I ve added extra insulation, but it s not as efficient as I thought, why?
Cold air is heavier than warm air, so if you have not insulated the drain in your ice box you could be losing your cold air that way. Depending on the type of insulation used and the method of installation, gaps may have occurred or the insulation may have been unevenly applied. Most insulation depends on tiny air pockets to provide a barrier to heat loss, if the insulation has moisture trapped within it, it will reduce it s efficiency. Check for any moisture, before applying the insulation. The bottom is critical but often a very difficult place to add additional insulation to the exterior of the box. Check out our space age insulation which can be applied to the interior of the ice box as an alternative.
