Secondary Glazing for Apartments

Apartments in urban areas are exposed to a wide range of noise and thermal challenges. Road traffic, pedestrians, neighbouring properties, bars and restaurants — urban living means noise is a constant presence. Combined with the often poor thermal performance of older apartment buildings, the need for effective window improvement is acute.

Why Secondary Glazing Suits Apartments

Secondary glazing is particularly well-suited to apartments for several practical reasons:

• No external alterations — installed entirely internally, so nothing is visible from outside the building
• Lease-friendly — satisfies the requirements of most leasehold agreements that prohibit external alterations
• No structural work — no changes to building structure or fabric
• Reversible — can be completely removed when vacating the property
• Effective noise reduction — up to 80% with acoustic specification

Leasehold Considerations

Before installing secondary glazing in a leasehold flat, check your lease. Most leases allow internal alterations that do not affect the building's external appearance or structure. If your lease is unclear, obtain written permission from the freeholder or managing agent. We can provide documentation describing the non-intrusive nature of the installation to support this process.

Urban Noise Reduction

For apartments in noisy urban environments, we recommend reveal-fixed installation with 150–200mm air cavity and 6.8mm acoustic laminate glass. This delivers up to 80% perceived noise reduction — transforming noisy urban rooms into genuinely quiet spaces.

Mansion Block Sash Windows

Victorian and Edwardian mansion blocks typically retain original timber sash windows. Our BVS/TBVS secondary glazing is the perfect solution — designed for sash windows, virtually invisible from inside or outside, and delivering outstanding noise and thermal performance.
