Weather Seals

Hangar door weather seals are sized by three measurements, and all three have to match before the seal will do its job. We stock EPDM weather seal in 1/16 in., 1/8 in., and 3/16 in. thicknesses, in widths from 4 in. to 18 in., plus brush seal for the gaps a compression seal cannot close. Shipped from our warehouse in Ocala, Florida.

How to size a replacement weather seal

Measure your existing seal rather than estimating from the door size. The same opening can take a different profile depending on how the retainer is built, so the old seal is the only reliable reference. If the seal is already gone, photograph the retainer and the door edge and we will identify the profile.

Why EPDM for hangar doors

EPDM stands up to UV and temperature swings better than most sealing rubbers, which matters on a door sitting in direct sun for years. The nylon-inserted rip-stop layer resists tearing at the fastener line and minimizes swelling, so the seal holds its profile instead of distorting and pulling away from the frame.

Brush seal for the gaps EPDM cannot close

Compression seals need a reasonably clean, even surface to seal against. Where the frame has shifted, the threshold is uneven, or two leaves meet at an imperfect joint, brush seal fills the gap without needing a flat mating surface. It also tolerates dust and grit better, which is why it shows up on agricultural and industrial buildings more often. Many doors use both: EPDM along the straight edges, brush seal wherever the gap is irregular.
