…demands. Quadruple glazing may be necessary to achieve desired levels of energy efficiency in Arctic regions, or to allow higher glazing ratios in curtain walling without increasing winter heat loss. Its low thermal transmittance can also eliminate the need for modulated external sun shading, as solar gain can…
