Does condensation affect the performance of polycarbonate sheet?Last Updated: June 05, 2018
In common with many glazing materials polycarbonate sheets can develop condensation as a result of environmental factors.
It does not affect the performance of multiwall polycarbonate sheets; the effects are purely visual and normally temporary.
Polycarbonate however is hygroscopic, with a 24h water absorption figure of around 0.36%. Therefore it is possible that condensation can form within a sheet's structure in spite of all the precautions taken especially where extremes of temperature and humidity occur. Because it is a natural phenomenon condensation is not acknowledged as a fault of the material and is therefore excluded from product performance warranties.
