Abstract

In accordance with the present disclosure, a method includes applying uncured polyether on the inside perimeter and on a portion of the outside perimeter of the rough opening prior to attaching the sill plate membrane flashing, the left and right jamb membrane flashings, and the head plate membrane flashing to adhere the sill plate membrane flashing, left and right jamb membrane flashings, and head plate membrane flashings to the material forming the perimeter of the rough opening. The method also includes, prior to each step of attaching, forming the sill plate membrane flashing, left and right jamb membrane flashings, and head plate membrane flashing from a precured sheet of polyether material.

1 . A method, comprising:
 attaching a sill plate membrane flashing formed of precured polyether material onto a sill plate of a rough opening formed in a structural membrane;   attaching left and right jamb membrane flashings formed of precured polyether material on left and right sidewalls of the rough opening to overlap at least a portion of the sill plate membrane flashing;   attaching a head plate membrane flashing formed of precured polyether material on a head in the rough opening to overlap at least a portion of the left and right jamb membrane flashings to form a continuous barrier membrane around an entire inside perimeter and an exterior perimeter of the rough opening.   
     
     
         2 . The method of  claim 1 , comprising applying uncured polyether on the inside perimeter and on a portion of the outside perimeter of the rough opening prior to attaching the sill plate membrane flashing, the left and right jamb membrane flashings, and the head plate membrane flashing to adhere the sill plate membrane flashing, left and right jamb membrane flashings, and head plate membrane flashings to the material forming the perimeter of the rough opening. 
     
     
         3 . The method of  claim 1 , comprising, prior to each step of attaching, forming the sill plate membrane flashing, left and right jamb membrane flashings, and head plate membrane flashing from a precured sheet of polyether material. 
     
     
         4 . The method of  claim 1 , comprising attaching the sill plate membrane flashing, left and right jamb membrane flashings, and head plate membrane flashing to the material of the rough opening with uncured polyether and non-metal fasteners. 
     
     
         5 . The method of  claim 1 , comprising forming the sill plate membrane flashing to have a flat base panel to be adhered to the sill plate, an upright back wall and left and right upright sidewalls depending away from the base panel orthogonally in a first direction that would be towards a head plate in the rough opening when installed in the rough opening, and further forming a front panel projecting orthogonally away from the base panel in a direction that is opposite to the back wall and left and right sidewalls.
