Windows Glazing: 3 Facts to consider

The windows glazing (Window Caulk, Glazing Compound, Wiring and Other Similar Materials) that secures the glass panes to the frames is known as window glazing. This may can contain asbestos and should always be screened, treated, and disposed of properly.

Windows Glazing

As you may have heard if you follow Es-America news, asbestos can be found in a variety of areas in older homes, including walls, under linolium and carpet, in or behind heating appliances, in toilet cisterns and seats, in meter boxes…

But did you know that your windows could contain asbestos? Asbestos can be found in putty used to seal windows, particularly in houses built in the early and middle decades of the twentieth century.

What was the purpose of using asbestos in window glazing?

Why, of all things, would asbestos be used in window putty? Asbestos was utilized in construction products for the same reasons that it was used in other products: it added strength and fire resistance. Fire resistance is a very desirable feature in window putty. Some putties are intumescent, which means that when heated, the material swells, increasing in volume but reducing in density.

As a result, the putty is highly effective as a sort of fireproofing, protecting the surfaces on which it is applied from heat damage. Asbestos was most likely present in these varieties of putty. (Ironically, asbestos-containing putty was also widely employed in US naval warships!)

As with most asbestos uses, the use of asbestos in window putty was motivated by good intentions. However, as a result, old windows are now merely another source of asbestos exposure, particularly during restoration or window replacement.
The risk increases over time as the putty weathers and begins to degrade.

Anyone who has ever spent the winter in an unrenovated older house will be familiar with this issue: the putty around the windows becomes so worn that it no longer accomplishes its function of keeping the cold out. Many people resort to using interim fixes such as insulating tape in the meanwhile, but the putty is still progressively wearing away and becoming friable, posing the risk of asbestos fibres being discharged into the air.

ES was amazing! Highly recommended. I called in a panic about a wall we had to remove and they came the next day and had results the following morning. The inspector that came was professional, kind, and super informed. Don't hesitate. Call them!

We needed an asbestos report for a tear down and rebuild. It couldn't have been easier they showed up took the samples they needed and quickly got the report back to us back to us in a couple days. Elias Hernandez was our services agent 👍👍👍

I was contacted promptly after inquiry, Eli was great in explaining where specifically the asbestos was found in my older mobile home, and how it was to be removed before the structure could be demolished. Job was done great and within the timeframe they stated in the estimate. Would definitely recommend.
