Large areas of glass, slim frames, high energy efficiency: BAU 2017 saw Ensinger exhibit insulbar and in so doing present the solution for delicate, visually appealing systems which simultaneously retain outstanding insulating properties. The lambda value of just 0.18 W/m*K means that Ensinger has succeeded, with the new insulating profile insulbar LO, in achieving a further reduction of around 40% in thermal conduction capacity. The secret lies in its porous, patented material structure. Several microscopically small, closed cavities in the core of the insulating profile provide the significantly greater insulating efficiency.
