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.

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.

  Minimal Frames have been outstanding throughout the process, from planning to install and aftercare. At all times their communication has been top-notch; fast and effective. Quality of the glazing itself is excellent, the installation process was pain free and the windows and pivot door look incredible. They’ve been really strong on aftercare too, checking in that all works well and correcting a very minor issue quickly. I really cannot fault any part of our experience and wouldn’t hesitate to use them again and recommend to others.

  Bob and his team have taken on our tricky glass extension installation, embraced its complexity and delivered it to perfection. It truly is a stunning addition to the house. The team that worked on site was extremely pleasant; always on time, quiet and polite. The project turned out to be long for its complexity, but the final result was worth the wait. We are very pleased with the outcome and hope it will keep us cool even in the heat of summer. Thank you MFP team! With kind regards, Emil and Narmina

  Bob and Minimal Frame have stepped in to help sort out problems with another glazing company. He has kept us well informed throughout and has worked tirelessly to deal with the manunufacturers to get the doors delivered and the install started. We were 90% done by Christmas which was a huge relief. I've found Bob to be straightforward, transparent and responsive and am very grateful for his help fixing our previous issues. Additionally, his install team have been highly professional and meticulous in getting the install right.
