Setting the standard

Kömmerling’s new PremiDoor 88 claims to ‘set a new standard for performance in large span lift and slide patio door systems’ in terms of energy efficiency, sound reduction and weather performance.

This latest development from Kömmerling is based on an installation depth of 88mm, with a flush mounted five-chambered sash and frame design. The typical ‘U’ value of the door is 1.2 W/m2K, though a Passivhaus standard of 0.8 W/m2K can be achieved. It’s also capable of a width of 6.5m, with a sash height of 2.9m with just two sashes.

Sound insulation values as high as 45db are achieved with PremiDoor 88 and it’s already been tested by ift Rosenheim for its tightness against driving rain achieving a rating of 750 Pa, with similarly impressive results for wind loading. PremiDoor 88 is available in white, more than 40 woodgrains and coloured foils and with the AluStar exterior cladding system.

In addition, PremiDoor 88 is available with the ‘pioneering’ proCoverTec surface technology launched last year at Fensterbau, offering a slightly textured satin finish in either one face or on both faces and through the glazing rebate. There are 22 different colour options.

The PremiDoor 88 system has also been designed and engineered with a ‘Lux’ variant which does without the need for a fixed sash. Instead, it features a fixed mullion and large fixed glazing, fitted with aluminium glazing beads attached to the outside. The results are particularly slender sightlines of 95mm in the side frame and true to its name, a greater passage of light.

Kevin Warner, head of sales and marketing at Kömmerling commented: “Our latest PremiDoor 88 clearly sets the benchmark for performance on all criteria and reflects the engineered nature of our products. We believe that our premium product range has set the bar high in the UK glazing industry and further product launches this year will support our proposition.”
