What are metal blinds?
Metal shutters are protective elements for windows, doors and entrances, generally made of aluminium or galvanised steel. These are rolled up or folded to open or close the protected space.
They are commonly used in commercial and industrial buildings, as well as some homes, for their strength and durability properties. In addition, they offer good thermal and acoustic insulation, reduce energy costs and increase interior comfort.
What types of metal shutters are there?
Aluminium Roller Blinds
Aluminum roller blinds are very popular thanks to their ease of use and resistance. They are rolled up in a box located at the top of the window or door and can be manual or motorized.
Aluminum Security Blinds
These metal roller blinds are specifically designed to provide additional protection against intrusions and theft. They are made of particularly sturdy materials and often include additional security locks.
Fixed Slat Aluminium Blinds
Composed of fixed horizontal slats that cannot be adjusted, these exterior shutters are ideal for buildings that prioritize safety over visibility.
Movable Slat Aluminium Blinds
Unlike fixed slats, these blinds allow you to adjust the horizontal slats to control the entry of light and maintain privacy.
Microperforated Aluminum Metal Blinds
These blinds employ perforated metal to provide protection while allowing for good ventilation and visibility, making them ideal for commercial spaces.
Advantages of Metal Shutters
Safety and security
Metal shutters are extremely resistant and difficult to force, offering an effective barrier against theft and vandalism.
Privacy and sun protection
They allow you to regulate the entry of light, providing privacy and the possibility of creating more intimate environments.
Thermal and acoustic insulation
They act as an additional barrier against inclement weather and outside noise, improving interior comfort.
Which metal shutter should I choose according to my intention?
Fire Blinds
These blinds are designed to resist high temperatures and protect against fires, being common in commercial and public buildings.
Acoustic
Specifically designed to reduce outside noise, they improve sound insulation inside.
Insulating
They are made to improve thermal insulation and reduce energy loss through windows.
