It is not unusual for us at Kingsbridge Joinery to receive enquiries from people looking for triple glazed sash windows. This query can be expected because people are looking for the beauty of a sliding sash window combined with optimum insulation value from modern glazing. While anything is possible really from a bespoke joinery workshop, there are two main reasons why they are not commonly used.
- Recent improvements in the u-values and performance of double glazed units have made them almost as efficient as triple glazed units
- Placing a triple glazed unit into a sash window can take from its slender appearance and make the window look bulky and commercial like.
Kingsbridge provide Certified Low U Values Windows for their customers across a comprehensive range of timber sash windows and aluminium clad sash windows.
