ventilation upgrades

Proper ventilation is crucial for a healthy indoor environment. We install modern ventilation systems that reduce moisture, improve air quality, and work seamlessly with insulation upgrades.

Ventilation upgrades are a critical part of any energy retrofit. As insulation improves and homes become warmer and more airtight, controlled ventilation is essential to maintain good indoor air quality and prevent condensation, mould growth, and moisture-related damage.

Ventilation is not optional under SEAI-funded retrofit works—it must be assessed and upgraded where required to ensure the long-term performance of the building and the health of occupants.

Why Ventilation Upgrades Matter

  • Protects indoor air quality after insulation upgrades

  • Reduces condensation and mould risk

  • Maintains a healthy living environment

  • Ensures compliance with SEAI and SR 54 requirements

  • Supports long-term performance of insulation systems

Insulating a home without addressing ventilation can lead to moisture problems. Our approach ensures insulation and ventilation work together as a complete system.

Ventilation as Part of SEAI Retrofit Works

Under the SEAI Domestic Technical Standards & Specifications and SR 54 Code of Practice, ventilation must be:

  • assessed as part of every retrofit project
  • upgraded where existing provision is insufficient
  • suitable for the level of airtightness achieved

Ventilation upgrades may be required following:

  • External Wall Insulation
  • Internal Wall Insulation
  • Attic / Roof Insulation
  • Airtightness improvements

Our Ventilation Upgrade Approach

We deliver practical, proportionate ventilation solutions, tailored to each property.
Depending on the assessment, this may include:

  • Background (permanent) ventilation
    • wall vents or window vents sized to requirements
  • Mechanical extract ventilation
    • kitchens, bathrooms, utility areas
  • Upgrade or replacement of existing fans
    • to meet airflow and control requirements
  • Reinstatement and protection of vents
    • where affected by insulation works

All solutions are selected to meet SEAI guidance while minimising visual impact and disruption.

Installed in Line with SEAI & SR 54 Requirements

All ventilation works are carried out in accordance with:

  • SEAI Domestic Technical Standards & Specifications
  • SR 54 – Code of Practice for Energy Efficient Retrofit
  • relevant Irish Building Regulations (Part F – Ventilation)

We ensure:

  • correct airflow rates
  • correct positioning and detailing
  • compatibility with insulation systems
  • readiness for SEAI inspection and verification

Integrated with Your Insulation Works

Ventilation upgrades are planned together with insulation, not as an afterthought. This integrated approach ensures:

  • no blocked or compromised vents
  • correct detailing through insulated walls
  • balanced performance between airtightness and fresh air supply

This is essential for long-term compliance and occupant comfort.

A Critical Step in a Compliant Retrofit

Ventilation upgrades protect both the home and the people living in it. When delivered as part of a properly designed retrofit, they ensure your energy upgrades are safe, compliant, and sustainable.

As a contractor experienced in SEAI grant-funded and compliance-led retrofit works, we treat ventilation as a core element of quality not an add-on.

FREQUENTLY ASKED QUESTIONS

Homeowners can access SEAI Home Energy Grants to help cover the cost of insulation upgrades. The exact grant amount depends on the measure and property type. For example, external wall insulation grants can be up to €8,000 for a detached home, €6,000 for a semi-detached, €3,500 for a mid-terrace, and €3,000 for an apartment. Other insulation grants (attic, cavity, internal wall) have their own values based on property type.

Yes. To be eligible for SEAI grant funding, all energy upgrade works including insulation must be carried out by an SEAI-registered contractor. This ensures the installation meets SEAI technical standards and is inspection ready. After works are completed, you’ll also need to submit a post-works BER assessment and signed documentation to SEAI to draw down the grant.

This depends on the measure and property size:

  • Attic or cavity insulation: typically, 1-2 days
  • Internal wall insulation: several days, depending on scope
  • External wall insulation: usually 2-4 weeks
