Hidden under the ceramic colour lies the secret to Lumi’s strength - energy efficient triple glazing that has been structurally bonded to an internal core of high strength, glass-fibre reinforced profiles. This intelligent piece of engineering is the first of its kind on the market, bringing all the design benefits of frameless glazing with all the strength, security and internal styling of more traditional windows and doors.
The 50mm triple glazing is made from 6-4-4 toughened glass, insulating the home against both cold and noise. The flush glazing completely hides the glass-fibre double rebate stormproof frame, offering exceptional U-values and unparalleled weather protection. We can also supply this triple glazed unit with two panes of low emissivity glass filled with argon gas for enhanced energy efficiency.
Lumi bi-folds might look like and behave like Lumi windows and doors, but they work slightly differently. Their 62mm triple glazed insulated glass unit is structurally bonded to a twin seal thermally broken aluminium frame with insulating foam inserts. However, they are one of the most energy efficient bi-folds on the market with excellent U-values. And they have achieved burglar resistance of WK/RC (DIN EN 1627) with Schüco multi point lock system with shoot bolts.
