TestimonialsHeritage 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.
