unless asphalt is used in installing the insulation.
**************************************************************************
Where indicated, provide edge strips in the right angle formed by junction
of roof and wood nailing strips that extend above level of roof. Install
edge strips flush against vertical surfaces of wood nailing strips. Where
possible, nail edge strips to adjoining surfaces. Where installed against
non-nailable materials, install in [heavy mopping of asphalt or set in
heavy coating of asphalt roof cement] [an approved adhesive].

PROTECTION
3.5.1
Protection of Applied Insulation
**************************************************************************
NOTE: Insert appropriate Section number and title
in the blank below using format per UFC 1-300-02.
**************************************************************************
Completely cover each day's installation of insulation with the finished
roofing specified in [_____] on same day. Do not permit phased
construction.
Protect open spaces between insulation and parapets or
other walls and spaces at curbs, scuttles, and expansion joints, until
permanent roofing and flashing are applied. Do not permit storing,
walking, wheeling, or trucking directly on insulation or on roofed
surfaces. Provide smooth, clean board or plank walkways, runways, and
platforms near supports, as necessary, to distribute weight to conform to
[indicated live load limits of roof construction] [a [_____] kg/sq. m psf
live load limit]. Exposed edges of the insulation shall be protected by
cutoffs at the end of each work day or whenever precipitation is imminent.
Cutoffs shall be 2 layers of bituminous-saturated felt set in plastic
bituminous cement [or single ply] [or EPDM membrane] set in roof cement.
Fill all profile voids in cut-offs to prevent entrapping of moisture into
the area below the membrane. Cutoffs shall be removed when work is resumed.
3.5.2
Damaged Work and Materials
Restore work and materials that become damaged during construction to
original condition or replace with new materials.
3.6
INSPECTION
**************************************************************************
NOTE: When justified by the amount or criticality of
the insulation and roofing involved, and when
requirements for a roof insulation technician are
not established for the Contractor Quality Control
organization, the following requirement will be
added at the end of this paragraph: "A roof
insulation technician, responsible directly to the
Contractor and experienced in the installation of
roof insulation and related work, shall perform the
inspection functions and be on the site whenever
roof insulation operations are in progress."
**************************************************************************
The Contractor shall establish and maintain an inspection procedure to
assure compliance of the installed roof insulation with the contract
requirements. Any work found not to be in compliance with the contract
shall be promptly removed and replaced or corrected in an approved manner.
