In Co. Meath, 50% of all households live in a detached house (CSO Census 2022) and 24% of the county's housing stock was built between 1981 and 2000 — the two decades when 1.5-storey dormer bungalows became the dominant house type across Irish rural sites and town outskirts. On SEAI's BER register for pre-2011 homes in Meath, 56% still have first-generation double glazing (U-value 2.5 to 4.0 W/m²K) and a median window U-value of 2.7 W/m²K.
Near Navan, a typical year averages 2,048 heating degree days (the 10th coldest of the 26 county towns). Because upper dormer windows project straight out of the pitched roof slope, replacing draughty 1990s dormer frames with 0.8 W/m²K triple-glazed casements and packing the side cheeks with rigid PIR insulation stops upstairs heat escaping into the roof space.
