Products composed of more than one type need each type's U-value to be accounted for.[2] Glass makeup description can refer to a separate table.[3] Product width, height and area are frame sizes taken from shop drawings, and may be in IP or SI units.[4] U-values are normally reported to two decimals. Some manufacturers prefer to report them with three or more, which is permissible for this table.[5] U x A is calculated as: Quantity x area x U-value. [6] Divide Total UxA by Total Area. If supplier's calculations are based on IP units, the overall average U-value should be calculated with IP units.[7] If overall average was calculated with IP units, it needs to be converted to SI units.Print area07/09/2019justinh
