Heritage Windows - 'Putty
Line'
This aluminium window system
is the perfect solution for the replacement of existing old putty glazed
steel windows. Designed to replicate the appearance and slim sightlines
of traditional putty glazed steel windows, whilst offering superior
security, weather and thermal performances. They use the latest 'Polyamide'
thermal break barrier technology, and double glazed gas filled sealed
units to achieve U values as low as 1.3.
These windows can be fitted
into original or new timber frames or direct to brick. The 45° angled
putty line design replicates old putty glazed steel windows, and will
maintain the character of your property. Finishing touches such as optional
welded corners complete the look. This system is suitable for new build
as well as replacement or refurbishment projects, for use in listed
buildings and conservation areas.
