white powder insulation in attic

[nick83]

i found balls of what i think is wall insulation in the loft space of my home i have recently moved into it is snow white in colour and is very light in weight, when touched it crumbles to powder can anyone tell me what this is as i don't know what it is and the health hazards

how old is the house?

 

[nick83]

its 1960's i was told from previous owner he thought it was wall insulation since he didn't install the insulation. the size of the balls are around snowman head size and were just lying around like they had been left there

the balls are around snowman head size and

I like it. Is that an SI, ANSI or imperial unit of measurement?

 

[nick83]

no its just the best way i could describe it cause they are all different sizes
