Findings

10.9°C difference in pallet temperatures measured
Measured at 12:27, 22 August on Amsterdam tarmac
26.4°C in foil blanket
15.5°C in Tyvek® W20 cover pallet

These loggers were in top center boxes of the respective pallets.

were in Amsterdam on 22 August
28.4°C measured on foil blanket (Comp) cover at
14:27
16.0°C measured on Tyvek® W20 cover at 14:48

Conclusions

Available data clearly shows that the Tyvek® Solar™ W20 covers
offer a better protection than the foil blanket in this trial

Tyvek® covers also offer additional benefits of
being breathable
lightweight
water resistant
easy to install

Tyvek® is readily recyclable
which may not be the case for the foil blanket as it
is a laminate of spunbond material and aluminium
film.
