“Healthier” HVAC materials
Behealthy
| Posted in Green Products and Materials on
We are installing a new HVAC system. We are chemically sensitive and would like to use products that do not off-gas, if possible. Does anyone know of a healthier substitute for neoprene duct connectors, and standard duct tape or mastic? Also, we would like suggestions for a healthier duct insulation material. It is difficult to find such products. Green does not necessarily mean healthier, as we all know. Thanks!

J. Thurber,
I don't know whether mastic outgases anything dangerous -- I can't imagine it does, but if you are chemically sensitive, there is no predicting how you might react to mastic.
I will say this, however: there is no need to use neoprene duct connectors. I don't even know what they are. Here in New England, most systems have galvanized ductwork held together with sheet-metal screws, and sealed with mastic.
Martin, the furnace duct is vibration isolated from the rest of the ducting with a pliable duct connection made from I don't know what but not metal. Rubberized fabric.
One answer would be to not use ducts. Hydronic heat and window AC or a split air ductless system.
AJ,
I've seen plenty of residential duct systems without the vibration isolation system you describe, so if any homeowners want to omit it, they can.
I started to post eliminating the products and using the proper tape on the ducts or just not sealing the ducts.... but... way past my pay grade. I am thinking that I should add something to my agreements that says if you have now or at some later date a sensitivity to what I build for you, that you must name every exact item and product and method that you would want to not have be part of your build. And that you must post someone onsite 24/7 to verify such. There is no way I as a builder can ever guarantee that I could build a home that does not have some part of it that you may not be able to live with.
Best part of all the political yap of late is when they all preach... "take personal responsibility."
Jas, your best bet for your build is to find specialists to aid you. Also if you are in a good environment now, stay there. Everything new, out-gasses far more than aged items. Hey, another idea, build new but wait to move in for a few years. May not make sense but in a way it does.
