A multi-layer insulation having an aluminum layer, a first foam layer positioned on one side of the aluminum layer, and a second foam layer positioned on another side of the aluminum layer. In one embodiment, the first and second foam layers are polyolefin foam layers such as polyethylene foam and polypropylene foam. The aluminum layer is an aluminum foil and may be provided with strengthening layers. Alternatively, the aluminum layer is a metallized film. Preferably, the various layers are laminated together. In another embodiment, a multi-layer insulation includes a first foam layer, and a second foam layer laminated to the first foam layer, at least one of the foam layers being provided with at least one extending lip sized to allow interlocking of the multi-layer insulation with an adjacent multi-layer insulation.
