Secondary vs Triple Glazing in
Bishop's Stortford

Secondary glazing typically provides superior noise reduction (40-45dB) compared to triple glazing (32-37dB) due to the larger air gap between the original window and secondary pane.

Triple glazing in heritage properties depends on planning restrictions. Secondary glazing is often preferred as it preserves original windows while still providing excellent performance.

Secondary glazing costs £200-400 per window compared to £450-900 for triple glazing. Secondary glazing offers better value for heritage properties with planning restrictions.

Triple glazing provides better thermal performance (U-value 0.8-1.0) compared to secondary glazing (1.8-2.5). However, secondary glazing still achieves 60-70% of triple glazing's energy savings.

While possible, triple glazing is usually preferred for modern homes as it provides maximum energy efficiency and a cleaner aesthetic without the need to preserve existing windows.

Triple glazing typically adds more value (£8,000-12,000) compared to secondary glazing (£3,000-6,000). However, for heritage properties, sympathetic secondary glazing may be more valuable than inappropriate modern windows.
