An invisible barrier that minimises heat loss
Heat losses from commercial and industrial buildings result in discomfort for occupants and increased heating costs. Frequently opened doors – such as those in reception areas, retail or leisure premises, or delivery bays – compound the problem.
As the following table shows, heat losses through open doors can be dramatic – and expensive. Based on a fuel cost equivalent of 1.5p/kWh, a single 6x6m doorway open 24 hours a day for 215 days from October to April would waste energy worth £16,700.
