Direct2Fab TopLite Unit Skylights

Pre-assembled unit skylights up to 7' wide and 23' long


CPI Daylighting developed TopLite Skylights in response to the Energy Code requirements for skylights with higher insulation and more light transmission in a covered space.

TopLites are typically larger than traditional acrylic unit skylights and provide much better insulation. CPI Daylighting offers TopLite pre-assembled oversized unit skylights with the industry's best ratio of insulation to light transmission (double the insulation of traditional acrylic unit skylights), resulting in effective and economical energy performance.
