20 cm), the space above the purlins if a standing seam roof is used, and the option to offset the liner below the bottom purlin flange as much as needed to achieve the desired insulation depth and effective thermal resistance without compressing the insulation.
Their models allow a designer or installer to determine the effective thermal resistance for any purlin spacing.
purlin spacings reduce the effective thermal resistance by approximately 10% and 25%, respectively, compared to 60 in.
