Asbestos in Simpson Forestone ceiling tiles vs
Simpson Pyrotec & Other Simpson acoustic ceiling tiles

Some Simpson brand ceiling tiles may contain asbestos:


The company said that their product did not contain asbestos. Litigation raised the asbestos question nevertheless.

In this article series we discuss how to recognize & handle ceiling tiles that may contain asbestos.

We describe the appearance, ingredients, years of manufacture, history, and producers of various types of ceiling tiles & coverings as an aid in determining whether or not a particular ceiling covering or tile is likely to contain asbestos.

InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website.

Simpson Forestone Woodfiber Acoustic Ceiling Tiles - no asbestos according to Simpson, Maybe asbestos according to lawsuit

Simpson Forestone Acoustic Ceiling Tile Information (C) M - IAPFrom multiple sources cited here we know that at most (about 3/4 of all) Simpson ceiling tiles contained asbestos.

Watch out: Troyce Wolf, a lead attorney for the defendants (Conwed and Simpson) in the Wagner mesothelioma lawsuit discussed in this article pointed out that

... Conwed and Simpson offered both asbestos-containing and non-asbestos-containing product lines. The tiles – one hazardous and one not – looked virtually identical.

“The two types of ceiling tiles were visually impossible to tell apart,” explained Troyce Wolf.

The attorneys for the plaintiffs (Wagner's survivors) searched product catalogs from both Simpson and Conwed, finding that roughly 75% of those ceiling tiles were Conwed's Lo-Tone asbestos-containing tiles. Conwed asbestos ceiling tiles were also purchased and re-sold by Simpson.

For these reasons it would be prudent to either treat any Simpson or Conwed ceiling tiles from the 1960s as PACM (Presumed Asbestos Containing Material) unless or until you have representative samples of such ceiling tiles tested by a certified asbestos test lab.

At the end of this article we include a link to a directory of certified asbestos labs.

Watch out: The Wood Conversion Company who produced Nu-Wood products later became Conwed Corporation. Court documents assert that some Conwed ceiling tiles contained asbestos. - (Wagner v. Bondex, Simpson, & Conwed, 2012)

Reader question: 4/15/14 Michael said:

I have a basement finished with acoustical ceiling tile. The previous owners left two boxes of the material. I took a picture of the box, but don't see how to post it. The box is printed with the following: Simpson Forestone Fissured Woodfiber Acoustical tile.

A large label is glued to the box with the following: Thickness: 9/16. Size 12 x 24. No PCS. Sq FT 56.

Large red F with a 1 in white in a reverse print. Then it says, Forestone Flame Resistant Finish. Center scored, flanged joint. Meets Class C of the requirements of Federal specification SS-A-118b. It also has a hand stamp that looks like a lot number of 30182.

Can you tell me if it contains asbestos? The Simpson lumber company is still in business. Would they know?

re-posting a subsequent post: Michael said:

Here is the photo of the Simpson Forestone acoustical tile packaging [photo above left].

[re-published; reader-links get blocked for malware security but I took a snapshot of your photo for use as needed here - Ed.]

Reply:

Let's try this: take another look at the box and give me

- any dates or date stamp codes on the material. If the lot number can be translated to mean made in 1982 that ought to be far enough past the use of asbestos in ceiling tile products as well as flooring to answer the asbestos question for this product -

The company can translate the lot number for you. (Let me know) The product label refers to wood products as the ingredients. We don't yet know where the flame resistance derives.

- the U.S. Patent number at the bottom of the label (I couldn't read it in your photo)

and we'll research the tile further.

Michael said:

The only thing stamped on the material itself is the patent number: 2,791,289. The patent (from 1952) covers how they create the textured look. The patent does mention a bunch of materials, but not asbestos. ...

I emailed Simpson's Public Affairs (its the only email contact on their website) and they responded that Forestone does not have any asbestos in it.

Helpful Michael, I'll add photos and information to our article as it should help others. Generally when a product says it's made from wood fibers it's not an asbestos item. That patent number is helpful - that's what I wanted to see.

Some photos of the surfaces of the tiles themselves would be helpful if that's convenient. You can use our email address at CONTACT found at page bottom.

Nice going.

We will add your photo to invite further comment. There a reader reports that Simpson (your ceiling tile is a Simpson Fonestone) informed him that their Fonestone line of ceiling tiles does not contain asbestos.

Simpson Fonestone ceiling tile asbestos question (C) InspectApedia.com NussbaumLet us know if you have further questions.

Watch out: at least some production associated with the Simpson brand has been found to involve asbestos. In June 2009 in the U.S. a Clayton County Missouri court, by jury trial, awarded damages to the family of a construction worker who died from mesothelioma after having worked for companies' asbestos-containing products thirty years previously.

Robert Wagner's death was considered to be the direct result of "... legal exposure to the asbestos contained in products manufactured and distributed by Conwed Corp., Simpson Timber Co., and Bondex International in the 1960s and 1970s

,...Mr. Wagner’s co-workers testified that he installed thousands upon thousands of ceiling tiles during his long career tenure. They confirmed never having seen a warning on product packaging about the asbestos hazard, and none wore maskes or breathing apparatus.

Product identification was central to the case. At the time of Mr. Wagner’s employment, Conwed and Simpson offered both asbestos-containing and non-asbestos-containing product lines. The tiles – one hazardous and one not – looked virtually identical.

“The two types of ceiling tiles were visually impossible to tell apart,” explained Troyce Wolf, WK partner and lead trial attorney. - retrieved 2018/06/17, original sources include: https://law.justia.com/cases/missouri/court-of-appeals/2012/wd72474.html and waterskrauspaul, a plaintiff's litigation law firm, https://www.waterskraus.com/ceiling-tile-installer-awarded-4-5m-in-asbestos-exposure-case/

Really? Because the attorneys in the case took what was described as a "shotgun approach" there were multiple defendants in this case and multiple products that contained or may have contained asbestos, fogging the view of the specific question about asbestos in Simpson/Conwed ceiling tiles.

Because Wagner worked around and used so many materials that contained asbestos, the plaintiffs relied on extensive witness testimony from Wagner's colleagues concerning which materials were used in the sites where he worked.

Some defendants confidentially settled with the plaintiffs before trial, some claims were dismissed and other defendants won on summary judgment.

Defendants included Bondex (joint compound containing asbestos), Conwed Corp. & Simpson Timber Co. (ceiling tile producers), and other defendants not identified in the press releases.


Question: Simpson Timber Co. of Seattle "Dectile Class III Vinyl coated decorative tiles

(June 15, 2015) Ron W. said:

My mom just passed away and her house has the Simpson Timber Co. of Seattle "Dectile Class III Vinyl coated decorative tiles" in it. We are selling the house and a potential buyer asked about the possibility of them containing asbestos. Do you know if this particular type did?

Reply:

Ron I don't know much about the Simpson Timber brand of ceiling tiles though from a timber company you'd think the product would be made from wood fibers.

However litigation that we discuss beginning at SIMPSON CEILING TILES indicates that some Simpson products contained asbestos, while the company has indicated to one of our readers that Simpson Fonestone ceiling tiles did not contain asbestos.

Cited in this court proceeding: www.courts.mo.gov/file.jsp?id=54841 - this is a wrongful death lawsuit involving Robert Wagner who in 2006 was diagnosed with mesothelioma. Excerpting:

In 2006, Robert Wagner was diagnosed with mesothelioma, a cancer that affects the pleural lining of the lungs. During the 1960s and 1970s, Wagner worked as a carpenter installing ceiling tile at project sites in the Kansas City area. Wagner worked primarily for two companies during that time period, Kansas City Natural Slate and United Acoustics.

In 2007, Wagner died from mesothelioma, and his wife and children ("Plaintiffs") brought this wrongful death action. Plaintiffs claimed that Wagner's mesothelioma resulted from exposure to the asbestos-containing products manufactured by Bondex and Simpson Timber ("Defendants").

Bondex manufactured a joint compound that was commonly used on construction sites during the installation of drywall. From 1961 to 1977, Bondex joint compound contained asbestos.

Simpson Timber manufactured ceiling tiles. During the 1960s, Simpson Timber manufactured both asbestos-containing ceiling tile and non-asbestos-containing ceiling tile. Simpson Timber also purchased and resold ceiling tile from Conwed that contained asbestos. 

On June 3 2009, the jury returned a verdict in favor of Plaintiffs in the amount of $4.5 million. The jury apportioned fault as follows: 20% to Bondex, 35% to Simpson Timber, and 45% to Conwed Corporation. Following the verdict each defendant filed a motion to delay entry of the judgment.

On July 7 2009 the trial court entered its Judgement and Order reducing the judgement amounts. Defendants then filed motions for judgement notwithstanding the verdict "JNOV". All JNOV motions were denied.

Following the trial court judgement the defendant appealed the judgement to the Court of Appeals of Missouri, Western District, Division Four.

The appeal was dismissed because the trial court did not address the remaining John Doe defendants named in the suit.

Plaintiffs also filed a motion to dismiss and for entry of an amended judgment arguing that the settlement process between Plaintiffs and the THAN Bankruptcy Trust was deemed non-existent by a federal bankruptcy court.

On 24 May 2010 the trial court entered its final judgment that reduced the settlement amounts by $1,425,000.

Both Defendants (Bondex and Simpson Timber) and Plaintiffs appealed that judgment. (Defendants claimed that plaintiffs failed to demonstrate causation.) A key point of law argued in the 2012 appeals court ruling was from Poloski, "IN order to prove causation a plaintiff must prove that 'but for' the breach of duty, the event would not have occurred. (Supported also in Calahan).

In June 2012, the appeals court case of Wagner v. Bondex and Simpson Timber and Conwwed Corporation was decided, affirming the lower court's judgment.

It is important for both you and a buyer to avoid inappropriate (and thus expensive) panic about asbestos. Generally asbestos-containing materials such as ceiling tiles are safest left alone and in-place unless the material is damaged, falling down, shedding, leaving debris that can be tracked through a home or otherwise made airborne.

It's ok to paint over, encapsulate, seal, or cover-over such materials if occupants prefer. Unnecessary removal is actually more likely to be hazardous than leaving the material alone.

Reader question: (Mar 6, 2014) Mike said:

back in 1996, A friend of mine picked up a truck load of 2x4' ceiling tiles that were being removed from a small grocery store for total renovation (new owners I believe).

Anyway we finished his basement over several days, and never even thought that they could be asbestos containing.

Unfortunately, there is no way for me to test as he no longer lives in that house. They look like your common "department store/hospital" 2x4 tile, fairly heavy, could be broken easily (crumble), grey/brown back color with white face, and they did not burn (we tried!!) They almost seemed to be made of plaster or clay if I remember correctly.

As this was 1996, Its likely the tiles were at least 10-20 years old, which is worrying to me. I found a picture of the room where they were installed, not very clear as it was taken 10 years ago, but I could send it if you like.

They had a design texture very similar to this: i.imgur.com/m0wS9h6.jpg

Follow up picture to previous comment, this is the only known picture i was able to find of the tiles in question. I wish I could do better. imgur.com/NpnfGtQ

Reply:

Mike we can't say from just the acoustic ceiling tile pattern if the product contained asbestos or not; and indeed even some older ceiling tiles have been tested and found not to contain asbestos.

If the second photo link you sent was of the room you describe I can't add a thing other than that we're apparently looking at a suspended ceiling from 2004 (10 years ago) or older.

Reader follow-up:

Thank you for the reply. Yes, 10 year old picture of a 20 year old renovation, I wish I would have taken some close up pictures when I had the chance. The tiles most certainly were made sometime during the 1970's or 80's.

Was it common for this style drop ceiling tiles in commercial settings to contain asbestos during that time?

Reply:

Ah - so if we're talking about ceiling tiles from the 1970's or early 80's asbestos was a possibility - but did not appear in all brands and products of ceiling tiles

Excerpt: Simpson Pyrotect acoustical materials have been retested by Underwriters' Laboratories, Inc. and again found to have fire hazard protection ratings equal to those of mineral tile.

This factor, coupled with the low cost of Pyrotect, puts maximum interior finish fire protection within the reach of everyone.

Look for Simpson Pyrotect in the 1965 Underwriters' Building Materials List and for the UL label on every carton of Pyrotect.

The Simpson Pyrotect ceiling tile shown in your photo above, produced by the Simpson Timber Company (founded 1890) was described in Oregon State University's index of Forest Industry Products in 1963 in this article:

giving us an era-date of the early 1960's for the product - consistent with the trademark filing.

The actual article on Simpson's Pyrotcect tile is not (yet) found online - that'd be a perfect place to confirm the presence or absence of asbestos in the product description as may be some patent disclosures.

According to the trademark filing, this was a wood product - asbestos isn't cited nor were the fire resistive properties explained: I am researching further.

Really? It's helpful to note that fire resistance in ceiling tiles and ceiling panels was achieved in some products without use of asbestos, such as use of gypsum board panels and use of mineral fibers or slag wool or mineral wool or fiberglass.

Watch out: however as you will note in Simpson's patent below, the use of fiberglass did not rule out combination with asbestos.

On 2023-02-18 by InspectApedia Editor - damaged and sagging ceiling tiles need inspection to determine leak source

@Dave Simmonds,

Perfectly acceptable resolution IF you have made sure to address the leak that caused them to fall. Did you find the source of the leak, fix it, and also be sure that all wet materials were dry or replaced - drywall, insulation, wood?

The last thing you want to do is to enclose the space where the leak occurred without addressing its cause and fixing any damage. That would just be a potential breeding ground for mold let alone another leak.

Simpson said their ceiling tiles did not contain asbestos but litigation came up with a different answer as we describe above on this page.

@bhawk,

You may want to remove the sprayed, moldy tiles so as not to leave a mold reservoir in the building.

I didn't find indications that anything but wood-fibre or plant fiber was used in these particular tiles but for an unequivocal answer to the asbestos question it'd be best to have a sample tested.

If you decide to do that, please keep us informed as that'd be helpful to other readers.

MW

In the article above in answer to the question: Do Simpson Fonestone ceiling tiles contain asbestos, we include this key remark excerpted from litigation on the topic:

Product identification was central to the case. At the time of Mr. Wagner’s employment, Conwed and Simpson offered both asbestos-containing and non-asbestos-containing product lines. The tiles – one hazardous and one not – looked virtually identical.

However, for a box of intact ceiling tiles, even if these are ones that contain asbestos, the airborne asbestos hazard that you might face by having to move the box of Simpson Fonestone tiles (that may contain asbestos) is almost certainly below the limits of detection. Just open a plastic garbage bag, set the box inside, close the bag and put it with your trash.

I have this box of tiles in my crawlspace that my basement has installed in ceiling. Here is a picture of the box itself.

Geoff,

I don't have specific data on that exact Simpson ceiling tile. However as we explain in the article above, given that about 3/4 of the ceiling tiles sold by Simpson contained asbestos you should either treat yours as presumed to contain asbestos or you should have a sample tested by a certified asbestos test lab.
