Click & Forget Clip In Beads

Clip-in beads are also fully available on Aluminium Window Systems. Our clip in bead is unique in that when installed with our market leading profile, installers benefit from both flexibility and ease of installation, dramatically reducing the time of install per pane.

What sets our new bead design apart is the confidence in the sound it makes as it is installed. Simply click it into place without the need for tools or any excessive force where traditionally, glazing would require a time-consuming wedge gasket.

Durable Luxury Hardware

Premium window handles available in five stylish finishes including Polished Gold, Chrome, Satin Chrome, White, and Black. Designed with an ergonomic lever for comfort and a high-security locking system tested to 50,000 cycles, backed by a 10-year guarantee.

The Coastal range features 316 Marine Grade Stainless Steel with a slim, modern design and optional PVD Satin Black finish — delivering strength, corrosion resistance, and sleek style for aluminium windows.

Colour Options & Bespoke Finishes

Our windows are available in three standard finishes — White (RAL 9016), Anthracite Grey (RAL 7016), and Black (RAL 9005) — plus two dual-colour options for greater design flexibility.

For projects requiring something truly bespoke, any RAL colour can be supplied upon request, allowing you to perfectly match your windows to your architectural vision and project requirements.
