Secondary Glazing Sash Windows for Heritage and Modern Properties

Secondary glazing sash windows are the perfect, thermally efficient, solution for owners of heritage homes. This is a vertical sliding secondary glazing that fits on the inside of a vertical sliding sash window to help improve its heat performance.

Listed properties often find that they are unable to replace their sash windows with modern double glazing. This is because it can affect the traditional outer appearance of these buildings. Secondary glazing sash windows, on the other hand, sit discreetly on the inside. They function in the same way as double glazing but without impacting the façade.

In addition, our modern secondary glazing sash windows offer a number of great benefits befitting a modern home. As a result, they aren’t just perfect for heritage properties but also modern buildings that want that vintage look which only sash windows provide.

Easy Usability with Secondary Glazing Sash Windows

Secondary glazing sash windows are designed especially for vertically sliding windows where regular hinged panels aren’t suitable. In fact, these are specifically modelled along the same lines. There are two secondary sashes, one above the other, securely retained in their outer frame.

The vertically sliding secondary glazing is supported by robust spring balances. What these do is provide ease in opening and closing.

In addition, the spiral balance system supports the weight of the secondary sashes. As a result, these secondary glazing sash windows are quite suitable for larger sash windows as well.

Another excellent feature vertical sliding secondary glazing offers you is the tilt-in facility. This feature allows each secondary sash to be independently released from the outer frame. It can then be pivoted inwards through almost 180°. As a result, you will find it as easy to clean the outside of the glass as it is to clean the inside.

Additionally, the sight lines of secondary glazing sash windows are designed to match traditional sash windows. The sashes are also easily moved up and down with the weights supported by the balance system.
