Grace Ultra...
OK, Sound deadening has been beat to death, but I think I may have
stumbled upon something new, and I'd like to know if anyone has experience with this product. Referencing what is widely accepted as the most comprehensive side by side test out there - http://www.sounddeadenershowdown.com/ - Much emphasis is placed upon butyl based deadening products... As such, I had all but settled on RAAmat. Enter today's trip to the local Building supply store... I (almost literally) stumbled upon a box of roofing underlayment sitting outside in the lumber yard. Grace Ultra. It had been left out in the rain, and they were planning on throwing it away. Well, it came home with me - and I think I'm glad it did. Here's the specs: http://www.na.graceconstruction.com/...ds/UL-005M.pdf It's only 30mils thick, but each roll is 198ft^2, and I just got one for free... I didn't ask at the time how much they were selling it for - I'll find that out tomorrow. From the tech sheet: Grace Ultra is composed of two waterproofing materials – an aggressive butyl rubber based adhesive backed by a layer of high density cross laminated polyethylene. PERFORMANCE PROPERTIES Property; Value; Test Method Color; Gray-black Thickness, membrane; 0.76 mm (30 mil); ASTM D3767 method A Tensile strength, membrane; 1720 kN/m2 (250 psi); ASTM D412 (Die C modified) Elongation, membrane; 250%; ASTM D412 (Die C modified) Low temperature flexibility; Unaffected @ -29°C (-20°F); ASTM D1970 Adhesion to plywood; 525 N/m (3.0 lbs/in. width); ASTM D903 Permeance (max); 2.9 ng/m2s Pa (0.05 Perms ASTM E96 Material weight installed; (max) 1.1 kg/m2 (0.22 lb/ft2); ASTM D461 Butyl based Adhesive It not stinky, the polyethylene is strong, and the adhesive is STICKY. Also, I read that it's designed for high temperature applications. What so you think? KeithS |

Grace Ultra...
Oh yea, I'm considering sandwiching a layer of rubberized asphalt based
deadener between the Grace in more troublesome spots... Triple the thickness, and avoid the problems of smelly asphalt(?) keith wrote: OK, Sound deadening has been beat to death, but I think I may have stumbled upon something new, and I'd like to know if anyone has experience with this product.

Grace Ultra...
THANK YOU FOR THE TIP!!!
I'm definitely going to check it out. I have tried ALL SORTS of alternatives to Dynamat (including asphalt based roofing cement sold in gallon cans which was dirt cheap and worked OK, but was hard as hell to apply and STUNK for WEEKS while it cured!!!). I appreciate the heads-up! Thanks. MOSFET "keith" wrote in message ...

Be interested to hear about your results... you've already addressed the main
concerns I'd have about it (how well it'll stick, especially in a hot car, and whether it'll smell bad) so don't need to "yeah, but..." those keith wrote: OK, Sound deadening has been beat to death, but I think I may have stumbled upon something new, and I'd like to know if anyone has experience with this product.
