On this page

Garage door in Ireland: sectional €1,500–€3,500, roller €1,800–€4,000, up-and-over €800–€1,800. If the garage is habitable space (used as a home office, a playroom, or a bedroom), the door is counted in the BER and must be insulated. U-value ≤1.5 W/m²K for Part L 2022. Sectional is the most common for new builds — opens vertically, good ceiling insulation, multiple panel finishes. Up-and-over is the cheapest — swings out, less weather-tight. Roller is best for tight spaces — rolls up into a box, no ceiling track. Most Irish self-builds with attached garages use sectional; detached garages use up-and-over for cost.
