How Draught Proofing Can Transform Your Sash Windows

Sash windows offer timeless charm and elegance. However, old sash windows often struggle with draughts, leading to heat loss, higher energy bills, and reduced home comfort. Fortunately, draught-proofing provides a simple yet effective way to enhance their efficiency while preserving their traditional aesthetic.

Reducing Heat Loss

Over time, small gaps can develop, allowing warm air to escape and cold air to seep in. Draught-proofing seals these gaps, improving insulation and maintaining a more stable indoor temperature.

Lowering Energy Bills

By preventing heat from escaping, your home stays warmer with less reliance on central heating. This improved efficiency translates into lower energy consumption and reduced heating costs—helping both your wallet and the environment. ”Despite the general fall in prices since early 2023, typical bills under the January to March 2025 energy price cap will still be just over 40% higher than in winter 2021/22” – commonslibrary.parliament.uk/

Enhancing Home Comfort

Draughts can make rooms feel chilly in winter and inconsistent in temperature year-round. By eliminating unwanted airflow, draught-proofing helps create a more comfortable and consistent living environment.

Preserving Aesthetic Appeal

Many homeowners worry that modifications will alter the period charm of their sash windows. Fortunately, draught-proofing is a discreet solution that enhances performance without compromising the original design.

Minimising Noise and Dust Ingress

Beyond insulation benefits, maintaining your windows to reduce droughts can also reduce external noise and prevent dust and debris from entering your home. This results in a quieter, cleaner, and healthier indoor space.

Common Causes of Draughty Sash Windows

Over time, sash windows can develop various issues that contribute to draughts and energy inefficiency, including:

Gaps and Cracks: Wooden frames may shrink or warp, creating spaces that allow air infiltration.
Loose or Cracked Putty: The putty securing the glass panes can deteriorate, leading to air leaks.
Worn Sash Cords and Unbalanced Weights: These can cause improper window alignment, resulting in gaps.
Single Glazing: Older sash windows often feature single-pane glass, which offers minimal insulation compared to modern double glazing.

DIY Draught-Proofing Solutions

For homeowners looking to address draught issues themselves, several methods can be employed:

Sealing Gaps: Applying flexible fillers or sealants to gaps in the window frame can prevent air leakage.
Replacing Putty: Removing loose or cracked putty and resealing with fresh putty ensures a tighter seal around the glass panes.
Installing Draught Excluder Strips: Flexible adhesive strips can be applied to the window edges to reduce draughts while allowing the window to remain operable.

While these DIY methods can provide temporary relief, they may not offer a long-term solution and could affect the window’s functionality. For a more permanent and effective fix, professional draught-proofing is recommended.
