The energy Star.gov website has a section called energy savings at home. Solar window screens made by Josh Hobbs.com are energy Star compliant. Meaning our solar screens, have passed the testing and meet the qualifications as a Energy Star approved device. Federal tax credits do apply for solar screens made by Josh Hobbs.com. You can also read on the Josh Hobbs.com website under the questions and answers page more about the federal tax credits for this calendar year. One of the things that the energy Star website, the energy savings at home section of the energy Star website, talk about, is sealing and insulating with energy Star devices. Focusing effort and energy on ceiling and insulating is fine and is by all means necessary, but it is not paramount to shading your Windows with solar screens. I know from first-hand experience, what reward and gains are achieved by over insulating an attic. Not very much. I have done a great deal of experimenting myself. I have fooled around with extensive amounts of attic insulation, whereby I have used indoor/outdoor thermometers in the attic and haningin one foot from the ceiling. I have also implemented huge attic fans, and have not seen a great deal of improvement. The number one source of heat gain, and it is a big one, is heat from your Windows. That’s if you live in the hot Texas. Solar window screens will shade those Windows, whereby the heat will not get into the house. All of these people that argue that insulating an Attic being a paramount function is just flat wrong, I know from first-hand experience what it is like to have a home that has zero insulation in the attic and only having a 5/8″ piece of sheetrock to separate the room from the attic. I have personally experienced this. I have remodeled many homes in my life. And I have done many of these during the heat of the summer. One time in particular I remember it being 105° outside having no insulation up in the attic and before I did the installation in the attic of which I put 14 inches of, I used an indoor/outdoor thermometer to get a temperature reading of inside the attic and a foot down from the sheet rock. The temperature reading did not change all that much when I added the insulation. Hardly at all. I don’t remember how much, but I do remember being shocked. Now I am not dumb, it wasn’t that I expected the temperature reading to change immediately after I added the insulation. I compared the readings from day one with the following days with insulation. Meaning, I made note of what the temperature readings were upstairs in the attic and a foot down from the sheet rock without the insulation. Then I watched those same readings over period of days after we put the insulation up into the attic. The difference was trivial. Now, you take that same indoor outdoor thermometer and you do the same thing on a window and when you say that window, you will see a huge temperature difference reading. Now, I can’t say the same for cool weather. If it is cold in your attic, that cool air will find its way through that sheet rock, hence the need for insulation. Now, I am not advocating that you do not use insulation in your attic by any means. I am just saying that the my testing and personal experience, did not yield a huge difference in temperature variances once I put the insulation in the attic.
