Knauf Insulation launches 3D U-value calculator

The tool enables architects to instantly generate more accurate U-values for steel frame rainscreen façade specifications. It is designed to help architects more closely reflect as-built performance in their designs and avoid costly over-specification.

“Ordinarily, architects might have to wait up to two days to get this information. Now they can use the tool at any time and get an instant result. And they can revise their designs as much as necessary to reach their target U-value,” said Bradley Hirst, technical services manager at Knauf Insulation.

Standard U-value calculations for rainscreen façades assume a default bracket configuration, applying a blanket correction factor for the build-up, which can lead to specifying needlessly thick insulation or result in a gap between designed and actual performance, Knauf noted. The 3D U-value calculator works from the architect’s actual design to provide a more accurate result.

The calculator helps architects ensure compliance by delivering a design more likely to perform as intended in the real world. It also creates a detailed report that helps to meet regulations and protect the specification by showing the potential impact of inappropriate substitutions.
