Underfloor insulation in County Tyrone

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. Our County Tyrone coverage includes Omagh, Dungannon, Cookstown and the towns around them.

Underfloor insulation across County Tyrone

We cover 4 towns in County Tyrone: Omagh, Dungannon, Cookstown and Strabane.

Where a County Tyrone home also has empty cavity walls, we can survey those at the same time. We check ventilation as carefully as insulation in County Tyrone homes, because both matter for keeping a house dry.

Building control in Northern Ireland

In Northern Ireland, inserting insulation into an existing cavity wall needs a building control application to your council before the work. We make sure the application route is agreed and confirmed in writing before any drilling starts.

Funding in Northern Ireland

  • The Affordable Warmth Scheme, run with the NI Housing Executive, helps owner-occupiers and private tenants with a total gross household income under £23,000; cavity wall insulation is a priority measure where suitable.
  • The NI Sustainable Energy Programme funds energy efficiency schemes through participating providers.
  • ECO4 does not apply in Northern Ireland.

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

  • Floor void inspection
  • Insulation between joists
  • Draught sealing at skirtings
  • Boards relaid
