The Problem: A Cold, Condensation-Prone Utility Room
The utility room at the Greenhams’ home was uncomfortably cold and draughty. The cause? A large, single-glazed window letting in cold air — and heavy condensation from their tumble dryer making things worse. Replacing the window with a full UPVC double-glazed unit wasn’t an option. What they needed was a solution that would retain brightness, allow ventilation — and drastically improve warmth and comfort.
Our Solution: Made-to-Measure Secondary Glazing
We recommended and supplied a bespoke solution: the Omega SmartSlider 3‑Panel Secondary Glazing Unit — custom-made to the exact window size. Glazed with clear 4 mm super-tough plate polycarbonate sheets, this secondary glazing allows the utility room to stay light, while sealing out cold draughts.
We also provided clear, detailed instructions and measuring guidance to ensure a perfect fit and easy installation.
The Outcome: Warmth Restored — Without Losing Light or Ventilation
Since fitting the SmartSlider secondary glazing:
-
The utility room is now noticeably much warmer and more comfortable.
-
Despite the retrofit, the room remains bright and airy, with natural light preserved.
-
The unit retains access for ventilation, essential for the tumble dryer.
In short: a cold, inefficient utility room has been transformed into a warm, practical, and hygienic space — all without the expense or disruption of replacing the original glazing.
Why This Case Study Matters for Homeowners
-
It demonstrates how secondary glazing can drastically improve comfort and energy efficiency, especially in rooms prone to cold and condensation.
-
It shows that a cost-effective, simpler retrofit can deliver many of the benefits of full double glazing — with less disruption and lower cost.
-
It highlights the importance of custom measurement and professional guidance to ensure proper fit and performance.
Recommendations & Considerations
If you’re dealing with a cold, draughty room — especially rooms with existing single-glazed windows — consider secondary glazing as an easy, effective retrofit solution. For best results:
-
Ensure accurate measurements to get a snug, draught-proof fit
-
Choose durable glazing material (e.g. tough plate polycarbonate) for longevity and safety
-
Retain ventilation access if the room includes appliances like a tumble dryer or washing machine
