To meet the requirements for means related to the air permeability of the building, HOPPE has developed an AEV seal , named after the test which characterizes the air , water and wind tightness of joinery.
Perfectly invisible, the foam sealing insert which is integrated into the outer plate of the handle, thus considerably reduces thermal bridges and water and air leaks:
- An AEV trim on wide plate 300M-D reduces leak rate by 27 times : Classification A*4 E*1050
- An AEV trim on narrow plate 300LMSGL-D reduces leak rate by 20 times : Classification A*4 E*5A
All handles in the Hamburg line come with a 10-year warranty on their mechanical operation and are of European manufacture.
