Integral Blinds
Our integral blinds offer a sleek and modern alternative to traditional curtains, external blinds, or other window treatments. They are a practical solution for sliding patio doors, bifold doors and French doors as they don’t interfere with the opening mechanism and sit neatly inside the panes of glass. Integral blinds help regulate room temperature, provide privacy, and protect furniture from fading. Offering exceptional protection from the sun’s heat and glare, these blinds stay dust and dirt-free for life.
KEY FEATURES OF OUR ALUMINIUM WINDOWS
INSTALLER FRIENDLY ALUMINIUM WINDOWS

The patented construction method – using threaded screws to bind corners tightly together – helps eliminate misaligned corner issues that can occur on ordinary aluminium frames. This allows each window to be individually hand tuned to perfection.

Frequently Asked Questions
Please take a look at our frequently asked questions, if you can’t find the answer you are looking for please get in touch.
A Eurogroove is a standard feature in aluminium window and door profiles—a specially designed slot that allows for the secure fitting of hardware such as handles, locks, and hinges. It ensures compatibility across different manufacturers and makes installation straightforward and reliable. Using Eurogroove-standard profiles helps improve the structural integrity, security, and overall performance of aluminium windows, while also making maintenance and replacement of hardware much easier.
We supply a wide range of aluminium windows, including casement, French, bifold, and tilt-and-turn styles. While the majority of our work supports trade clients installing residential windows from small windows to large feature windows, we also manufacture fixed and bespoke window designs for commercial projects, delivering quality and precision across every installation.
Aluminium windows are highly durable, low-maintenance, and resistant to rust and corrosion, ensuring long-lasting performance. Their slim, modern frames maximise natural light while offering excellent thermal efficiency and security. With government standards for energy efficiency continually rising—and expected to become even more stringent—aluminium windows are an excellent choice for meeting current and future regulations. Additionally, aluminium is fully recyclable, making it an environmentally responsible option for both homes and commercial properties.
