INSTALLATION PARAMETERS
SECTION 1.00
INSULATION
In all cases a minimum of 1 ⁄ 2"
thick perlite or high density wood
fiber board insulation will be
installed as a buffering layer. Other
insulations are acceptable for use
within these systems provided the
insulation manufacturer’s specifications
and BITEC’s specifications
are followed. See the General
Requirements SECTION 6.02 of
this manual.
Insulation must be used with all
systems unless its use has been
waived by BITEC’s Technical
Services Department.
SECTION 2.00
BASE SHEETS
AND PLY SHEETS
Unless otherwise specified all
base and ply sheets will be
installed using hot asphalt as per
BITEC’s published requirements
which determine the type of
asphalt to be used, asphalt application
rate, and asphalt application
temperature. See the General
Requirements SECTIONS 1.02,
1.03 and 1.04 of this manual.
Under no circumstances will any
Type IV or Type VI Ply Sheet be
mechanically attached. Under certain
conditions, however, the G2
base sheet called for in the schedule
may be mechanically attached.
Allowance for this must be preapproved
by BITEC’s Technical
Services Department. For parameters
involving mechanically
attaching G2 base sheets refer to
SECTION 2.02, on pg.17 of this
manual.
According to The NRCA
Roofing and Waterproofing
Manual:
“...plies shall be embedded
into a fluid, continuous applica-
tion of asphalt. The asphalt shall
be applied in such a way that at
no place will felt touch felt. All
plies of felt shall be broomed into
place as they are applied to aid
in adhesion ...”
SECTION 3.00
CAP SHEET
Cap sheet shall be installed as
per specifications given in the
General Requirements SECTIONS
2.03 and 2.04, pgs.17-18 of this
manual.
SECTION 4.00
SPECIFICATIONS
AND DETAILS
Primary consultation for this
information shall come from this
book, and The NRCA Roofing and
Waterproofing Manual.
All applicable publications shall
be consulted before work begins.
Some details for BUR-MOD systems
are included in the following
section of this manual. These
details are simply variations of the
details used for modified bitumen
systems.
Typically, for BUR-MOD systems,
all Modified Bitumen Details
may be adapted to be used with
BUR-MOD Systems.
This is generally accomplished
by using the base and/or ply
sheets in lieu of the base and/or
interply membrane of the modified
bitumen system.
For any specific details not
shown, contact BITEC Technical
Services Dept. at (800) 535-8597.
