Acrylic or Polycarbonate Sheets for Greenhouse?

[Doug99]

A few of my 2mm plastic side wall sheets have been blown out.
Looking to replace with 3mm but Acrylic or Polly?
What are the pros and cons?
Cheers all

Polycarbonate, Doug.....much less brittle than acrylic and easier to saw and plane.

Poly. As Burnerman says, less brittle, (read more flexible), especially after being exposed to sunlight. It's also what most green houses use as standard these days.
