Greenhouse Covering Insulation Comparison

Compare the insulation rating of Solexx to other greenhouse coverings on the market. The higher the R Value, the better the material insulates. Solexx even beats 8mm triple wall polycarbonate! A greenhouse with good insulation has many benefits:

  • Traps the Heat: Keep frost at bay to extend the growing season
  • Better Heat Retention: Save energy costs when you want to heat
  • Less stress on plants: As outside temperatures quickly drop at night, the temperature inside the greenhouse changes slowly
  • The better the insulation, the lower the condensation

R-Value - the measurement of 'insulating ability' of the material. The higher the R-Value number the greater the insulation value.
U-Value - the measurement of 'heat loss' through the material. The lower the U-Value the less heat is escaping.
