Tocqueville's impression of American attitudes toward the relation of government and religion was formed on his tour of the United States in the early 1830s during the high tide of evangelicalism:
The room begins to heat up as the summer sun beats down on the glass. There are a few things you can do about it in a relatively short time. 1  An awning or outdoor window shade will stop most of the sun's heat before it comes to your window. 2  Install shades or shutters on the offending windows for more comfort when needed.
The NFRC places a label on all Energy Star windows with various measures of energy efficiency, including: 1  U-factor: How well a product prevents heat from escaping. 2  Solar Heat Gain Coefficient (SHGC): How much heat from the sun is blocked. 3  Visible Transmittance (VT): How much light comes in through the window.
