On beautiful sunny days, regardless in the summer or winter, south facing rooms in our home were just unbearable. Not wanting to change our windows, we found the solution with Sketch Nanotechnologies. From the moment applying their coating SketchNanoGard, we’ve found comfort again in our family rooms and mezzanine. All this without impacting natural light!

Thank you Sketch!

Annie L saw almost 8% savings on the energy bill when comparing 2019 vs 2020. The only improvement to their home was the application of SketchNanoGard on their windows.

She also blames Covid for the increased energy use in April and May. 😆

Keeping the heat on the right side of your windows with SketchNanoGard makes a difference; the heat outside in the summer and the heat inside during the winter, reduces your energy needs!
