Now the perimeter is secure, thanks to Schlegel's Hydrosill threshold system. Seals out water, dust, drafts, and noise.

The HYDROSILL Threshold System joins at the corners with Q-LON door seals to form a compression seal around the entire door perimeter, even the threshold. Its unique Contain-and-Drain system puts an end to water penetration by managing water drainage away from the door.

Superior Test Results
Schlegel has tested dozens of doors for their resistance to driving rain. Without fail, every door equipped with its original threshold and weather seals faied. When we equipped the same doors with HYDROSILL Thresholds and Q-LON door seals, they allowed zero water penetration, no matter how long the tests ran.

Easier to Close
The design of the HYDROSILL Threshold System significantly reduces carpet drag, actually reducing the force necessary to shut the door.

Simple Installation
The HYDROSILL Threshold System has no adjustable parts. Complete installation instructions are included, and an instructional CD-ROM is also available.That means you get your job done, with no callbacks necessary.

Durable, Proven Performance
HYDROSILL Thresholds pass all industry water and air test requirements, and they are certified by Architectural Testing, Inc., for water resistance at a 35 mph wind load for a full three hours.
