Which Material Should You Go with For Your Security Louvers?

Which Material Should You Go with For Your Security Louvers?

There are various louver materials to pick from depending on the kind of building and its security requirements.

Choosing to have security louvers installed to help maintain and control air movement throughout your house or business will prove to be an environmentally and economically smart decision. Louvers are normally manufactured with plates that adjust either manually or automatically to guide air through a building and a block if needed. They’re often used for security, airflow, and protection in individual rooms too. After they’ve been set up around HVAC units, commercial facilities, or other air handling equipment, they can work to secure buildings and airflow. There are various louver materials to pick from depending on the kind of building and its security requirements. Read on to learn about a couple of the most common materials that are used for security louvers!

Stainless Steel

Stainless steel security louvers are an excellent choice for a few industries and needs. It is proven to hold up all of its strength under even the most drastically high temperatures. It has excellent durability, resistance to flexibility, and corrosion, which makes it quite useful in many situations. If you are looking to place a louver in a building that requires certain conditions, such as labs or pharmaceutical processing plants, stainless steel might be a good material for you to consider. It also retains its shiny appearance without being painted or anodized. A downside, though, is that they can be a bit more expensive to produce.

Aluminum Security Louvers

Aluminum louvers are a very low-cost alternative that are even easier for your business to maintain. Aluminum does not rust and is noted for its corrosion resistance, allowing louvers produced from the materials to have a long life and keep its original aesthetic appeal without breaking down from the elements. A considerable advantage of aluminum is its ability to be fully recycled and reused multiple times without ever losing its properties. Aluminum dampers are very flexible, durable, and much lighter than a louver created from stainless steel. While aluminum is strong enough for various types of equipment, you should also consider that it isn’t as strong as steel, and it tends to expand when in higher temperatures.
