Acrylic vs Polycarbonate

Skyspan dome skylights are supplied with acrylic domes as standard, however polycarbonate domes can be specified on request.

Acrylic is the preferred standard material because:
- it has excellent long-term UV stability
- it resists yellowing, clouding, and embrittlement over time
- it maintains clarity and structural integrity for longer periods in Australian conditions
- it offers very good impact resistance for skylight applications

Polycarbonate is:
- initially stronger and more impact resistant than acrylic
- often chosen where short-term impact resistance is the primary concern

However, polycarbonate is more susceptible to UV degradation over time. Prolonged exposure to sunlight can cause it to:
- discolour or haze
- lose strength
- become brittle earlier than acrylic

For this reason, acrylic generally offers a longer service life for roof-mounted skylights exposed to constant UV radiation.
