Outdoor Roller Shutter System: Outdoor roller shutter systems, usually made of aluminum and PVC, provide protection against burglary attempts for your home or business premises. In addition, the level of security can be further increased with automatic locking mechanisms. Thermal insulation: Roller shutters help reduce heat loss through your windows or doors, keeping warm air in in winter and preventing overheating in summer. Automation Options: Outdoor roller shutter systems are available with both manual motors and remote control options.
