I primarily used 15 series (1.5 in) I have a small storage behind the passenger seat from 10 series (1 in) and folding table from the Quick Frame (1 in) profiles. I was contemplating using a combination of 10 and 15 series pending loads but added complexity swayed me away.
Bulk of my HDPE is 1/4 in, so some sides, some bottoms or fronts are ľ in. Drawers fronts, door cabinets, and some countertops are 1/2 in. Galley's countertop is from 3/4 in material. HDPE is not used as a structural element; strong aluminum frame is more than sufficient. For example, none of the cabinets' rear side have HDPE except for containing cargo in storage compartments or for mounting components. Overhead cabinets have 1/4 in bottoms and 1/4 in sliding doors.
Very often I am asked about the potential vibration noise, a 0.25 in thick HDPE is placed in the are 0.320 in. 15 series profile slots, so rather loose. For fixed cabinets I use the 80/20 silicon gasket, about 1 in strips every 6-8 in apart. For sliders, I used a specific fishing line threaded through small holes on the edges. Works great for the last 6 years.
