Alpa Floor System Inc.

Whisper Quiet
The distinctive window in the centre of the AlpaJoist™ eliminates the need for old-fashioned bridging, reducing the possibility of squeaking. The traditional I-joist requires traditional bridging to hold it securely in place. This means many short sections of timber must be toe-nailed to each joist. Hammering the nails in on such an angle reduces their strength by 17%, increasing the likelihood that in time the nails wil work their way loose and cause squeaking. The AlpaJoist’s patented window system solves that problem by allowing for fast and efficient strongback installation. Long timbers slide quickly through the centre 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-flange 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. Installers simply thread the wires, pipes and ductwork through the patented window.

Saves Time
AlpaJoist’s engineered window 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.

Environmentally Friendly
The AlpaJoist™ is made completely of wood, a renewable resource. Canada’s forests are currently expanding, thanks to a comprehensive re-planting program recognized by the United Nations as one of the best in the world. Wood is also recyclable.

There’s no joist like it!
