What is the insulation value (R) of Coverseal?

Unfortunately, too many factors are taken into account to establish an accurate theoretical calculation of the insulation value of the Coverseal (delta T°, air mass trapped under the membrane, wind, rain, etc.). Therefore, it is not possible to quantify it, but the Coverseal ensures an almost perfect seal, blocking almost all evaporation. This significantly reduces heat loss, which leads to real energy savings and limits the need for water filling, for more sustainable and economical management of your pool.
