Is there much of an R value to sheetrock?
I'm getting ready to do the exterior walls in my garage (workshop)
here in the Portsmouth, NH area. I'm going to use R-19 exterior (2x6 walls) for the insulation. But I was thinking, they have this silver pegboard at HD that would be kind of cool to use. My question is how much of a loss would I suffer if I JUST used the pegboard and skipped the sheetrock (1/2") altogether? The garage will be heated. The dimensions are 20x20x11 and it is new construction. Thanks in advance. -Jim |

Should have one on the exterior, of course, if the builders didn't tear it full of holes and did a good job of it. Wouldn't hurt to add an interior for certain. -- |

The dimensions are 20x20x11 and it is new construction. As others have noted, the fire and draft resistance of drywall are quite important. A proper moisture barrier is important as drywall will pass water vapor and absorb condensate, becoming gummy and stinky over time. Interestingly, much of the fire resistance is due to water chemically bound in the plaster. When heated, the water escapes which carries energy away from the drywall, cooling it. -- FF |

I am going to use 5/8 sheetrock on the ceiling with insulation above it. This is really only for three walls, one of which has the garage door in it, and the other has 4 large windows in it. So the main area is really the one opposite the interior wall and that is about 20x11. I mean, I would only be using the heat on the weekends and maybe occasionally in the evenings, else it would be set down to it's lowest setting so that it wouldn't freeze (FHW) |

The dimensions are 20x20x11 and it is new construction. The sheetrock per se doesn't have much R value, but it serves to seal the inner surface of the wall, thus creates a closed air cavity in which convention is suppressed by the fiberglass, so by not using it you may lose more than you would expect just from the R value of the sheetrock. In a wood shop I think you'll find that fiberglass behind pegboard is a continuing annoyance--pegboard holds amazing amounts of sawdust that comes out at inconvenient moments, so does fiberglass. The two together, well you may end up needing to put up another building in which to apply finishes.

The biggest benefit of sheetrock is to protect the plastic vapor barrier. So if you put up peg board the punch through the plastic (and you will at some time), you let the moisture in and it will condense in the insulation. |

Why not put up the drywall, prime & or pain tit, then use nuts (spacers) to
mount partial sheets of pegboard. You need a little gap to re&re the hangers of all types. I have extras. Theres 2 standards, and I garbage pick hangers all the time. Sams as all stores. Proportion sheets, orient, and space on walls to suit each or all. I did it in my garage. Besides, aligning the holes with spacers with whole sheets is tricky. I have third sheets with 1-1/2" between them. Doesn't take too many screws/bolts . ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

The most additional "bang for the buck" would undoubtedly be in an insulated door and better windows if either or both are not presently. The floor slab is a big heat sink as haller notes if there's not been any consideration of doing something there... -- -- |

The two together, well you may end up needing to put up another building in which to apply finishes. That's something I can speak to. 1/3 of my garage is pegboard over insulation. That's were my shop area is. The other two bays are sheetrock. It's been this way for almost 15 years. I paint cars in those other two bays and I've never had an issue with sawdust. It might well be argued that sheetrock would have sealed over my insulation better than the pegboard does, but in Central NY where the winters are cold and blustery, I've never noticed any real shortcoming with what I have. -- -Mike- |

In my house, I was renovating and insulating the walls in the living room. I briefly thought of drilling holes and blowing insulation, but eventually decided I couldn't stand the wall material and pulled it down and hung drywall. If it had been a garage, I'd have just drilled and blown the insulation in. -- Tanus This is not really a sig. http://www.home.mycybernet.net/~waugh/shop/ |

Jim,
I have used peg board over sheet rock. I wanted the fire retarding aspect. ONE KEY POINT. This approach requires theat the peg board be spaced off the sheet rock !!!! Paul "jtpr" wrote in message ...
