Expert Advice and Solutions

Our Installation Process

Every energy efficiency upgrade starts with thermal imaging to identify heat loss points in your roof structure. We use advanced diagnostic equipment to measure current insulation performance and airflow issues. Our installations combine mineral wool insulation with proper eaves ventilation, ensuring your roof stays thermally efficient without moisture problems or mold growth.

Thermal Imaging Assessment

Our on-site assessment examines your attic’s current insulation depth, ventilation systems, and heat loss patterns using thermal imaging cameras. We measure existing insulation thickness against the 300mm standard, inspect all roof components for moisture damage, and photograph the attic space for documentation. Most Cork homes built before 2010 have inadequate insulation depth or ventilation blocking that reduces thermal performance. We identify these issues and calculate your potential heating cost savings based on your roof’s size and current condition. You’ll receive a detailed report showing exactly where heat escapes, recommended solutions with transparent pricing, and estimated SEAI grant eligibility. No hidden fees or pressure – just honest recommendations from Cork’s roofing specialists with 20 years of local experience.

Professional Installation Service

Professional installation combines high-performance Knauf Earthwool or mineral wool insulation with proper ventilation cards at the eaves to prevent moisture buildup. We install insulation to 300mm depth using cross-layer techniques that eliminate cold spots and thermal bridging. Every installation includes pipe and tank lagging to prevent freezing, insulated attic hatches to stop drafts, and ventilation systems that protect your roof timbers from condensation damage. Most Cork homes are completed in one day with minimal disruption. Our work meets current Building Regulations and SEAI standards, ensuring grant approval and improved BER ratings. All installations include post-completion thermal checks and detailed documentation for your records.

Quality Assurance & Verification

Multiple inspection points verify thermal performance at every installation stage. We pre-check all Knauf Earthwool or mineral wool materials before installation, confirm 300mm depth compliance across all attic areas, and test ventilation airflow to prevent moisture problems. Final thermal imaging confirms heat loss elimination and identifies any gaps requiring attention. Our fully insured team maintains detailed photographic records of before-and-after conditions for your documentation. Every project includes our 365 Emergency Assist Service for total peace of mind. Continuous training keeps our installers current with 2025 energy efficiency standards and SEAI grant requirements throughout Cork.

When Does Your Home Need Better Insulation?

Roof energy efficiency upgrades deliver immediate savings when heating bills climb unexpectedly or rooms feel cold despite constant heating. Up to 30% of home heat escapes through poorly insulated roofs in Cork’s damp climate. Our 20-year guarantee protects your investment while SEAI grants reduce costs, making upgrades affordable now.
