MIDR71836 Midwest Canvas - 18' x 36' Rectangle Silver Solar Cover
These silver solar covers are available in 16-mil U.V. resistant material. Silver solar covers provide passive solar heating to your pool, meaning they act as a conduit for sunlight. Solar covers are a fantastic way to use free heat from the sun to warm your pool water during the day and prevent heat loss at night. They work by capturing and transmitting heat directly into your swimming pool while allowing for maximum sunlight absorption.
