Question 1

Is this 50 or 80 mil material?

Accepted Answer

Ok, so I seriously doubt there is any way it is actually 0.01" as stated in the add description.
That is really thin for sound and heat blocking.
It is most likely a typo and should read 0.10" OR 100 Mil. 
It makes no sense for Amazon to create their own competitive product for this application at the same cost as several others on Amazon and then make their product 8 times thinner, but yet their matching package size weighs more.
Most others on amazon for this same product and size are 50 or 80 Mil thick.
The one I have been buying often is 80 Mil or 0.08" and it is thick and works extremely well. 
When you look the specifications side by side, they are the same dimensions wide and long.  
Then ship weight is clearly more on the amazon product.  
Amazon's own product almost has to be thicker to account for this added weight.  
I'm going with Amazon's product being thicker at 100 Mil or 0.01".
It makes much more sense to advertise same product but a bit better and the same cost.
They both cover the same square footage and are the same material with a foil cover and adhesive backing.
Amazon's product must be thicker, which would result in a more effective heat and sound blocking property.  
Since the two I am comparing are the same cost, I'm going to order the amazon product and give it a try.  
The worst that can happen is I return it for free.

Question 2

Does it come with a roller?

Accepted Answer

Yes. If you buy the 18" x 402" kit it will come with a red handle roller. Mine did.

Question 3

Not sure why every reviewer thinks this is a good deal, 36 sq ft of 80 mil material is $59 and the exact same quantity of kilmat is $57.99. explain?

Accepted Answer

Kilmat 80 mil is 0.5 lbs/1sqft. This is 0.7lbs/sqft (better per $)

Question 4

can this be used inside a house window to reduce noise from the street ?

Accepted Answer

No, it's for sheet metal use, dampening the noise transmitted through sm.  A better bet for you would be to buy some 1/8" thick acrylic sheet and silicone it to the inside of the window frame, creating an air barrier between the pane and the sheet, and to fill the area behind your walls with rock wool or fiberglass insulation.
