What is the impact of supermarket fridge doors on shopper behaviour?  A 2017 study found that fridge doors caused 22% fewer shopper interactions with products; a 29% reduction in chiller aisle shoppers going on to make a purchase; and a 13% fall in grab-and-go sales.

That was in 2017 - what’s changed since then? In this blog, we revisit these findings in the context of present-day shopper behaviour, to judge how doors might be influencing sales in 2026.

Are fridge doors about to become legally mandatory across Europe?

The answer is No. Fridge doors are not a legal requirement in the EU.

Though many retailers think so. Refurbishment plans are being rewritten. Open cabinets are being phased out. All based on speculation about what regulation might do next. The issue is they're acting on assumptions, and not the facts.

We often hear from retailers who feel forced to choose between the energy efficiency of glass doors and the trading benefits of open fronts.

The good news? You no longer have to choose.

This article explores how Invisidoor™ stabilises the air curtain to deliver the efficiency you need without adding a physical barrier, and how its aerodynamic design solves the core performance issues that have limited open-fronted refrigeration for decades.

In our latest e-book, we reveal why modern open cabinets with aerodynamic technology can outperform traditional doored fridges. From CFD modelling and real-world trials to results from Sainsbury’s, ASDA, Tesco and M&S, this guide breaks down the true performance of each approach - and what it means for retailers today.

Energy savings from fridge doors rarely match store results. See what testing misses and how retailers should rethink their refrigeration strategy.
