I was shopping for new windows to replace my original ones. With COMFORTEC I have exactly what I wanted for a reasonable price. I replaced all 8 windows and a sliding door before winter came. The product and service were outstanding and we feel the difference in terms of thermo- and sound insulation. The installation had been done within a single day. It is done professionally satisfying such a picky person like me: decent amount of internal and external insulation, nice finish around the frames and no rubbish left after the work done. The windows are made of non-recycled material and look very nice from the inside and outside. The insulation level is really impressive: during the winter day, when the furnace is switched off, the temperature goes down only 1 degree! We saved significantly during this winter. What's more, the window itself made with double glass, each one with different thickness. We do not hear a sound of landing planes anymore! The bottom line is, Comfortec was the most competitive among other quotes. You can get a very good product, enjoy for long years to come and not go bankrupt.All Reviews
