Why Replace the Glass in Your Sash Windows?

​

Original sash windows often come with single-pane glass that doesn't meet modern standards for comfort, safety, or energy efficiency. Replacing the glass — while keeping the original frames — allows you to maintain the character of your home while enjoying modern performance benefits.

Here are some of the options and reasons customers choose to upgrade:

​

• Thicker Safety Glass – More durable and harder to break; ideal for homes with children or high foot traffic

• Acoustic Glass – Reduces outside noise for a quieter, more peaceful home

• Obscure or Frosted Glass – Adds privacy without sacrificing natural light; perfect for bathrooms or street-facing windows

• Vacuum Insulated Glass (VIG) – The Rolls-Royce of glass options; delivers exceptional thermal performance in ultra-thin panes, ideal for heritage properties where traditional double glazing isn’t possible
