Since 1974 Starglaze have been helping customers install state-of-the-art sliding sash windows, and today we bring to the table the level of experience you can expect from a company that’s been in business for over four decades.

Our windows are designed to the specifications outlined by the impressive Spectus profile. Widely regarded as one of the best uPVC sash windows there is, this stunning product line can offer the aesthetic appearance of timber without any of the structural weaknesses that were known to affect the material over time in decades long past.

The Spectus line of sliding sash windows is one of the most impressive products of its kind. Regularly touted as one of the best choices for any home improvement project, this incredible design offers compatibility, versatility and all the other features you’d expect from such a product line including thermal efficiency and maximum security.

You can easily customise these sash windows with a choice of many colours and woodgrain finishes depending on your preference. You can also specify trickle or glazed-in vents, and the design can be made up to 1600mm wide and 3000mm high. The overall outerframe is 128mm, and the cills are 150mm and 210mm.

Spectus sash windows also take the natural beauty of this design and build upon it with hardware modifications and a series of notable features. You can add in your choice of Georgian bars, sash horns, weather bars and much more, and the authentic ovolo shape of the frame, bead, cill and sash will make your window stand out.

Choosing Starglaze as your installer of choice will benefit you in the short-term as you receive a premium product at an affordable price. However, this will then continue to be a cost-effective installation as the years go by thanks to the A-rated Window Energy Rating this product line earns thanks to the anti-draught mechanics and 24mm sealed unit.
