A little while back, I heard something about a certain type of insulation that contained high levels of asbestos. We have a cat litter type insulation in our ceiling. We have a forced air type system in our home and when we have removed the duct covers, some insulation spilled out. I am just wondering if anyone knows what type of insulation it was that contained these high levels of asbestos. I also wanted to know how you go about having your insulation tested for this. We bought our home 2 years ago and it was built in 1963. I have no idea when the insulation was installed or who manufactured it. I am a bit concerned because of our forced air type system. Any help is greatly appreciated!

There are several types of "loose" insulation that do not contain asbestos. Yours sounds like "vermiculite" which was popular in that time period. You have the right idea.......get it checked. Usually your village township office or planning and zoning can direct you to a testing facility. Good Luck.

We bought our home 2 years ago. Obviously, there is some sort of hole in our ductwork that allows this insulation to get into it. Based off of what I have heard more recently, will we have trouble getting someone in to repair the ductwork? I am afraid it will be hard to find someone who will work in a hazardous environment.

2 thoughts:
1) After you cleaned up the loose insulation from removing the duct covers, has any more shown up in the same places? If not, you may not have holes in your ductwork at all. Unless more shows up, I wouldn't worry about it.
2) If you should need some work done in this area, professionals have the necessary safety equipment to allow them to work with all kinds of insulation even if it contains asbestos. You shouldn't have trouble getting someone to work on your system.

I notice you live in Estacada. There are several testing labratories in the state of Oregon. Most will allow you to send test samples to their office. The one I have used in the past is Clayton Environmental Services. They have a office off of I-5 at the Heidon street exit by Beaverton. There phone number is 503-968-2112. They send their samples up to Seattle with about a week turn around or 24 hour if rush. Cost is $20/sample, $30 if rush. DEQ normally gets involved so be aware. Several companies do abatement also but it can cost several thousand dollars to get asbestos abated. This is asbestos in its friable state so it will become airborne if disturbed.
