Hi everyone,

This post is to warn you not to buy acoustic panels from GIK Acoustics, and I'll explain why.

Three years ago, I decided to make an acoustic treatment in my living room (that I use for Hi-Fi listening and Home Theater) and, as I don’t want to make them by myself (even if I could, there is no technology inside an acoustic panel), I opted for panels from GIK Acoustics and Addictive Sound, two leading companies in this field.

From GIK Acoustics I purchased six “Tri-Trap” (triangular bass traps to be placed in the corners of the room) and four “244” panels for the side walls (for the first reflections), while I opted for six PREMIUM panels from Addictive Sound for the front wall (the one behind the main speakers).

A few days ago I had the idea of opening a GIK Acoustics bass trap (I wanted to change the color of the canvas to match the new color of the walls), I opened one of their triangular Tri-Trap, and I discovered two things that made me deeply disappointed:

a) Between the external canvas and the inner rock wool they do not put any layer of "non-woven fabric" as all other manufacturers do, with the result that, when I clean the panels with the vacuum cleaner, the small rock wool fibers are attracted towards the internal surface of the covering fabric and can, sooner or later, come out. Although rock wool fibers are said to be non-carcinogenic, they are still harmful to your health and can irritate the lungs if inhaled.

b) On their website they declare that they use rock wool with “ECOSE” technology (which is brownish in colour) while instead they use the more common “Isover” (which is yellow in color). This was also confirmed to me by one of their employees, Mr. Lukas Rimback (I have the emails) who replied me via email for explanations and confirmed that they no longer use ECOSE rock wool (which should be less harmful to health as it is free of formaldehyde and other rubbish and be made with recycled materials), but they still declare on their website to be used.

Furthermore, since the beginning, GIK Acoustics panels have always smelled a lot, even if I clean them regularly with the vacuum cleaner, I can't tell you if it's the glue they use or the wood, the fact is that if I don't air the living room regularly an acrid odor is created that gives you a headache and makes you sneeze. This problem (the smell) however is not present with Addictive Sound panels.

Needless to say, I am really very disappointed, I contacted them to complain to them and they replied that there is no European regulation on how to build acoustic panels and therefore they are right and that's fine, at my side I will never buy again panels and bass traps from GIK Acoustics, they invest a lot of money in advertising, on social media, and nothing for Customer satisfaction and the health of their Customers.

In conclusion: GIK Acoustics uses a standard rock wool different from the "ecological" one declared on their website and they do not put any protective cloth to retain the rock wool particles, I attach two photos below. feel free to draw your own conclusions.

Can I ask if you have had any dialog with the company regarding your concerns?
Yes I had, and they tell me that everything is fine in this way, as I wrote above.
So for them is fine to cheat Clients declaring that they use ECOSE rockwool and instead put in their panels the more common Isover. Very bad.

Apologies- missed that.
 
So your complaint is not how the panels perform, it's how they smell?

I could have a problem with that. As for the health issue and using a vacuum cleaner, don't use one, use a sticky lent roller. ALL airborne
fiberglass is bad and rockwool is no different than any material that can lodge in your lungs and your body can't absorb and dispense of.

DUST is worse by far because it's looked over. Smell is a tough one. If it stinks go into a small claims court and let the judge give it a
sniff. It's NOT reasonable to have ANY smell that lingers. You should have a good case for that. The rockwool I don't think so. It's to
easy to clean it in other ways. The way you're pulling the Rockwool fiber can be mitigated by simply venting the hose. There is ZERO
threat to your health.

Is the smell bio or chemical? I'm sure you can seal the odor without affecting the performance. Spray wax (Pledge) should work fine.
Bio smells can be mitigated with enzymes very effectively. Oil can be removed from soil vs remediation with certain products. They
do it all the time with leaking oil and fuel tanks. Bugs actually eat the stuff and then die, the only problem is treating the bugs dying
and they use enzymes to treat that when residential areas are involved. I have 1/2 gallon and it smells like vanilla.

It's used in refineries all the time with bugs that EAT the thick oil residue in pipes and then die. The bugs are grown in carbon storage
tanks. If the bugs die (the wrong carbon mix) they produce H2S, it's explosive when off-gassing and deadly to breathe at any concentration.

Regards

No, my complaint is about the fact they declare a thing (to use "ecological" rockwool) but do another one (use a cheaper standard Isover one), and don't put any "non woven fabric" layer under the outer canvas to avoid the rockwool particles can exit the panel.

It's not a bio smell, not smell given by dust, but is a chemical one, if you carefully read my post you will see that I wrote about glue used to glue the wooden parts or the wood itself. My house is smoke-free and very clean, and they smelled since the first day I removed them form their shipping cardboard box.
 
@Raticosa
Out of curiosity did you also opened the panels from Addictive Sound? I'm curious to know if everything is OK there.
Could it be not putting any layer of "non-woven fabric" is a standard "industry practice" around our part of the world? (I'm from Italy too)
 
The interior of my many GIK panels is white.

I notice no unpleasant odors.

I don't vacuum the surface of the panels but do vacuum other surfaces in the room regularly.

Hmm.
 
No smell with my panels, and I have 19 of them in a 4.4m x 3.4m x 2.4m room, there may have been an odour when new 4 years ago but I can’t remember if this was an issue or not at the time. My panels get vacuumed on a low setting quite regularly by my mother, she’s one of those “clean freaks” (luv ya mom but please put the duster down and step away from the cleaning products) and never commented on fibres coming through the outer fabric, I’d notice them as my 4 tri traps are black and show up the slightest spider web etc.

I’m pretty sure there is a layer of permeable material covering the insulation material on my GIK panels, perhaps they are built differently in the UK

That's a bummer you're so unhappy with the panels. My experience has been different. I own 10 total panels from GIK. None smell, I feel they perform quite well for the price, and they all improved the acoustics in the rooms I've use them in as expected.

For keeping them clean, I would never vacuum them, assuming they would definitely pull fibers thru the fabric. I have 5 other panels from ATS Acoustics that are the same (no extra layer of insulation blocking fabric) and I have no problems with them either. I've always just lint-roll them and it works great.

I'll be buying a whole bunch more GIK panels later this year when I finish my soundproof listening room.

You said I can't TELL you if it's the glue or the wood.

So it's one or the other. Some woods like apitong have a nasty smell and are harder than the hubs of hell. If it's the glue holding the wood it HAS to harden
over a period of time.

The Rockwool is not a problem, IF you treat it like it is. Vacuuming will not cause a problem, that is the reason in environmental cleanups they use a vacuum
and filter the exhaust. I worked as an HD mechanic for an Environmental company for 19 years of my 45+ year total.

As I said IF YOU READ Dust would pose a greater risk to your health than the Rockwool. It would have to be airborne not sitting in the corners or even open
air, unless you physically scraped the stuff and then BLOW the particles.

I suggested sealing the rockwool with a liquid wax like Pledge and spray at least one panel or whatever it is with Pledge and see if the small settles down.

The fact that something continued to smell is a concern as I said. It is OFF-GASSING. Things that can cause that are heat and movement.

A pile of shit usually doesn't smell unless you step in it

If the smell dosn't go away drag the company into small claims. I hope they have a court system for that where you live?
 
These are velocity absorbers which means they only work if air goes through them. Using a non-porous fabric would turn them into more of a reflector and reduce their effectiveness.
 
Posts like this flaming a vendor always make me question both the vendor and the OP. Has the OP cut open one of the "PREMIUM" panels from Addictive Sound?

FWIW, I purchase a number of absorbers and diffusers from GIK. They had no odor at all, and have helped some with reverberation issues I have in a room with a concrete floor and big windows. I'm sure there are better products out there, but they have worked out fine for me.
 
Looks like quality PLY. maybe BB?
If the same quality ply was used for the entire frame then the wood likely has no smell.
if its cheap chinese wood it could smell..

I'm very interested if you determine the source of the smell. strange glue to hold parts together?

Rockwool comfort board 80, rock board 60 and safe and sound. used all of these and no smell

no batting under the top fabric is inexcusable!
 
Honestly this type of absorber is pretty easy to make yourself, avoid any recriminations or disappointment and simply wrap fabric around pieces of rockwool at home. Be sure to wear gloves and a mask.
 
I have four GIK panels and they don't smell. I also made some simple unframed panels - in other words just rockwool stuffed inside jersey (t-shirt material) pillowcases - and the rock wool I got from my local home/hardware store doesn't smell either.

I wonder if long-term slightly high humidity could create a mildew smell or something? The insulation made from recycled denim contains an anti-fungal agent or mold inhibitor for this reason I believe, but I don't think rock wool contains any such additive.

Rockwool is not affected by humidity. According to them, from Why does moisture repellence matter?:
Moisture repellence means it is engineered to prevent water from penetrating the surface, while non-hygroscopic means it will not attract or absorb moisture
