Composite deck supplier should be responsible for connection of lightweight material
to deck.
3. Metal "acoustical" roof deck with rigid insulation and a structural standing seam
metal roof system. Consider using this system over the hangar bay.
Consider using one or more of these systems as applicable.
Other types of roof systems based on cost and energy savings can be considered.
Select the most suitable roof systems from the following criteria:
(1) Very low slope (minimum of 6 mm per 305 mm (1/2 inch per foot)). Where roof slopes
are 6 mm per 305 mm (1/2 inch per foot), decks should be stiff enough to prevent ponding,
and a built-up roof should be smooth surfaced.
(2) Sloped roofs (25.4 mm per 305 mm (1 inch per foot) or greater). Roofing membrane,
insulation, and moisture protection should be used only on roofs with a slope of 25.4 mm per 305
mm (1 inch per foot) or greater.
(3) Pitched roofs. Insulated metal roof panels should be used. Panels should be pre-
engineered or field-fabricated and filled with blanket or rigid insulation with insulation blocks
over purlins.
Hangar Doors
Hangar doors shall be one of the following types:
Horizontal Sliding Hangar Doors
Hangar doors should be a series of insulated, horizontal sliding leaves with protected, preformed
(corrugated) metal or sheet-steel siding. Each sliding door leaf should be supported on hardened
wheels rolling on recessed rails with guide rails at the top of the door. Hangar door rail support
system should provide for surface drainage. Intermittent drainage to hangar trench drains should
be at 10 feet 0 inch maximum.
Thresholds should be designed to minimize dirt accumulation or ice buildup at rails. Leaves of
the door should be insulated and should be provided with waterproof weather stripping and
emergency personnel exits as required by NFPA 101, Life Safety Code. The hangar doors
should be hand-crank operated or electric motor operated. For electric motor operation, drives
may operate leaves independently or in groups of three with drives on the end leaves and a
pickup mechanism for the center leaf. The use of a cable system for the pickup mechanism
should not be considered due to the extra maintenance required to keep the cable system in good
operating condition. Each drive unit should have a release mechanism, and the doors should be
