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

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

    USG Donn® Brand CE™ Acoustical Suspension System is the best grid for a Clean Room environment.

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

    Facing the main tee splice place your left hand near the left side of the splice and right hand near the right side of the splice. 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.
