How Timber Homes Achieve Strong BER Ratings in Ireland

24 September 2025 By Krzysztof

Every home sold or rented in Ireland needs a Building Energy Rating (BER) — and with energy prices where they are, buyers pay attention to it. Timber construction has a structural head start in this race.

Why Timber Performs Well

  • Warm walls by nature: Wood conducts far less heat than concrete or steel, so the structure itself contributes insulation rather than draining it.
  • Deep insulation zones: Timber frame walls hold thick layers of mineral wool without making the building bulky. See our construction system for the full build-up.
  • Airtight precision: Factory-made panels fit tighter than site-built blockwork, cutting the draughts that ruin real-world performance.

What It Means in Euro

The difference between a poor and a strong BER can be hundreds of euro in heating every year — and a visible advantage the day you sell. Combined with a heat pump, well-insulated timber homes reach the ratings modern buyers expect.
