This is a 2 ft by 4 ft sheet of aluminum-faced double bubble insulation, sold with six peel-and-stick adhesive squares. The foil surface reflects radiant heat while the trapped bubble layer slows conductive transfer, so it works as a lightweight, cut-to-size barrier for windows, garage doors and attic spaces. It is a simple DIY material rather than a finished panel: you cut it to fit and hold it in place yourself. Compared with fiberglass batts it is thinner and easier to handle, but it offers far less R-value per inch, so treat it as a supplement rather than a primary insulation.
