Across Co. Monaghan, 60% of pre-2011 homes on the BER database still have older double glazing (U-value 2.5 to 4.0 W/m²K) or single glazing (4.0+ W/m²K), with a county median window U-value of 2.7 W/m²K. Because 23% of Monaghan homes were built between 1981 and 2000 and 43% before 1981, thousands of early aluminium and first-generation uPVC casements now have dropped friction hinges, perishing rubber gaskets and misted double-glazed units.
Near Monaghan, a normal year brings 2,182 heating degree days (the 2nd coldest of the 26 county towns). Replacing 2.7+ W/m²K windows with A-rated casements at 1.2 W/m²K (double) or 0.8 W/m²K (triple) cuts window heat loss by 55% to 70%.
