Dual "H" Perimeter Seals

This door is equipped with our patented dual Super "H" door sealing system.  It consists of a dual compression type perimeter seal.  Compression seals typically offer higher acoustical ratings.  The seal is composed of a felt/neoprene combination that forms a tight perimeter seal.  Dual compression seals are used on our highest rated acoustical doors.

Super "H" Door Bottom

Overly's super "H" door bottom is the only choice for unbeatable sound control. Always used in conjunction with our cam-lift hinges, this door bottom compresses tightly against the floor. We recommend smooth level sealing surfaces for this door bottom. Uneven or abrasive flooring may prematurely wear the door bottom. A smooth raised threshold is recommended when using this door bottom.

UL Fire Ratings

In addition to acoustical testing, Overly has successfully tested this product to the latest UL fire test standard UL10C/UBC 7-2 (positive pressure).
