Have you ever seen this corporeal on your jobsite ? I ’ thousand talking about the white foam that is going through the wall in the visualize here .
This is an HVAC argumentation set called Isoclima or Isopolar. You can check it out here. During a holocene site walk, we ran into this. I had never seen it before, so obviously I had heaps of questions. I figured it would be simpleton, contact the manufacturer and get the information we need.
What information do we need ?
well, we know there is a humble copper tube inside the insulating material, but since it is not authorize what character of foam material the insulation is made of ; it is not possible to identify what UL Listed detail we can use. The chilling part is that whatever insulation this is, may have never been tested in the foremost station. even worse, there are some types of insulation that can not be firestopped at all because they won ’ t survive the fire test. ( ASTM E814 ) .
so, I thought it would be easy, just email the ship’s company and ask what material is used for the insulation ? ….Has it been tested for fire spread and fastball development ? Has it been tested to ASTM E814 ? Three simpleton questions that let me know how to move forth .
The trouble, is that the manufacturer has not responded. I have emailed them once a week for the last four weeks and I receive an automated e-mail reply thanking me for my question. I have four of them sitting in my in-box but not a single reaction to the questions I posed.

That can only lead me to believe that they have not tested it to ASTM E814, which means there are no firestop details. That ’ s not a HUGE cover, we just need to get the proper paperwork from the firestop manufacturer, except they are going to want to know what the insulation material is and we can ’ triiodothyronine share that information with them because the caller who knows has been absolutely non-responsive .
If you find this material submitted for use on your jobsite I would not allow the practice until you can confirm it is possible to firestop it when it passes through rated fabrication. Bear in beware I am not saying that you CAN ’ T use this. I ’ meter precisely saying, without the proper software documentation, you are creating a fantastic placement indebtedness. As you make this choice you should besides be mindful that some of these foam insulations are incredibly flammable. Which makes me want to snag a rubbish and see what happens when you try to light it. If I manage to get sample and do my examination, I will keep you posted. If you decide to do this, be certain to have a fire fire extinguisher and/or a bucket of water and remove anything combustible from the test sphere. Be safe, but let me know what the results are .
In the meanwhile if you encounter anything new on your jobsite and you want to know more about how to firestop it properly…please send me photos and information so we can contribution it with others who are interest .
All the best and thanks for checking in with us !
