FW: [forum-l] asbestos in window glazing (Nelson, Marie) ---------------------------------------------------------------------- Message: 1 Date: Fri, 9 Jan 2009 15:48:27 -0800 From: "Nelson, Marie" Subject: [Calclg-l] FW: [forum-l] asbestos in window glazing To: Currently there is a thread on the National Trust's Forum listserv regarding historic window restoration projects. I am forwarding part of one of emails because the information at Historic Homeworks may be of use to your historic homeowners. The message reads: "I am currently working on a window restoration project in an 1881 observatory in Wisconsin. The glazing in these windows was determined to contain asbestos so the contract required it to be removed by an abatement contractor. I asked the contractor for his procedure to remove the glazing since it was I was trying to retain as much of the original glass as possible, and the response was that he was going to chisel it out. I recommended that they borrow my steamer since I knew it would result in a greatly reduced number of broken windows. The abatement technicians were impressed with the steam method because it softened the rock-hard glazing and minimized any potential airborn asbestos by keeping the material damp. Historic Homeworks ( http://www.historichomeworks.com/hhw/index.htm ) is where I got the idea to use a steamer. The steamer I used is a Jiffy J-4000 ( http://www.jiffysteamer.com/Products/index.asp?steamerCatId=5 ) Considering the method prescribed by the contractor, I imagine they will complain that steaming is slow as compared to breaking the panes. This is likely true, but if the goal is to save the windows that I would recommend that they give steaming a try." I will add that others have pointed out that the small amount of asbestos present in the glazing as a result of putty repairs in the past constitutes no real threat and can be encapsulated by painting.
