Extraglaze for sash windows

 

 

anim08

Simple and elegant


The Extraglaze System uses a specialist, light weight, shatter resistant acrylic material for the glazing panels. This is substantially the same material used for the lenses in spectacles and for aircraft windscreens and has exceptional optical clarity.

Our discrete panels are edged with very slender, precisely polarised magnetic strips* that automatically align themselves when removed and replaced. There are no frames as such.

The video guides, on the right hand side of this page, will help explain how the system works in more detail.

*Magnets and panel edges can be coloured to match your windows making Extraglaze almost invisible.
