That's an interesting idea as well, brother! I understand what you're saying perfectly! I've installed a good bit of this stuff, just never in this situation - open wall, Poly already on one side.BOSTONBUD wrote:You COULD slice the poly horizontally at the top and at the bottom. Effectively rendering the poly “breathable “. Then place the faced insulation in the void. The faced side has the additional paper where the staples hold it to the 2x4. This can be bent to underlap to the inside of the 2x4 and stapled from the exposed side. Hope that makes sense. I have found wire stays work well holding things horizontally but vertically long term I believe the insulation would sag/drop in the cavity.
I was curious as to the holding power of the wire stays over time. In my mind, it makes sense that the insulation would sag over time.
On a positive note! Fiberglass insulation does not affect me as it does other people! I can play in it all done - nothing! One exception was I got some in the bend of my arm and was grinding it in to my skin all day! Minor irritation!
Thank you, friend! I appreciate you!
