Seasonal inflatable insulation panels are an innovative approach to improving a building’s thermal performance while maintaining flexibility throughout the year. Unlike fixed insulation, these panels can be deployed during colder months to retain heat and deflated or removed during warmer months to allow natural cooling. This adaptability can significantly impact a property’s Energy Performance Certificate (EPC) rating — but only if the EPC modelling process accounts for their seasonal nature.
How Seasonal Inflatable Insulation Affects EPC Modelling
EPC assessors use standardised software to model a building’s energy performance, but this software assumes a static thermal envelope. Seasonal insulation challenges this assumption.
Winter months: Inflated panels reduce heat loss through walls and roofs, potentially improving the EPC score.
Summer months: Removing or deflating panels can prevent overheating, reducing cooling loads and improving comfort.
Because these performance changes aren’t constant, EPC modelling must factor in time-dependent insulation values and realistic occupancy patterns.
Challenges for EPC Assessors
Dynamic U-values: The insulating properties of the building envelope change seasonally.
Software limitations: Standard EPC tools may not directly account for temporary insulation, requiring assessor notes and additional justification.
Occupant behaviour: The actual benefit depends on correct seasonal use by occupants.

Residential EPC Considerations
If you’re a homeowner installing seasonal inflatable insulation, you may wonder whether your EPC will reflect the improvement. Our Residential EPC service ensures these features are assessed accurately, taking into account both winter efficiency gains and summer cooling benefits.
Same-Day EPC for Projects with Inflatable Insulation
Need certification quickly? Our Same Day Energy Performance Certificate (EPC) option allows property owners to get results fast, even for buildings with non-standard insulation technologies.
Cost Implications
Seasonal inflatable insulation panels can be more affordable to install than permanent retrofits. For a breakdown of costs and how they compare to EPC gains, see our Pricing Plan.
