A stretchable thin plastic film and a double faces adhesive tape are mountable on exterior surfaces surrounding a building window or door to provide an external weather barrier. One side of the adhesive tape is adapted for mounting on a wide variety of external mounting surfaces at temperatures as low as 40°F., and the plastic film is mountable on the adhesive on the other side of the tape at the same low temperature. The two adhesives have different adhesion strengths which enable the adhesive tape to be adhered to the mounting surface without separation therefrom during the stretching and adhering of the plastic film to the opposite side thereof and which adhesion strengths, with the film so stretched and adhered, provide for the film to be maintained against separation from the adhesive tape and the adhesive tape maintained against separation from the mounting surfaces under adverse weather conditions including gusting winds, rain and temperatures at least as low as 0°F. for a period of at least six months. The plastic film has sufficient memory to enable it to return to a taut, wrinkle free disposition fillowing distension of the film by the impingement of wind and rain thereagainst.

An exterior weather barrier for an opening through a building wall and which opening is bounded exteriorly of the building by exposed mounting surface means, said weather barrier including adhesive tape means resistant to ultraviolet radiation and comprising adhesive carrier means having opposite sides, a first pressure sensitive adhesive on one of said sides for adhering said tape means to said mounting surface means about said opening and a second pressure sensitive adhesive on the other of said sides and facing away from said mounting surface means when said tape means is adhered to said mounting surface means, and said weather barrier further including stretchable plastic film means of sufficient surface area to cover said opening and overlie and adhere, in an initial stretched, taut, wrinkle-free condition, to said second adhesive on said tape means, said film means being resistant to ultraviolet radiation and having a plastic memory acting to constantly return said adhered film means to said initial stretched, taut, wrinkle-free condition from further stretched and distended conditions thereof caused by adverse outdoor weather conditions, said first adhesive having a peel adhesion strength of at least about forty ounces per inch, said second adhesive having a peel adhesion strength of at least about twice the peel adhesive strength of said first adhesive, said film means and said first and second adhesives being mountable on said mounting surface means at a temperature of the latter of from about 40°F. to about 100°F., said plastic film means being flexible and crack and tear resistant at a temperature at least as low as 0°F., and said first and second adhesives providing adherence without separation from the corresponding one of said mounting surface means and film means at a temperature at least as low as 0°F. A weather barrier according to claim 1, wherein the resistance of said plastic film means to stretch is lower than the shear strength of the bondings of said plastic film means to said mounting surface means by said adhesive tape means.
