Composite windows offer precise acoustic control

Top-performing sound insulation is vital for high density living, which is why Velfac aluminium/wood windows have been specified at a residential development in south London

Velfac aluminium/timber windows achieve a weighted sound reduction index of Rw32 with standard double-glazed units, rising to Rw39 by adjusting the glass thickness and glazing rebate, all without compromising the distinctive slim frame design and uniform sightlines. The windows are third-party tested and come with accurate acoustic performance data - whole unit testing not just the glass - and a range of ventilation strategies for effective noise control.

Case study: Velfac at Erith Park residential development, London

Erith Park is a 622 unit development by architects Broadway Malyan for Orbit Homes and Wates Living Space. It features four low-rise apartment buildings and 140 family homes. Triple-glazed Velfac units were specified to deliver high-performance acoustic and thermal insulation in key locations - vital for higher density living. Erith Park won the RICS 2016 London Regeneration Project of the Year award and was also shortlisted for a 2016 National Housing Award.
