You can try to get outdoor signage material, but I think if you try to do all sides flex will be an issue. You can try something like this, it is likely what is used in the insitu tanks rear wall. (Alumilite), PVC with aluminum sandwiching each side. Supposedly easy to drill and is lighter than glass.

Thank you for your responses!
PVC flex is something I am definitely concerned about.. I have read anecdotally that in Europe a lot of vivarium makers use "cellular-core" PVC, instead of regular PVC. The foam core would give the material more rigidity than a plain pvc sheet, but I am concerned about durability and the potential for them to "snap" like foam boards tend to. I am looking at the three products below. 1. Ultraboard classic- if this material works, would be FAR less expensive than building out of glass. Edge banding available, but I'm not sure how bonding would work with the foam core. https://www.grimco.com/Catalog/Products/UltraBoard 2. much more expensive but still cheaper than glass. This product does not require edge banding and i think bonding would be more straightforward. https://www.grimco.com/Catalog/Products/DUNAHDU20 3. Same as option 1 but with aluminum faces. https://ultraboard.com/product/ultraboar...ore-sheet/ Any comments on the above would be appreciated! Also, does silicone bond to PVC??

Here's the build thread from DB:

Thank you all for your input!
I settled on Duna Corafoam HDU, 15 lb. weight. You can see this product here, although the provided pictures on this site don't show what it is capable of- https://www.grimco.com/Catalog/Products/DUNAHDU I ordered 1 4x8 sheet each of 1/2" and 1". 3/4" is currently out of stock near me. Supposedly this product can be worked just like wood, will bond with cement, but should be much more rigid than plain PVC because it is technically an extruded foam. I will update this post once I get the sheets in (They will be delivered *free shipping* on Tuesday). Thanks again!

If you are looking for PVC materiel like what Phil's vivs are made out of I am pretty sure you want to look for PVC Foam Sheeting.
This is the material: https://www.piedmontplastics.com/product...foam-sheet Most plastic places can order it for you since it is very common and typical wood working tools can be used to fabricate it. The solvent you will need is WeldOn 2007: https://www.paragonplastics.us/product-p...007-pt.htm I priced some out at my local plastics place and a 1/4 inch thick 24 x 24 sheet was $35 and mine will custom cut different sizes and finish the edges for not much more. I am also looking at a this material here that is aluminum sandwiched around a polyethylene core. https://www.piedmontplastics.com/products/acm A kickstarter campaign to make vivs out of that materiel was kicking around for a while earlier this year but died on the vine. They were CNC cut knock down flat ship kits that you put together yourself using alignment tabs and screws. A little bit harder to work with and sealing seams would have to be done mechanically with silicone sealant. |
