Commercial aluminum entrance doors use different types of weather seals depending on where the gap is located and how the door was originally constructed. This category includes replacement weatherstripping for several common Kawneer storefront applications.
The bottom of a commercial storefront door is one of the most common locations for unwanted air and debris to enter a building. A properly selected Kawneer bottom door sweep closes the gap between the bottom rail of the aluminum door and the threshold while still allowing the door to open and close normally.
Automatic Door and Hardware offers bottom sweeps for common storefront door widths, including 36", 42" and 48" wide commercial doors. Always verify your actual door width and the required seal height before ordering replacement weatherstripping.
Brush-style storefront door sweeps use flexible bristles to fill the irregular gap between the door and threshold. The bristles flex as the door moves, helping create a barrier without excessively restricting normal door operation.
Brush sweeps are an excellent replacement option for commercial entrances where the goal is to reduce air drafts, insects, dust and other exterior debris beneath the door.
For applications requiring a flexible continuous seal, choose from vinyl or neoprene Kawneer bottom sweeps. These flexible sealing materials are designed to extend below the bottom rail and cover the opening between the commercial door and threshold.
Different sweep sizes are available for different gaps. Measure the distance between your existing door bottom and threshold carefully so the replacement sweep provides adequate coverage without creating excessive drag as the door swings.
Weather sealing is not limited to the bottom of the door. Kawneer commercial entrances can also use vertical leading-edge channel weatherstripping to help seal the gap along the edge of the storefront door.
Replacement leading-edge weatherstripping is available for different door heights and finishes. Before ordering, verify the length, profile and finish required by your existing Kawneer entrance.
For exterior commercial storefront doors exposed to weather, a bottom vinyl sweep with rain cap provides additional protection at the bottom of the entrance. The flexible sweep seals beneath the door while the rain-cap profile helps divert water away from the bottom rail.
For the best overall seal, bottom weatherstripping should be paired with a properly fitted commercial door threshold and the appropriate perimeter weather seals.
Commercial door weatherstripping is a wear item. Constant door movement, foot traffic, weather exposure and contact with the threshold can eventually cause the original sweep or seal to become damaged, brittle, torn or missing.
Storefront weatherstripping can look similar even when the dimensions or mounting configuration are different. Do not select a replacement sweep based on appearance alone. Measure your existing door and weather seal before ordering.
Important information to verify includes:
The bottom sweep and threshold work together to close the opening beneath a commercial entrance. If the existing threshold is damaged, excessively worn or missing, installing a new sweep alone may not provide the desired seal.
Inspect both components when servicing an older storefront door and replace worn hardware as necessary for the best fit between the door bottom and threshold.
Automatic Door and Hardware carries a complete selection of Kawneer commercial storefront door parts, including locks, handles, offset pivots, flush bolts, thresholds, door closers, exit devices and other replacement entrance hardware.
