USG Radar 2 ft. x 2 ft. Square Edge Ceiling Panel

Our take on the USG Radar 2 ft. x 2 ft. Square Edge Ceiling Panel

The USG Radar is a 2 ft. x 2 ft. drop-in acoustic ceiling panel made of fiberboard with a non-directional white finish. It carries an NRC of 0.77, which puts it among the better sound-absorbing panels for offices, basements and home theaters. The non-directional pattern means installers do not have to line up grain direction in the grid. The listing describes 2 ft. x 2 ft. panels in a count of 8, though the spec sheet also lists 2' x 4' tile dimensions, so confirm the size before ordering.

Questions and answers

What does NRC 0.77 mean for a ceiling panel?

NRC is a 0 to 1 sound absorption score. At 0.77, the Radar absorbs roughly three-quarters of the sound energy that hits it, which is strong for a basic drop-in panel and noticeably better than thin economy boards.

Is this panel 2x2 or 2x4?

The product name and color listing say 2 ft. x 2 ft., but the spec sheet lists 2' x 4' tile dimensions. Check the carton label or ask the seller to confirm the actual panel size before ordering.

Can I install these in a standard drop ceiling grid?

Yes. They are drop-in panels for a suspended 15/16-inch grid. The non-directional pattern means you do not need to rotate panels to match a grain.

Is it rated for commercial ceilings?

Yes. It carries a Class A fire rating and low VOC emissions, which are the usual requirements for commercial and multi-family spaces.

How many panels do I need for a 100 sq. ft. room?

A 2x2 panel covers 4 sq. ft., so 100 sq. ft. needs about 25 panels, plus a few spares for cuts and breakage. A 2x4 panel covers 8 sq. ft.

When is the best time to buy ceiling panels?

Prices on ceiling panels move little, but check the price history here for dips. Buying full cartons rather than singles usually gives the lowest per-panel cost.
