Title: Drop ceiling or open
Post by: islandtees on September 27, 2014, 07:08:20 PM
We purchased a building that we are fixing for our new shop. It has open 14ft ceiling in the center and goes down to 8 ft on the ends. We want to a/c the area(about 3600sq ft) We don't know if a 8ft drop ceiling would feel cramped. I like a drop ceiling myself or we could spray foam the roof deck and leave open. Those that have a 8ft ceiling , do you feel cramped?

Yes! We don't have 8' they are 14' but I see some pics of shops in big warehouse spaces and get SO jealous! 
Higher ceilings also gives the heat a place to raise to. A large exhaust fan at a high point is also a plus.

I have 10 foot ceilings and find I OFTEN wish they were a little higher.  14 would be awesome.

My concern with the higher ceilings is the A/C. It would take a lot more tonnage than the lower ceiling and much higher electric bill.

Your money may be better spent enclosing your dryer in a "room" with lots of insulation. This will reduce a lot of heat and also save on your gas bill. We actually wrapped our dryer in extra insulation a few years ago, it helped but also made many of the plastic knobs brittle. A surround made out of 2*4's and insulation with a exhaust fan up top will do volumes. It is hard as hell to A/C a shop...

We have a drop ceiling in out shop. I pulled every panel out this summer to hopefully get some relief.  We have AC but the dock doors are still always wide open in the summer

If you have a/c, why did you remove the panels. I don't understand?

We have an old Raypaul. 12' of heat which equates to hotter than hell.  Shop is about the same sq. footage as yours
The AC never keeps up with that size of dryer. Plus we print a lot of fleece which ends up being like mounds of heat sinks everywhere in the shop

Since the a/c units are not installed we would be going with 2 units and can up the tonnage for heat gain. We just cant deceide on a drop ceiling of 8 feet or leave it open at 14 center and 8 on ends. I have to sacrifice height for less tonnage of a drop ceiling, that's why Im asking those with 8 foot drop ceiling how does it seem . We have auto and manual machines. I just don't want to feel like were in a cave.

If it's an option, go with expanding spray foam insulation.  It is expensive on the front end, but BIG savings later.

I have open cell in my storage unit and it does well.  I have a client that probably has closed cell on the underside of his homes roof and he keeps his av equipment (amps and such) in his attic because it doesn't get higher than like 90 degrees.  Keep in mind everyone's attics around here push like 150+ as we are in southern Louisiana!

Now that I own my building I'll likely be looking to get open cell sprayed on my roof... Even with the radicure and a quartz flash back it gets a bit warm.  I'd rather spend ~$3k on insulation vs $1000+ on a mini split and trying to find or add another electrical box to fit it in.

8' is too low in my opinion. Is your dryer and flashes under the current 8' sections? What dryer are you ruining? Even if you finished off more of it with a lower ceiling and left a spot open going all the way up, a good amount of your heat will collect there, then you just need to get a way to get it out of there.

A/C or no A/C 8' is just too low if you have other options.

I was thinking the boomerang dryer from M&R would be cool to wall off in the hot side and have the shirts return to the cool room.

If we go open ceiling we would also go spray foam. I agree, that stuff is amazing. If I go that route(very expensive because I would have to get the fire proof coating because it would be exposed) than I would also need bigger a/c units for the additional volume. Im trying to weight all out. Are you talking about the foam inside the roof deck or outside the building on the roof. I was looking at inside foam.

Inside... Underneath the roof itself.

The last place I worked at had the screenprint operation in a building with 8ft ceillings. We ran an auto and a Mini-Sprint in there. It never occured to me that it felt "cramped" in there with low ceilings, but I can say that those low ceioings afforded a pleasant climate-controlled area. I would do the same in my shop if I owned it, but we lease the building.

You can get used to anything after awhile, I'd be happy to get used to a low ceiling and a temperature reading of less than three digits.

What dryer are you running? When we only had a workhorse 3011 it was super comfortable. with the Raypaul it's a min. of 80 degrees with the air running.

We have a M&R Fusion dryer (10 ft heat chamber) so not a huge dryer.

We do tons of garment dyed shirts.  30 foot ceilings are still not high enough.  The smoke/fumes from the dye is terrible.  I would go for the high ceilings.

Do you have a/c and how do you get rid of the fumes with that high ceiling?
Title: Re: Drop ceiling or open

No A/C but lots of air flow.  Temp rarely gets above 90.

I want to think ours are 30'. Lot of discharge products roll through here each day. But we knew that when we built the factory

we have AC and low ceilings. You will have minor problems with the small electric dryer. If you wrap it well, you should be OK and it should not impact your electric bill much.

discharge and small enclosed space do not mix, you will have to ventilate so all your cold air will be gone!
Shorter ceilings are better as the air volume is lower so it will cost less to cool and it will recover faster if you have to blow the fumes out.

With both the small and the large dryer we ended moving the output through the wall into the warehouse. You will need a way to manage the smoke/fume output. Make up air is the way to go if you are building your own.

The problem I see with the dryer is a lot of heat comes out the exit end of the dryer. The dryer does have the power exhaust toward the end which we will ventilate outside.
We don't do discharge or waterbase, plastisol only.
The building already exists.

We have two 6 foot exhaust fans adjacent to and above the rec dock. On the far opposite end and in alignment with the fans are giant louvers. There are also louvers located on the East side of the building.
When the fans are activated the louvers open in tandem automatically. Pretty functional. But when you run those Chouinard pig dyes all bets are off and the funk begins. Thankfully they mostly do not  discharge well or at all so most people do not order them. Discharge fumes not a problem except with the Magna white recently.

Sounds like you just need better ventilation. Put some range hoods over the end of the dryer and vent that outa there.
