Marvin Windows and Doors Media Room

Marvin’s sliding patio and sliding French doors now have an innovative option with the addition of the Low Profile Sill.   Just ¾” off the base flooring, the Low Profile Sill provides an easy transition between indoor and outdoor spaces.  Those looking for a clean look will appreciate the Low Profile Sill’s flush profile.

The Low Profile Sill offers exceptional performance and beauty. Certified as DP40 on most sliding doors, the Low Profile Sill is strong and durable with the performance of a higher sill.

Its low profile is also ADA-compliant, adding ease to home living for those disabled or aging in place.

This sill is made from Ultrex®, a durable pultruded fiberglass and has an interior oak liner. It can be ordered with all current product and design options on Marvin sliding French and sliding patio doors.

The Low Profile Sill is a design exclusive to Marvin Windows and Doors. Now homeowners don’t have to choose between performance and looks—the Low Profile Sill shows only the beauty of the door, while remaining strong and secure.  And with today’s aging population, the Low Profile Sill is an important safety consideration, offering a flush threshold.  For those using wheelchairs or walkers, the Low Profile Sill is an ADA-compliant door, making home living a little easier.

John Simpson of Marvin Windows and Doors says, “The Low Profile Sill’s clean, flush look is perfect for today’s indoor-outdoor living trend.  In the past, taller thresholds were necessary for top performance, but Marvin’s inventive engineering has made the Low Profile Sill look good and perform just as well as a traditional sill.”
