Underfloor insulation in Portadown

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. We cover Portadown and the wider BT62 postcode district, with the survey, result and fixed price all in writing.

Underfloor insulation for Portadown properties

Portadown sits in County Armagh, around 3 miles south-west of Craigavon. We work across the BT62 district, including nearby Craigavon, Lurgan and Armagh.

Small measures like this are often among the cheapest per pound saved, and they suit Portadown homes of every age. We check ventilation as carefully as insulation in Portadown homes, because both matter for keeping a house dry.

For regulations, if cavity wall insulation follows in Portadown, inserting cavity wall insulation needs a building control application to the council before work starts.

Keeping the void ventilated

Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.

What is included in Portadown

  • Insulation between joists
  • Draught sealing at skirtings
