Do I really need Triple Glazing?

Triple glazing is often marketed as the ultimate solution for energy efficiency in skylights and windows, offering impressive thermal performance metrics. On paper, Triple Glazed skylights can achieve remarkable U-values as low as 0.6 W/m²K, suggesting exceptional insulation capabilities that surpass standard double glazing options.

However, the practical benefits of triple glazing for residential applications remain a subject of ongoing debate among building professionals. While triple glazing does provide additional thermal insulation, the real-world impact on home comfort and energy consumption may be less significant than the specifications suggest, particularly in moderate climate regions like the UK.

The cost-benefit analysis is an important consideration for homeowners. Triple-glazed skylights typically come with a higher initial purchase price and installation cost compared to quality double-glazed alternatives. In many cases, the incremental energy savings realised through triple glazing may take many years to offset this premium, if at all.

For most residential applications, high-quality double-glazed skylights with Low-E coatings and Argon filling (like those offered in Skyseal's standard range) provide an optimal balance of performance, cost-effectiveness, and environmental benefit.
