CHOOSING YOUR FRAME STYLE
FIND YOUR PERFECT STYLE
Each style is designed to maintain a consistent aesthetic across Endurance Aluminium’s range of products, including casement windows, French doors, bifolding doors and more.
Heritage
The stepped profile features a pronounced, layered appearance, inspired by traditional steel window designs. It creates depth and character in the frame by having a visible step between the sash and the surrounding frame.
Architectural flush
Retains the flat-faced, minimalist aesthetic but aligns the sash and the outer frame for a more streamlined appearance.
Heritage flush
The stepped flush profile maintains the stepped aesthetic but aligns the sash and the outer frame. This creates a smoother, more seamless look while retaining some traditional design elements.

THE FLUSH FIT ADVANTAGE
Enhanced Aesthetics: Our flush-fitting windows and doors offer a sleek, modern look, blending seamlessly with wall surfaces for a minimalist design. This refined aesthetic enhances both contemporary and traditional properties, delivering a clean and uncluttered appearance that elevates the overall visual appeal.
Maximised Natural Light: Flush-fitting options reduce the visible frame, creating the impression of larger windows and a brighter, more open interior. This design choice is perfect for homeowners looking to amplify natural light and foster a sense of spaciousness throughout their home.
Enhanced Thermal Performance: Flush-fitting designs can contribute to thermal efficiency by minimising air leakage and creating a tighter seal between the frame and wall. When combined with our InsuLock technology, a flush fit further enhances energy efficiency, keeping your home warmer and more sustainable.

Frequently Asked Questions
Are aluminium frames better than uPVC?
Yes, in terms of longevity, aesthetics, and structural integrity. Aluminium frames have a lifespan of 30–40 years, significantly longer than standard uPVC. Because aluminium is inherently stronger, it allows for much slimmer sightlines and larger panes of glass, maximizing natural light without compromising on security. While uPVC was historically seen as more thermally efficient, modern Endurance systems with InsuLock technology and thermal breaks have bridged this gap, offering superior performance across the board.
Is an aluminium window frame good?
An aluminium window frame is an excellent choice for any modern or traditional home. They are highly resistant to the UK weather, meaning they won’t warp, rot, or flake over time. Endurance Aluminium frames are precision-engineered to be both lightweight and incredibly strong, providing an added layer of security. They are also 100% recyclable, making them a more sustainable green choice for eco-conscious homeowners.
Can I replace a door frame without replacing the door?
While technically possible, it is not recommended for a high-performance installation. For an Endurance door to achieve its full security (PAS 24) and thermal efficiency ratings, the door leaf and frame must be precision-aligned. Replacing just the frame often leads to issues with the weathertight seals and locking mechanisms. To ensure your home remains secure and draught-free, we recommend replacing the door and frame as a single, engineered unit.
How much does it cost to replace an entire door frame?
The cost of replacing a door frame depends on the specific dimensions, your chosen frame profile (such as our Stepped or Flush designs), and any additional glazing like sidelights. To get a 100% accurate price for your project, we recommend using our online door designer or contacting an approved Endurance Installer Partner for a bespoke, no-obligation quote tailored to your home.
Is an aluminium door frame good?
Yes, aluminium door frames are among the best on the market for durability and performance. Unlike timber, they do not require regular painting or varnishing, and unlike uPVC, they do not expand or contract significantly in extreme temperatures. An Endurance Aluminium door frame provides a robust, low-maintenance foundation that ensures your door operates smoothly for decades while maintaining a sleek, high-end appearance.
