Searched but didnt see anything. I have access to 10 rolls of this stuff (50 ft x 6 inch) for next to nothing, and what interested me was the ability of this product to act as a decoupling layer between drywall/studs. If you're not familiar with it , its a rubberized tar like roofing sealing/flashing tape in 70mil thickness. Its quite heavy and sticks to most anything. Just tried putting some between 2 24x24" pieces of sheetrock and stuck them together to make a sandwich. Not only could i not remove the two once joined, they sounded totally deadened by it. I didn't cover the whole thing either, just applied in 2" strips in 4 places. Is it a crazy idea to use this between the sheetrock, and where studs interface with each other and the sheetrock to minimize sound transmission?? Has this been approached before anywhere in a thread i missed? If so, please direct me or give me some input to whether i should go through with the effort...i'm getting the stuff for free basically.
Anyone used Jiffy Seal 500/700 for decoupling??

Look for the green tape conversation on pics. This is similar to what you are proposing.
You've not mentioned what type of frame you're going to build either: single, staggered, double... so it's hard to guess on a non-proven method of building a wall. For the most part, we don't like methods that are not proven around here.

Its similar in application but different in composition comparably. I've seen the green tape and agree it doesnt have the mass and damping quality. Whereas, Jiffy Seal can be doubled over and over, to any thickness, and when you drive a screw or nail through it, the product is designed to seal around the penetrating object. Also, it actually bonds so well that i'm contemplating using it to adhere the two layers of drywall without using screws (for sidewalls only) and just a dab of construction adhesive. This would sort of mimick GG, allowing for less pathways for sound to travel to the studs. Its all concept at this point, and i will be testing it before i go and use it. BTW i will be using a staggered stud wall design, double 5/8 drywall, room in room design. I have a drawing but no way to upload it yet... :(See this thread: http://www.johnlsayers.com/phpBB2/viewt ... 63&start=0 Look for the green tape conversation on pics.

1st, is this the product we are talking about:
http://www.protectowrap.com/cat_roofjiffy.php
OK,
I would not trust that, the application product is meant for is completely different from what you are proposing. This stuff is meant to lay on roof sheathing with shingles over top that are nailed in. The stickiness is to prevent moisture penetration.it actually bonds so well that i'm contemplating using it to adhere the two layers of drywall without using screws (for sidewalls only) and just a dab of construction adhesive.
No product has not been talked about on this forum yet that has real test results behind it to compare it to green-glue. Reading through http://www.greengluecompany.com/ I have a hard time imagining how this construction would be similar.This would sort of mimick GG, allowing for less pathways for sound to travel to the studs.
Comparing this the the use of RC or iso clips... RC and iso clips (with hat channel) are only useful on single frame walls or ceiling. Adding RC and iso clips to double frame wall is almost pointless... very,very,very little OR no gain in isolation. Have you thought through staggered stud construction all the way the end? Staggered stud was once in my plan but building double (decoupled) door and window frames on a staggered stud (2x6 plates w 2x4 studs) will be next to impossible. Would have to go for the supper single door plan and advanced window frame notching out studs for window and using 2x4's on side. Also building the inner and outer ceiling decoupled from inner and outer staggered studs properly will be almost impossible. I don't have a lot of room for my studio but still dropped the staggered stud idea and have gone for double 2x4 frames. You may want to wait for one of the Pros who frequent this forum to comment but:BTW i will be using a staggered stud wall design, double 5/8 drywall, room in room design.
IMHO, yes it is. Most importantly because one of the biggest guidelines around here is to not use any unproven construction methods. MarcIs it a crazy idea to use this between the sheetrock, and where studs interface with each other and the sheetrock to minimize sound transmission??
