required, flame spread and smoke developed ratings and distance of insulation

[2.2 VAPOR RETARDER AND DAMPPROOFING
NOTE:
1. Determine the need for a water vapor retarder and its required permeance
value based on a project and climate specific moisture analysis. For guidance
see ASHRAE Handbook of Fundamentals, Chapter 20, "Thermal Insulations and Vapor
Retarders;" ASTM C 755, "Selection of Vapor Retarders for Thermal Insulations;"
and MIL-HDBK-1011/1, "Tropical Engineering" (for humid climates). The computer
Program "MOIST" which is on CCB, is a user friendly tool based on hourly weather
data that provides information on moisture content of materials and on the duration
of high moisture content excursions. Traditionally, vapor retarders were considered
materials having a permeance of 5.72 x 10-8 g/Pa.s.m2 1 perm (grain/h*ft2*in.Hg)
or less. However, that value may not be adequate for the particular construction
or climate and in some instances a much lower value should be specified.
2. Vapor retarders, where required, can be provided as membranes or, alternatively,
vapor retardant finishes labeled by manufacturer as having a water vapor permeance
of no more than the required value can be used. Alternate materials include:
Paints, vinyl wall coverings, or foil-faced gypsum board. Specify these in Sections
09 90 00, PAINTS AND COATINGS, Section 09 72 00, WALLCOVERINGS, or Section 09
29 00, GYPSUM BOARD, respectively and delete all paragraphs and references relating
to vapor retarders from this section.
3. A vapor retarder is only effective if it prevents diffusion of water vapor
as well as the passage of moisture laden air through openings and around material.
Accordingly, proper installation to assure air tightness by sealing of joints,
tears, and around utility penetrations is as important as proper selection of
water vapor retarder materials.
4. Vapor retarders not only retard movement of water vapor into building envelope
cavities, but also retard drying out of moisture that may have infiltrated the
cavity. Accordingly, use vapor retarders only where their need is indicated
by the moisture analysis.
2.2.1 Vapor Retarder in Frame Walls and Roofs
[a. 0.15 mm 6 mil thick polyethylene sheeting conforming to ASTM D 4397 and having a water
vapor permeance of 5.72 x 10-8g/Pa.s.m2 one perm or less when tested in accordance with ASTM E 96/E 96M
.]
[b. Membrane with the following properties:
Water Vapor Permeance: ASTM E 96/E 96M: 5.72 x 10-8 g/Pa.s.m2 [1] [_____] perm

PART 3 EXECUTION
3.1 EXISTING CONDITIONS
Note: For retrofit projects, inspect facility to determine conditions which
may adversely affect execution of work or create safety hazard. Identify relevant
conditions on the drawings and, if required, develop additional specification
sections for corrective actions. Conditions that warrant investigation:
1. Discolorations or mold growth indicating previous water leaks.
2. Heat producing devices, such as recessed lighting fixtures, chimneys, and
flues.
3. Faulty electrical systems:
(a) Lights dimming or flickering
(b) Fuses blowing
(c) Circuit breakers tripping frequently
(d) Electrical sparks and "glowing" from receptacles
(e) Cover plates on switches and outlets warm to touch.
Before installing insulation, ensure that all areas that will be in contact with the insulation are dry and free
of projections which could cause voids, compressed insulation, or punctured vapor retarders. If installing perimeter
or under slab insulation, check that the fill is flat, smooth, dry, and well tamped. If moisture or other conditions
are found that do not allow the proper installation of the insulation, do not proceed but notify the Contracting
Officer of such conditions.
3.2 PREPARATION
3.2.1 Blocking Around Heat Producing Devices
Unless using insulation board that passes ASTM E 136 in addition to the requirements in Part 2, install non-combustible
blocking around heat producing devices to provide the following clearances:
a. Recessed lighting fixtures, including wiring compartments, ballasts, and other heat producing
devices, unless certified for installation surrounded by insulation: 75 mm 3 inches from outside
face of fixtures and devices or as required by NFPA 70and, if insulation is to be placed above
fixture or device, 600 mm 24 inches above fixture.
b. Masonry chimneys or masonry enclosing a flue: 50 mm 2 inches from outside face of masonry.
Masonry chimneys for medium and high heat operating appliances: Minimum clearances required
by NFPA 211.
c. Vents and vent connectors used for venting products of combustion, flues, and chimneys other
than masonry chimneys: minimum clearances as required by NFPA 211.
f. Gas Fired Appliances: Clearances as required in NFPA 54.
g. Oil Fired Appliances: Clearances as required in NFPA 31.
Blocking is not required if chimneys or flues are certified by the Manufacturer for use in contact with insulating
materials.
3.3 INSTALLATION
3.3.1 Insulation Board
Install and handle insulation in accordance with the manufacturer's installation instructions. Keep material
dry and free of extraneous materials. Observe safe work practices.
3.3.2 Electrical Wiring
Do not install insulation in a manner that would sandwich electrical wiring between two layers of insulation.
[3.3.3 Cold Climate Requirement
Place insulation to the outside of pipes.
]3.3.4 Continuity of Insulation
Butt tightly against adjoining boards, studs, rafters, joists, sill plates, headers and obstructions. Provide
continuity and integrity of insulation at corners, wall to ceiling joint, roof, and floor. Avoid creating any
thermal bridges or voids.
NOTE: Foil sided board reflects heat. Indicate on drawings the side on which
the foil is to be faced. Coordinate use with mechanical designer.
3.4 INSTALLATION ON WALLS
3.4.1 Installation using Furring Strips
Install insulation [between] [on] members as recommended by insulation manufacturer.
3.4.2 Installation on Masonry Walls
NOTE: Use the first paragraph below for insulation on the outside or inside
of masonry walls. Use the second paragraph for insulating individual masonry
units within their hollow cores. Insulating the cores only can lead to thermal
bridges and condensation at the web locations of the masonry units.
[Apply board directly to masonry with adhesive or fasteners as recommended by the insulation manufacturer. Fit
between obstructions without impaling board on ties or anchors. Apply in parallel courses with joints breaking
midway over course below. Put ends in moderate contact with adjoining insulation without forcing. Cut and shape
as required to fit around wall penetrations, projections or openings to accommodate conduit or other services.
Seal around cut-outs with sealant. Install board in wall cavities so that it leaves at least a nominal 25 mm
one inch free air space outside of the insulation to allow for cavity drainage.]

* NP: Not Permitted
** Perimeter Insulation is not required in weather regions 8 and 11 where there are less than 3000 Heating Degree
Days (65 degrees F).
Install perimeter thermal insulation where heated spaces are adjacent to exterior walls or slab edges in slab-on-grade
or floating-slab construction.
3.6.1 Manufacturer's Instructions
Install, attach, tape edges, provide vapor retarder and other requirements such as protection against vermin,
insects, damage during construction as recommended in manufacturer's instructions.
[3.6.2 Insulation on Vertical Surfaces
Install thermal insulation [as indicated.] [on exterior of foundation walls] [on grade beams] [partially] [below
grade] [and] [on edges of slabs on grade.] Fasten insulation with [adhesive] [or] [mechanical fasteners].
][3.6.3 Insulation Under Slab
Provide insulation horizontally under [entire] slab on grade [for a distance of [_____] mm feet from the edge
of slab] [as indicated]. [Turn insulation up at slab edge, and extend full height of slab.] Install insulation
on top of vapor retarder and turn retarder up over the outside edge of insulation to top of slab.
][3.6.4 Protection of Insulation
Protect insulation on vertical surfaces from damage during construction and back filling by application of protection
board or coating. Do not leave installed vertical insulation unprotected overnight. [Install protection over
entire exposed exterior insulation board.] [Provide protection extending at least 300 mm one foot below grade.]
][3.7 VAPOR RETARDER
Apply a continuous vapor retarder as indicated. Overlap all joints at least 150 mm 6 inches and seal with pressure
sensitive tape. Seal at sill, header, windows, doors and utility penetrations. Repair punctures or tears with
pressure sensitive tape.
][3.8 ACCESS PANELS AND DOORS
Affix insulation to all access panels greater than 0.1 square meter one square foot and all access doors in insulated
floors and ceilings. Use insulation with same R-Value as that for floor or ceiling.
