Teardrops n Tiny Travel Trailers

Appreciate all the great information here! I’m planning either a 7x14 or 7x16 build. Just curious what your total cost for insulation was.

Figuring the number of sheets by the square footage should get you pretty close.
Side walls... 14'x6'x2=168
End walls.... 7'x6'x2=84 V front will have a little more.
Roof.......... 14'x7'=98
Total sqf .......... 350 Subtract for doors and windows if you want. But you will have waste also.
Divide by 32 (sqf/sheet)...350/32=10.93
Multiply by cost of sheet...11 x 19.00= $209.00
Add a couple cans of spray foam and maybe some foil tape.
