I'm re-insulating a room in my house, and have come to the corner. The studs are arranged like so:
x| | | - -
x = the space I'm talking about, | = studs of an interior wall, - = studs of an exterior wall.
Peeking in, I can see there is some loose fibreglass insulation in there.
Question: What should I do about that space? I can see 3 possibilities
- Try to rip out as much of the existing insulation as possible (maybe with a linoleum knife?), and try to re-fill with Roxul (the insulation I'm using for the rest of the project.
- Same as 1, but fill the space with Big Gap Filler
- Don't try to remove the existing insulation, and just stuff a little more Roxul in there.
What would people who actually know what they're doing suggest?
