For businesses with frequently open doors or high levels of footfall, maintaining warmth can be an expensive game. Without the right measures, valuable energy escapes, cold drafts creep in, and temperatures quickly drop; meaning more energy is needed to raise the level back to where it should be.

Biddle Air Curtains, however, have products designed to prevent this. Creating a barrier of air, preventing heat loss across an open threshold and helping buildings stay warm, welcoming, and energy efficient.

A Warm Welcome Without the Drafts

For 175 years, humans have known that hot air naturally migrates to cold. So, in the winter months, any time a door is opened into the street, all the heat energy will rush out – putting more strain on internal heating systems to raise temperatures.

By creating an invisible barrier of air, Biddle Air Curtains separate indoor and outdoor climates without restricting access, keeping warmth inside and blocking unwanted cold drafts.

Energy Efficiency Benefits

Air Curtains are not merely focused on comfort – they also deliver measurable energy savings:

  • Reduced heat loss – Prevents warm air escaping through entrances, reducing wasted energy
  • Lower heating demand – By maintaining stable internal conditions, building heating systems don’t need to overcompensate
  • Sustainability in action – Limiting energy waste lowers operating costs and helps reduce carbon emissions

With heating accounting for a major share of winter energy costs, these savings quickly add up.

A Better Environment for People

Cold drafts at entrances will create uncomfortable environments and impact overall wellbeing. By eliminating sudden temperature fluctuations, air curtains maintain even conditions and better air quality. They also help limit the entry of outdoor pollutants, dust, and fumes, further improving indoor environments.

Designed to Fit Every Environment

Biddle Air Systems manufacture a wide array of comfort air curtains to match any aesthetic, with bespoke colour options available in a number of models.

And for applications where discretion is a key factor, recessed models are available to keep the unit out of sight.

 

When winter sets in, entrances become a heat sink for conditioned environments, with the temperature difference causing heat energy to migrate outside. Air curtains provide a simple but highly effective solution – maintaining warm, stable, and welcoming environments whilst also preventing spikes in energy costs.

We may not wish to admit it, but winter is coming. And at Biddle, our air curtains are engineered to deliver the perfect balance of comfort and efficiency.
