What is the difference between 15/16" and 9/16" T-bar grid?

15/16" is the standard commercial grid width offering maximum durability and economic value. 9/16" is a narrower, refined profile that provides a sleek, modern architectural aesthetic with reveal-edge (tegular) acoustic panels.

Do you install seismic bracing on commercial drop ceilings in BC?

Yes. As required by the BC Building Code and CISCA seismic guidelines for Zone 4 seismic regions, we install heavy-duty perimeter retaining clips, 4-way 45-degree splayed aircraft cable/wire bracing, and rigid compression struts at required intervals.

Can T-bar ceilings be combined with drywall bulkheads?

Yes. We frequently frame steel stud drywall perimeter bulkheads and coffer borders that seamlessly transition into central suspended T-bar acoustic grids for high-end retail and office lobbies.
