About us
Frameless Glass Curtains Ltd are specialist manufacturers of the world's only truly frameless dual and triple glazed door and window systems. Our patented technology eliminates visible vertical mullions entirely, creating a seamless glass wall appearance with maximum light and unobstructed views. Designed and manufactured in the United Kingdom, and now available in California through our authorized dealer network.
What makes our frameless glass doors special?
Our patented glass spacer bar replaces the conventional aluminum spacer found in every other glazing system. Where other doors meet in the middle, you see aluminum. Where ours meet, you see glass meeting glass — no metal, no mullion, just uninterrupted views.
This is not a slim-frame system marketed as minimal. It is a genuinely frameless system, protected by patents in the UK, USA, EU, and Australia. No other manufacturer in the world offers dual or triple glazed frameless doors.
The result is a glass wall appearance that conventional aluminum bifolding doors and sliding doors simply cannot achieve — with panels up to 51" wide and 118" high, a flush-mountable 5mm threshold, and each panel sliding and stacking independently for complete flexibility.
Engineered in the UK, perfected since 2009
In 2009, our founder Gary Beresford set about improving what was then a basic European concept — single-glazed frameless doors running on Teflon tracks, with limited durability and a one-year guarantee. The US market demanded more.
Substantial investment followed. We designed new hardware, engineered glass units to enhance the frameless concept, and built for long-term reliability.
Over the years, we have continuously refined the product. Innovations include a proprietary wheeled system enabling wider and taller panels than any other bifolding door on the market, a multi-point compression locking system certified to PAS 24 enhanced security standards, and triple-glazed options for the most demanding energy requirements.
95% of the components in our doors are manufactured at our UK factory. The vast majority are designed and engineered in-house — including the patented glass spacer bar, the single most important innovation in the system. This is not an assembled product built from off-the-shelf parts. Every component is engineered to work together as a complete system.
Certified for the US market
Our products have been independently tested and certified for the US market:
- NFRC certified — U-Factor of 0.30 (dual glazed) and 0.27 (triple glazed)
- NAFS tested — structural integrity, water penetration, air leakage, and forced-entry resistance tested at Intertek, Fresno
- Title 24 — tested and proven to help dealers, designers and builders achieve Title 24 compliance
A proven track record
We have completed hundreds of installations across the UK, Europe, the Caribbean, and North America since 2009 — from private residences to some of the most recognizable names in the world.
Our corporate clients include Manchester United, Aston Martin, McDonald’s, Audi, and The World Residences at Sea. We have installed our frameless systems in hotels, restaurants, schools, churches, and cruise ships. Our residential portfolio spans coastal properties, countryside homes, and contemporary new builds across multiple countries and climates.
Every system we manufacture for the US market is built to the same exacting standards, in the same factory, by the same team.
