Insulation between garage and living space above
I've been working on my garage project and I'm about to the point of
installing insulation on the garage ceiling. The joists between the living space above and the garage are 22" inches tall and manufactured from 2x4's. Inside them is the plumbing, electrical and most of the hvac flex ducts for the room above. I also plan on insulating the garage walls. I have insulated garage doors on the front and back but the front one is big, 20x9. The subfloor above is tongued osb. Does it really matter which way I put the facing on the insulation between the garage ceiling and the floor above? I know the vapor barrier is supposed to be against the floor but i's going to be a whole lot easier to install it with the paper on the garage side as that will let me staple the paper to the bottom of the joists. Otherwise I have to figure a way to hold the insulation up while I install wallboard on the ceiling. |

Vapor barrier to the heated side or potential problems Thee are metal supports made for holding insulation in place between joists. . Better applications is to have someone come in and do spray foam. |

They are about the size of a coat hanger and come in different lenghts. These wires will hold up the insulation by being inserted between the floor joists. Easy to do, no tools, inexpensive. Hank |

Hank- Hide quoted text - - Show quoted text - Yes, I know about insulation wire supports. These are open web trusses centered on 24". That makes the open space between trusses 20 1/2". I'll have to cut 24" wires down a bit. And carefully place them on the lower edge of the truss. I'm wondering if there might not be a better solution than the wires. For what it's worth the insulation is in 4' batts. |

Maybe someone has a bunch of old metal clothes hangers you could cut. How much is your time worth? |

For what it's worth the insulation is in 4' batts. I have an old house with uneven joist spacing. What I do is temporarily push up the insulation and zig zag (sort of, I run across and zag) staple fence wire to keep up the insulation. You can staple the wire to the inside of the joist. You can cut insulation to fit the gap. It's a pain cutting it and I usually use a large paper cutter and chop my way through. Vapor barrier is supposed to go to the heated side. In a hot climate that may change how it is installed. Jeff |
