Tallest bifold
Sieger Systems claims to have launched the world’s tallest thermally broken, aluminium bifolding door, available exclusively to IQ Glass in the UK.
The Sieger Super Lux Bi-folding Door is a fully tested bifolding door system, able to achieve opening bifold doors from 3m to 5m tall. The opening heights are possible thanks to the integrated sliding wind post between each bifolding pair.
This latest advance in building envelope design meets the demand for bigger glass units, taller openings and higher performance, the company said. The aluminium profiles contain a full thermal break, allowing the bifolding door to maintain high levels of thermal insulation with typical Uw values from 1.6W/m2K. The system has been fully tested for air permeability, water resistance and wind loading.
Dan Borthwick, commercial manager at IQ, said: “My clients are always asking for taller doors and bigger openings. Normally we can only achieve this with sliding doors. Now we can use bifolding doors to create these double height openings.”
