ISO 10077-1:2006 PDF Download

ISO 10077-1:2006 is a standard that provides methods for calculating the thermal transmittance of windows, doors, and shutters. The standard covers different types of glazing, such as glass or plastic, and considers factors such as single or multiple glazing, low emissivity coatings, and the use of air or other gases in the spaces between glazing layers. It also includes the calculation of thermal transmittance for opaque panels within the window or door.

The standard allows for various types of frames, including wood, plastic, metallic with or without thermal barriers, and metallic frames with pinpoint metallic connections or combinations of materials. It also includes the consideration of the additional thermal resistance introduced by closed shutters, depending on their air permeability.

Thermal transmittance calculations can be applied to roof windows and projecting windows, provided that the thermal transmittance of their frame sections is determined by measurement or numerical calculation. Default values for glazing, frames, and shutters are provided in the standard.

It is important to note that the standard excludes the calculation of thermal bridge effects at the rebate or joint between the window or door frame and the rest of the building envelope. It also does not include the effects of solar radiation, heat transfer caused by air leakage, calculation of condensation, ventilation of air spaces in double and coupled windows, and the surrounding parts of an oriel window. Additionally, the standard does not apply to curtain walls, structural glazing, or industrial, commercial, and garage doors.
