Going to try something new this year. Traditionally I have used 1/2" Baltic Birch for my building construction, and then used TightBond III to glue up and coated it over everything as a waterproofer. Has worked well in the past… Since the Russian Invasion of Ukraine that stuff has dried up except at over $100 a sheet now.
So this Year I’m going to try using a product from the sign industry for outdoor signage. It’s two sheets of thin Aluminum bonded to a plastic core. The stuff I got ahold of is brand named “MAXMETAL”, but there are other brands of the same product.
From their web site:
"ACM, or aluminum composite material. Comprised of two, pre-painted .15mm aluminum panels bonded to a solid polyethylene core, it is lighter and more durable than MDO and solid aluminum panels. The low mineral core makes MAXMETAL™ easy to fabricate, and its low thermal conductivity allows for a quick cool down.
Cuts on the hand or table saw, and can be router cut or milled… 100% weather proof.
Will have to figure out how to work it, and mount the corners together…
Stand By…
