What We Solve in Greenwich
World Heritage Site Sensitivity
Greenwich's World Heritage status means external alterations are heavily restricted. Our fully internal secondary glazing avoids any impact on the protected townscape.
Wind Exposure on Blackheath
Homes bordering the open heath face strong wind-driven rain. Our high-performance perimeter seals eliminate draughts and cold bridging in these exposed positions.
Original Crown Glass Retention
Many Greenwich windows retain rare crown and cylinder glass. Our secondary units protect these irreplaceable panes while improving thermal and acoustic performance.

Greenwich Homes, Streets and Noise: What We See on Survey
The oldest houses we work on in Greenwich are around Crooms Hill, Royal Hill and Gloucester Circus, where early Georgian terraces still have original sashes and, in some cases, historic crown or cylinder glass with its characteristic ripple. That glass cannot be replaced like for like, so secondary glazing is often the only acceptable way to improve comfort without risking it. Further east, the Ashburnham Triangle and the streets around Maze Hill are mostly Victorian, with taller sashes and bay windows, and Blackheath has large villas and terraces around the heath and in the Paragon.
Greenwich's noise is less obvious than central London's but just as persistent where it occurs. The A206 Trafalgar Road and Romney Road carry heavy traffic and tourist coaches past the Maritime Greenwich site, and homes near the A102 approach to the Blackwall Tunnel experience near-constant traffic. Southeastern trains run through Greenwich and Maze Hill stations, the DLR serves Cutty Sark and Greenwich, and parts of the borough see aircraft heading to and from London City Airport. For these frontages we combine acoustic laminate with a wide air gap.
Exposure is the other local issue. Houses facing Blackheath take wind and rain straight off the open heath, which finds every gap in an old sash. Here the perimeter seal is doing most of the work, and owners usually notice the end of the draughts before anything else.
