Parallel windows are suitable for both domestic and commercial properties. They are suitable for either window replacement in existing buildings, or for installation in to new build properties. Parallel windows are also ideal for insertion into both low and high rise buildings.

They are best suited for commercial buildings such as apartments, offices, hospitals and block of flats which require effective and natural ventilation, whilst maintaining security and safety.

Including enhanced security makes this window an even more attractive option when combining it with its environmental benefits.
