A fully recessed, reveal-mounted Duette® Architella® Shades can increase the R-value of a 3mm single glazed window from 0.13 to 0.78, reducing heat transfer by 83%. Independent modelling has shown that this, in turn, can reduce an average home’s heating costs by up to 43.3%.**
* The R-values are the combined measurement of 3mm (one-eighth inch) CI glass (R=0.127) plus the window covering and are reported in metric SI units. Thermal properties are determined by a certified third-party laboratory utilising accepted ASTM, NFRC and WES standards and procedures. Measurements may vary based on window type and method of installation. ** Savings are based on the installation of fully-recessed, reveal-mounted Duette Architella Shade with 20mm Panache Blockout fabric in an average home in Sydney, compared with the House Energy Rating standard of Holland Blinds from AccuRate, in that home. These calculations have been modelled by an independent third party. Savings will vary based on the window type and installation.
