Secondary Glazing Specialists in the City of London
Secondary Glazing for the City's Barbican Estate, Livery Halls & Historic Residences
The Square Mile is better known for offices than homes, but it contains some of London's most distinctive residential settings — the Grade II listed Barbican and Golden Lane estates, the Georgian and Victorian houses of Smithfield and the Temple, and a growing stock of converted commercial buildings. Constant construction, traffic and early-morning deliveries make acoustic performance the priority here, and the City's heritage controls make internal secondary glazing the natural solution.

What We Solve in City of London
Listed Brutalist Window Systems
The Barbican's original frames are protected by its Grade II listing. Our reversible, internal secondary units are designed around the estate's specific window modules and leave the originals untouched.
Round-the-Clock Construction Noise
The City rarely stops building. Our acoustic laminate glass targets the impact and plant noise from neighbouring sites that thin single glazing transmits directly.
Thermal Loss in Concrete Frames
Large single-glazed openings set in concrete lose heat quickly. Secondary glazing creates the insulating air gap these buildings were never designed with.
