Underfloor insulation in Downpatrick

Underfloor insulation fits mineral wool or rigid boards between the joists of a suspended timber floor, supported on netting or battens, so cold air from the ventilated void below stops chilling the room. In Downpatrick we follow the Northern Ireland rules on building control applications, and confirm the route on your quote.
