Sealing system for overhead door
A sealing system for a storage enclosure is disclosed. The sealing system includes a sealing member having a first sealing portion, and a second sealing portion that extends from the first sealing portion. The second sealing portion including a first leg and a second leg. The first leg extends from the first sealing portion at a first angle, and the second leg extends from the first sealing portion at a second angle. The second angle is larger than the first angle.
1. A sealing system for a storage enclosure, the sealing system comprising:
a sealing member having:
a first sealing portion that tapers from a first end to a second end, the first sealing portion shaped for insertion between a door jamb and a frame to create an impermeable seal in a space between the door jamb and the frame, while allowing a leading edge of the door jamb to contact the frame;
a second sealing portion that extends continuously from the first end of the first sealing portion, wherein the first sealing portion and the second sealing portion are made from a compressible foam material, the second sealing portion including:
a first leg extending orthogonally from the first sealing portion, the first leg having a pressure sensitive adhesive for attaching the sealing member to a side surface of the door jamb; and
a second leg extending at an angle between 90 and 180 degrees from the first sealing portion, the second leg having a sealing surface that is configured to be engaged by an overhead door, the sealing surface having a slip seal layer that is waterproof and inhibits sticking and freezing to the overhead door; and
a space defined between the first and second legs when the second sealing portion is in an uncompressed state, the space between the first and second legs being less than 90 degrees when the second sealing portion is in the uncompressed state, and wherein the space is eliminated when the second sealing portion is compressed by an exterior surface of the overhead door pushing against the sealing surface of the second leg.
2. The sealing system of claim 1 , wherein the second leg extends from the first sealing portion by an angle of about 135 degrees.
3. The sealing system of claim 1 , wherein the pressure sensitive adhesive is orthogonal to the first sealing portion.
4. The sealing system of claim 1 , further comprising an insert made of solid material.
5. The sealing system of claim 4 , wherein the insert has an elbow shape and extends between the first sealing portion and the first leg of the second sealing portion.
6. The sealing system of claim 1 , further comprising a backing plate made of solid material.
7. The sealing system of claim 6 , wherein the backing plate is configured to secure the first sealing portion to a side surface of an overhead door.
8. The sealing system of claim 6 , wherein the backing plate is configured to secure the first sealing portion to a side surface of a frame of an opening of the storage enclosure.
9. The sealing system of claim 1 , wherein the sealing system is an extruded component.
