To meet the resource requirements related to the air permeability of the building, HOPPE has developed an AEV gasket, from the name of the test that characterizes the watertightnessAir, To theWater and Wind 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 benefit from 10 year warranty on their mechanical functioning and are from European manufacturing.
