317 Whitechapel Road forms part of a significant mixed-use development in the heart of East London’s vibrant Whitechapel district. The six-storey building, managed by Places for London, comprises 14 contemporary apartments above ground-floor retail space. TRC’s window replacement programme was crucial in upgrading the residential units, which range from one to three bedrooms, enhancing both their thermal and acoustic performance.

The property’s location, directly opposite Whitechapel Underground station and the new Elizabeth Line, made the specification of high-performance acoustic glazing particularly important for resident comfort. The building’s prominent position on Whitechapel Road, a major arterial route, demanded windows that would not only perform technically but also complement the area’s architectural character.

The project

TRC Contracts delivered a £120K window replacement scheme at 317 Whitechapel Road, London, a prominent mixed-use development opposite Whitechapel station. Working with H A Marks Ltd, TRC manufactured and installed over 60 Easy Clean sash windows, specifically engineered for this residential project where access considerations were paramount.

The bespoke units feature a practical 50-degree tilt and slide mechanism for internal cleaning, while meeting rigorous performance requirements including enhanced acoustic protection (Rw=36 dB), PAS24 security standards, and superior thermal efficiency (U-value: 1.4 W/m²K). All windows were manufactured using FSC certified hardwood timber, ensuring sustainability credentials.

Technical Excellence: Easy Clean Sash Windows

TRC’s Easy Clean sash windows combine traditional aesthetics with innovative functionality, making them ideal for contemporary restoration projects. Engineered specifically for buildings where external access is challenging, these sophisticated units feature an intelligent tilt-and-slide mechanism that allows the sash to tilt inward at a 50-degree angle, enabling safe and convenient cleaning from inside the property.

For 317 Whitechapel Road, each window was manufactured to meet exacting performance criteria:

Superior acoustic protection with double-glazed units achieving Rw=36 dB
Enhanced security compliance to PAS24 standards
Exceptional thermal efficiency with a whole-window U-value of 1.4 W/m²K
Sustainable FSC-certified hardwood timber construction

This solution delivers the perfect balance of traditional appearance, modern functionality, and technical performance, making it particularly suitable for residential developments in urban locations where maintenance accessibility and occupant comfort are key considerations.
