Ceiling Acoustics
Ceiling isolation is as important to the noise control as the floor isolation system. The concept behind both is to create a "MASS-SPRING-MASS" assembly. KEENE BUILDING PRODUCTS has successfully trained contractors in floor noise system installation and solved the "buildability" issue for the top sideof the assembly. The bottomside remains a weak link. Acousticians and architects design ceiling systems properly but many problems occur in the field. Ceiling details do not work without close supervision.
Problems exist with:
1. Short circuiting of resilient channels with 1.25” screws
or longer
2. Over dimpling screws and connecting the gypsum board
to the structural joist.
3. Resilient flange “riding” the structural joists
4. Gypsum wall board in contact with structural walls
5. Gypsum wall board in contact with gypsum ceilings
6. Resilient channels in contact with structural walls
The ACOUSTICAL ASSURANCE product line was developed to address all of these. RC Assurance and SPACE Assurance are cost effect products that take the difficulty out of ceiling isolation. RC Assurance acts as a nail flange that positions the resilient channel properly and prevents all of the short circuiting common in the field. SPACE Assurance creates the space required around the perimeter of the ceiling while eliminating the caulk detail commonly forgotten by contractors. For the cost of a nice family meal new owners will forget they have neighbors.
