Underfloor insulation in Formby

For homes and buildings in Formby, underfloor insulation is arranged survey-first: we check the property, tell you plainly what we found, and price it. 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.

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.
