“If the project is in a coastal area, I always recommend polycarbonate,” -- Eric Huffman, a Senior Fellow with Eneref Institute and President of Daylighting Solutions

Examination of The Use of Polycarbonate in Commercial Skylights

“We found it simply does a better job when the sun is low in the sky,” explains Mark Jongewaard of LTI Optics, whose study demonstrated the efficiency and lumen output of the polycarbonate Dynamic Dome.

Polycarbonate is able to withstand impacts of over 50-70 ft. lbs, while acrylic breaks at 1.75 ft. lbs. Only polycarbonate passes the highest level (Class 4) “hurricane test” or “large missile test.”  Unlike acrylic, polycarbonate’s impact resistance far surpasses OSHA’s guidelines for fall protection or accidents in skylights.

New technology eliminates yellowing. A significant advance in polymer technology is a UV-absorbing “cap layer” that nearly eliminates sunlight damage to polycarbonate. Polycarbonate no longer yellows, hazes or degrades.

“We felt the polycarbonate was a stronger, more durable product,” said Senior Construction Manager Bruce Wallick, of furniture retailer Rooms To Go, who examined samples of skylight plastics prior to installation at their warehouse facility in Dunn, North Carolina.
