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.
Base System
HUSHCORE® BASE™ SYSTEM MODEL NIC
Type NIC Non Isolation Curbs are for use with internally isolated small tonnage rooftop units. For packaged RTUs that include condenser sections, style HIR-2 or HIC-2 Isolation Rails/Curbs are recommended.
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.
Deck System
HUSHCORE® DECK™ SYSTEM MODEL DS-38
The model DS-38 Deck™ System is a multi-layer configuration which is an excellent alternative to traditional gypsum board treatments for equipment curbs. The DS-38 System outperforms traditional treatments by up to 2 STC points. The DS-38 System provides improved lower octave band transmission loss to the DS-32 System without a steep increase in price.
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® DECK™ SYSTEM MODEL DS-53
The HUSHCORE® model DS-53 Deck™ System uses our same composite acoustic panels as our DS-52 System. However, due to recent material shortages we are unable to offer our DS-52 System. The DS-53 model is a temporary equivalent offering to our DS-52 System. The DS-53 provides a high level of transmission loss for equipment curbs installed overtop noise sensitive spaces. This assembly provides for a quick and easy installation without sacrificing acoustic performance. For noise critical projects, you may need to consider our DS-57 System.
Linear System
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.
Barricade System
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.
