Window insulation designed for cold and hot climates

By Ecolo Synergy

Our Nanothermal technology has been specially designed for the Canadian climate, where extremes come and go! Whether it’s our membrane or our coating, it will reduce heat loss in winter and keep the heat out in summer!

Our window coating and membrane reduces the electrical consumption of your air conditioning and heating and improves your comfort.

Save money

  • By reducing your electricity consumption, you save on your electricity costs.
  • According to Hydro-Quebec, air conditioning and heating costs represent 54% of your consumption.
  • The insulation performance is superior to that of similar products, allowing you to considerably reduce energy consumption due to air conditioning and heating.

Improved comfort

The stabilization of the temperature inside allows you to improve your comfort, in hot or cold weather.

In addition to being transparent, our window insulation adds a polarized finish. While preventing glare, exterior colors like greens and blues are enhanced by this polarized effect.

Upgrade your existing windows

Our nanothermal insulation technology is tested for the Canadian climate and is easily installed on existing windows. Our membrane allows your windows to achieve the equivalent of Low-E certification, which means low thermal emissivity.

  • By optimizing the energy coefficient of existing windows, Ecolo Synergy’s nanothermal membrane eliminates the need to replace them as long as the frame is still in good condition.
  • The installation of our membrane is 60% less expensive than replacing your existing windows with Low-E ones. A much more affordable price for an optimal result in a sustainable way.

- Concordia University

Our beautiful glass office has a charm, but was expensive in terms of heating and air conditioning costs.  Following the insulation of our windows with Ecolo Synergy, we no longer have this problem. Our company continues to operate in comfort.

- Vincent Selection Group

I used Ecolo Synergy to insulate my windows because some rooms in my house were unusable with a constant draught. It was unpleasant and I was spending a fortune on heating in addition to condemning certain rooms. After having proceeded with the installation with the experts from Ecolo Synergy, not only can I use each of my rooms, but I no longer have to heat my garage and I save money. In addition, my children can play in the basement, even in winter!
