Exposed ceiling insulation in helicopter hangar

Archive of Older Topics Archive - Product Discussions #6

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.

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 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 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.

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…

If anyone knows of something even better let me know!

Thank you much,
Trevor

Take a look at Monoglass (https://monoglass.com/).

Look at the Simple Saver insulation and liner system 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.
