Slimline Aluminium Windows
With a large range of style options available, our slimline casement windows provide a versatile choice for any glazing project. Often selected for their sleek contemporary aesthetics, our narrow aluminium frames mean a larger glazed area, allowing more natural light to flood in and better views.
Our high-quality aluminium windows feature high-security multi-point locking, have been tested to PAS 24 standards and are certified under the Secured by Design scheme. With thermally broken frames and high-performance glazed units, U-Values are as low as 1.2 W/m²K.
On top of their excellent performance, AluFold windows can be customised with plenty of colour, design and configuration options to suit any requirement.

Why choose our Slimline Aluminium Windows?
Aluminium slimline windows are ideal for replacing old timber windows as well as replacing steel-framed windows. A truly versatile option, aluminium windows give your project, whether it be a new build or a renovation, a stylish and energy efficient alternative to these materials.
Modern aluminium frames also have many advantages over standard uPVC windows. Thanks to its strength and durability, aluminium offers a much longer lifetime for newly installed windows, providing both you and the customer with total peace of mind.
Paired with much better thermal performance and improved security, it’s no surprise aluminium windows are becoming the preferred choice for glazing projects all over the UK.
Multiple Configuartion Options
We offer a range of configuration options to suit a wide variety of opening, hanging and aesthetic requirements.
A side hung window is the classic choice, whereas top hung aluminium windows will offer added security and weather protection. Dummy sash windows provide a more sympathetic option for traditional styles and French casement windows allow for totally unobstructed views, the choice is yours.
The AluFold Standard
There’s nothing ‘standard’ about the AluFold Standard. All of our aluminium windows are supplied with high-performance Low-E soft-coat, toughened, double glazed units with a warm edge spacer bar.
Glazing options
- Our slimline aluminium windows are internally glazed with 28mm glazing thickness
- Internally or externally glazed options are available to accommodate low and high rise projects
- Available double glazed or triple glazed depending on your requirements
- We also offer premium upgrades for enhanced security, enhanced sound insulation and UV fade protection
- For more aesthetic upgrades, choose from inset Georgian bars and additional glass options such as a clear, textured, tinted or satin finish
Inspired by colour
Whether your project calls for statement aluminium windows in bold, daring tones or a more timeless, reserved palette, with AluFold anything is possible.
All of our aluminium window and door profiles are powder coated to ensure protection against the elements and prolong the lifetime of the windows, but this also creates limitless customisation options.
