the high roof over the OH space through a secured access panel or hatch, to
prohibit unauthorized passage. Built-up roofing, insulation, and moisture
protection should conform to the applicable guide specifications listed at the
Whole Building Design Guide DoD page (http://dod.wbdg.org/.)
3-10.1
Systems to Consider. Consider the use one of the following
systems:
3-10.1.1
Metal roof deck with rigid insulation, smooth surface built-up roof
system or mineral surface modified bitumen roof system.
3-10.1.2
Composite metal deck and lightweights concrete engineered roof
system with smooth surface built-up roof system or mineral surface modified
bitumen roof system. Composite deck supplier should be responsible for
connection of lightweight material to deck.
3-10.1.3
Metal "acoustical" roof deck with rigid insulation and a structural
standing seam metal roof system. Consider using this system over the hangar
bay.
3-10.2
Other Alternatives. Consider using one or more of these systems
as applicable.
3-10.2.1
Other types of roof systems based on cost and energy savings can
be considered.
3-10.3
Criteria to Consider. Select the most suitable roof systems from
the following criteria:
3-10.3.1
Very low slope (minimum of 13 mm per 300 mm (1/2 inch per foot)).
Where roof slopes are 13 mm per 300 mm (1/2 inch per foot), decks should be
stiff enough to prevent ponding, and a built-up roof should be smooth surfaced.
3-10.3.2
Sloped roofs (25 mm per 300 mm (1 inch per foot) or greater).
Roofing membrane, insulation, and moisture protection should be used only on
roofs with a slope of 25 mm per 300 mm (1 inch per foot) or greater.
3-10.3.3
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.
3-11
HANGAR DOORS. Choose one of the following types:
3-11.1
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
