Traditional charm that will stand the test of time…

Sash windows include one or more moving panels known as ‘sashes’. These simply slide up to open the window. Sash windows are a traditionally styled window that offer a beautiful solution for those looking to complement an old property with the modernity of a well-insulated window, available with Georgian style bars that give a real sense of elegance to a home.

UPVC Sash Windows

You can control the level of ventilation you get to enjoy in your home by simply positioning the sash at the level you want thanks to tilt restrictors.

As well as this, our sash windows are internally glazed and include key locking catches for additional security and peace of mind.

Sash windows that come with EXTREME protection

If proof we’re needed of just how seriously we take security, closely examine our EXTREME sash windows and you will see that everything about the design revolves around security. Containing 11 visible locking points, an EXTREME sash window is 3 times more secure than standard sash designs. 

EXTREME enhanced security with centre VAULTBOLT and multi cam locking technology.

EXTREME enhanced durability with UNIQUE superglide gearbox ensures smooth operation.

EXTREME enhanced COMPRESSION and acoustics with interlocking hinge bolts and optimum weatherseals.

Sliding Sash Frame

Available in welded joints with 45-degree corner welds for a smooth, sleeker finish and mechanical joints to take the design to another level, the 90-degree welds give a more traditional sash window finish.

Ultimate Glass

High performance next generation glass for superb energy efficiency. With acoustic glass to block out the sound of a bust neighbourhood, or patterned privacy glass for a bathroom, we’ll have the perfect solution for you.

Sliding Sash Locking

Secured using a snail cam that is fitted to the top face of the sash. By turning the lever, the cam is released from its keep, giving you the option of either a key-locking or non-locking system.

Sliding Sash Handles

Our handles come in a range of colours to suit your home, they’re built to last with robust materials and quality finishes.

Weather Proofing

Wool pipe strips that provide an excellent layer of defence against the elements. Available with colour-matching wool pile to ensure that every detail of you window matches perfectly.

Versatile Design

As standard, our Sliding Sash Window also comes with a slide and tilt facility, allowing you to clean both the top and bottom sash from inside your home.
Energy efficiency that exceeds normal levels…

Extreme Windows are the strongest performing windows on the market in energy efficiency terms as they have an A+ energy rating as standard. They can cleverly harness the volume of heat your home needs from the sun, whilst also stopping any wanted warmth from escaping.

Your energy bills won’t be as costly as they were, and your home will be warmer than it was too – what more reasons do you need to buy some?

Window buying involves a series of steps and one of the biggest is choosing a window style. After coming to a decision on that, you then need to move on to selecting a coloured finish, glazing and hardware for the windows.

A phenomenal assortment of coloured finishes…

We don’t ever foresee a time when people completely turn their backs on traditional white, but there’s no doubt that tastes have broadened. To meet this demand, the colour palette for the Extreme range is extensive and includes many colours that you would never anticipate seeing in a UPVC window product. The kind of colours we’re talking about include Chartwell Green and a fashionable Grey.

Glass that successfully harmonises privacy and style…

The glass is more than just a focal point in a window. It will also have a bearing on the overall performance of the design. When it comes to choosing the glazing for an Extreme window, think about the level of visibility that you want. You can have a standard clear glass or there’s privacy glass available. Discuss the merits of each glazing type with the team at your local Premium Retailer.

Beautifully crafted handles…

It requires many hours of work and concentration for the craftspeople to skilfully create the traditional and contemporary-styled handles for the Extreme range. Feel the quality every time you use them.

Much of the security in an Extreme window comes from the handle as it has a secure locking system inside it.
