Glass in building — Determination of steady-state U values (thermal transmittance) of multiple glazing — Guarded hot plate method ISO 10291:1994

Publication date:   Sep 15, 1994

Scope

Specifies a measuring method used to determine the coefficient of thermal transmittance, the U-value, of multiple glazing with flat and parallel surfaces, including cast and figured rolled glass. Applies to multiple glazing with outer panes which are not transparent to far-infrared radiation, which is the case for normal window glass. Internal elements may be far-infrared transparent.
