Sealing element for sealing a flute of a fluted metal deck

Abstract

A sealing element is useful for sealing a flute of a fluted metal deck. The sealing element includes a body and a coating surrounding the body. The body has a predefined geometry adapted to seal the flute, wherein the body is flexible and the cross sectional area of the body in a direction perpendicular to the flute axis is larger than the cross sectional area of the flute the sealing element is designed to seal.

1 : A sealing element for sealing a flute of a fluted metal deck, comprising:
 a body, and   a coating surrounding the body,   wherein the body has a predefined geometry adapted to seal the flute, wherein the body is flexible and a cross sectional area of the body in a direction perpendicular to g flute axis is larger than g cross sectional area of the flute which the sealing element is designed to seal.   
     
     
         2 : The sealing element according to  claim 1 , wherein a shape of the cross section of the body corresponds to a shape of the cross section of the flute. 
     
     
         3 : The sealing element according to  claim 1 , wherein the body comprises mineral wool. 
     
     
         4 : The sealing element according to  claim 3 , wherein the body comprises multiple layers of mineral wool. 
     
     
         5 : The sealing element according to  claim 1 , wherein the coating comprises a thin plastic film. 
     
     
         6 : The sealing element according to  claim 1 , wherein the coating is stretchable. 
     
     
         7 : The sealing element according to  claim 1 , wherein rigidity of the coating is lower than rigidity of the body. 
     
     
         8 : The sealing element according to  claim 1 , wherein the body is tightly enveloped by the coating. 
     
     
         9 : The sealing element according to  claim 1 , wherein the coating is provided in a form of a bag, wherein the volume of the bag is larger than the volume of the body. 
     
     
         10 : The sealing element according to  claim 9 , wherein the coating is not air-tight. 
     
     
         11 : The sealing element according to  claim 3 , wherein the body comprises a formaldehyde-free mineral wool. 
     
     
         12 : The sealing element according to  claim 4 , wherein the multiple layers are oriented parallel to the cross sectional area of the body.
