ACHIEVING GRADE 1 INSTALLATION STANDARDS MULTI-LAYER REFLECTIVE INSULATION FOR
MASONRY WALL APPLICATIONS
INSTALLATION INSTRUCTIONS
Fi-Foil’s installation instructions are detailed
and if followed, should provide a high
quality installation. The instructions for
each product can be found on the Products

insulation.
Typically, the framing or furring has been
installed 16” or 24” on-center prior to the
start of installation.
The insulation should be attached to the
face of furring strips (metal or wood),
expanded and cover the cavity with no or
minimal exposed block showing.
HOW DO RATERS INSPECT MULTI-LAYER INSULATION?
GRADE 1 INSULATION – MINOR DEFECTS
Grade 1 installation requires that the insulation material is installed with the direction of the
framing. Most framing is installed vertically except windows or doors which often are framed
horizontally on the walls.
To attain a rating of “Grade 1”, wall insulation will cover almost the entire cavity – only minor
defects (2% or less of the area is not insulated such that the building envelope (wall) is visible
from the building’s interior).
For building code compliance, insulating materials with a flame spread rating greater than 25,
the insulation facing should be in substantial contact with the drywall (insure that the product
has been adhered to the face of the framing – no inset stapling).
Coverage: Make sure the insulation
covers the entire wall cavity and is
attached securely with staples
approximately every 4” to 8” or
glued, and/or tape tap is secure at
both sides, top, and bottom.
Facing Side / Reflective Side: The
paper side should be facing the
inside of building – the reflective side
should face the block wall.
