Abstract
A weatherseal has a stiffener and a foam profile. A first portion of the foam profile is connected to the stiffener. A second portion of the foam profile is joined to the first portion at a hinge. The first and second foam profile portions have inner surfaces facing substantially towards each other and outer surfaces facing substantially away from each other. The foam profile defines at least one continuous elongate lumen. A portion of the foam profile has a resin coating.

A weatherseal comprising:
- a base structure;
- a hinged foamed TPE V-shaped profile comprising:
- a triangularly shaped lower leaf secured to the base structure and having a nested triangularly shaped first lumen defined therein;
- an upper leaf having a second lumen defined therein, wherein a profile height is measured from the base structure to a top of the upper leaf;
- and
- a hinge connecting the lower leaf to the upper leaf located approximately 40% of the profile height;
- and
- a resin coating an exterior surface of the TPE V-shaped profile;
- and
- wherein the profile height has a nominal height of about 0.650″, and wherein the weatherseal comprises a compression load deflection of less than about 1.25 pounds per foot, when compressed to a thickness of about ⅜″ at a rate of about 1″/minute.

A weatherseal comprising:
- a stiffener;
- and
- a hinged foam profile comprising an exterior surface at least partially coated with a resin, the hinged foam profile comprising:
- a first portion having a first portion cross sectional area, wherein the first portion is connected to the stiffener and defines a first lumen comprising a first lumen cross sectional area similar to and nested within the first portion cross sectional area, wherein a distance between the first portion cross section area and the first lumen cross sectional area is substantially equal around the first lumen;
- and
- a second portion connected to the first portion via a hinge and having a second portion cross sectional area, wherein the second portion defines a second lumen comprising a second lumen cross sectional area similar to and nested within the second portion cross sectional area.
