The distinctive window in the center of
the AlpaJoist eliminates the need for old-fashioned
bridging, reducing the possibility of squeaking.
The patented window system allows for fast
and efficient strongback installation. Long
timbers slide quickly through the center
openings, and are then easily nailed in
place (at the desired 90 degree angle).
Strongback installation is recognized as
the most effective bridging method for vibration
reduction because it introduces a continuous
stiffness in the transverse direction of
a floor system.
Super Strong
The AlpaJoist is comprised of more wood
than the standard I-Joist because its openings
are re-inforced with double flanges, top
and bottom. The double-flangue configuration
provides additional stiffness at the critical
section. While most joists are made so that
openings can be cut into them, the AlpaJoist
is the only one with engineered openings,
guaranteed to maintain the structural integrity
of the joist for the life of the home.
Reduces Labour
The engineered openings in the AlpaJoist
eliminate the need for trades to drill through
a series of joists before commencing installation
of plumbing, heating and electrical systems.
They simply thread the wires, pipes and
ductwork through the patented window.
Saves Time
AlpaJoist's engineered window of opportunity
appeals to volume builders wanting to speed
up site completion. Plumbers, electricians
and installers of heating systems can get
in and out of an AlpaJoist home very quickly.
The AlpaJoist is the most efficient I-Joist
ever manufactured.
Eliminates Bulkheads
When you use the 11 7/8" or larger
AlpaJoist, ductwork may slide quickly and
easily through the engineered openings,
eliminating the need to drop the ductwork
under the joists. This eliminates basement
bulkheads.
