Frameless, Flush, and Full of Light – A Revolutionary Window System for Modern Living

Experience a completely new perspective on glazing with MFP75 Lumi Flush Glazed Windows. Designed for those who appreciate clean lines and uninterrupted views, this innovative system features a fully flush glazed surface with no external frames in sight. The result? Wall-to-wall glass that floods your home with natural light while delivering unbeatable energy performance, durability, and a sleek, minimalist finish.

Built for Beauty, Engineered for Performance

Innovative Triple Glazing Meets Seamless Aesthetic

Discover the advanced construction behind Lumi’s flush glazed windows. Every layer is carefully designed for strength, energy efficiency, and noise insulation — from the low iron, triple-glazed glass and structural adhesives to the energy-saving warm edge spacer and stormproof frame. The result is a frameless glazing solution that doesn’t just look exceptional — it performs beyond expectations in every season.

Designed for Homes & Commercial Spaces

Versatile Flush-Glazed Windows in Any Shape, Size, or Finish

The MFP75 Lumi range is ideal for both residential and commercial use, offering flush triple-glazed windows that can be tailored to almost any design. Choose from a wide range of opening styles — including side-hung, top-hung, open-out and parallel casements — all with a completely flat, uninterrupted glass profile.

Behind the minimalist styling lies advanced engineering: triple glazing structurally bonded to a glass-fibre reinforced internal core for strength, energy efficiency, and total design flexibility. It’s a first-of-its-kind flush glazing system that combines the beauty of frameless design with the performance and security of traditional aluminium windows.

Custom Finishes Inside and Out

Durable Exterior Colours & Seamless Interior Styling

Each Lumi flush glazed unit features a ceramic colour band fused into the glass at 700°C — delivering a bold, fade-resistant finish in your choice of eight contemporary shades. With no external frame, maintenance is minimal and visual impact is maximised.

Internally, you can create a fully coordinated aesthetic with matching finishes across trims, sills, and window boards. Choose from eight premium interior styles, including four elegant wood grain effects. Whether you’re enhancing a modern home or refining a high-end development, Lumi offers design cohesion without compromise.
