The Spectus flush casement windows mimic the traditional appearance of period properties, whilst offering superb energy efficiency and lower heating bills.

There’s always been a market for flush casements, but, up to now, most homeowners have opted for timber. What they’ve been waiting for is a realistic alternative: one that looks like a timber original, but which has 21st-century performance built in.

Older properties have character that needs preserving, but they’re also crying out for better insulation, better security and better weather protection. It’s taken us a while to perfect our Flush Casement. That means we’ve got authentic proportions as well as energy efficiency.

It means we’ve got all the right ancillaries, trims and finishing details. It means dummy sashes for perfect balance, deep bottom rails and the option of mechanical jointing. It also means that we’ve considered your stockholding and have ensured that these Flush Casements work alongside other elements of the Spectus range
