I need a glass guru. After Hurrican Charley I paid extra to have the west facing windows in my home replaced with double-paned glass. I thought it would solve the solar oven problem in my diningroom. Well - it didn't. The windows are quite warm to touch when the sun is on that side of the house. I called the window installer and he came out to check them. I wasn't home when he was there. He opened the windown and felt the inside pane, then he felt the outside pane. There was a noticeable difference in temperature - the outside being much hotter. He used that as evidence that the windows were indeed insulating. I'm not so sure I agree. I mean - the inside of my home is air-conditioned - it would seem natural that the interior of the glass would be cooler - no? It does not mean that the glass is not transferring heat into my home. How do I check on this to make sure I'm being given the straight dope? Anyone know?
