what do you know about drywall? (in Off-topic)

so today im at work, long day renovating a large residence built at the end of the war, mostly made of concrete for structure and sandstone exterior, anyways come to find out i have to demolish this wall(oh the fun!) which of course had drywall on both sides, the odd thing was that when i broke it up i noticed fibres in the drywall, i thought i was fibre glass but given the nature of the building im told its horse hair.

so yea, does anyone, if anyone have extensice knowledge of construction back in the 40's-50's or got any links i can read up on this, construction and demolition is great, though tough, and it gives me interesting thing s to read up on.

Yeah I work in the building game and the boss was saying something about horse hair used to strengthen the plaster/render/dry wall. He also said that it carried a disease that you could actually catch via contact from the horse hair. Funny eh? Disease from the dry wall, lead poisoning from the paint. Not very bright are we?

Definitely horse hair. We had that in our plaster walls when we moved into my late great-grandmother's (maysherestinpeace) house.

Here's an article with some info on drywall vs plaster.

Plaster old and new

and dont forget asbestos along with your led and diseases
