Sealing Twin Wall Polycarb Greenhouse

[rhyswales]

Hi all

Just bought new twin wall polycarbonate glass for my greenhouse as the old had gone cloudy and was full of algae. I'm just wondering the best way to seal the edges to prevent moisture and algae.

I've read on the internet some use aluminium tape for the top of the glass and breather tape for the bottom, this any good?

Thanks

I didn't use anything on mine - was not aware you neeeded too.

I didn't do anything to mine, either.

I used this to keep pests out & to stop condensation between the walls:

Thanks for that. Did you seal the top and the bottom of the glass with the tape?

Yes I sealed both ends.
