Hi, I have a VB hangar project - stated from the record drawings. The ceiling and walls use a corrugated metal panel. We’re adding a paint booth and upgrading the coolers to heat pumps. The client would like to insulate the hangar with a batt product. There is an existing AFFF fire suppression system. Has anyone used an insulation covering, or sheet product that has a low flame spread? I see this in exposed ceiling projects that seem pretty trendy right now. I’ve searched for this but must be using the wrong term. Any ideas? Thank you, Trevor ---

Check out FSK insulation. ---

try searching for “intumescent” coatings; sometimes used in conjunction with spray foam insulations. ---

Hi David, That FSK is pretty neat, thank you. Have you used wires, or something to keep them against the deck? Have you ever used a blanket type wrap? The reason, I’m asking is the spacing of steel joists is not the same as wood framing, or steel studs. Trevor ---

Why not try a semi-rigid mineral wool board insulation with a facer (Owens Corning’s Thermafiber Versaboard for example) and welded stick pins for attachment/support with a domed cap retention washer? ---

Guest, [http://isolatek.com/rigid-board-app/#videostab-tab](http://isolatek.com/rigid-board-app/#videostab-tab) that’s a pretty clever clip system. The versa board is a good thing to know about. My sense is they are looking at the batt type insulation due to cost. The roof is arched, not sure how “bendable” a board product is. Right now the [https://www.jm.com/content/dam/jm/global/en/building-insulation/Files/BI%20Data%20Sheets/Resi%20and%20Commercial/BID-0147-FSK25-BioBinder-DS.pdf](https://www.jm.com/content/dam/jm/global/en/building-insulation/Files/BI%20Data%20Sheets/Resi%20and%20Commercial/BID-0147-FSK25-BioBinder-DS.pdf) may be most in line with the client goals. Are the fabric-type sheets that hold insulation up generally for that purpose, or are people using different things to give the insulation a neat appearance? It’s very possible I’m looking for something that doesn’t exist… Appreciate everyone’s thoughts. Trevor ---

This may be the most appropriate. I’ve enclosed a cutsheet. The FSK-25 was perfect, but for stud walls, and standard width framing. I called JM and this metal building insulation has the flame spread 25, smoke 50 and has a facing that can overlap… [https://www.trevorpan.com/stuff/AirMethods/Microlite\_L\_MBI\_200.pdf](https://www.trevorpan.com/stuff/AirMethods/Microlite_L_MBI_200.pdf) If anyone knows of something even better let me know!

Look at the Simple Saver insulation and liner system [https://thermaldesign.com/products/category/simple\_saver/a\_simple\_choice](https://thermaldesign.com/products/category/simple_saver/a_simple_choice) We’ve used it numerous times with good success on gymnasium buildings and natatoria. ---

PVC is intrinsically fire resistant - it melts but doesn’t burn first. Use perforated PVC if no vapor resistance is required and unperforated if it is. Phil’s recommendation is a good system.
