How It Works
Effective protection in summer and winter, in the south and in the north
Where does the sun's heat go?
On a summer day, the heat that comes through the glass doesn't leave. It warms the air near the window, the floor and the furniture, then builds up in the room.

- The room heats up much less, and heat builds up more slowly
- Natural light still comes in
In winter, keep more heat inside
On a cold night, some of the heat from your heating escapes through the windows, and the cold glass fogs up with condensation. The membrane sends more of it back into the room.

Colors that last longer
UV rays fade fabrics, woodwork and products on display. The membrane blocks 99% of them at the glass, without taking light away from the room.

Frequently Asked Questions
The product
What is the warranty?
10 years for our nanothermal window insulation.
Does the insulation protect my furniture and fabrics?
Yes. Our product blocks up to 99% of UV rays, which protects your furniture and fabrics from fading.
Is it toxic?
No. Our products meet environmental standards, are certified and approved. Safe for everyone.
Does it change the appearance of my windows?
Slightly. Our membrane allows visible light through while blocking heat and UV. It may give windows a slight bluish tint, but the effect remains subtle.
What is the return on investment period?
Generally between 1 and 4 years: about 1 year where energy is expensive, 4 years at most where it is affordable (in Montreal, for example, about CA$0.10 per kWh), thanks to savings on cooling and heating. Savings vary depending on your windows' initial condition and existing insulation.
Installation and maintenance
Is the installation done inside or outside?
Except in certain exceptional cases, installation is done inside your premises.
Do I need to leave the premises during application?
No, the application is safe and you can stay on site. However, the installation is not completely silent and requires clear access to windows. If this may affect your work or concentration, we can adapt to your schedule or work during low-occupancy periods.
Can it be installed in winter?
Yes, we can install the product in winter. You'll just need to allow for longer drying time and the premises must be heated, but the product's effectiveness is not affected.
Are residential homes qualified?
Yes. The majority of our clients are commercial, but we also do residential installations with the same level of quality.
How do I clean the windows after installation?
Use a soft microfiber cloth with products free of ammonia, abrasives, alcohol, or vinegar. These products could damage the membrane. For a stubborn stain, see the difficult cases in our care guide.
