With 19 Hart doors across six production facilities already operational, the contract is to replace existing roller shutters, which remain open all day, with seven Speedor Storms, one Speedor Super and one fast action roller shutter.

Peter Cairns, Hart’s area salesman, says: “The emphasis is on speed of open/close cycles to significantly reduce vermin access, mainly from pigeons, seagulls and geese attracted by the feed/agricultural nature of the production process”.

Hart is delighted to be part of a drive to improve energy efficiency by 5% by 2020, with its doors helping maintain a better working environment and temperatures within the building and preventing unauthorised access to different areas of the plant.
