Hello, We are looking at a composite wood being manufactured in Singapore for use on exterior decking using melamine-urea-formaldehyde as the resin. This sounds like it is valid to do in terms of this credit as this is not for the interior of the building. It would be in Phuket Thailand, which is certainly a hot and humid climate so issues of off gassing could be a concern. Should there be a concern for doing this as well as putting IEQ credit 3.2 in jeopardy when it comes to air testing (if the VOC gasses leak into the villa/home)? Any feedback is appreciated. John

John, as this is outside, it doesn't fall under the requirements of this credit.It's always a good idea to use low-emitting materials, though, so you could try to get emissions data for the decking material, and if it is low, this may reduce concerns about indoor air quality effects. I would think, though, that the effects would be minimal, particularly if the windows and doors are closed for testing.
