This product is easy to cut and shape for any area
I had been using rolled insulation to insulate the folding stairs leading to our attic and it was old and would bunch up and obstruct the steps. I used two layers of this product and it does the job better with no movement and takes up less space. Great product for a tight space.

Attic Wall Reflective Roll Air Bubble
Would RecommendI think it will work okay, but I still have work to do before I will know for sure. Our plan is too help insulate the lower level of our greenhouse so that on frosty, not freezing mornings, the greenhouse will be able to preserve some of the previous days warmth overnight
