q & a

  • How is the load test data collected for ceiling grid?

    Load data and spans are based on simple span tests in accordance with ASTM C635, with a deflection limitation of L/360.

  • How do you remove cross tees without a tool?

    To remove a cross tee, push up on the main tee with your thumbs (where the cross tee is connected) and rotate it until the cross tee pops up and out of the slot.

  • What are the best grids to use in an area that is accessible to moisture?

    The best grids to use in an area accessible to moisture are the Donn® AX™ Acoustical Suspension System or the Donn® ZXLA™ Acoustical Suspension System.

  • What is the standard warranty of grid?

  • What gauge hanger wire is needed to install grid?

    For residential installation 18-gauge wire is required. For commercial installation 12-gauge wire is required.

  • What is the warranty for a system, that uses USG tile and grid together?

    There is a lifetime warranty on any ceiling system that is used in conjunction with our tile and grid. All grid is lifetime when used with USG tile, however not all tile is lifetime when used with USG grid. See complete warranty for details.

  • How is the spacing of wire hangers determined for fire-rated assemblies?

    All systems must be installed and tested in compliance with ASTM C636.

  • When installing grid, what is the minimum clearance needed from the overhead structure?

    Minimum clearance is 3", which allows ceiling tiles to be inserted and removed freely.

  • How do you take main tees apart without a tool?

Using a shearing motion, push with your left hand and pull with your right hand. This disconnects the main tee splice. Be sure to straighten the end tabs before attempting to reconnect.
