How Wooden Sash Window Renovation Can Improve Energy Efficiency

Many period homes in London feature beautiful wooden sash windows, but over time these charming fixtures can become sources of unwanted draughts and energy loss. While some homeowners assume that replacement is the only option, renovating your original wooden sash windows can significantly improve your home’s energy efficiency, without compromising its character.

At Mortice & Green, we specialise in expertly restoring timber sash windows to their former glory while bringing them up to modern performance standards. Renovation isn’t just about aesthetics; it’s also about improving comfort and reducing wasteful energy use.

Draught Proofing: The Key to Insulation

A key part of our sash window renovation process involves draught proofing. This simple but highly effective upgrade seals the gaps around your sash windows without affecting their functionality. By installing discrete brush seals into the staff and parting beads during renovation, we reduce cold air infiltration and prevent heat from escaping, making your rooms warmer in winter and cooler in summer.

Better Operation, Better Energy Retention

Properly functioning sash cords and balanced sashes also play a role in energy savings. Windows that open and close smoothly create a better seal when shut, helping to maintain a consistent indoor temperature. This reduces the need to rely so heavily on central heating, cutting down your energy bills over time.

Protecting the Timber, Extending Performance

In addition to mechanical improvements, our renovation service often includes full paint removal and redecoration. This not only restores the look of the timber but also protects it from moisture and temperature extremes, ensuring your windows last longer and perform better throughout the seasons.

An Eco-Friendly Alternative to uPVC

Compared to modern uPVC replacements, high-quality wooden sash windows, when renovated and draught-proofed, can match or even outperform them in insulation while keeping the architectural integrity of your home intact.
