Structural test pressures shown are for both positive and
negative loads.
3. For projects which require security windows,
refer to AR 190-51 "Security of Army Property at
Unit and Installation Level" and Section 13958
FORCED ENTRY RESISTANT COMPONENTS.
4. For projects which require fire-rated windows to
meet UL and NFPA requirements, specify a steel type
unit as specified in Section 08510 STEEL WINDOWS;
aluminum windows are not approved for this purpose.
5. For basements, projected windows shall be the
inward swinging (project-in) type.
6. The hardware specified is typical for each
window type. Refer to manufacturer's catalog for
optional hardware selections.
7. Double glazed windows with a specified
Condensation Resistance Factor (CRF) may be
specified for occupied buildings such as barracks,
medical facilities, administration buildings, etc.
The CRF is a rating number, obtained under test
conditions, that predicts the point at which
condensation will occur on either the glass or
frame. Where outside temperature and inside
humidity indicate that condensation may be a
problem, the appropriate CRF should be inserted in
the space provided.
