Profile 22 Optima windows were specified in the development of 26 one and two bedroom apartments at Lewis House, a retirement development in Upper Norwood, London.
The window specification required a U-value of 1.4 wm2/k on all windows and Secured by Design accreditation on ground floor and easily accessible first floor windows. Acoustic glazing was also required because Lewis House is situated on a busy road so traffic noise needed to be minimised. Visually, the local authority had requested a grey exterior to give a modern appearance and provide a close match to aluminium.
Profile 22’s Optima 70mm casement windows in smooth slate grey on white with 28mm Low E sealed glass units were used for the project, with Secured by Design accredited windows fitted where required.
