Radiant Barrier Attic Insulation - Reflective Insulation - Attic Foil - 500 Sq Ft Roll - Foil Insulation - Industrial Strength, Commercial Grade, House Wrap, No Tear, Double Sided

First time reflective insulation. Easy to cut and secure to rafters. I use this in an I insulated wood shed with a an aluminum roof. I made a tube that captures the air at the peak of the roof and funnels that air to vents on each end of the shed. Dropped the temperature considerably and my small AC is ableto cool the area.

I used this product on my metal roof porch. It helped keep the Temperature down to bearable.

I used it as a underlay heat barrier and as a house wrap. Very easy to handle. Cuts easily but does not tear. Does not twist and blow excessively so you can roll out a length and staple it without getting a twisted mess. The only caution is that it does reflect heat and sun; working with it keep that in mind. It acts like a suntan reflector.

This foil has already made a noticeable difference in our metal building, which is right out in the open sun, with no shade. We haven't gotten our regular insulation put up on the walls, but it feels like maybe an 8-10 degree drop on the inside heat. I can only hope that with the other being put up within the next week, a much bigger difference will be felt. For the price, I am very happy with our purchase.

Works great. If u have R11 and u use this product you have better than r19.

It was perfect a little bit short for the area I needed but did the job

Used this on several sun penetrating areas and works great here in Florida.

Easy to work with, using behind siding like housewrap.
