The Green answer to the night door nightmare?

摘要

Seymour Manufacturing claims to have come up with a solution to the much hated coldroom night door. The company's Green Door is said to be the most energy saving cold room door with the longest life and minimum servicing requirement available on the market. More significantly, it's installed without a night door. According to Seymour Manufacturing, the benefits of this are manifold: there is no night door to keep constantly closed; no high capital cost associated with a night door; no night door maintenance expenditure; and no alarms being disabled by staff with intriguing deployment of chewing gum or the like.
