A forceful blow can break PVC shutters, but in the case of aluminium, it will have greater resistance to impact as well as being more resistant to fire.

This explains why the metal aluminium is used in security shutters to close shops and other types of establishment.

Thermal and acoustic insulation

Both types of roller shutters are equipped with polyurethane filled slats which ensures a high degree of thermal insulation and acoustic insulation. However, if we consider the ability to insulate temperature, PVC blinds perform better, as plastic transmits less heat than aluminium blinds.

Although this disadvantage of aluminium roller shutters is reduced when the windows have thermal break. This means that the window profile and glass ensure insulation from the heat and cold outside.

Both are easy to clean with a high degree of safety (just open the drawer and wipe with a damp cloth while rolling and unrolling to clean the outside.

But it should be borne in mind that, if we choose to extruded aluminiumThe more resistant, more durable roller shutter can cost up to 200 €/m2. The price of installation and the type of blind can also influence the final price.
