All sashes are fitted with built-in restrictors to limit the initial opening to 80 mm providing both security and ventilation, with the use of additional restrictor positions enabling greater air-flow. The window can be produced with a ‘flying mullion’ similar to a French Casement to enable greater egress in the event of emergency, and if required for design purposes can be coupled to side or top lights from our range of Fixed and Shaped frames. The Side Swing window meets the requirements of PAS24 and Secured By Design and with the fitting of compliant hardware, the requirements of Lifetime Homes.
