As Director of the Carrefour Jeunesse-Emploi Notre-Dame-de-Grâce, I would like to express my complete satisfaction with the SketchNanoGard Thermal technology.

Our office, of about 4300 sq ft, has always suffered from a heat problem because our windows lead south with abundant sunshine. Since the application of their NANO TECHNOLOGY, our working environment has improved in an amazing way.

The benefits of SketchNanoGard Thermal were felt immediately as the infiltration of heat in the summer is reduced, thus diminishing our need for air conditioning.

Their very professional work was done outside of our service hours as to not disrupt our employees or visitors!

We are confident that this investment will improve the quality of working life for our employees and clients in a meaningful way.


Reinforcing our complete satisfaction with Sketch Nanotechnologies and the SketchNanoGard Thermal application, we convey to you the expression of our best regards.
