This is offered as a custom item. The panels can be made with additional layer of “Thinsulate like” material. Our standard covers provide a layer of insulation (see pic), however, this insulation is EXTRA for extreme cold temperatures.
Extra insulation – Charge is per cover, so if purchasing a front door cover item, that would be two covers in that set. You would need to add quantity of 2 at a cost of $50 ($25 each)
