Introducing the world’s most airtight bar – located in Cambridgeshire


An airtight bar is a place that uses an airtight membrane to stop air leakage. This allows you to retain the warmth inside. The warm bodies enjoying their beer, the fridges, appliances, lightbulbs and the other bits and pieces that need to be on to run the pub turn into energy to keep the place warm.

By eliminating air leakage, the bar becomes an ultra-low energy consumer requiring only about 10 per cent of what a standard bar would need for energy. When you eliminate the need for heating, you cut out a pretty hefty chunk of your energy bill.

That’s right. The airtight bar does not use any heaters. It works simply with the energy captured from the people and appliances to keep the venue warm. If you’re thinking, “Umm gross”, don’t worry. Ventilation is a core strategy in the airtight building. A heat recovery ventilator allows you to keep in the warmth while also pumping out fresh air, so you’re not sitting in a stale beer and body atmosphere.

The airtight bar heats itself. Hopefully, it’s the beginning of a trend toward smarter design for less energy consumption.

Given this bar is a world first, we decided to bring in some big weights to contribute to the interior design. We also wanted to use the exposure to support a good cause.

For the bar, we worked with other world leaders in eco and innovative design. There were no other options in our mind beyond the designer and creator of the world’s most beautiful 3D textured walls, Mario Romano, and countertop designers, Corian from Los Angeles.

As of the 26th of April, these creations were officially installed, making the bar an attraction of its very own.
