Insulation in Cockloft
I was looking at my cockloft the other day. Typical park slope brownstone. The insulation is very old, at least 60 years. Maybe original 1889? Has anyone had this removed and replaced? Who does this kind of work? Costs?? Can i just insulate over the old stuff?

Don’t try to remove the old stuff – it’s probably really dirty and falling apart. Just put more insulation on top.
Blown-in insulation will settle down a little bit over time, but when they put it in, definitely make sure they leave an inch or two between the top of insulation and the underside of your roof joists, so that the hot air can move freely and escape through the mushroom vents.
Federal Conservation did mine too.
My 90 year old neighbor in PA would love to get that sheep’s wool. She’s dye it and spin it and weave it into a rug.
OK, guess not.
Sheep’s wool. I like that. Does it work?
Seriously, parkedslope! I was once discussing the house with my landlord, and when I mentioned the cockloft to him he looked as if I’d said something really, really dirty. I had to explain to him what it is – and I still don’t think he believed me (like when I tried to explain to him that it was a bad idea to smash down all the solid plaster walls in the building down to the lathes and replace them with (no doubt made in China and formaldehyde-exuding) sheetrock – It’s more modern! *sigh* Guess I won’t be buying this house.).
We had Insulate America do ours, and I think they did a great job. Just blew in cellulose over the existing stuff which, iirc, was sheep’s wool. Seriously.
I’ve noticed a difference already this year. When we went through that crazy heat wave in the spring, the house still got insanely hot. But since then, it’s gone up to 80 or 90 outside, and throughout my house it would be in the mid 70’s. We’d open the windows at night, and it would stay pretty nice throughout the day. That didn’t happen last year before we put in the insulation.
And totally agree on the silver roof. A huge deal.
Cue Beavis & Butthead:
Cockloft!!!!
vent goes on top of the roof letting air escape from cockloft
I don’t know, mopar.
where do the vents go?
cockloft to roof?
