det0326 179 Report post Posted May 3, 2016 Is this what most are using between the headliner and roof for insulation? How thick can you go before interfering with the headliner bows? http://www.ebay.com/itm/Reflectix-BP48010-Reflective-Insulation-Double-Bubble-Foil-48-In-x-10-Ft-/182048292747?hash=item2a62ec7f8b:g:x2YAAOSwP~tW33ug Thanks Dave 1 rosalindet16 reacted to this Quote Share this post Link to post Share on other sites

Raven R code 281 Report post Posted August 5, 2016 Did the Mach 1 come with roof insulation as a standard item? And if so, what is the best solution ? I'm not using dynamat but I will be using something. Quote Share this post Link to post Share on other sites

Yes they did . I pulled mine a few months ago. It is fibreglass bat material approx 2 inches thick. Quote Share this post Link to post Share on other sites
det0326 179 Report post Posted August 5, 2016 not sure if they all came with insulation or not but mine had the old yellow stuff that looks like some house insulation. Not sure if it is fiberglass or not it is just what it appeared to me to be like. I used the dynamat that they make especially for the underneath of the roof. It comes in 1/8 1/4 1/2 thickness. I used the 1/4 and it fit nicely and was really easy to install. Dave Quote Share this post Link to post Share on other sites

det0326 179 Report post Posted August 6, 2016 Anyone know who carries the correct stuff (thickness wise)? the thickness you would want to use depends on how much clearance you have between your bows and roof. from what i gathered when I installed mine I could adjusted the bows a little either way by bending the ends a little. I found that the 1/4" seems to work best tho. Dave Quote Share this post Link to post Share on other sites
1969_Mach1 333 Report post Posted August 7, 2016 Been a long time, But I installed the repro insulation and it was only about 1" thick. Quote Share this post Link to post Share on other sites
det0326 179 Report post Posted August 7, 2016 Yes the OEM was softer and thicker and would compress more than the dynamat. The dynamat like I used is more like foam and doesn't compress much. Someone might make a repo of the OEM stuff I don't know but if it is fiberglass I would not want to deal with it anyway. Dave Quote Share this post Link to post Share on other sites
