Background: In the construction industry, most items (locks, carpet, windows, roofing, etc.) are divided into “design grade” and “spec grade”. WebbU-factor is a number, generally between 0.2 and 1.20, that indicates the rate of heat loss (or gain) through a window. A lower U-factor demonstrates a greater resistance to heat loss and gain, i.e., better insulating value of the window. As a result, a lower number produces greater winter comfort. 4. plastic pollution ocean for kids
