Hello! I chose the sarg fabric, almost 4 times cheaper.
Anyway, I was thinking of painting the horizontal beams at the top and bottom since any gaps between the fabric and beam will be visible there. The vertical beams are covered by the columns. Does this paint work for that?
I bought real paint instead. The fabric will arrive this week, and now I will paint some of the beams so that any gaps between the fabric and beams are not visible. Then, when the fabric arrives, it will be time for the stone wool.
Attaching the fabric was a breeze! However, I've encountered a frustrating problem!
The Gobos are now filled with rock wool. They are 39.5 cm deep, with the rock wool being 39 cm in total. Yet, it bulges out like a balloon on both sides. It doesn't matter if it bulges out at the back since it won't be visible, but the front is worse. What should I do? Should I "shave" a bit off the front so it's in line with the absorber? How can I prevent the rock wool from pushing out the fabric at the front? I have an idea about using angle brackets that I attach inside the frame to secure the edges of the rock wool, then I thread a string in a zigzag manner between them, like lacing a shoe. Then the fabric would be on the outside of this. Would that work? Or how do you usually do it?
Then one more small question, the back wall is covered with rock wool from floor to ceiling. 39.5 cm thick plus 21.5 cm air. The right wall faces the outside. Should I leave a small gap between the rock wool and the wall to prevent moisture buildup? We are talking about a 2.5 m high and 39.5 cm wide section of the outer wall that will be covered with rock wool.
I'm in full swing building and made some independent decisions. Among other things, I reorganized the stone wool so now it is 2.5 cm too short, which in practice became about 0.5 cm. The question about the distance between the outer wall and the stone wool is still there.
I'm thinking I'll take 3-inch-1 planks and saw and attach them horizontally to the wall. That is, 39.5 cm long pieces attached to the vertical stud with angle brackets. This creates small channels behind the stone wool and the wall. However, the channels are closed at one end by the stud. Does that matter? Does the air need to circulate for it to work? Or is it enough that there is air between the stone wool and the stud?
Feels like I'm talking to myself here now, but I solved it! If it was a problem, I don't know, but it's solved now. I cut wide grooves in the 3-by-1 planks, so now the air can circulate between the rockwool and the wall without any problem. I have no more questions for the moment!
It will work just fine. Actually, the insulation doesn't need to go all the way in as it is the 1/4 wavelength that is absorbed.
Great! Thanks for the answer! May I just ask, how can I keep the rock wool in place so it doesn't push out the fabric? I managed to reduce the thickness of the wool but still, it bulges in some places. Does it work to attach angle brackets on the inside of the frame and stretch cords in a zigzag pattern? Or how do you usually do it?
