How are you patching your 1 hour rated walls?

Today’s Topic- How do you properly patch a one hour rated wall?


Hi everyone. I hope you are doing well despite the lock down and virus. We are breathing easy over here and I pray that the same is true for you, your family and your teams.


I have been capitalizing on this time to develop a new skill and I can’t wait to share the results with you. It will be some training videos.


One of them will discuss the difference between regular drywall and type X, another will talk about type X drywall vs type C.  Since that is all coming down the pike in the next week or two, I wanted to share somethings that will compliment that discussion.


Once you have built a rated wall at some point in time its likely SOMEONE will poke a hole in it. This could happen during construction if someone decides to relocate a pipe for example.


So how do you patch it. If you ask the Gypsum Association, this is how you should patch a rated wall. Please take a moment to look over this so you understand. One of the videos that will be coming  will talk about how rated walls are tested, but the one that I hope to get to you first will talk about the difference between regular drywall and we will have a complex discussion about fire dynamics that is actually kinda fun. For now, I will leave you with this from US!


Next week we will talk about how to patch a two hour rated wall, because those are really different.



Why the way Fire Rated Assemblies are Tested SHOULD Impact How you DESIGN, BUILD & INSPECT?

Most people in design or construction have never wondered, “gee, how do you test a fire rated assembly?” But if you don’t understand how the assemblies are tested you might not be designing or building the way you should. This series of videos will introduce you to how fire rated assemblies but we will take it a step further and who you how that could play out in a real wold scenario. It is our hope that this four part series will help you improve how you either design or build.


Shaft wall joints and fluted deck- recipe for bad firestop.

Firestopping on shaft wall assemblies is done wrong way too often.

If your project has fluted metal decks, you are likely firestopping the shaft joints with mineral wool and spray. If you want to know that your team is doing it right, this video can help.  

If you have any questions or need any extra help, just give us a shout. We are happy to help anyone who wants to get this right.


Are you building Shaft Walls right? Part 3 (Head of wall- Sealant)

Firestopping head of wall joints seems basic, but its shocking how often something so basic is done so wrong. If your project has shaft walls and you are fire stopping them with sealant, please watch this video, so you can be sure the installations on your projects meet the requirements.

First thing to check- Do your firestop submittals have shaft wall details? If not, they should. If not, there is a considerable risk that the fire rating of your shaft walls is missing the requirements we point out in this video. If you want to know how to avoid this liability, this video is designed to help.


Are you building Shaft Walls right? Part 2 (Build It)

Welcome back, clearly you are one of the teams who want to be sure you are building right. This series is addressing shaft wall construction because it is so critical to the life safety of your projects.  The last video talked about how shaft walls are tested differently so that when we talk about how they are built differently, in this video, you have a different level of understanding of why things are important. Check it out here!


Are you building Shaft Walls right? Part 1 (Test It)

You know shaft walls are built differently than other rated wall assemblies, but did you know they are tested differently too?  Understanding this difference will help you understand why the need to be fire stopped differently as well.  Shafts are critical to the life safety of your buildings. They impact multiple floors, so they deserve a little more attention. This video series is designed for those of you who want to do things right. We hope this will make it a little easier for you to understand how to evaluate field installations and ensure they are built properly. Check out the video here and if you have any questions don’t hesitate to give us a shout. We are happy to help if we are able.

Thanks for your time.



Four Rules of Firestop Spray- Know them- Follow them!

Firestop Spray at head of wall joints is an installation that can look professional or it can look like a blood bath. This video will help you know, regardless of what it looks like, if you can expect it to perform in a fire scenario. We walkabout what to look for but also WHY each element is important. You can see this new video here. Please let us know what you think about this and what other topics might be useful for you. If we can help on a project, don’t hesitate to give us a shout!


Coffee Break Firestop Training Series

Welcome to our Coffee Break Training Series. Do you look at firestop at head of wall joints and think its easy or basic, what about shaft wall construction or other rated joints such as bottom of wall or wall to wall joints? If you think they are basic, this video series may help you see these installations in a new light. If you have a means of egress shaft built of gypsum wall board, PLEASE watch the one on bottom of wall applications because you may look at exit shafts a whole new way after that video. There is A LOT packed into this multi part series and despite the fact that we are talking building codes and fire test standards, you might actually enjoy yourself, but you will definitely learn something. So, welcome and I hope we can help you look at firestop a whole new way.  Here is our introductory video- see you next week



Firestop Special Inspection- Reducing Confusion

Firestop special inspection is a relatively new requirement in our building codes. This three part series is designed to help architects and building officials understand how this code change impacts their responsibilities. Understanding how to verify that you have someone who is capable and qualified to do this work for your team is critical and this video is designed to help. While we are not digging into the requirements of the building code or the inspection standards this information is from the ICC Special Inspection Manual.

Our first video in this series will show you an easy way to confirm that your special inspector meets the requirements of the inspection manual. The next two videos to follow will explain the responsibilities of the building official and the architect as they are called out in the ICC Special Inspection Manual.

If you are an architect or a building official, we hope this video helps you do your job a little more easily.
