Local Housing Stock
Navan property profiles
Navan has extensive suburban developments built from the 1960s to 1990s (such as Silverlawns, St. Patrick’s Terrace, and Blackcastle) with solid concrete blocks or poorly insulated cavity walls, alongside older masonry homes in the town core.
Why Wrap in Navan
Thermal & facade performance
Navan’s central Meath climate brings cold winter frosts and dampness. Wrapping the exterior with Baumit high-density EPS stops up to 45% of heat loss, eliminates condensation, and permanently improves home comfort and BER ratings.
