Comfortex foam. Does it work or is it just a ripoff?.

Comfortex foam. Does it work or is it just a ripoff?.

An incredibly vague question.

Looking over the website, the product appears to be typical foam based absorbers. Without test results on the actual products, it is hard to say. Raw material test data says little about the product(s) performance. If the raw product was good, why bother shaping the surface?

On a another serious note, do any of the detailed fire specs relate to construction? I couldn't tell from what I saw.

All foam products supplied upon leaving our factory conform to the requirements of Schedule 1, part 1, of the Furniture and Furnishings (Fire) (Safety) Regulations, S.I. 1324 of 1988 (amended 1989)(Amd 1993), and are also suitable for

applications requiring FMVSS302. The fatigue class is based on BS3379.

After seeing that fire at the Great White show I'm avoiding all foam in my studio. I don't care what they say about fire ratings, I'm not taking a chance.

Hi

We first made acoustic foam tiles last year, from two companies asking us to produce tiles to their specifications, since then we have had numerous enquiries for the same and similar products,

the foam grades we currently use are what are advised to us by one of the worlds largest foam manufacturers as being the industry standard acoustic foam grade,

acoustic performance data for our products has not yet been done as it is a new product range in our factory which we were testing the water with, and we have just had the go ahead to have the tiles tested for NRC and SAC data and also to develop products using other acoustic foam grades,

we chose the 25 kilo foam we use because it has much higher fire retardency than many other acoustic foam grades used in the UK

we are a large foam converter with a turnover running at over 10 million pounds per year, and although the acoustic treatments we have sold are a tiny part of our business, we have had nothing but positive responce from it so far , and so intend to develop the products further

please read the feedback we have had on the ebay sales of our tiles

Regards

Thanks for the info Mike. A suggestion if you have not already commsioned the acoustical testing of your product(s). Sheck how low the test facility will go in frequency. Low frequency absorption can be important for studio applications. Even if the testing is not able to be to E423 due to lack of diffusion, having numbers to present on you product(s) could help customers decide to your product, as you will "some test number" as opposed to nothing.

Good luck:
Andre

Folks,

The standards which Acoustic Foam CO. test to are not in conformance with the test requirements in the US.

So (as of right now) these products should be installed in any US projects.

The requirements for interior finishes in the US is that they be tested in accordance with "The Standard for Surface Burning (ASTM E84 or NFPA 255)"

If they are not tested in accordance with these standards - they are not approved for installation within buildings.

Sincerely,

Rod

Hi

We are a UK company and therefore cannot comment on any fire regulations around the world however the uk has one of the strictest foam fire regulations in the world in addition the grade we use has a higher fire retardency than most acoustic foams sold in the uk. it was a major decision in the reason we use this particular grade.

The foam meet the FMVSS302 fire retardency rating which was a test primeraly for the occupant compartments in motor vehicles however is often used for acoustic foam as it meets buildings plastics regulations, it also meets the much higher flammability rating of the UK furniture and furnishings fire safety regulations

We use only a specialist acoustic grade of foam for our acoustic foam products, the manufacturer is one of the worlds leading specialist foam makers, and is completley different from standard upholstery foams which have a totally different cell structure and resillience.

in addition not only does the foam meet the FMVSS302 fire retardency rating which was a test primeraly for the occupant compartments in motor vehicles however is often used for acoustic foam as it meets buildings plastics regulations, it also meets the much higher flammability rating of the UK furniture and furnishings fire safety regulations

the acoustic foam product we make are only a tiny part of our business which has a turnover of around 10 million pounds per year

We Chose this grade of acoustic foam as it returns the best overall absorption coefficient in the range. There are three main characteristics that can determine the absorption rate of a product. These are Density, Permeability and Hardness. Getting all three correct in a foam will give you the optimum efficiency. This Grade has a high level of all three desired characteristics



The acoustic foam grade we use is specifically formulated for acoustic applications by one of the UK's leading specialist foam manufacturers. it has been used for many years as the basic sound absorption foam due to its excellent performance for a wide range of applications. It may be used for acoustic enclosures, studio wall paneling, air handling units (AHU's), air conducting, cab linings and just about any other application where a controlled acoustic sound level is required.

CNC Profile Cut Grey Acoustic Foam, 25kg / m3 Density Foam which has a controlled permeability and open cell structure that gives optimum acoustic performance for a foam of this density.Hardness 125 to 155 Newton's

Below is the Foams Random Incidence Sound Absorption Coefficient for our cheapest tile

AFW45 45mm Wedge

125Hz 0.10
250Hz 0.29
500Hz 0.50
1 KHz 0.68
2 KHz 0.74
4KHz 0.98
NRC 0.55
