Quality of glass units is very important! All insulated units must have laser marks on them which is their serial number. This is the first sign that would assure you of a proper manufacturing process and it meets all standards.
This article will help you to better understand what the difference between IGU from leadership companies and IGU from self-made small businesses. We decided to do an experiment and show you windows where we replaced glass with thermopane from factory and small manufacturers. Those pictures have been taken through thermal camera.
Photo shows you one window: but right side is blue and left side is red. In any thermogram, the brighter colors(red, orange, and yellow) indicate warmer temperatures (more heat and infrared radiation emitted) while the purples and dark blue/black indicate cooler temperatures (less heat and infrared radiation emitted).
It is important here to check from where one or another company getting insulated units of glass. Supreme quality IGU will reflect heat back to the room, making it warmer and more comfortable. Warm surface of glass improve comfort and humidity of the indoor air can be controlled and adjusted properly. Proper humidity level will promote a healthier living surrounding. As well it will lower price on your utility bills.
