  • Isolation. Filled with polyurethane foam, they are a perfect acoustic barrier, in addition to serving as a sound barrier. blinds to insulate against heat and from the cold outside.

Disadvantages of aluminium roller shutters

  • Aluminium, being a metal, functions as a energy carrier and produces greater heat dissipation.
  • It has a high dilatation and loses its watertightness.
  • It is a material more expensive than PVC and thermal insulation can be improved with thermal breaks.

PVC external blinds

The PVC is a plastic material and is one of the most widely used materials for blinds due to the advantages it offers.


PVC blinds are made of plastic and are commonly found in homes and offices. As with aluminium blinds, they are composed of slats injected with polyurethane to increase the strength of the blinds. acoustic and thermal insulation.

They are more light than the aluminium versions and this makes them usable up to a certain size and easy to raise or lower (if not motorised). However, the permitted width is lower for PVC blinds than for aluminium blinds, a fact that must be taken into account if the window opening is wide.

These blinds can be fitted with a traditional, mini or compact drawer and we can find a variety of colours, although in smaller quantities than the aluminium ones.

Main differences between aluminium external venetian blinds and PVC blinds

Now that we know what the materials are and their characteristics, let's go on to compare aluminium and PVC roller shutters taking into account variables to help you choose between one or the other material.

Durability and resistance

Secondly, when talking about resilience, resilience also includes the security. Aluminium is a metal that is resistant to damaging weather conditions and intrusion attempts from the outside. 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.


Whether aluminium or PVC blinds, they are easy to maintain. 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. However, if you are looking for differences, those of PVC allow the use of more productsThey are even easier to clean than aluminium ones.

Quality and service life

The quality offered by aluminium is better than PVC, especially in terms of impact resistance and durability. The service life of aluminium roller shutters is longer, especially if they are of high quality.


It is common for roller shutters in PVC are more economical than aluminium blinds. On average, we can find that the price of aluminium blinds varies between €50 and €170/m2, while PVC blinds have a price per m2 of between €40 and €150.

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.
