Question: There are such values, called R-values. They define the resistance to heat loss per unit time, temperature difference and area (i.e., higher is better). These are English units, hour-degreeF-ft^2/BTU. An R-value of 20 means that 100 sq. ft. of wall separating a 20 deg F temperature difference for 8 hours passes 800 BTU of heat. Typical recommended R-values (ref. 1) for use in residences are 4 to 60, depending on climate and location in the house. For walls the range is 11 to 28. In the ref. 2 web site you can find R ratings for various insulation materials, in R-value per inch of insulation thickness, and thicknesses required for various recommended R-values.

Answer: What's the rate of heat loss through a domestic well-insulated wall per sqm when the heat differential is 15C?

Question: It's called denial...

Answer: How does a person live his whole life with the notion of impending death

Question: Most onboard video for PC desktop motherboards are far short of performance for even a PCI-only card. For the Intel 845 chipset, having a dedicated PCI video card can definitely improve your performance, especially for 3D games.
