I’m writing this letter as a testimonial for other home owners to be informed and aware, and maybe even learn from my personal experience with double pain window. I had replaced five windows in front of my house with Anlin windows through a local company three years ago. I thought, like most people, that double pane windows were all about the same. That is far far from the truth! First off, the installation was a disaster. I cannot describe the anger I felt when I saw the for workmanship that they thought they would get away with. One of the windows had condensation inside and was obviously crooked. Though the workers could not speak english and acted as if that was how the window how was supped to be, and that was how it was suppose to be installed. It was almost five most before they came back to replace the window. The worst part was how poorly the windows performed. I did not notice much difference in temperature, or noise. So when one your representatives called me and told me about “high performing windows”, I was more than skeptical. But his enthusiasm won me over! I agreed to the demo, and wow! When Miro showed up and demonstrated the Simonton windows, me and my wife were literally blown away! The windows were obviously made with thicker vinyl and glass than the Anlin windows we had installed. He put the window on the floor and stood on the glass, it didn’t break! He used the heat lamp and explained the difference between LOE3 and other standards. No heat went through. But it was the security side of the window that ultimately made us decide to replace all the windows with you. Please thank Jeff and all his crew for taking care of our home as if it was their own, going out of their way to minimize and inconvenience. The windows are amazing. We have received many unexpected compliments from our neighbors, whom two of them were our referral course for Miro and they too, decided to take advantage of Miro group purchase incentive! We have much greater difference in our cooling and heating savings and the house feels exceptionally quiet and cozy! Our savings are about 50% on cooling and heating utilities, and I have noticed because of the windows our refrigerator works less!! These windows are definitely made in the States, as Miro was explaining, compare to Milliards made in Mexico or other brands that parts would be imported from the far east. As i started doing some reading on them after all. As the saying goes.. “You Get What You Pay For”!
