I need non-toxic windows that do not off-gas!
I seem to have exhausted all choices for windows. My house is framed and finished to the point where the windows have to be installed. I already got rid of the vinyl Fibrex windows. The house cannot be reframed w/o great expense so I need the sizes I need. I do not want vinyl. The all aluminum windows available from several companies do not make all the operating styles in the sizes needed. All of the wood windows have fungicides and pesticides and they won’t make them w/o them.
I think I may be down to an all fiberglass window. This is the SDS sheet for Ultrex. How does this sound? It seems to me that polyester resin with acrylic finish, compared to vinyl off-gasses less or none. Does anyone have Marvin Integrity all Ultrex windows (not Ultrex/wood)?
I need windows for a tiny house on wheels. It will be located in the Southern California desert. I do not want vinyl or Fibrex windows due to off-gassing of vinyl and plastic and I have no time or place to wait for them to off-gas. I do want good heat blocking more than heat retaining as the weather is mostly hot even though the nights can be cold in winter.
I am considering Marvin Ultimate aluminum clad wood exterior/wood interior, Integrity Ultrex exterior/Ultrex interior. (fiberglass), possibly Ultrex exterior/wood interior and possibly Jeld-wen all aluminum. I don’t know what other brands I might consider but these seem to have the best reviews overall.
I know the all-aluminum would be the least off-gassing but the least energy efficient as well. The aluminum clad wood/wood seems fairly toxic free other than the interior wood stain (or paint) that may off-gas quickly, or not?. I just don’t know if the all Ultrex fiberglass will off-gas especially if I have it on the interior as well (I’d rather not have to paint the interior and Integrity Ultrex/wood only has white prefinished).
I don’t know which brand to pick either! A difficult decision due to 3 factors: toxicity, U factor, SHGC, durability, and price! Help, please! Thanks!
