![]() I have to make four removable storm windows for the skylight in my house. They are trapezoidal so there will be a lot of waste. I will need two 4X8 sheets.
Acrylic is less expensive than polycarbonate. I'm not concerned about impact damage. The question is which will hold up better under heavy sunlight and semi-regular cleaning. Acrylic can be polished if it gets scratched. I've never had any luck removing scratches from polycarbonate but then maybe I didn't know what I was doing. Any recommendations? |

![]() Acrylic tends to shatter into shards if it breaks. Polycarbonate not so much. Lexan likely has better UV resistance also so should last longer in the sun.

![]() Sheet grade polycarbonate and acrylic sheet are two of the most frequently used see-through plastics. Acrylic is shinier and polycarb is stronger. Acrylic is less expensive but easier to crack. Polycarb is more impact resistant but easier to scratch.

![]() Acrylic. Acrylic Acrylic. Polycarb yellows in the sun and is much easier to scratch. When I built my first house, I used acrylic.
We are used to double pane glass which has a lot of reflections. When clean, the acrylic windows were so beautiful because they looked like there was nothing there. The garden looked like it was an extension of the house. |
