Types of Window Glazing for Sash Windows

When it comes to improving your home’s energy efficiency and comfort, installing double glazed sash windows is often an easy decision. However, with so many types of window glazing available, choosing the right option for your home can feel a little overwhelming.

At Sash Window Specialists, we are dedicated to offering the highest quality products that blend authentic period style with the very latest in energy-efficient technologies. Our expertly crafted glazing solutions help keep your home warmer, quieter, and more secure, while preserving the charm of your original timber windows.

Why Choose Glazing for Windows?

All of our double glazed units deliver exceptional thermal performance, with a U-Value of 1.6 or lower. A low U-Value means your windows will significantly reduce heat loss, keeping warmth inside your property and helping to lower your energy bills.

Every window design is rigorously tested and certified to meet these performance standards, so you can feel confident that you are making a sound investment in your home’s comfort and efficiency.

Understanding the Different Types of Window Glazing

Choosing between the different types of window glazing may seem confusing at first, but our experienced team is here to guide you through the process. We take the time to explain the benefits of each option in clear terms, helping you select the glazing that best meets your needs, whether your priority is insulation, soundproofing, security, or maintaining period authenticity. Whether you’re thinking about traditional timber casement windows, or period timber sash windows we’ve got you covered.

By the time you place your order, you will have a complete understanding of the exact glazing specification chosen for your windows and doors.
