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!
