Our Insulation Installation Process

Our Cork-based team starts with thermal imaging to identify heat loss areas in your roof. We install high-performance mineral wool or spray foam insulation to Irish Building Regulations standards, then conduct final inspections to verify our 20-year guarantee specifications. Every installation includes a post-work BER assessment and grant documentation.

Initial Evaluation

We begin each Cork roof insulation project with a comprehensive thermal assessment using advanced heat-loss detection tools. Our technicians examine your roof structure, ventilation, and existing insulation to identify problem areas costing you money. We measure heat loss at critical points like eaves, joints, and penetrations where most energy escapes. Moisture issues, air leaks, and structural concerns are documented before we design your custom insulation solution. You receive a detailed report with thermal imaging results and a transparent quote showing costs minus any SEAI grants you qualify for.

Professional Roof Insulation Service Cork

Keystone’s certified installers use mineral wool insulation and spray foam systems proven to deliver 30-40% heating bill reductions in Cork homes. We prepare your roof space by sealing air leaks and addressing moisture problems before installation begins. Our team installs insulation to 300mm depth (or greater) meeting current Irish Building Standards, paying special attention to eaves, ridges, and junctions where heat loss typically occurs. Every installation undergoes quality checks at three stages: preparation, installation, and final inspection. We complete all SEAI grant paperwork and BER certification as part of our standard service.

Quality Assurance

Every Keystone roof insulation project meets strict Irish Building Regulations and SEAI specifications for Cork properties. We use calibrated thermal imaging post-installation to verify insulation performance against heat loss targets. Our quality guarantee includes proper ventilation maintenance, moisture barrier integrity, and complete coverage with no gaps or compressed areas. All work is backed by our 10-year home security promise and 365 emergency assist service. As fully registered and insured contractors serving Cork for over 20 years, we maintain the highest standards in thermal performance and installation safety.
