Roof insulation?

These are probably the same guys that say Peel & Seal stinks like asphalt in a hot parking lot. They don’t realize that it is the tar that is stinking...not the asphalt.
About three years with P&S on the bottom side of my roof with no problems...and it gets hot here in middle Georgia too.

 

I googled it, and read way more bad things about Peel n Seal than I did about Dynamat, where the biggest complaint about it, is the price.

 

You will always get the nay sayers on a product that isnt meant to be automotive, I went with the peel and seal as well and have not had any problems with odor, savings can be spent on other needed items.

I used an insulating product called reflextric on the roof, it is a double sided foil with air gap bubbles like bubble wrap inside it is about 1/4" thick, got it at Lowes and is about $16.00 for a 25'x 2' roll, you have to glue it on but there is enough on one roll to go over the roof twice.

 

wonder how many used it and didn't like it or "they read".
how many have "you read" that ...did like it?
when I read about something being expensive, my thought is ...it's not worth the price...

 

I used Peel n Seal inside my Comet ... and for one of its intended purposed ... fixing a gap in a gutter. This is exposed to Florida sun 365 days a year and rain and wind, etc. This includes being basically underwater in some of the heavier rains. It has been there for 3 years now.

All that being said.... PnS strikes me as being good at sound deadening and reflecting radiant heat. I used that as the first layer, and the stuff that is more like silver-foil-face bubble wrap (Reflextric, mentioned above,another Lowes product) as the second layer for my floors. Because it is foil-lined, it too reflects radiant heat, plus acts more like insulation due to the fact that it has trapped air, etc, (plus it gives the carpet some cushiness). If I was to use one or the other under the headliner, I would likely use Reflextric .

I used both under the carpet to get all the benefits of both, as opposed to just using two layers of PnS. My carpet did not come with padding.

It kind of comes down to asking if you think you need sound deadening in the roof. You can accomplish a great deal of that by using PnS or Dynamat as a patch in perhaps the center 1/3 of the panel ... you don't need to cover the whole thing. You will kill most of the tendencies of that panel acting like a drum. I used PnS in this manner on the front parts of my wheel tubs and inside the rear quarters.

 

Most of what I read, was where people had problems. it's not hard to find.

 

got a link?
all I read were where people...read/heard...no one showed pics. of the problem...

 

Here's one

That's the post I saw too, Got another day or two to think about it.

 

I am starting to lean towards the bubble stuff glued to the roof. If it falls it is lite. Probably use a strip of P&S in the center.
I also think it is the prep work that makes a difference if it comes loose sooner than later.

 

I always think, when something isn't being used as it is intended, and you read about problems, then it's not worth the risk. If something is made for a single purpose, and you read more positive reviews (but there are always negatives, since people don't follow instructions) then I'm usually more than certain it will do the job.
It would really suck to have anything start to peal off the roof, above the headliner, let alone drip something..

 

Anywhere but up there. Too much involved to have it fail in that area.

 

thanks...that's one..."(but there are always negatives, since people don't follow instructions)." DaveB

maybe mine stuck because I wiped it down with...grease and wax remover...first...

...from the same link..."I used the "Peel & Seal" on my Maverick, works great! The only downside I can see is if it ever needs to be removed it will require a ton of work to get it off"...he's from Texas...

I read where a car with a 302 Ford motor quit running going down the road, had to have it towed home...stay away from them... BAD motors...

 

I do believe the guy from Texas is Russ..

I have been torn on which way to go on mine. I was thinking about just going with Dynamat Extreme just because I know I should not have any issues in the future.

Has anyone used any of the padded Dynamat material they sell?
