New smoke house safety question

[iloutdoorsman]

My father in law and I decided to build a dedicated cold smoke house for smoking deer sausage. This house will have to stay outside so we chose smart siding to cover the outside. With smart siding being similar to osb im now questioning that decision as far as safety due to the chemicals & glues used to make that product.. With that said, we had planned on covering the inside with cedar, maple or even aluminum or tin. Would covering the inside be safe or do we need to start over and build a cold smoker entirely from an untreated material?

Tried to attach a photo showing the material & the stage in which we stopped before continuing.

Thanks

Welcome to SMF
That is the $1,000 question. I don't have an answer
Many have built smokehouses with plywood interiors.

Bumping so others may reply.

Stop over at roll call and introduce yourself

Roll Call

This is where all new members should begin. Tell us a little about yourself, where you live, what you do, etc. Just helps us get to know you better;-)

I covered the inside of my smokehouse with hardi concrete board with aluminum flashing over that. The highest temp. I will take it to is 275*F; but mostly it is used for warm smoking large batches of smoke sausage.

HI! Smoker looks good!
I do not have any experience with this BUT!?
A few fabricators offer insulated cabinets that substain high heat!
Reach out to them for advice!?
Meadow Creek smokers is in ,PA.
Ask for Lavern in sales, he should be able to help you ?
It will do 2 things!
Keep yur smoker @ temp.
Keep the heat away from yur exterior .
Find an insulation that is heat tolerate .
I believe you said smoking?, so it should be below 300 F ?
Thought about adding other stuff? <but I think it would ruin the exterior and whole process.
EX: METAL will hold the heat? Not Good ?
End of the day:!?
Use some decent insulation and then add a covering over it?
Not sure what ?
Good Luck SIR!
ELF

I would not have chosen the OSB as its just full of glue, but if only cold smoking probably not a problem. I'd worry more about it if you hot smoke.

How are you feeding it with smoke and assuming you're using #2 cure?

I'd like to cold smoke with mine but the fire box is a bit of work to keep the temp down just 6' away.

I’d be a little worried if the heat was going directly onto the OSB, but if you have a fairly tight liner, say metal or even tongue and groove cedar, even if the glue gets a little warm and starts gassing off, all the vapors will go to the outside since the heat is traveling from the inside to the outside not from the outside to the inside…

Gonna try out a smoke daddy magnum pig cold smoke generator, see if it will smoke enough for a large box. Smoke daddy says no issue..

NOT OSB for the reasons already stated. At some point you may WANT higher temps in there and you won't be wise to do that as the OSB is not a safe choice.

Heat significantly accelerates the off-gassing of volatile organic compounds (VOCs) from Oriented Strand Board (OSB). The resins used to bind wood strands, primarily phenol-formaldehyde (PF) or methylenediphenyl diisocyanate (MDI), release formaldehyde and other chemicals at increased rates when exposed to elevated temperatures and high humidity.

• Temperature Sensitivity: High temperatures speed up the breakdown of the resin binders, causing a faster and more intense release of residual formaldehyde.
• Humidity Factor: High humidity works in tandem with heat to promote resin hydrolysis, further increasing VOC emissions.
• Safety Risks: Burning OSB releases toxic fumes from these chemical binders, making it unsafe to incinerate. Additionally, in fire scenarios, heated OSB releases combustible gases that can contribute to rapid fire spread and flashovers.
• Mitigation: To reduce off-gassing, maintain low indoor temperatures (below moderate levels) and keep relative humidity below 50%. While sealing OSB with paint or sealant can slow the release rate, it does not permanently stop off-gassing once the material is cut or damaged.
