sills, sweeps & weatherstrip

Sun Mountain distributes a selection of high-quality door sills, sweeps and weatherstrip, generally used on exterior door applications. Our standard options include:

Adjustable Oak Sills

Sun Mountain distributes Pemko® aluminum door sills, with an oak threshold which can be adjusted to create a secure seal to the bottom of the door. Both inswing and outswing adjustable sill options are available.

Non-Adjustable Wood Sills

Sun Mountain offers non-adjustable wood thresholds for openings with limited exposure to the elements.

ADA Sills

Saddle thresholds for ADA compliance or where an adjustable sill is not desired, for example, in a wine room with a temperature/humidity control system.

Auto Door Bottoms

Mortised and mounted into the bottom edge of the door, our Pemko® auto door bottoms recess into the door when open and drop down to the sill to create a tight seal when the door is closed. Auto door bottoms are particularly useful with non-adjustable wood or ADA sills.

L-Shaped & Surface Mount Sweeps

Sun Mountain's L-shaped and surface mount sweeps feature drip caps to direct water away from the door unit. We recommend sealing the top edge of the sweep with a bead of silicone at time of installation, to prevent moisture from seeping between the sweep and the door.

Weatherstrip

Weatherstrip is a durable foam rubber material used to seal the side and top edges of an exterior door, to limit air transfer and exposure to outside elements. The weatherstrip is usually mounted in the kerf, or slot, in the stop of a rabbeted jamb, used for exterior applications.

In addition to our industry leading standard solutions, Sun Mountain can provide other sill, sweep and weatherstrip options to meet nearly any need.
