There are many different types of wall systems available on the market today. There are two distinct differences of all of these wall types, Progressive or Non Progressive. Depending on your application you may want to determine which type best suits your needs and why.
This section primarily applies to buildings whether it is in single story form or two-story. These enclosures would primarily have a dust cover, roof or second floor attached to the first floor. When you use these walls as just partitions with no load on the wall, Non Progressive wall system may be more suitable.
To put it in its most simple form, A progressive wall system indicates that you will have to start at one end working progressively in a linear motion until it ends. One example of this would be standard drywall construction framing. The drywall sheets can not be just removed at will when it’s convenient. Another example would be a brick wall. Each brick must be laid on top of another with mortars separating it and bonding it together. When you see these types of construction, you will see that where the opening was planned, there is an opening supported. I will get into that in more detail bit later.
A Non Progressive indicates that you can start and stop at any point and work in any direction. When removing any portion or section you can start at any point and end at any point. One example could be… Hmmmm I can’t think of any..
Although this may sound simple there are many things to be weary about when making this decision. Making the wrong decision could be catastrophic in the future. There are pros and cons for both depending on your application. Your designer must be aware of your application and plan around your future decisions.
When you’re planning to build a structure of any type, the most important thing is the structure! That may sound very simple and almost stupid. Believe it or not a lot of people do not consider the overall structure and application. Let me go further.
Do you know of any structure that will stand up when you remove sections that are holding up the roof? They’ll be no sky hook to hold it up…. your answer should be none. You’re exactly right. Planning to remove wall sections in the future is the way the building should be built. Having removable sections where you planned to have removable sections. And leave the walls that are the overall structure holding up the roof.
So, when you hear the phrase “Any panel can be removed without disturbing the adjacent panels” be very cautious. Was this planned to be removed?. If not, don’t remove it. It’s like removing the load bearing wall inside your house and expecting the roof to stay up. It won’t.
You need to work with a designer and think one or two steps ahead on what your future maybe in your facility. Making a removable section is fairly straightforward. Most companies can work around these issues. Using large spans, and additional support most applications can be engineered around your growth.
A progressive wall system should be used as support for any roof. This alleviates the risk of a company representative removing panels at will. Even though the wall may be progressive, most factory Representatives can change out wall panels in the middle of the wall.
Allied Modular Building Systems manufactures both types of channels. We only use the removable “Non Progressive” where necessary insuring safety for all…
