Thinline Sill

Thinline Sill

Ideal for projects where a continuation of flooring from the indoors to the outdoors needs to appear virtually seamless. Staggered tracks expose a slim channel on which the panels roll, with the finished floor installed between them.

Water Barrier Sill

A weep system and an interior leg available in different pressure ratings and sizes (1.5″, 2″, and 2.6″ for various performance requirements) helps safeguard against water intrusion. For additional protection, the legs of each sliding panel penetrate the track to keep out dust and debris.
Flush Sill

Flush Sill

An interior and exterior sill height of 0.75″ lines up with most interior flooring for a smooth transition to the outside. Weep holes allow water to drain away from the door while the back leg of each sliding panel discourages dust and debris.

Water Management Sill

For seamless flow from inside to outside, our new water management sill offers a level floor finish with an internal drainage system, for a flush look with optimized water performance. Like our Thin Line Sill, the Water Management Sill will allow for continuous flooring installation between the tracks, for a cohesive appearance and improved accessibility while maintaining water control within the system.
