Recommended Product Lines
TSC High-Density HVAC Board
High-density rigid board for HVAC duct lining and equipment lagging. A1 fire per EN 13501-1, sound absorption per EN 13162 acoustic appendix. Hydrophobic treatment minimizes moisture absorption in conditioned-air systems.
TSCL Industrial HVAC Slab
Industrial format slab for repeat-volume HVAC projects. Same density as TSC with cost-efficient slab format for plenum walls and large equipment housings.
Standards & Certifications (Verified)
All certificates listed below are physically on file with downloadable PDFs. None are pending or in-progress.
HVAC Use Cases
Duct Lining
Internal duct lining reduces breakout noise from supply and return air ducts. Fire performance A1 per EN 13501-1. Local mechanical engineer verifies thickness against project NC rating target based on the SGS/Intertek acoustic test reports we provide.
Equipment Lagging
Air handling unit, chiller, and pump lagging for thermal and acoustic treatment. Hydrophobic treatment resists condensation in conditioned-air environments.
Plenum Walls
Mechanical room and plenum wall fill — fire-rated A1 partition with sound transmission control. Engineer specifies STC rating based on test reports for your assembly.
Mechanical Room Acoustic
Mechanical room acoustic absorption to control reverberant noise. Density per acoustic engineer's NRC target — ask for SGS/Intertek detailed test reports for your frequency band.
