Sash Window Energy Efficiency Edinburgh
For expert assistance, explore professional sash window draught proofing methods for Edinburgh homes.
Sash windows are a defining feature of Edinburgh’s period properties, but many homeowners worry about their energy efficiency. The good news is that original sash windows can perform remarkably well with the right upgrades. Modern restoration techniques — including draught proofing, secondary glazing and slimline double glazing — can dramatically improve thermal performance without sacrificing the character of your historic windows.
How Draught Proofing Transforms Sash Windows
The single biggest factor in sash window heat loss is draughts. Traditional sash windows were designed with intentional gaps between the sashes and frame to allow smooth operation. Over time, timber shrinkage and wear widen these gaps, creating significant heat loss.
Professional draught proofing uses brush pile strips, silicone seals and compression gaskets fitted into precisely routed grooves around the sash and frame. This reduces air infiltration by up to 85% while maintaining smooth window operation. For Edinburgh’s Conservation Areas, this is an invisible upgrade that preserves the window’s original appearance.
Secondary Glazing for Sash Windows
Secondary glazing involves fitting a discreet additional pane of glass on the room side of the sash window. Modern magnetic secondary glazing systems are nearly invisible, with slim frames that match the window’s sightlines. Benefits include reduced heat loss, improved sound insulation and reduced condensation.
Slimline Double Glazing
For sash windows where replacement is necessary, slimline double glazing offers a modern solution. Specialist sealed units as thin as 14mm can be fitted into existing sash frames, providing U-values approaching modern double glazing standards without altering the traditional timber profile.

Frequently Asked Questions
Are sash windows inherently inefficient?
Not necessarily. With proper draught proofing, sash windows can achieve thermal performance close to modern standards.
Will secondary glazing affect the appearance of my windows?
Modern magnetic secondary glazing is designed to be discreet — slim frames that sit behind the existing window and blend into the room.
What’s the cost of sash window draught proofing in Edinburgh?
Costs vary depending on window size and condition, but draught proofing typically pays for itself within two to three heating seasons.
Can I install draught proofing on listed buildings?
Yes. Draught proofing is reversible and does not affect the external appearance, making it suitable for listed buildings and Conservation Areas.
