We can offer triple glazing on a number of products. However, it’s important to remember, that when you have a shallow unit depth (such as 24mm on a sash window), triple glazing often ends up less efficient than double glazing. We’d encourage you to talk to our sales team about your requirements. If we can understand, why you would like triple glazing, we can advise first of all whether we can offer it in your choice of product, and also whether it is the most suitable solution for your needs.
