Airport Terminals: High-Performance Noise & Thermal Insulation

A technical guide to specifying non-combustible building rolls and acoustic slabs to isolate landing jet noise and optimize massive HVAC spaces.

Airport Terminals: High-Performance Noise & Thermal Insulation

Aviation passenger terminals present complex thermal and acoustic challenges. With high-velocity jet exhausts nearby, structural roofs and curtain walls require extreme sound transmission loss profiles, combined with strict Class-A1 life safety fire limits.

1. Sound Isolation (STC 50+ Specs)

To shield passengers from jet noise frequencies, terminal roofing assemblies specify dual-layer stone wool slabs. Cured to high densities (96 kg/m3 or higher), these layers deliver Noise Reduction Coefficients (NRC) up to 0.90, absorbing sound energy rather than reflecting it into the concourse.

2. Solar Gain & HVAC Optimization

Airport terminals feature large glass envelopes and expansive metal roof decks. Direct solar thermal transmission through uninsulated steel decks can trigger massive cooling loads. Installing faced building rolls with high-performance ALG foil wraps forms a continuous heat block, reducing chiller demand by up to 20%.
