Replacement greenhouse glazing: glass or twinwall

Hello 👋 
I have inherited a neglected and damaged greenhouse (moved in with partner, it belonged to previous home owner). This weekend I cleaned it so I could sow my seeds/bulbs, but the broken panes still need to be replaced. I can’t decide it if it’s better replace the glass like for like, or replace it with clear plastic twinwall (corrugated plastic). If I went for plastic I would rearrange the panes so all the plastic was at ground level.
It’s probably worth mentioning that the hedge and tree nearby which might have contributed to the breakages have now been pruned so I’m hoping for less breakages!


  • Oh I should also add, plastic is £5 per panel, glass from local glazier is £9.50 (which is good).
    I need 12 panels in total so it’s a bit tricky to get enough second hand panels in the right size.

    Light transmission is best with glass, but twinwall plastic is warmer. Your choice of course,  using the plastic at ground level makes sense.

  • Thanks Allotment Boy. I am liking the idea of the twinwall at ground level. I have no idea which is more eco friendly.

    Another option would be to use Acrylic sheets which the supplier will cut to size.
