Moisture management is often overlooked in retrofit. When insulation and airtightness improve, moisture movement changes.
Without good design and ventilation, condensation, mould, and damage can occur.
Deep retrofits must balance heat, airtightness, and moisture.
#KORERetrofit #HealthyHomes
As homes become more airtight, ventilation must be well designed. MHRV brings in fresh air, removes stale air, and recovers heat, improving air quality and cutting heat loss.
Ventilation isn’t optional in deep retrofit, it’s essential for performance.
#KORERetrofit #MHRV #IndoorAirQuality
Airtightness is often misunderstood. It’s not about sealing a home fully, but controlling airflow.
Poor airtightness causes heat loss, drafts, higher energy use, and condensation risks.
Improving it lets ventilation work properly.

Energy prices have changed how many homeowners think about their homes.
Deep retrofit offers long-term benefits
• Reduced heating demand
• Lower energy bills
• Improved comfort
• Increased property value
It’s an investment in future-proofing homes.

A Fabric First retrofit strategy prioritises:
• High-performance insulation
• Airtightness improvements
• Thermal bridge mitigation
• Controlled ventilation

Heat pumps come in a variety of outputs depending on the heating needs of the home.
For this project, we installed a 13kW heat pump, and for context, here’s our project manager Seamus (5'8 tall) standing beside it.

Why Airtightness Matters 🏠
Airtightness controls unwanted air leakage, keeping heat in while ensuring fresh air is delivered properly.
It’s improved through sealing gaps, airtight membranes, upgraded windows & doors, and mechanical ventilation

Did you know?
Most Irish homes were built before today’s insulation standards. That means heat loss through the building fabric is often the main reason for high energy bills - not the boiler. Fix the fabric, and everything else performs better.

Being smart with your heating can make a real difference to your energy use.
Simple steps like using timers, lowering the thermostat slightly and ensuring good insulation can help keep your home warm without overspending.
Small changes = smarter heating.
#EnergySavingWeek25 #KOREretrofit
Stop heat escaping by upgrading your insulation and reducing draughts, this can make a noticeable difference to warmth and efficiency in your home.
A warmer home starts with better protection from heat loss.
