Underfloor insulation
Insulation beneath suspended timber floors to stop draughts and keep warmth in, with access and ventilation considered from the start.

Service Details
At Northstar Insulation Co., we install underfloor insulation for homeowners across the region. If your property has a basement, cellar, or crawl space, we can install Rockwool insulation - stapled and netted beneath your floor to stop draughts and retain heat. We also install Kingspan rigid board insulation beneath floors prior to underfloor heating being laid.
It's an often-overlooked area that can make a real difference to draught control, heat retention, and overall comfort - especially in older properties.
We'll assess your property and recommend the right product and approach for your floor type and situation.
Our underfloor insulation service includes:
Property assessment - we check your floor type, void depth, and access before recommending the right solution
Preparation - we clear the void or subfloor area and prepare for installation
Installation - Rockwool is stapled and netted between joists, or Kingspan board is laid to the required depth ahead of underfloor heating
Finishing - access points are closed and the area is left clean and tidy
Aftercare advice - we walk you through what's been done and answer any questions
Every job is carried out by our trained installers to a consistent, high standard.
