thriftily whether the spent energy for heating homes, to spend it on… then lowering the temperature for storing food in the fridge? Especially when the window — frost. A hang out of shopping bags or bags with eatables, arrange for the window boxes, like flower. But not all products need to be frozen. And the exterior of the house from such “decorations” are suffering. So I went the other way.
With the onset of cold weather I use a simple device mounted on the kitchen windowsill.
The idea is to isolate the part of the window from the warm room air. This can be achieved in several ways. The easiest way is to put on the window-sill a box with the width with the window open and a height of about 250 mm from plywood or plastic. Here will drain from the glass the cold air, filling volume and maintaining the lowered temperature sufficient for storage, such as dairy products.
For greater capacity of the refrigerator may need to increase the width of the sill, increasing its timber tongue and groove coupling at the butt, or putting it on top of the workpiece from a sheet of chipboard. If the frame is standard, dual, then such a cover will be included under the projecting lower edge of the sash Windows, and you don’t need to come up with additional bracing. But first, the workpiece must be luted and in several layers to cover the white enamel.
