How to Store Polycarbonate Sheets?
Polycarbonate sheets are tough and durable and guaranteed to last for years.
Here are some tips for storing polycarbonate sheets to ensure you get the most out of your investment.
Polycarbonate should be stored horizontally on a flat surface, such as a pallet or a shelf. 
Ensure that no nails or bolts protrude from the platform. Even small rocks can leave permanent dents and scratches on the sheets.
Stack the largest sheets at the bottom, and the shorter, smaller panels on top.
Avoid stepping on polycarbonate panels and placing heavy or sharp equipment on them.
Store the polycarbonate sheet in a dry, cool, ventilated, shaded area away from direct sunlight.
Keep your stack dry to prevent whitening and water spots.
Avoid covering the sheets with dark films or other heat-absorbing materials.
Cover the panels with an opaque, bright, waterproof cover if you intend to leave them outdoors.
What is the best polycarbonate panel for thermal properties and light transmission?
There is a trade-off between light transmission, transparency, and thermal properties in polycarbonate sheets. Multiwall polycarbonate sheets provide superior thermal insulation over solid sheets, but they are translucent, not transparent.
Clear polycarbonate panels will be fully transparent, but less thermally insulating.
Both options allow high light transmission, depending on their color.
If your main concern is light transmission, and not a glass-like appearance, you can achieve that with multiwall sheets, such as SUNLITE, or with the SUNPAL architectural multiwall panel system.
If your main concern is clarity, your best option is PALSUN solid polycarbonate sheets, or SUNGLAZE architectural solid panel system.
Another important factor to remember is that multi-wall sheets weigh significantly less than solid sheets. This can lower your construction and labor costs.
