Hi peeps,

I's like to build some absorbers for my rooms.
Anybody knows where to get fiberglass panels in Sg?
common brand such as owen cornings, etc.
How big are they normally and what is the price?

Thanks

Comes in 4x2 feet, 25-50mm thickness per sheet. One bundle has about 4-5 sheets. Can't buy loose pieces. One bundle costs bout 30-40.

Owen Cornings doesn't have a stockist in SG

Approach Roxul Singapore.
Singapore | Rockwool Asia

For audio, the 60-80 kg/m3 rockwool works well

thanks dominion.
i'll need quite a few, so bundle buy is better actually
btw anybody know someone who i can engage with simple woodworking?
not looking costly pros here, just simple cutting and sticking job hahaa.

There is a shop in Sim Lim Tower basement selling wall mounted foams.

What project you have in mind?

[consilio]

I want to treat the back, side and ceiling of my room.
since tay in a rented house, i can drill or nail anything.
i'm thinking of making scaffolding along the edge of the room and put attach the panels on the scaffolding.
it's a long shot and super ambitious but i'm determined.
ethan winer got me poisoned with importance of room treatment.
the scaffolding can be made out of steel which will be very expensive.
or cheaper alternative with woods.
i'm moving soon, so i'm gathering info on material and cost.
don't want to engage a pro coz i also want to take part in building it.
ideally, someone with DIY enthusiasm with tools who don't mind working with me.
i will cover all material cost.

hahahaha i'm blabbering.

why need to use steel scaffolding? No reason to what, unless you're going to abuse the bass traps.

if you're talking about bass/broadband traps, you can do most of it yourself. Ban heng long supplies the timber and cuts to size you want. Quite cheap for the cutting service also. You can google their number, call them up and ask for quotation with the wood dimensions you want. Use plywood. MDF is too dense and chips too easily.





Some things i would do differently if i were to do this project again:
1) Glue and clamp the wood frames instead of using nails.

2) Use some sort of hard plastic/object to frame the rockwool edges to get a crisp, sharp look. My bass traps look like giant pillows because i didn't do that. All i did was overlay the fabric directly on top of the rockwool, so the end result doesn't look that great.

3) Don't go overboard on the amount of bass traps. I have studied Ethan's material, he's an advocate of putting bass traps everywhere, especially in a small room. If you're doing mixing/mastering, that sort of dead environment can be desirable. But if you're listening for pleasure, it can get too dead.

4) How big is the room? Can you afford to put up 4" bass traps in the corners?

wow, thanks for sharing ur experience and tips.
i'm not going with steel of course, it will super expensive.
I already have 3 wooden and 4 arranged 3D diffusors.
if needed, i'll rearrange the 3D blocks
I'm gonna mix it up so that the room won't be too dead.
they key sentence that i'm going is "to make the walls dissapear"
ethan did mention that some amount of "liveliness" is desirebale, all depends on listener need/preference.
this i will have to test and try, no way getting around it.

btw, the config i'm planning:
ceiling & corner: just basic rockwool panels



back & sides: wood panel embrane trap



I'll try to persuade the owner to allow me to ditch the cupboard so that i can have as much as space on the back.
the distance of rockwool and wall is crucial according to ethan

Are you using 1D/2D diffusors? How are they being placed in your room now? Not bad man, you have an understanding owner who lets you do such stuff in the house, that's quite fortunate

Yes, you want as much gap between the rockwool and wall as possible, for increased bass trapping efficiency. Best if you can go with 4" or thicker everywhere. If you go with 2"/1" panels, it's not very ideal because it can throw off the spectral balance e.g. absorbing too much highs compared to the rest of the frequency spectrum, and the frequency response will sound weird.

All the best with the project
