Masterframe has used Swisspacer warm edge spacer bars inside its sealed units for the last 10 years.

The company manufactures four styles of sash window, all of which use Swisspacer. Masterframe use Swisspacer Ultimate in both white and black, in sizes 8mm, 10mm, 14mm and 16mm.
Ramon Rabett, technical director at Masterframe, said: “Swisspacer is ideal for fulfilling the PSI values, and is a ‘hidden’ component that helps our windows achieve ‘A’ and ‘A+’ energy ratings easily and effectively.”

He continued: “We can also fix internal duplex bars to recreate an authentic Georgian look and we can bond our applied Georgian bars onto the surface of the glass using our patented Georgie clips.”
