The A La Carte approach to specifying RTU noise and vibration control products allows project specific input using a schedule template with a cut and paste menu of component specifications.
The Mix and Match approach allows specifiers the greatest flexibility to easily amend needed treatments as noise sensitivity changes from project to project.
HUSHCORE® BASE™ SYSTEM MODEL HIR-2
Model HIR-2 HUSHCORE® Isolation Rails utilize 2” deflection adjustable springs to fit between the RTU and typical 14” high factory KD curb. Model HIR-2 rails are shipped completely assembled and are NOT a kit. Access ports are located for leveling and periodic spring inspection as required.
HUSHCORE® BASE™ SYSTEM MODEL HIC-2
Model HIC-2 HUSHCORE® Isolation Curbs utilize 2” deflection adjustable springs in a 24” high integrated one-piece completely assembled vibration curb. All springs are accessible for adjustment and leveling with vertically restrained snubbers.
HUSHCORE® DECK™ SYSTEM MODEL DS-32
HUSHCORE® Deck™ Systems are in-curb acoustical treatments available in a range of configurations to achieve tested acoustical performance to meet all project needs. The DS-32 model is rated at STC-32. This solution provides moderate attenuation of RTU radiated noise through the roof deck inside the curb.
HUSHCORE® DECK™ SYSTEM MODEL DS-41
The model DS-41 Deck™ System is a multi-layer composite configuration that achieves excellent performance when used to attenuate RTU in-curb radiated noise. This cost-effective assembly is rated at STC-41 and out performs gypsum board treatments by up to 5 STC points.
HUSHCORE® LINEAR™ SYSTEM MODEL HLM-100N
The HUSHCORE® Linear™ System is a non-fibrous, non-fiberglass, fiber-free, fire-rated open cell acoustic foam duct liner. Consider this product when designing projects for owners who do not want exposed respirable fibers in the HVAC air stream.
HUSHCORE® BARRICADE™ SYSTEM MODEL LVQ-210-LAG
Duct radiated or breakout noise can be effectively attenuated using the HUSHCORE® Barricade™ System. For downflow rooftop unit installations, treatment of the first 15’ to 20’ of SA and RA under the unit is most critical. Model LVQ-210-LAG material is an externally applied composite sound insulation.
