The ALU-1237 model of aluminium roller shutter combines strength with aesthetics. Made from 37 mm extruded aluminium, the shutter can be upgraded to LPS1175 SR1 if required. The product can also be punched or perforated to allow for vision/ airflow if required. Ideally suited to windows and doors to domestic or commercial properties where looks are important, the shutters can be programmed to run from a variety of control methods. If insulation and sound reduction are more important, the ALU-12M37 model may be more appropriate.

Secured by Design approved, LPS1175 SR1.
