Installed into the reveals, this unobtrusive
system has minimal impact on the primary
windows, whilst maintaining full functionality.
All secondary glazing sight lines will be
matched up with your existing mullions to
ensure that your windows retain their period
features without being hindered by secondary
glazing – a priority when preserving the
character of your historic property whilst
improving the thermal efficiency.
Our slim, lightweight framework can be
powder-coated to any RAL, BS number or wood
effect finish to complement your existing decor
and provide you with a perfect finish, which is
virtually invisible, outside and in.
This style of secondary glazing can be made to
fit the exact nature of your primary windows,
and can be engineered to accommodate out
of true cills and heads and even splayed
reveals. Our horizontal sliding panes are easily
removable to allow cleaning and maintenance
of primary windows.
Our horizontal sliding units can be
manufactured from two, three or more panes
to suit the primary window.
