Sliding sash windows are an enduring classic…

Sliding Sash Windows have been around for generations and continue to be a prominent feature in UK properties. Their success can be put down to when they are fitted in a home, they really are such an improvement, energy efficiency and maintenance wise, over old wooden box sash windows. Sash Windows are multi-functional as they can be opened vertically upwards and downwards, as well as inwardly, so that when it comes to ventilating your property, they are ideal.

UPVC Sash Windows

“A” rated Sash Windows from Premier Windows give you the option of tilting the sash inwards for gradual ventilation and ease of indoor cleaning. Contemporary vertical sliding Sash Windows will improve your home aesthetically and practically. Each Sash Window comes with a 10-year guarantee for total peace of mind.

There’s nowhere else you can get EXTREME sash windows

Our EXTREME collection accomplishes the goal of fulfilling the highest security standards. In an EXTREME sash window, there are 11 visible locking points and that’s why it’s 3 times more secure than a standard sash window.

  • 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.
