DT Services Ltd manufactured and installed a new 3 phase insulated roller shutter for Dragonfly Sign and Display Limited, located in Hessle just outside of Hull.
Roller shutters help businesses to save money, firstly with the insulated door to improve heat retention and also by providing an opening only when the entrance is in use, reducing the amount of time that heat is able to escape.
The shutter is fully compliant with BS EN 13241:2003+A2:2016, which sets out the performance requirements for domestic and commercial doors, gates and barriers.
