"Hi I'm James with JNC Home Repair and today I am going to show you how to reduce indoor heat gain from your windows. Basically there is a couple of different things you can reduce the heat coming in through your windows. You can actually replace the window with a double pane, double hung window pane glass. That will definitely help with some of the heat transfer coming through the window. If you don't really want to get that extensive you could go with something just as simple as actually installing a solar screen around the window. That will actually reduce about 50% of the heat coming in through the window and it will actually block it before it even hits the window the screen will. Sometimes you can even just put your hand up to the window and you can actually feel the heat coming through the glass and that is actually going to hurt your energy efficiency inside the house. Another couple of things you are going to do is you can also make sure that where the frame meets the drywall all the way around the window you can make sure that it is caulked real well. You can see right here that this window is caulked real well. There is no cracks, there is no leaks. You can tell that there is no kind of air flow actually coming in between the frame and the wall and the other thing that you can do to reduce heat gain is also make sure to look where the window is actually meeting the aluminum frame and what that is is just some basic silicone or weather stripping that is actually in there that is sealing the glass to the frame and if you look in there and you see any kind of cracks or you see that it is peeling back or anything, you may want to just rub some silicone down in there and kind of help seal this because that is where your air flow is coming in or out. If it is cool inside and it is hot outside then naturally the hot air is going to want to try to come in and you just want to make sure that this is all sealed up well and that you don't have any kind of leaks around the window and by doing that you will reduce some of your heat gain coming in the windows."
