Blow-in insulation behind pegboard?

[EddieWalker]

Congratulations, that's going to make a huge difference. How many bags did you use? Was it enough to get the free rental of the machine?

How are you going to put the plugs back in? If it was me, I would rip some half inch strips off of a 2x4 or 2x6 several inches longer then the size of the holes. Lets guess that they are two inch holes. I'd want my strips of wood to be 6 inches long, 1 1/2 wide and about half an inch thick. Then I would put it across the backside of the hole and screw it into place from the front side. Then screw a plug into the wood to fill the hole. Caulk and paint.

3 bags .... a little short of the 10-bag free rental. I rented for 4 hours, an it took exactly 4 hours. The remote switch didn't work so I had to remove one shoe & push the start-stop buttons with my toe (for the upper holes). I ran out of insulation with one cavity remaining, so swept the floor and that almost filled the last cavity.

That's hundreds of screws, and it would still be a row of plugged holes. I'll cover the lower row with a 1x8 "belly band". And the top in a similar way. The flat roof is 4 inches higher at one end so the upper band is a taper.

With no heat it was already warmer than the next bay. I will paint the floor, any favorites? Epoxy? I want something that sticks hard, and tough too. There's one narrow crack the whole length. It's not straight, it's a real crack about 1/16" wide and 24 feet long. Should it be filled first?

Sounds like it all worked out for you perfectly. When I do a house, I buy the insulation by the pallet since it's all wrapped and ready to go. Three full pallets is a lot of insulation, but I never use it all. They never charge me anything until I return what I don't use with the machine.

Built the workbench structure today. That's all square tubing 2x2x.063.
Front legs bolted to the floor, rim and back legs screwed to the wall.
Dang outlets were at a crappy height so abandoned them. Will cover with a backsplash. Benchtop height is 40".

Yep dangit there's fireblock. I'll cover the blow-holes with a belly band, will put outlets in that. Belly band will be level - pegboard holes are NOT level. I'm not happy about that.

I have a new shop. This is good! REAL GOOD! One bay is walled off, with a door, so I thought I'd put a woodstove in that bay. It has pegboard on ALL walls, nailed on with galvanized drywall nails with the thin heads. I don't know if I like pegboard, cuz I yank tools & the hooks fall off (I think). Perhaps I can learn to like it. One guy said paint it white anyway, then the pegs will have to jam in, and will stay on.

It has no insulation in the walls behind the pegboard. It would be very easy to blow in the insulation on 3 walls, I suppose all done in one morning.

SO...can I blow in insulation into the walls behind the pegboard? Will it stay put? There will be no vapor barrier, but theres no shower or cooking or steam in my shop, no people sleeping etc - it will be cold most of the time, heated perhaps twice a week - if that.

Does blow-in insulation have fire resistance? I was thinking of a welding spark diving into a hole.

Hoping someone has experience with this. I need to make some decisions before I move in. Can't do a lot of work on it, have other fish to fry. I need a new workbench too. Soon, house projects will be TOP priority and its gonna be a long haul.

Blown cellulose does not have a listed fire resistance, but the borate chemicals that it has been treated with makes it fire retardant. Means the stuff will still burn, but you'll have to try harder to get it lit. Blown fiberglass insulation will also fire retardant, but I'd be more inclined to use it where welding sparks could get into the insulation. Mineral wool is fire proof. Some spray foams can be fire retardant, none are fire proof. Most board foam burns and smokes horribly and should not be used unless it's covered with drywall. Isocyanurate is the one exception to this.

Couple of thoughts: rodents LOVE insulation so you need a way to keep them out of your wall cavities. What are you going to do for a vapor barrier? You really should have one on the inside face. With closed cell foam, a vapor barrier would not be required, but you should have one with the other insulation types.

I don't see evidence of rodents, hope the future holds the same. Not sure what to do about vapor barrier other than limiting the vapor produced in the shop. No showers, bubble baths, or cooking down maple syrup.

Heres what happened soon after.
I built my workbench.

Fuzz in all the holes looked a little shabby.
My tools have been in a rollaway for 20 years.
I know where everything is.
I started thinking about how unlikely my 'shop style' was to ever actually
--buy all the hooks
--choose a layout
--spread all my tools all over the walls.
I would never do that.

I can see how pegboard would be very useful to a specialist/professional, but just try to start visualizing an arrangement for efficiency of varied non-professional tasks.
It can't be done, and the moment I tried to start arranging it became obvious that pegboard is no benefit for me.
In reality just a hassle. (for my personal shop style)

So I unbolted my new workbench, and buried all the pegboard under drywall, and reinstalled the workbench.

I hate pegboard... looks a lot better now IMO. Gonna be cleaner and brighter too.

That's a huge decision, but I think you made the right one. I've never been a fan of pegboard, but figured that it has it's place and I was looking forward to seeing how it worked out for you. The difference in how your wall looks with the pegboard and then with the sheetrock is significant. Thanks for the update!!

Thanks Eddie.
I did NOT want to mud & sand drywall.
But obviously in the end I had to.
I grumbled while doing it, but in the end the shop looks much nicer.
And now that I've been here 3 years I want to tear the whole thing down and build a 'real' shop.
