Is triple glazing worth it in Dumbarton?

For historic castle town properties in Dumbarton, triple glazing offers significant benefits over double glazing — up to 50% less heat loss through windows, virtually zero condensation, and noticeably warmer rooms. It's particularly worthwhile for north-facing and exposed properties.

What's the difference between double and triple glazing?

Triple glazing has three panes of glass with two insulating gas-filled cavities, versus two panes and one cavity in double glazing. This gives U-values of 0.6–0.8 vs 1.2–1.4, meaning 40–50% less heat escapes through the window.

How long does triple glazing last?

Quality triple glazing installed by Heatscape in Dumbarton comes with a 20-year guarantee and typically lasts 30+ years. The sealed units maintain their insulating properties throughout, protecting your historic castle town property for decades.
