If I painted these panels and put them up in a children’s play area would it muffle an echo with cement walls?

Asked by Sassy August 29, 2020

Answers

Hello Sassy, Foamular Insulation may be perceived as a soft, porous material which, if installed on the interior surfaces of a room, may absorb some sound energy, thereby reducing reflective sound and shortening reverberation time. However, Foamular Insulation is a combustible material and is not recommended for exposed use in interior spaces; once covered with a thermal barrier such as ½” gypsum board, the sound absorption properties of Foamular Insulation become irrelevant. Thank you for your inquiry!

Can it be used for soundproofing

These worked perfectly for my project. I was looking for solid foam board to make a floating raft for my hydroponics system. It was easy to cut and floats very well.

Great for insulating window air conditioners
I came across this material after doing some research on YouTube to better improve insulation around the window A/C units. My summer electric bills were three, almost four times what they were in the fall and winter months because of the brutal heat. After evaluating several Home Depot products, this seemed to be the most economical since I would not need to replace them every summer when its time to put the A/C back in the windows. I was able to get by with one sheet for three windows which made me extremely happy and better yet, the next day with 92F outside, my home remained a cool mid 60s temperature inside. It did a fantastic job of keeping the heat out and keeping the cold air in. They were also very easy to cut to the exact dimensions I needed. A ruler, a pencil and a carpenters knife. I made the portions 1/4 of an inch wider than I needed and squeeze in the small cut out of foamular to make an airtight fit. I did not even need tape to hold them in place. The tension between the A/C and the window frame held them in place. When the fall arrives and its time to remove the A/C units, I will label the cutouts to match them with the A/C so that next year I will know how to install them correctly. I love that they resist moisture, mold, and mildew. They are very economical and they kept my home much cooler. I set my A/C unit thermostats at 68 and they cycle on and off when needed. Mostly off at night because the foamular maintains the coolness in the evenings. Great product.

I love working with these panels they are very smooth easy to cut. I only wish you would sell these in larger sizes. They are easy to paint and I used them for many art projects for retail display in stores and parties. I use this product for specialty custom art designs.

Excellent for DnD terrain crafting. Its sturdy, doenst fall apart when managed. Reacts very well to glue and easy to cut. The price is pretty good. The photo shows an obelisk made out of Foamular. I had to stick to pieces together since Home Depot didnt had a thicker board, then cut the sculpture and then applied the different layers of paint to create that look.

I used the 1" x 24" x 24"" Foamular" Panel by Owens Corning That I purchased at Home Depot to create a pet door for a sliding glass patio door. I cut the panel into 6" sections. They fit perfectly into the door seam with a snug fit. I locked one side of the glass door in a fixed position & carved out a small section where the lock nests into. It works perfect.
