Diagnose & cure odors offgassing from fiberglass, plastic, or vinyl window parts:

Field reports discussing odor complaints reportd from fiberglass, vinyl and plastic windows & window parts including Marvin Integrity window sash frames.

This article series discusses common odor sources, including indoor plastic odors or chemical smells observed at some installations of vinyl exterior building siding or in other plastic or vinyl building products such as windows and trim. We describe common sources of plastic or vinyl type indoor odors and we provide a checklist that can help pinpoint the source of such odors by noting information about the building construction, building materials, HVAC systems, weather, sunlight, temperature, time of day, wind direction, and other clues. We provide links to articles detailing possible health effects of exposure to indoor VOCs and plastic odors and smells.

Reader Question: Odor complaint and offgassing at Marvin Integrity Windows

Marvin Integrity Window offgassing odor question (C) InspectApedia.com DMHere are some photos of the area mentioned [in prior web page comments or email - Ed.]. The smell from inside the carve out area gets stronger when the sun comes out. Room stinks up when windows closed. I was thinking of painting that area with the drill holes.

Windows combine fiberglass with an additional top coating described by the manufacturer, Marvin Windows. But perhaps the surrounding window frame is of different composition, even entirely vinyl. That's a question to ask Marvin Windows.

Your observations suggest an odor coming from the window frame, whose constituents we don't know. Also, suggested by your observation that the offgassing odor from these Marving Integrity windows is strongest at drilled screw openings, I speculate that offgassing from exposed plastic, PVC, fiberglass or any material that is on the interior of a closed frame is likely to be extremely slow.

Other window odor complaints are sometimes traced to the sealants used to install the windows. If you can find out what sealants were used on your windows and can obtain some of that product and give it a cautious sniff that might also be diagnostic.

Marvin's Ultrex™ is thermoset, vinyl (thermoplastic) that may off-gas VOC's (see below). Perhaps the frame construction uses more of this material. A Marvin page http://www.marvin.com/integrity?brandsetting=integrity describing Marvin's Ultrex fiberglass product features.

Informal (not scholarly) Research on Discussions of Offgassing from Marvin Integrity Windows

Researching Marvin "Fiberglass Window" Odors, using this phrase "odors from marvin integrity windows", finds other odor complaints and references to use of a protective coating referred to as an acrylic capstock that some consumers opine was the source of "acrylic" odor complaints. The fact that odor complaints appear on several web pages (though of course none may be technically authoritative), is both disappointing and is suggestive that there probably are real complaints about odors and offgassing from these prodcuts

Contact Information for Marvin Windows & Marvin Window Warranty Information

Have you contacted Marvin to ask their advice about this odor and to ask for pertinent window component or coating MSDS documents. If not I'd do so.

Reader follow-up:

Marvin Integrity Window offgassing odor question (C) InspectApedia.com DM Thanks for sending those links. I found those too during the frustrating months of trying to learn about the window smell I was experiencing. I wish I had known before before purchasing. I reached out to the "some_guy" reddit post, as you saw he had same concern with the pregnant wife/baby.

He said it took a couple of months for his windows to dissipate. I am hoping that's the case here as well but mine have been going on 2 1/2 months.

I did reach out to the window installer who connected to me to the local Marvin representative. He came out a couple of weeks ago and also noticed the smell. He had never experienced the issue but did not disagree about the smell or where it was coming from.

Following that visit, I got a lame letter from Marvin. It's attached. In response, I wrote a strong letter back to the Marvin reps and the window installer earlier this week. No response yet.

I did not ask for documentation on the window component or coating MSDS. Perhaps I will if don't hear back from them.

I am thinking these drill holes in the fiberglass in the carved-out latch area are the problem. Was thinking of sealing the holes up with super glue or something, putting some aluminum foil down, and then putting the latch back without the screws (they really are not necessary). ...

Moderator reply:

OPINION: If closing off those drilled openings seems to stop the odor problem (I gave a theory on this earlier) then your plan sounds reasonable. An alternative that works for some cases is to use a combination of ventilation and heat to try to speed the offgassing. And sealing off-gassing materials will most-likely slow down the off-gassing process and thus extend it over a longer period.

Quotes below are from a letter provided by this reader:

Thank you for your questions on your new Integrity by Marvin product.

Integrity products, like all other new products, do have a "new" smell associated with the product. Windows are not generally considered a threat to indoor air quality. The fiberglass material used to produce Integrity product has no volatile organic compounds (VOC) or vapor/fumes being off-gassed that would be considered dangerous or hazardous.

Everything new has a new smell associated with the product. The size of a home, or room, size or number of windows/doors, home ventilation, and room environment tend to influence the detections of building material odors such as expanding foam insulation, sealants and caulking. Over time, as with all new products associated with inherent smells dissipate. [sic]

Please be assured that your new windows will not harm your family. Please contact me if you have additional questions or concerns.

Sincerely,

Reader Question: vinyl replacement windows smell musty at their seams, especially in sunlight

Last October (2010) we had replacement windows put in. They are stained inside and vinyl outside. If you put your nose to the the seam of the molding on the sides of the windows you can smell a musty/moldy(?) smell. We had no problem prior to this.

The odd thing is that when the sun is hitting the two affected windows (South side of the house) you can sometimes smell it as soon as you walk into the room. When the sun is not as strong (winter/cloudy, etc.) you have to put your nose to the seam to smell it. I have taken off the outlet covers and smelled there figuring if there were mold in the wall I would smell it - just dusty smell like all other house outlets (house built in 62). There are no other signs of mold.

Since the smell strengthens and alleviates (I don't think mold would do that?), It is the south side of the house, and that it started right after the new windows were put in I thought it was associated with that. Have you heard of this with windows. I also suspected the caulk? We removed the molding on one window, caulked, and replaced it and that did cut down on some of the smell.

The other weird thing is that in the summer our room smells worse than my child's and in the winter his smell worse than ours (different ways the sun is shining?). I appreciate any help you can give me. I am wondering if my scenario seems correct and how long until you think the smell will go away. I don't like my son breathing this. - Mel 12/30/12

Mel,

Indeed there is ample empirical evidence (field reports) that some formulations of vinyl building products emit a plastic odor (possibly vinyl chloride) especially when heated, for example by sunlight.

In our experience the odors usually diminish over time but to those who are sensitive to plastic smells, the odors may not completely disappear.

Watch out: We don't know the chemical composition of the odors you describe, but to be on the safe side, I would NOT have a child sleeping in a room with noticeable plastic odors - wait for them to dissipate. Take a look at the health and exposure information described in the articles beginning at VINYL CHLORIDE HEALTH INFO (article links listed at the "More Reading" links at the bottom of this article )

.For details see PLASTIC or VINYL ODOR EXPOSURE - we have moved the plastic odor or burned plastic exposure discussion there.

That article discusses PVC exposure and also more general
PLASTIC, BURNED ODOR EXPOSURE HAZARDS

Watch out: Vinyl chloride might be present in gas form as a colorless, flammable gas with a faintly sweet odor at levels of about 3000 ppm (the odor detection threshold). We provide the US EPA health report on vinyl chloride
at VINYL CHLORIDE HEALTH INFO.
