3.6 THERMAL INSULATION INSTALLATION
A. General: Install insulation concurrently with metal panel installation, in thickness indicated to
cover entire surface, according to manufacturer's written instructions.
B. Blanket Roof Insulation: Comply with the following installation method:
1. Over-Framing Installation: Install in accordance with the industry guidelines found in
North American Insulation Manufacturers Association (NAIMA) MB-316.
C. Long Tab Banded (LTB) Filled Cavity Roof Insulation System.
1. Inspect materials for damage, proper sizes, and quantities upon delivery. Store materials
in a dry secure manner. Notify carrier and laminator of any damaged material, improper
sizes, or shortages immediately upon delivery.
2. Precautions: Long Tab Banded (LTB) Filled Cavity Insulation System does not act as fall
protection. When installing the Long Tab Banded Insulation System; the Contractor,
Builder, Erector, and Insulation Installer must meet Federal and State OSHA safety and
fall protection standards.
3. Banding Installation:
a. Install banding perpendicular to purlins to create a support system for insulation.
Cut banding in lengths long enough to run from eave to eave, or eave to ridge,
depending upon roof design. For gabled buildings, add extra length to
accommodate irregular roof geometry.
b. Spacing:
1) For purlins spaced 60 inches (1524 mm) on center, space banding a
maximum of 30 inches (762 mm) on center.
2) Cut enough banding to accommodate spacing.
c. Attach banding to bottom of eave strut and to each purlin using minimum 1/2 inch
(13 mm) TEK screws. Pull banding as tight as possible to keep all subsequent runs
parallel.
4. Lower Layer - Long Tab Faced Insulation Installation:
a. Preparation: Organize insulation provided.
1) Faced insulation rolls are custom laminated to specific length and width to fit
each purlin space. Each roll will have a "roll tag", indicating its correct
location. Use correct roll of insulation for each location.
b. Install faced insulation layer between and parallel to purlins.
1) Unroll insulation into cavity between purlins, on top of the metal banding.
13600- 12 (ASI #1)
Prefabricated Metal Building System Components
Nelson + Morgan, Architects Flush Truck Storage Expansion
NMA 18023 Issued for Bidding and Construction April 4, 2019
2) Extend long tabs over top of each purlin, orientated such that tabs from
adjacent runs are overlapping to create a continuous vapor retarder. For
critical applications, tape or seal overlapping tabs with a suitable tape or
sealant.
3) Do not pull tabs so tight that they cause the lower edges of the insulation to
pull away from the sides of the purlins.
4) At End Wall: Peel insulation back from facing approximately 6 inches (152
mm) to 12 inches (305 mm), and remove to create an external tab that can
be attached to the rake angle with tape or sealant.
5) At Internal Purlin Bracing: Ensure that insulation is not excessively
compressed. In cases where the bracing will "substantially compress" the
insulation, temporarily remove bracing to allow the faced insulation to be
installed, and then replace the bracing. In applications where bracing
removal is not practical, insulation and facing can be cut to fit around the
bracings as follows:
a) Determine where insulation will need to be cut to fit the bracing.
b) Cut the entire width of the fiberglass and slit the facing tab to the
depth of the brace to accommodate the bracing offset (distance from
top of bracing to purlin's lower flange) on the purlin. Do not cut facing
completely from edge to edge. (Example: If bracing is located 3
inches (76 mm) above the bottom flange of the purlin, cut the full
width of the fiberglass and slit the facing tab starting 3 inches (76 mm)
beyond each edge of the fiberglass, leaving the remainder intact.)
c) After insulation is installed, seal facing from the bottom with a suitable
tape to encapsulate the bracing.
6) Install the faced layer of insulation in the entire width of the roof slope before
installing the top layer of unfaced fiberglass, thermal spacer blocks (where
applicable), and roof sheets.
5. Installation of Top Layer of Unfaced Insulation and Roof.
a. Unroll unfaced insulation perpendicular to purlins, making certain there are no
gaps between edges of adjacent runs.
b. Where it is necessary to splice the unfaced insulation, overlap the ends
approximately 1 inch (25 mm) to 2 inches (50 mm) , before installing roof panels as
follows:
1) Standing Seam Roofs: Install roof clips and spacer blocks, and attach roof
panels. Care should be taken to ensure thermal spacer blocks remain in
place directly above the purlins.
2) Plan installation to ensure there is no exposed insulation at the end of a
work day or at the onset of inclement weather.
a) Only install insulation as far out as can be covered in one day or as
weather permits.
b) Do not leave any insulation exposed to the elements overnight; the
system is not designed to support the added weight associated with
heavy rain or snow.
c) Erector/Installer assumes responsibility for all materials once on site,
and therefore should protect insulation from getting wet.

D. Blanket Wall Insulation: Install in accordance with the industry guidelines found in North
American Insulation Manufacturers Association (NAIMA) MB-316.
3.7 CLEANING AND PROTECTION
A. Repair damaged galvanized coatings on galvanized items with galvanized repair paint
according to ASTM A 780/A 780M and manufacturer's written instructions.
B. Touchup Painting: After erection, promptly clean, prepare, and prime or reprime field
connections, rust spots, and abraded surfaces of prime-painted structural framing[, bearing
plates,] and accessories.
1. Clean and prepare surfaces by SSPC-SP 2, "Hand Tool Cleaning," or by SSPC-SP 3,
"Power Tool Cleaning."
2. Apply a compatible primer of same type as shop primer used on adjacent surfaces.
C. Touchup Painting: Cleaning and touchup painting are specified in Section 099113 "Exterior
Painting" and Section 099123 "Interior Painting."
D. Metal Panels: Remove temporary protective coverings and strippable films, if any, as metal
panels are installed. On completion of metal panel installation, clean finished surfaces as
recommended by metal panel manufacturer. Maintain in a clean condition during construction.
1. Replace metal panels that have been damaged or have deteriorated beyond successful
repair by finish touchup or similar minor repair procedures.
E. Doors and Frames: Immediately after installation, sand rusted or damaged areas of prime coat
until smooth and apply touchup of compatible air-drying primer.
1. Immediately before final inspection, remove protective wrappings from doors and frames.
F. Windows: Clean metal surfaces immediately after installing windows. Avoid damaging
protective coatings and finishes. Remove excess sealants, glazing materials, dirt, and other
substances. Clean factory-glazed glass immediately after installing windows.
