The main consideration in choosing fabric for your dome is longevity. The two causes of deterioration are UV and mildew. If you live in a dry desert-like area with high UV, we recommend SunLite painted with Thermoshield, which reflects heat and UV off of the dome cover and dramatically extends the cover’s life expectancy. We also recommend SunShield because of its additional laminate coating protection against UV.
If you live in a damp or wet area with high moisture, we recommend SunLite and SunShield (vinyl) fabrics because they have a smooth surface, are easy to clean and are more resistant to mold and mildew.
