Underfloor insulation in Banbury

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 Banbury we follow the England rules on building notices and self-certification, and confirm the route on your quote.

Underfloor insulation for Banbury properties

Banbury sits in Oxfordshire, around 22 miles north of Oxford. We work across the OX16 district, including nearby Bicester, Witney and Oxford.

Small measures like this are often among the cheapest per pound saved, and they suit Banbury homes of every age. In Banbury homes this is often done on the same visit as a cavity fill, which saves a second trip.

As for paperwork, if cavity wall insulation follows in Banbury, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
