Kawneer Storefront Door Weatherstripping

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.

• Bottom Brush Sweeps – Flexible nylon bristles seal the gap beneath the door while allowing the entrance to swing freely.
• Bottom Vinyl Sweeps – Flexible vinyl provides a continuous barrier beneath the bottom rail.
• Neoprene Bottom Sweeps – Flexible rubber-style sealing material for commercial storefront door bottoms.
• Leading-Edge Weatherstripping – Replacement channel weatherstripping for the vertical leading edge of compatible Kawneer doors.
• Bottom Sweeps with Rain Caps – Combination assemblies designed to provide a bottom seal while helping divert water away from the bottom of the entrance.

Kawneer Bottom Door Sweeps

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.

Kawneer Brush Door Sweeps

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.

Vinyl & Neoprene Storefront Door Sweeps

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.

Kawneer Leading-Edge Channel Weatherstripping

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.

Kawneer Bottom Sweeps with Rain Caps

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.

Why Replace Worn Storefront Door Weatherstripping?

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.

How Do I Choose the Correct Kawneer Weatherstripping?

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:

• Commercial storefront door width
• Door height when replacing vertical weatherstripping
• Existing brush, vinyl or neoprene seal type
• Gap between the bottom of the door and threshold
• Sweep holder dimensions
• Required visible seal length
• Mounting configuration
• Clear aluminum or dark bronze finish when applicable

Pair Your Kawneer Door Sweep with a Commercial Threshold

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.
