This technology prevents heat transfer, keeping your home warmer in winter and cool in summer.

Warmer, Quieter, Safer Aluminium Windows

Ideal for projects where planning or design requires the installation of sympathetic materials, the aluminium Sheerline Prestige range incorporates a thermally efficient and versatile 72-80mm wide system and is available in casement, French, tilt & turn plus fixed window styles. Designed to be in keeping with the modern trend for light, airy interiors, the slim sashes allow more light to flood into your home, creating that important sense of space and tranquillity. There’s a choice of two profile styles to choose from:


This flat faced option has a modern, minimalist aesthetic, for a simple clean look to your home.


Designed to replace and complement listed buildings, warehouses and similar buildings where steel windows have always traditionally been fitted, the step helps to create a slimmer looking frame, while adding character.

Contemporary Flush/Stepped Flush

Both styles are available in Prestige’s standard outer frame or as a ‘Flush’ option that brings both the perimeter and the opening sash perfectly in line with each other.

Perfection Guaranteed

With beautifully slim sightlines, Prestige windows help maximise the daylight entering your home with crisp aluminium detailing creating a defined and architectural look. Manufactured using a patented construction method, threaded screws are used to bind corners tightly together which helps to eliminate misaligned corner issues that can occur on ordinary aluminium frames. This allows each window to be individually hand turned to perfection!

Robust, Sturdy & Tamper-Proof

Providing peace of mind for homeowners and contributing to safer living environments, Prestige’s full depth ‘eurogroove’ offers a high security, multi-point locking system, helping keep you and your home safe and secure. Additional features like unique hinge protectors also help create exceptional levels of security.

What Is PAS24?

PAS24 is a standard of testing to measure the security performance of windows to ensure they can resist a level of attack from an opportunist burglar. And importantly, it’s a quality assured standard that offers buyers confidence when buying an accredited product.

What Does PAS Stand For?

Publicly Available Specification, more commonly known as PAS is a standard set by an industry to ensure all manufacturers in an industry are making and selling products that reach industry benchmark for quality.

PAS24 & New Builds

To comply with building regulations, all new residential builds must demonstrate that their windows have passed the security requirements of PAS24. This makes PAS24 the minimum legal standard that measures the ability of windows and doors in the UK to withstand physical attacks.

Are Prestige Aluminium Windows PAS24:2022 Accredited?

All Sheerline Prestige windows carry PAS24:2022 enhanced security accreditation, so if you’re looking for stylish windows with extra peace of mind as standard – then Just Doors and Windows have your covered!
