Project for the Summer

Hi Huck. Looks like it could be an easy fix if you can get the materials in your neck of the woods.
HomeDepot and Lowes sell a product made for wall applications in moist or wet areas such as janitorial rooms and restrooms. Its a fiberglass sheet good that is usually in the paneling section. We have it in Almond or white.
It appears from your pics that the sheet thickness should be very close to the same. It cuts very easy with a utility knife and a staright edge. Although they sell a knife for scoring the sheet.
I hope that gives a little food for thought.
Good luck on your project.

Huck I was going to suggest a product from Home Depot, that is 1/ thick, that has a melamine type coating on it, that allot of people use to redo their showers with. It is kinda like Masonite with melamine coating. It is fairly cheap also. Just a thought!

Except that using that 1/4” stuff will “cave in” from snow buildup come winter. Wreck the wall out. Rebuild the halfwall (kick panel) using pressurized 2×4’s and T-111. Even with pressurized wood, a stain/sealer is a must. No more water or snow worries. As for the top, I’d consider placing “removable” windows or glass panels (then you can enjoy the room in the winter) and screen panels for summer.

You could try to enclose them with tempered glass. It would add more light as well!
