400 Caledonian Road consists of a Victorian townhouse together with its original stable block. Sustainable property developers Igloo, purchased the property back in 2012. They have recently restored this property, and with the help of Selectaglaze have managed to secure a Gold award for Best Sustainable Development from Whathouse Awards 2015.  Selectaglaze was chosen as the preferred secondary glazing specialist due to previous projects that have been successfully completed with the developer over a number of years. Six slimline units from the Series 20 range were installed to the interior side of the original primary sash windows. Each unit was bespoke in order to ensure a perfect fit to each opening and each unit  was glazed with 6.8mm Stadip glass, which is an acoustic laminage. When a minimum gap of 100mm was created between the primary and secondary unit in order to achieve a sound reduction in excess of 50dB within each treated room. The Selectaglaze Series 20 range are discreet slimline units ideal for heritage properties. They blend seamlessly with the primary windows and provide acoustic and thermal benefits.
