Should you spend money on double glazing or a holiday?
Roger asks as he delves into the practical and financial considerations of replacing single-glazed windows with double-glazing.
Roger discusses the challenges of maintaining single-glazed sash windows, such as drafts, rattling, and the frequent need for painting and sanding.
While double glazing offers improved draft-proofing and comfort, Roger points out potential downsides, including condensation issues and the risk of sealed units misting up, leading to costly repairs.

◾ Summary
🌧️ Single vs. Double Glazing: The video discusses the maintenance challenges of single-glazed sash windows, their aesthetic impact, and the pros and cons of replacing them with double-glazed windows.
💷 Cost Analysis: Highlights government data showing potential savings of around £100 annually on heating bills with double-glazing, but questions if the investment (~£10,000) is financially worthwhile over the long term.
🔧 Comfort Trade-offs: While double glazing improves draft-proofing and comfort, it can lead to issues like condensation and misting, requiring additional maintenance.
📊 Alternative Investments: Investing the same money in financial products like an ISA could yield similar returns over time without the upfront cost of window replacement.
🛠️ Practical Tips: Simple measures like using heavy curtains and optimizing natural sunlight can significantly reduce heat loss, offering an effective, low-cost alternative to double glazing.
◾ Compared to other insulation measures:
Loft insulation can save up to 30% of heat loss, making it a more effective solution for overall energy efficiency.
Cavity wall insulation and floor insulation also provide significant benefits, often contributing to a more considerable reduction in energy consumption compared to window replacement alone.
◾ Insights Based on Numbers
£100/year is the estimated savings with double-glazing, which may rise with increasing fuel prices.
Based on current savings, a £10,000 investment for double glazing may take over 10 years to recoup.
Windows account for 18% of heat loss, but double glazing only reduces it to approximately 10%.
