Energy Efficient Insulation

Our comprehensive insulation systems are designed to enhance thermal performance, reduce energy consumption and improve overall building comfort, delivering long-term efficiency and sustainability benefits for residential and commercial properties alike.

Walls

Proper wall insulation is a highly effective way to improve energy efficiency and comfort. We offer external wall insulation, which wraps the building in a protective layer while allowing a range of finishes, cavity wall insulation with foam or recycled bead systems, and internal wall insulation where external changes aren’t possible. Each method is tailored to the property, ensuring optimal thermal performance while maintaining aesthetics and structural integrity.

Attics & Roofs

Insulating attics and roofs is a cost-effective way to retain heat and reduce energy costs. Options include traditional rockwool or glass fibre layers, solid boards, and Icynene spray foam, which expands to fill all gaps and provides both thermal and air sealing benefits. Properly installed, these systems improve comfort, reduce energy bills, and work with the building’s natural ventilation.

Floors

Up to 10% of heat can be lost through uninsulated floors. We provide insulation solutions for concrete slabs, suspended timber floors, or floors being replaced as part of retrofits, sometimes in combination with underfloor heating. Each approach is designed to maximise thermal efficiency while accommodating the building’s structure and long-term use.

How does insulation support Ireland’s 2030 retrofit targets for housing bodies and local authorities?

Ireland’s National Retrofit Plan requires 500,000 homes to reach a BER B2 rating by 2030. Insulation is the foundational measure in almost every retrofit pathway to B2 reducing heat loss, improving thermal comfort, and enabling heat pumps to operate efficiently. For housing bodies and local authorities managing large residential portfolios, delivering insulation at scale is one of the most critical steps in meeting retrofit programme targets and SEAI compliance requirements.

Can NetZero Group deliver insulation programmes across large social and private rental housing stock?

Yes. NetZero Group delivers external wall insulation, internal wall insulation, loft insulation, and roof insulation at scale for approved housing bodies, local authorities, and private rental landlords across Ireland. Our Envirobead and Hometherm brands are dedicated insulation companies within the NetZero Group of eight specialist businesses bringing focused expertise and high-volume delivery capability that a single-trade contractor cannot match.

Is insulation required before installing a heat pump across a retrofit programme?

In most cases, yes. Heat pumps perform most efficiently in well-insulated properties where heat loss is low. For housing bodies and local authorities retrofitting older stock, improving insulation before or alongside heat pump installation is essential to achieving the BER improvement required for SEAI grant eligibility and ensuring systems perform efficiently at scale. NetZero Group manages both scopes in-house, reducing programme complexity and ensuring compliance across the full works package.
