Abstract
Es wird eine Anti-Droehn-Folie zur Anbringung auf der Aussenseite einer Dachflaeche beschrieben. Erfindungsgemaess sind eine erste Folienschicht (1) und eine zweite Folienschicht (2) vorgesehen, die in einem vorgegebenen Abstand zueinander gehalten sind und einen nach aussen abgeschlossenen Hohlraum (3) begrenzen, wobei der durch die Folienschichten (1, 2) begrenzte Hohlraum (3) mit einer schwingungsadsorbierenden Fluessigkeit (4) gefuellt ist.

 

DE 102006008787 A1 UPAB: 20070914 NOVELTY - The foil has two foil sections (1, 2), which are held at a pre-set distance to each other by a connecting bar and quilt and borders a hollow space (3) that is closed outward, where the hollow space is filled with a vibration-absorbing liquid (4) such as gel. The bar or quilt connecting the foil sections runs in several directions, where the foil sections, bar, quilt and vibration -absorbing liquid are transparent. The vibration-absorbing liquid contains a material, which exhibits a reversible changing translucence depending on temperature or radiation intensity. USE - Used for attaching on an outer side of a horizontal or slight inclined roof surface e.g. glazing, that is utilized as a room closing unit, glass dome or diaphragm-structure or a building surface. ADVANTAGE - The foil sections are transparent, thus the transparent components such as glazing, light coupler and diaphragm are dammed against high sound level caused during strong precipitation of rain and hail without impairing the function of the glass or the diaphragm with respect to the light permeability of the glass or the diaphragm.
