Notes:

Footnote 1

The concrete layer considered in the numerical modeling is 200 mm thick with a density of 2 400 kg/m³ and a conductivity of 1.4 W/m∙K for k1 and 2.9 W/m∙K for k2. As per the ASHRAE Handbook, the average conductivity for concrete with a density of 2 400 kg/m³ is 2.2 W/m∙K.

Footnote 2

Excludes room- and weather-side air films.

Footnote 3

This value takes into account the interior and exterior air film conductance data from the ASHRAE Handbook of 8.29 W/m²∙K (corresponding resistance is 1/8.29) and 34.00 W/m²∙K (corresponding resistance is 1/34.00), respectively. This is the design thermal resistance value to be used for Code compliance.

Footnote 4

The furred air space assembly consists of the LEM within a sealed air space with furring. Room- and weather-side air films are excluded.

Return to footnote 4 referrer

Footnote 5

The contribution of the furred air space assembly to the thermal resistance of the complete wall is calculated as the difference between the thermal resistance of the tested complete wall and the base wall.
