Electric Roller Garage Doors Hemel Hempstead

Homeowners in Hemel Hempstead can take advantage of the latest automation systems from trusted manufacturers such as Somfy and NRG, bringing effortless convenience and modern performance to their garages. With an extensive range of colours and textured woodgrain finishes, each door can be tailored to match the character and design of your property.

Every Trojon roller garage door installed by SDM Doors comes complete with a fully enclosed aluminium shutterbox — included as standard, not as an upgrade — for a neat appearance and extra protection. Built-in safety features include a smart safety edge that automatically reverses the door if anything is detected in its path, and a manual override to allow access even during a power cut. For total reassurance, the advanced Selve locking system provides outstanding strength and resistance against forced entry.

Our doors are crafted from 77mm insulated aluminium laths, supported by robust guide rails, end plates, and a matching shutterbox, ensuring smooth, quiet operation and excellent thermal insulation year after year.

All Trojon roller doors meet the latest European safety regulations and are designed with longevity and user safety at their core. Each one includes a mechanical safety brake, which engages instantly in the unlikely event of motor failure — working much like a seatbelt to stop the curtain from dropping suddenly.
