Anyone discover they have or know about having allergic reactions to the blown in insulation they use around here? I noticed one house of mine has blown in insulation in the attic and I have developed massive allergies in the house. My other house has batting insulation and I don't have any issues. I can go from one house to the other and go from allergy attack to cleared out and back the other way. The only real difference between the 2 houses is the type of insulation. They are both less than 10 years old. What are they using for blown attic insulation around here and is anyone aware of any issues? Has there been any local issues brought to light? Has there been any litigation against local builders here?

Though I'm not discounting your diagnosis I'd think a 10 year old house could have a LOT more allergy related issues like mold, pets (dander lingers for a long time), etc.

Easiest thing to do is to bottle up some of the blown insulation and take it to the other house, or even outdoors somewhere, then uncap the bottle and see what happens. Simple process of elimination against the insulation.

I have owned both these houses from the get go. No pets or anything else that would cause this issue. Tests confirm no mold. Both houses are less than 10 years old, not ten years old.

Blown-in attic insulation is typically cellulose (paper) that has been treated with a chemical fire retardant. This type of insulation has been used for 50+ years and in literally millions of houses. I guess it is possible to be allergic to it (like anything else) but I would be really surprised if this is your specific problem, especially if you are not going up in the attic and rolling around in the stuff. Surely there is something else different about the 2 houses than just attic insulation.

See an allergist for skin testing to find out what allergies you have.

Default May be fibreglass, or even rock wool

The other common type of insulation that is blown into attic spaces is shredded fibreglass. The same material as used in fibregalss batt insulation, but smaller pieces that can be blown thru a hose by a powerful fan.

Rock wool insulation is possible, but much less likely. As the name implies, it is made from melted rock that is drawn into a mass of intertwined strands very similar to fibreglass.

Did you get the duct work checked for mold and other substances?

It could be any number of things making you sick, I'm know there are many more differences between the two homes than just the type of attic insulation.

That all checks out. I have read a lot about different types of insulation affecting people differently. Other than the insulation the only thing I can think of is I could be allergic to the people occupying my other house. Maybe I am allergic to them and I shouldn't show up there anymore, which wouldn't go over so well as they are relatives. So far it doesn't sound like anyone else is aware of any issues with houses in this area.
