Lowest U-values available

A partnership between Crittall Windows and Crystal Units is said to be 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 design is said to result 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 is said to make CUIN the eco-friendly choice over traditional glazing. And if inserted into a triple IGU a U-value of 0.2 W/m2K can reportedly be achieved.
