Embodiments of the invention are directed to a utility platform assembly a having a utility platform, an insulative liner, and a liner retention system. The insulative liner presents a complementary shape to, and is disposed in, the utility platform. The insulative liner is secured in place and protected from damage by the liner retention system. The liner retention system is disposed atop and through the liner near the top edge or edges of the insulative liner. The edge or edges of the insulative liner are therefore disposed between the liner retention system and the lip of the sidewall of the utility platform. The liner retention system generally comprises at least one retaining bar with an associated plurality of fastener receptors and fasteners.
