Acoustic Triple Glazed Unit — Roof & Overhead Acoustic Glazing
Rooflights and skylights are among the worst noise offenders in any building — rain drumming, aircraft noise, and wind buffeting are amplified by the horizontal orientation and direct exposure. Our 44dB Acoustic Triple Glazed Unit, configured for overhead installation, addresses all three noise sources with laminated acoustic glass that also meets overhead safety requirements.
Standard rooflights with basic double glazing can transmit rain noise at 60-70dB — loud enough to make conversation difficult. Our acoustic overhead unit reduces rain drumming by up to 15dB compared to standard glazing, and cuts aircraft noise transmission in half. The laminated inner pane (required by BS EN 12600 for overhead positions) doubles as the acoustic interlayer.
How 44dB Acoustic Glazing Works
Standard sealed units use identical glass thicknesses on all panes — which creates resonance at specific frequencies, allowing noise through. Our acoustic units use asymmetric glass configurations (typically 6mm outer, 4mm middle, 6.4mm acoustic laminated inner) that break up resonance patterns across the full frequency spectrum.
The acoustic PVB interlayer in the laminated pane is specifically formulated to dampen sound vibration — it's softer and more viscoelastic than standard PVB, absorbing energy rather than transmitting it. Combined with argon gas fill and Low-E coating for thermal performance, this unit doesn't sacrifice energy efficiency for noise reduction.
