Door seal specialist Norseal is expanding its range of door seals with a new family of modular drop seals for hinged glass doors that combine acoustic insulation with simple installation and on-site flexibility. The Schall-Ex® family of seals includes the GSA seal, an innovative face-fix drop seal that makes retro-fitting acoustic seals on glass hinged doors possible for the first time.
Designed for both toughened (8 mm and 10 mm) and laminated safety glass (10.76 mm, 12.76 mm, and 17.52 mm), the system features five easy-to-configure variants that can be assembled quickly on-site. Thanks to a specially developed high-tech adhesive tape, there’s no need for wet bonding or mechanical fixings – just a clean, secure fix with immediate load-bearing capability.
The GSA seal is a game-changer for sealing existing glass-hinged doors on-site with minimum fuss and disruption to operations. The same innovative fixing tape works quickly to fix the seal to the face of the door, achieving sound insulation values up to 37 dB quickly and easily without having to remove the door. It’s a smart, fit-and-forget solution that is much more cost-effective than replacing doors when a retrofit solution is required to bring the door up to the required standard in situ.
Achieving sound insulation values of up to 51dB with 7 mm of floor clearance in testing, the new Schall-Ex® seals from Norseal deliver levels of noise reduction that were previously unattainable for glass doors. Ideal for offices, meeting rooms, healthcare environments, and education settings, they bring discretion, quiet, and calm to rooms where it is needed most.
To match the aesthetics of modern interiors, the seals come with a choice of cover plates – not just in classic stainless steel and silver but also in sleek black and anthracite, with smart black end stops for a clean, coordinated finish.
On-site flexibility has been built in from the start. The inner rail slides out completely for easy length adjustment or replacement of the sealing profile, and each seal in the range is the same height and fully reversible, meaning it can be installed on either right- or left-handed doors simply by turning. During fitting, the sliding actuator can be removed and adjusted without tools and then reinserted on handover.
