Introducing AirDoor
AirDoor is an award-winning, innovative alternative to traditional overdoor heaters.
It creates an invisible, active air barrier that adapts in real-time to changing weather conditions – without heating or cooling.
Reducing air infiltration, improving thermal comfort, and lowering energy demand at open entrances.
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.
Thermal Comfort
By maintaining consistent indoor temperatures and reducing cold draughts at the entrance, AirDoor creates a more comfortable environment for customers, staff and visitors.
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.
Our Products
Built for every entrance
Our flagship, high-performance entrance solution
AirDoor integrates seamlessly around most commercial openings, creating an invisible, active air barrier that keeps entrances open and welcoming while reducing infiltration and energy loss.
Our solution for entrances with overhead space constraints
AirDoor Lite creates the same active air barrier as AirDoor, but in a pillar design, ideal for buildings where architectural constraints limit the use of an overhead crossbeam.
Our solution for temperature-controlled spaces
AirDoor Curve is specifically designed for adjoining indoor spaces that need different temperatures, where its unique twisted pillars keep hot and cold zones separate.

FAQs
Can’t find the answer you’re looking for?
AirDoor is a commercial entrance technology that uses smart sensors, a smart control strategy and variable speed fans to create an active, invisible air barrier which limits rain, wind and dust getting in and keeps conditioned, indoor air inside.
No. While both create an air barrier, AirDoor is engineered to deliver higher performance in real environments. While air curtains use a continuous flow of heated air (usually from above), AirDoor uses sensors and a smart control strategy to control variable speed fans which ramp up and down as weather conditions alter, creating an air barrier which keeps indoor air in, and the elements out. It provides stronger, more consistent separation at entrances, reducing heat loss, draughts and air infiltration more effectively than conventional air curtains.
No. AirDoor does not use heating or cooling elements. It relies on a high-performance air barrier to retain the building’s conditioned air, maintaining consistent temperatures using the existing HVAC system rather than generating additional heat or cooling.
AirDoor reduces heat loss, improves thermal comfort and limits air infiltration at open entrances. It creates stable indoor conditions, lowers energy consumption and enhances occupant experience, all while maintaining open and accessible doorways.
Yes. AirDoor significantly reduces heat loss through open entrances, lowering heating demand and cutting energy consumption. This results in measurable cost savings, particularly in high-traffic buildings with frequently used or permanently open doors.
Traditional air curtains and overdoor heaters rely on a constant stream of air from above (often heated) to counteract cold air entering, which can be noisy and inefficient. AirDoor takes a different approach, preventing air infiltration in the first place. Its intelligent control strategy responds to changing conditions, adjusting fan performance only when needed, delivering quieter operation, lower energy use and significantly reduced running costs.
