An innovative partnership between Crittall Windows and Crystal Units Ltd is creating glazing that achieves the lowest available U-values combined with a host of other advantages.

A new agreement between steel window specialists Crittall and the north-London based Crystal Units involves an exclusive deal for the sale of CUIN insulating glass units that utilise a thin film inserted in the mid-point of a double-glazed unit so as to convert it to provide triple-glazed performance. CUIN’s innovative design results in a thinner and lighter construction compared to traditional triple glazing, as well as being superior in performance.

With U-values as low as 0.4 W/m²K in a double IGU, without increasing the glazing thickness or weight, this makes CUIN the eco-friendly, high performance choice over traditional glazing. And if inserted into a triple IGU a U-value of 0.2 W/m²K can be achieved. It is the most thermally efficient insulating glass unit available on the market today requiring up to 33% less glass and creating a profile that is up to 36% thinner.
