HOW TO MAINTAIN YOUR HERITAGE SASH WINDOWS

Heritage sash windows are a quintessential feature of many historic buildings across the UK,offering charm and character that modern windows simply cannot replicate. Maintaining thesewindows is not just about preserving the appearance of a building; it's about conserving a pieceof history. With advancements in technology, such as Cocoon's InvisiTherm® secondary glazingsystem, it's now easier than ever to maintain these windows' functionality and efficiency withoutcompromising their historical integrity. This blog delves into practical steps for maintainingheritage sash windows, inspired by the expertise of Historic Environment Scotland.

Regular Maintenance

The key to preserving sash windows lies in regular, careful maintenance. Simple actions like routine cleaning of glass and timber surfaces can prevent decay and extend the windows' lifespan. It's also crucial to inspect the windows regularly for signs of wear or damage, particularly in the operating mechanisms, and to address any issues promptly to prevent further deterioration.

Painting and Weatherproofing

Protecting the woodwork with appropriate paint and treatments is essential for weatherproofing and can prevent rot and decay. It's generally recommended to repaint exterior surfaces every five years, depending on exposure to the elements. Using microporous paint allows the timber to breathe, reducing the risk of moisture build-up and subsequent damage.

Upgrades for Efficiency

One of the challenges of maintaining heritage sash windows is improving their energy efficiency without altering their appearance. Traditional sash windows are known for being draughty, but with the advent of secondary glazing solutions like InvisiTherm®, it's possible to enhance thermal performance and sound insulation. InvisiTherm® is designed to be discreet, preserving the windows' original aesthetic while significantly reducing heat loss and noise infiltration.

Repairs and Restoration

Despite their robust design, sash windows may require repairs due to age or environmental factors. Techniques such as splicing in new timber for decayed sections, replacing damaged cords or chains, and restoring stuck windows can all be undertaken to restore functionality. It's often more cost-effective and sustainable to repair existing windows than to replace them, especially considering the superior quality of the original materials.

Incorporating Modern Solutions

While traditional craftsmanship is essential for maintaining the character of sash windows, modern innovations like InvisiTherm® can play a crucial role in ensuring their viability as functional elements of a building. By choosing solutions designed with heritage in mind, it's possible to enjoy the best of both worlds: preserving historical charm while meeting contemporary standards of comfort and energy efficiency.
