NOTE

Care must be taken to ensure R-12 fiberglass insulation
does not ‘fluff up’ more than 3.5" and R-20 fiberglass
insulation does not ‘fluff up’ more than 5.5". The Ultra-Fin
System will not function properly if the air flow below the
Ultra-Fins is blocked.
+
NOTE
+
For all Ultra-Fin installations, ensure the insulation rests
flush with the bottom of the joists, and that a minimum
2" air space is always maintained between the Ultra-Fins
and the insulation.
Refer to the insulation diagrams in this section to confirm
that you have allowed sufficient air space.

Building codes prohibit you from drilling in certain parts of
joist members. Before you drill, refer to Drilling Section in
this manual for guidelines on where you are permitted to
drill joists. Incorrect drilling may result in structural failure
of joist members. Also check with your appropriate local
building authority.

Ultra-fins installed with SideKeys
In new construction above small
crawl spaces, you can choose to
install Ultra-Fin from above, before
the floor sheathing is installed.
Using the SideKey hanger, you can attach the Ultra-Fins and hang
the tubing at the time, following these simple steps:
Lap two Ultra-Fins over
a section of tubing and
insert one SideKey.
1
Fasten the Ultra-Fins
together by twisting
the SideKey 90°.
