Question 1

Can this product be installed against house wrap and than install lp lap siding?

Accepted Answer

For best insulatuve results,be sure to create at least a 1 inch air gap between layers.

Question 2

I need to put on top off my existing wall and covered with wall panel on top of is that ok

Accepted Answer

It may be ok but it won’t do much. A radiant barrier needs at least a 1/2 air gap between it and the hot side so it can reflect the radiant heat.

Question 3

can you install this on a roll up door

Accepted Answer

I use spray adhesive or double sided foam tape to attach it to the doors, sealing the air spaces. It works great. The foam tape also prevents conduction of the heat through the metal frame of the door.

Question 4

If I was to put the radiant barrier against my vinyl siding then put the waterproof/plastic covering the radiant barrier the plastic waterproof melt ?

Accepted Answer

You should run this on the very top of your exterior. It must have an air gap to be useful.

It should go like this 
exterior: 
OSB/Ply/Zip etc. (SHEATHING)

*Optional* IF, you're using an exterior insulation then you'd run that (I'm using 1" Rigid Foam XPS).

*Optional* Filling my seams around the 1" Rigid Foam using spray foam (in the can). Helping to create an airtight seal.

House wrap (Tyvek). This is debatable, some say to run the Tyvek underneath the exterior rigid foam and normally I'd agree. BUT using the radiant barrier it is suggested by almost all manufacturers to ensure your radiant barrier has an air gap and reflects out.

*Required* Create your air gap. Using whatever you wish ie. Wood or foam, you make furling strips. I am using a 4' x 8' of the 1" rigid foam cutting that into 2" wide 4ft long strips. I marked my exterior studs with a blue chalk line (ensuring ease for location of my 16" OC and studs). Now running my 1" foam (Furring strips) down the sides and one in the center using liquid nail and screw/nail into each one.

After I have created my air gap I used the radiant barrier (one sided) shiny side facing out towards the world. Stapling them up and then using the foil tape to create the air seal.

You can then run your siding on top of the foil and you're done.

Short Answer-

Exterior-
*SHEATHING (OSB, PLY, WHATEVER)
*Exterior Insulation (Optional) seal the seams
*Tyvek (tape the seams)
*CREATING YOUR AIR GAP- Running your Furring Strips down your stud bays and adding a center furring strip to ensure gap remains.
*Staple up your Radiant Barrier (Shiny side facing out) Seal your seams.
*Siding
