Installation
Guidelines
Orientation
ASTRO-SAFE
duct liner must be installed with the reinforced foil facing
toward the air stream.

Adhesive
Use a Type 1
adhesive that complies with ASTM C 916. All duct surfaces that
will be covered with ASTRO-SAFE must be covered 90% or more with
adhesive. Installation must be neat and tight with no exposed
edges.
Any exposed
edges of ASTRO-SAFE that are not covered with foil must be
coated with adhesive and taped with 2 mil foil tape with acrylic
adhesive, such as ASTRO-FOIL tape.

Mechanical Fastening
In addition to
an approved adhesive, mechanical fasteners that are welded or
impact driven must be used in accordance with HVAC Duct
Construction Stanards Ð Metal and Flexible (SMACNA 1995). Refer
to the following illustration for typical fastener spacing.
Cuts or gouges
in the foil surface can be repaired with 2 mil aluminum foil
tape with an acrylic adhesive such as ASTRO-FOIL Foil Tape. Tape
all seams where edges of ASTRO-SAFE butt together.
