New UL test program successfully completed

We are excited to announce the successful completion of our latest UL test program to include ducts within the ceiling space of our floors.

With the latest round of tests, we now have unprotected and protected duct penetrations included directly in our UL and ULC listings for Composite TotalJoist (UL G555 and ULC I525).

This allows customers to reduce or eliminate bulkheads by running HVAC through the floor plenum. With our advanced 3D modelling software, we can coordinate with the architect and mechanical to pre-plan hole locations in our joists to accommodate duct runs and any other services.

We are constantly working to give our customers more options and to make our floor systems the most accommodating in the market. Stay tuned for there is more exciting news to come!
