemere is one of the best performing UPVC windows on the market...

The Extreme Windows collection provides the ultimate solution for improving the look and feel of your home. Designed to the highest specifications, these beautiful windows deliver extreme security, comfort and style, all while backed by our 10-year guarantee for complete peace of mind. The Extreme collection has been designed to meet the latest energy efficiency ratings which ensure these stunning windows not only look great, but they help to keep your house warm in winter while reducing energy costs.

This bespoke range allows you to design the perfect look for your home with a range of eye-catching colours for both contemporary and traditional properties.

The Extreme Collection is only available from select, trusted partners across the country, with Hazlemere exclusively selected to supply the Buckinghamshire, Berkshire, Oxfordshire, Hertfordshire and surrounding areas. Each partner must ensure they provide the highest quality installation standards and operate to the highest integrity. You won’t find our windows available anywhere else, so you won’t be able to get a ‘like for like’ quote from another home improvement company.


Your route to buying the perfect window...

Replacing ageing windows isn’t as easy as you may think. Finding a suitable substitute takes much time and consideration as you need to be absolutely certain that it suits the surrounds and only enhances your property. You may find yourself overwhelmed by the sheer amount of choice you have at Hazlemere but you should never feel daunted by it as we are always here to give you a helping hand. We would never allow you to buy a new window design that doesn’t fit your criteria.

Functionality

It’s very easy to be allured by a pretty looking window but appearances aren’t everything. The way the window functions is of equal importance and after playing around with each available design you may find that you have a preference for a certain type of functionality. We have windows that open from the side or top, slide vertically, and open via a tilt and turn motion; there really is something to suit everyone.

Guarantee

You should never consider buying new windows without a quality guarantee. The last thing you need after buying them is to be left out of pocket because they failed to provide the security you expected of them. Hazlemere offers a fantastic window guarantee so that you’re left fully confident in your purchase. We urge you to read it carefully as it does mention that occasionally some small remedial adjustments will have to be made.
