Installation
1. There are two ways to cut
STYROFOAM Ag Board.
One way is to use a straight
edge and a utility knife or
handsaw. Or, use a knife to
score the STYROFOAM Ag
Board. Then break the board
over the edge of a table or
sawhorse.
2. Attach STYROFOAM Ag Board
perpendicular to framing,
spanning at least three framing members with insulation
board joints breaking over
framing or meeting the roof
edge. Penetrate separate
wood and metal framing 1"
with a corrosion-resistant
fastener and poly washer,
such as QUIK Cap. When
fastening to metal, Buildex
Multi-Diameter Insulation
Teks or equivalent (with
minimum 1-1/4" poly washers)
are advised.

INSTALLATION INFORMATION
AGRICULTURAL
For more than 50 years,
STYROFOAM* Ag Board extruded
polystyrene insulation has
helped agricultural building
owners control the building’s
indoor environment and protect
its contents, whether livestock,
crops or equipment. In addition
to its exceptional insulating
value, STYROFOAM Ag Board
resists moisture infiltration,
withstands high-pressure cleaning
and reduces the potential for
moisture condensation within
the wall.
The easy-to-install STYROFOAM
Ag Board uses shiplapped edges
to create a secure joint that
does not require taping, saving
considerable installation time.
Materials

Installation Procedures for
STYROFOAM Ag Board Insulation
Figure 2
End-joint gaps that are greater
than 1/8" should be filled with
spray foam such as GREAT
STUFF Gaps & Cracks sealant
or equivalent to keep a continuous air infiltration barrier
and to help ensure maximum
thermal efficiency across the
board joints. To increase the
moisture effectiveness of the
board joints, apply STYROFOAM
All-Purpose Tape over the
sprayed board joints.
4. For maximum protection
against moisture and air infiltration, seal the board end
joints with STYROFOAM AllPurpose Tape. Use a squeegee
or soft paint roller to press the
tape firmly to the joint. Cut
tape with a knife or scissors.
Do not tear tape.
3. Lock the shiplapped edges
together.

NOTICE: Changes to the International Residential Code require the installation of a weather-resistive barrier (WRB) within most exterior wall assemblies in residential construction. The following Dow insulated sheathing products qualify as a WRB when installed according to the installation instructions developed for “installation o f foam sheat hing as a weather-resistive barrier”: STYROFOAM DURAMATE* Plus, STYROFOAM
Residential Sheathing, STYROFOAM Tongue and Groove, STYROFOAM Square Edge, STYROFOAM Residing Board, THERMAX*, TUFF-R* and Super TUFF-R and therefore do not require the use of a building paper
or a housewrap as a WRB. When a WRB is not needed, these Dow foam sheathings may be installed according to standard installation instructions for foam sheathing from Dow. Be sure products and installation
instructions meet code requirements for your particular location. Note: STYROFOAM WEATHERMATE* and WEATHERMATE Plus housewraps have already qualified as weather-resistive alternatives to the prescribed
felt (see Evaluation Reports NER 593 and NER 640 for approved alternative).
NOTICE: No freedom from any patent owned by Dow or others is to be inferred. Because use conditions and applicable laws may differ from one location to another and may change with time, Customer

COMBUSTIBLE: Protect from high heat sources. Local building codes may require a protective or thermal barrier. For more information, consult MSDS, call Dow at 1-866-583-BLUE (2583) or contact your
local building inspector. In an emergency, call 1-989-636-4400.
Building and/or construction practices unrelated to insulation or housewrap could greatly affect moisture and the potential for mold formation. No material supplier including Dow can give assurance that
mold will not develop in any specific system.
