Is this safe to install over radiant heating AND will it fade in direct sun? Thanks!

Mannington Adura Max Waterproof Planks can be installed over radiant heating system, provided the temperature of the floor does not exceed 85°F at any point. Concrete floors with a hydronic radiant heating system are satisfactory. Before installing the flooring, the heating system should be turned on to eliminate residual moisture. A combination of heat and sunlight causes most home furnishings to fade or discolor. We recommend closing your curtains or blinds where extreme sunlight hits the floor.
