Glass Block Pond Window

[NicodemusBC]

I searched and searched but couldn't find any thread about this.

I was just at the hardware store and saw perfectly clear glass blocks, meant for use in bathroom windows. I've seen these blocks used in pools, usually to make the transition between a jacuzzi tub and the main pool, so they have some strength. They were about $4/ea for 6"x6" blocks.







I know mortar messes with your ph a bunch but one could use a thin piece of acrylic on the inside of the pond as a liner that'd be siliconed in (or whatever is the apropriate adhesive). Or paint the mortar with Pond Armor?

I'm imagining a cinder block walled pond with some of the blocks replaced with these clear blocks. It is feasible that one could also silicone over the mortar joints on the inside.

I also realize that glass can grow algae, but this'd be true with the traditional window styles.

So, is this possible?

I couldn't find a picture of a window using these kind of blocks but here's one.



It seems clear enough to be worth a shot especially with large fish and a decently large window of them.

So there is a system that uses plastic strips and silicone to glue glass block together that requires no mortar. The problem I see is that glass block is not like other masonary systems in respect to it is not load bearing. The reason it works int eh first pic is it has equal pressure from the water on each side. If you used it in a viewing window application it would be more prone to failure.

I would just use a traditional piece of plate glass it has been done many times adn not that much more expensive by the time you add the cost of the block mortar and extra time installing the blocks and keeping everything level.

none of our viewing panes are load bearing...that argument makes zero sense to me. why would you think 3/4" - 1 1/2" plate glass would be any stronger than 3" glass block? In fact it wouldn't be anywhere near as stong as a similar distanced glass block contruction.

the only think that does make sense to me is cost. I'm pretty sure you can get the required plate glass cheaper than any decent length glass block construction. the plate glass would also be easier to install and give a better view.

it in no way however is going to be stronger than glass block.

No....The hot tub is elevated above the pool..
