WHY AIRDOOR > Thermal coMFORT
Consistent thermal comfort at open entrances
AirDoor maintains comfortable internal conditions for customers, staff and visitors by stabilising temperatures at the entrance and reducing draughts, while keeping high‑traffic doorways open, welcoming and aligned with conditions elsewhere in the building.
How AirDoor delivers thermal comfort
Eliminates cold draughts and temperature swings
When entrances are open and used frequently, cold draughts and rapid temperature changes are common, particularly near the doorway. Traditional air curtains and overdoor heaters struggle to adapt to changing conditions, often allowing discomfort to build up in the areas people use most.
AirDoor uses a smart control strategy and variable‑speed fans to detect and respond in real time to external pressure changes, generating an active air plume across the doorway. This reduces cold draughts and smooths out the temperature fluctuations typically experienced at open, high‑traffic entrances.
Stabilises conditions at entrances
By removing the sudden bursts of cold air caused by frequent door use, AirDoor allows conditions at the entrance to remain consistent, as temperatures near the doorway no longer fluctuate every time the door opens.
This creates entrance environments that feel aligned with the rest of the building rather than noticeably colder or less comfortable. Even in busy, high‑traffic locations, conditions remain predictable throughout the day, supporting comfort, usability and uninterrupted day‑to‑day operation.
Improves comfort and wellbeing while maintaining open-door operation
Traditional approaches to entrance comfort often rely on closed doors, draught lobbies or revolving doors, which can restrict movement and disrupt how a building is used. AirDoor improves thermal comfort while allowing entrances to remain fully open, maintaining accessibility, flow and a welcoming feel.
AirDoor’s approach to entrance comfort has been recognised by the CIBSE Building Performance Awards, reflecting its ability to deliver consistent thermal comfort at high‑traffic entrances without the need to close doors or introduce physical barriers.

Additional AirDoor benefits
Performance you can measure
Weather Protection
Active protection against wind, rain and unwanted outside air, delivering consistent comfort and efficiency right across the entrance while freeing up valuable space near the doorway.
Energy Efficiency
By limiting air infiltration at the entrance and retaining treated indoor air, AirDoor reduces energy loss and helps existing heating and cooling systems operate more efficiently.
Cost Savings
With no heating or cooling element, AirDoor delivers significantly lower running costs than traditional heated systems, offering a strong return on investment and lasting long-term savings.
Indoor Air Quality
AirDoor limits the entry of dust, pollutants and insects at the entrance, supporting cleaner indoor air and healthier conditions for occupants.
Sustainability
By reducing energy consumption and carbon impact at the entrance, AirDoor helps businesses cut emissions and supports net-zero ambitions without compromising comfort or performance.

FAQs
Can’t find the answer you’re looking for?
Yes. AirDoor significantly reduces the ingress of cold external air, helping maintain stable internal conditions.
AirDoor maintains stable indoor temperatures at entrances by reducing cold draughts and sudden temperature fluctuations, creating a consistently comfortable environment for occupants. It creates an active, invisible air barrier at the entrance that keeps indoor air and the elements out.
Yes. By reducing draughts and stabilising internal temperatures, AirDoor creates a more comfortable working environment that supports staff wellbeing and productivity.
AirDoor reduces temperature variations caused by open doors, helping maintain stable internal conditions throughout the building. Heating or cooling systems within the building have less load in order to maintain consistent temperatures.
