SUNTUF® Plus brings more lightinto greenhouses than any other material.

The chart data is based on test reports from Wageningen UR horticulture optical lab.

Optimized corrugation allows longer daylight time and stronger light penetration.

Light transmission in Corrugated Sheets vs. Flat Sheets:

SUNTUF Plus UV resistanceSUNTUF Plus maintains its high optical properties over time. A protective layer prevents UV related degradation of the material and makes SUNTUF Plus an ideal greenhouse cover.

100 hours of QUV machine are equivalent to 1 year exposure to UV radiation in areas of 160-180 kl.ls, such as the Mediterranean coast, Mexico & Central America, Central & south Africa, Australia & southeast Asia.
