What is the recommended thickness for ice in a hockey rink?

The recommended thickness for ice in a hockey rink is established based on the type of play and the demand placed on the ice surface. For recreational use, maintaining a thickness of at least 1 inch is adequate because the intensity and frequency of play are generally lower, reducing the risk of damage to the ice. For competitive play, a thickness of 1.5 to 2 inches is recommended to ensure that the ice can withstand the high-impact actions and increased frequency of use associated with competitive hockey. This thickness also helps in maintaining the quality of the ice favorable for skating and puck movement during games.

Thus, the answer accurately reflects the guidelines for ice thickness, which balance both recreational and competitive needs, ensuring safety and performance on the ice surface.
