Does anyone have a solution for adding insulation thicker than the
studs? It's behind a knee wall area in my attic. Google came up with a
few patents on devices but I haven't seen anything for sale. The only
thing I thought of was butting 2x4s against the old ones and nailing
them together. Any better ideas?
That would help. But what do you plan to do after, cover it. Also
where do you live. If you are in a colder area you might want to
conside staggering the second row of 2 X 4's and over lap the
I am not going to cover it. My plan was to just extend the studs so that
I can install single rows of R-30. There is 2" fiberglass between the
studs now, but I am going to remove it. The old insulation has cardboard
stapled over it. A lot of it is falling down and looks as if it has
absorbed moisture. I am in Rhode Island.
Where did the moisture come from.
Is it the result of improper or no vapour barrier on the warm side of
Or insufficient ventilation on the 'attic' side of the insulation?
Just adding (replacing existing) insulation without determining why
dampness may have occurred could merely repeat the process. Damp can
mean mould/mildew and rot.
