Effective thermal insulation
The Kelvin value for 8mm Thermoclear Multiwall is 3.3 and
for 10mm 3.0 - Thicker sheets have still lower K-values.
UV protection to both sides of sheet
Both sides of the sheet have co-extruded UV protection to provide
high resistance to yellowing and the damaging effects of UV radiation. This
feature eliminates the problem of sheets being installed with an unprotected
surface exposed to the weather with resultant UV damage. Angle cuts can be reversed,
so there is also an economic gain when cutting requirements are high.
