EconoHome Double Bubble Reflective Foil Insulation Roll - 4'x125' Metal Foil Heat Radiant Barrier for Walls, Attics, Air Ducts, Windows & Radiators - Energy Saving Home & RV Insulation for Summer Cooling & Winter Warmth

My small stand alone freezer I have had for 15 years with No trouble. I opened the lid and all the insulation fell out of its place so I thought what now? did not want to buy a new one, so I bought this to replace the original that fell out and added some freezer tape to hold it in place. To my surprise it works great the freezer is as cold as ever, before I did this the freezer lost like 30 degrees now back to normal at 12 degreesI am very happy with this product.
