For the first new run of tests I'll mostly be focusing on CLD type materials. However, after those are done, I will likely get some more panels to test other materials, such as spray on materials, etc.So if "one of each thickness panel" refers to the steel (or aluminum) sheet to which the acoustic material will be affixed, that means you will have to apply (i.e.: glue) each sample material being tested to that metal sheet, then remove it after the test is complete... correct?
If so, what type of adhesive would you be able/willing to use (for anything that isn't peel & stick)? e.g.: 3M 90?
What is the approx. size (width x length) of that sheet?
Based on the size of looks like roughly 14" x 18"?
I have a couple materials (which you probably have not seen before) that I would like you to test, when you have time.
Thanks again for being so determined (aka: 'stubborn') on this project!
The total opening size is 14x17. There will be two test opening sizes, 11x11 and 12x15. This is so there is enough room to solidly clamp the material. It'll be much more clear why once I get the metal cut. I'll be sending the measurements over for that today.
The reason for the smaller 11x11 size is so that all available CLD's can have a fair 25% coverage test using a single, uncut sheet. The larger size will show why its important to use single uncut sheets whenever possible, and will show the disadvantages of some products based on their offered sizing.
