Can I Lay Insulation on the Backside of Tiles to Reduce Through-Ceiling Noise and Improve R-value?
Ceilume has developed Soniguard Drop Ceiling Insulation specifically to be used with drop ceiling tiles of all types.
In general, ceiling tiles are not designed to bear any weight other than their own, which is why grid-supported brackets are required when mounting things like recessed can lights and ceiling speakers. The same is true when it comes to the weight of conventional insulation on the back of the tile, whether that tile is made from vinyl, tin, or mineral fiber. Standard insulation will probably cause ceiling tiles to sag over time.
With ultra lightweight, pre-cut Soniguard, sag is not a problem.
Here are four good approaches to improving ceiling R-value and NRC value, and reducing "through ceiling" noise:
- Install Soniguard Drop Ceiling Insulation above your tiles. Itch-free, dust-free, and pre-cut to size, Soniguard will keep your room warmer in the winter, cooler in the summer, and quieter all year long.
- Use rigid insulation that will rest on top of the "spines" of the T-bar grid system. This gives you increased insulation value, but without putting weight on the tiles themselves.
- Insulate the hidden ceiling structure above your suspended ceiling. This insulation might take the form of insulation batts stapled between the rafters or floor joists from which your drop ceiling grid is hung, or of rigid insulation mounted directly to the ceiling structure above the T-bar.
- Use AcoustoTherm Backpanels in conjunction with your Ceilume Ceiling Tiles to increase both R-value and NRC value. AcoustoTherm is the only thermal/acoustic enhancement available for use with Ceilume's translucent lighting panels, and the only solution that is approved for use beneath fire suppression sprinklers.
