SSH ISO 15099:2003

Thermal performance of windows, doors and shading devices — Detailed calculations

Scope

ISO 15099:2003 specifies detailed calculation procedures for determining the thermal and optical transmission properties (e.g., thermal transmittance, total solar energy transmittance) of window and door systems based on the most up-to-date algorithms and methods, and the relevant solar and thermal properties of all components.
Products covered by ISO 15099:2003 include windows and doors incorporating:
single and multiple glazed fenestration products with or without solar reflective, low-emissivity coatings and suspended plastic films;glazing systems with pane spacing of any width containing gases or mixtures of gases;metallic or non-metallic spacers;frames of any material and design;fenestration products tilted at any angle;shading devices;projecting products.
