Cleanroom Construction

I am currently in the process of constructing a new cleanroom. So far, it is approx. 9'X8' with a floor that was painted with a two-part epoxy. The ceiling is a T-grid system with 3 2'X4' HEPA ceiling units. The walls are my question. Right now it has one masonry wall(dry-lok painted with two coats) and three framed walls with vents at the bottom. I am trying to decided what to cover the framed walls with. Do I use FRP panels from lowes(fiberglass reinforced plastic like in a shower) or do I go all out and get 3-ply aluminum cleanroom panels. This is intended for high production spawn lab. Cost is an issue but I am looking for other reasons to go with one or the other. Would love any other suggestions for wall covering as well.

IDK, I would go for fiberglass. Aluminium tends to oxidate (after that it get bumpy. FB is glossy and more easy to clean.

What does the aluminum run? I think frp is abt $30/sheet (4 x 8). It is acceptable for use in commercial kitchens, and I think there is nothing wrong with it other than cost. What's wrong with regular old drywall with 2 or 3 good coats of paint? That would be a lot more cost effective as 3 out of 4 of your walls are going to have sheetrock under the frp anyway, right? Some mud, tape, and paint will finish the walls up nice. Good semigloss will stand up to washing. Curious to hear what you decide.

Actualy I would not recoment drywall even for home usage. I've heard that after some time drywall starts "disintegrating" with micro drywall dust, that can cause some breathing problems.

If cost is the main an issue I think looking into high performance paints you could use over the existing structure would be the cheapest option. That said if it's a high production lab I'd go for the FRP or aluminium, it'll be more resistant to wear and tear and it'll look nicer. Could be something to consider as you'll be spending a long time in there.

I would about bet you are living inside sheetrock walls, can you breathe easily? It doesn't magically disintegrate for no reason. It doesn't like to be soaked, but that's one good reason to paint it. Then you can wash it. The only health issues I've ever heard of is cheap chinese drywall that had horrible contaminants in it. To the best of my knowledge you can't buy that anymore.

I wouldn't worry about expensive high performance paints. Sounds like proper paint( block sealer) was used on the masonry. Epoxy on the floor. Sounds like the fancy painting is done. Semigloss would be fine over drywall, and inexpensive. I personally am anti rammy jammy in the clean room as I am working with hot delicate things in front of an expensive filter. If you were to trip and throw the all american through the wall, it would be quick, easy and cheap to patch up. I give the frp way more cool points, but wouldn't find it necessary at all. Paint, mud, tape, and drywall would come in at less than $10 per 4x8 sheet. Frp, frp trim, glue, and the drywall you put underneath it would be well over $35 per 4x8 area. If frp was the final choice, I would recommend keeping some mineral spirits handy during the gluing process. If you get that stuff where it doesn't belong and wipe it up QUICKLY the mineral spirits will cut it. If you give it a minute or two to skin over, it becomes much harder to clean up.
