Open to the eye,closed to the ear

Nothing is soundproof, and anyone who tells you otherwise is selling. What is achievable is a measurable rating. A single laminated light in a well-sealed frame typically lands around STC 35 to 39, which handles ordinary background noise. A double-glazed assembly with two independent lights, an air cavity and absorptive reveals typically reaches STC 45 to 50, which is where a normal meeting-room conversation stops being intelligible outside the room. The installed result depends on the head, base and jamb seals and on the door as much as it does on the glass.

Because sound does not need to go through the partition if it can go over it. A partition stopped at the suspended ceiling leaves the plenum as an open path between rooms, and the rating of the glass becomes largely irrelevant. Taking the head to the structural slab with a deflection channel and infilling the void above the ceiling closes that path. The deflection channel matters separately: the slab above moves, and the partition must not be asked to carry any of that movement.

Most projects install in one to five days on site. A single conference-room enclosure is usually one to two days; a full floor with several rooms runs three to five. Fabrication is typically two to three weeks after the final measure, and we schedule installation out of hours or at weekends where a floor is occupied.

Yes. Partition glass is toughened or laminated safety glazing. Toughened glass breaks into small blunt granules rather than shards; laminated glass holds together on its interlayer. Full-height glazing also gets a visual manifestation band at eye level so people can see the panel is there — that is a code requirement in glazed walkways and circulation, not a decorative choice.

Yes — swing, sliding and pivot doors, framed or frameless, in the same finish as the partition. Commercial hardware throughout: closers, locks, magnetic catches and ADA-compliant pulls and levers. On an acoustic front the door is normally the weakest element, so if the room has to perform we specify seals and a drop seal at the threshold rather than leaving an undercut.

Yes. Safety glazing, manifestation in circulation areas, fire separation where a rated line is crossed, ADA clearances at doors, and structural fixing to the slab and floor. Where a permit is required we prepare the submission and supply the system documentation the reviewer asks for.

Yes. Applied films, acid-etch effect films, gradient manifestation and switchable privacy film can all be fitted to installed glass. That is a genuine advantage of starting clear: you can see how the space is actually used before deciding which rooms need screening.

Demountable systems are designed for it. Panels, tracks and doors come down, get transported and go back up in the new space. Sizes rarely map one-to-one onto a different floor plate, so expect some panels to be re-cut or replaced — but the hardware, doors and the bulk of the glass move with you.
