EPDM is highly resistant to both extreme heat and extreme cold, and can be used outdoors in very cold temperatures. EPDM will even maintain its flexibility and elasticity even in cold weather. This makes them ideal for use in colder climates where other types of pond liners may become brittle and prone to cracking or other damage.
However, over time EPDM may steadily become less flexible and stiffer in very cold temperatures, which can make them more difficult to maneuver and install. To minimize the risk of damage or failure, it's important to refer to your manufacturer's information to ensure that the liner is installed properly and isn't exposed to excessive stress or strain. If you live in a colder climate and plan to use an EPDM liner for your project, make sure to choose a high-quality liner that is designed specifically for cold weather use.
