Extreme UPVC Sliding Sash Windows

It was at the end of the 16th century that the sliding sash window was born, and this vertically opening design continues to captivate the nation. Featuring two window sashes, one slightly in front of the other, you smoothly slide it up and down and tend to spot the style a lot at period properties.

All sliding sash windows supplied by our Premium Retailers include energy efficient glass as standard and will often outlast the guarantee you receive. You will be given the opportunity to have the windows double or triple glazed and can rely on the glazing and accompanying elements to secure your house.

An extreme number of coloured finishes...

White is the classic colour of Extreme UPVC sliding sash windows, but if you’re open to alternatives, check out the flood of alternative finishes. Every one of them will underline the excellence of the craftsmanship and is easily preserved.

Chartwell Green is a common selection when a homeowner desires a countryside-inspired hue, or they’ll edge towards something like a Matt Black if they want the windows to be a truly formidable sight. Sliding sash windows can always be dual-coloured if you’d like to combine shades externally and internally.

Why choose our double glazed sliding sash windows?

A Premium Retailer will treat you with fairness and respect from start to finish, and the sliding sash windows provided are certain to deliver long-term excellence, warranting your investment.

Unfaltering quality for years to come...

If you delve deep into the sliding sash window frame, you will encounter a multi-chambered profile, notoriously good for restricting heat loss and noise penetration. As a weather and security guard, it’s second to none, and you also get fusion-welded joints and corners for good measure.

The guarantee a Premium Retailer offers is representative of the calibre of the product, and don’t be surprised if it surpasses its estimated lifecycle.

Can you handle the depth of choice?

You’re able to examine and touch the potential handle options for sliding sash windows in a showroom. When in your hand, the artistry involved in their modelling will become clear.

Security is accounted for in each handle as it’s an obvious strike point for thieves, but one that will ultimately be a futile target. A designer will happily guide you through the handle types.

It’s the hardware that completes the sliding sash window...

It could take some time for you to decide how to furnish your sliding sash windows as there are a host of hardware accessories available for our sash window range. There are so many variations of hinges, and pulls, and they all offer something different, both in terms of their appearance and functionality.

Check out a selection hardware available for your new sliding sash windows.

Premium finishes to withstand regular handling...

Selecting a handle is the first step and needs to be followed by the nominating of a colour to adorn it. Depending on the look you’re wanting to achieve, which could be a classic or modern aesthetic, it will steer you towards gold, black, chrome or white hardware.

Handle colour application eradicates the chance of any rotting, flaking or wear and tear manifesting and spoiling the finish, no matter how habitually the handle gets used.

Locate a compatible glass...

Search for a patterned glass that augments the rest of the sliding sash window design and anticipate it transporting maximum light indoors, brightening your home surroundings. Clear glass is anything but playing it safe and we have privacy glazing to disguise rooms from view.

The technology we have at our fingertips at Conservatory Outlet has been exploited to the full so that each glazing design excellently insulates and acts as something of a soundproofing measure. Gather the opinion of an expert designer if you don’t know which glass to get.

Add some extra detail to round it off...

You only get one chance to personalise sliding sash windows, so don’t neglect our offer of having leaded, astragal or Georgian bars incorporated. They’ll infuse further charm into the windows and a tailored touch that observers of your house will appreciate.

From your own personal experience, you’ll recognise that embellishments of this kind really make you stand up and take notice of windows.
