We had 3 sets of french doors removed and 3 sets of stacker doors installed. 2 of the sets installed were 3.4m x 2.8m. They are amazing! They have made a vast difference keeping our house warmer in winter and cooler in summer and reduced our energy consumption by about 20%.

The customer service was exemplary and nothing was too much trouble. Not only would I have no hesitation recommending Smart Glaze, I think you would be doing yourself a disservice if you went with anyone else.
