What I received I’m Not so sure would be considered Twinwall. Only one side was smooth the other side was bubbles. I went ahead and used it anyways so we will see how insulated it is. Other than that ACF greenhouse was very easy to buy from and shipping was quick!!

ACF Greenhouses: We only carry bubble coverings that are twinwall. Yours should look like the pictures below. If not, please reach out to us, and we will be happy to replace it!

   

Used in our porch for the winter as a thermal barrier and it was a very quick and painless install. We felt the temperature difference immediately.

Bubble wrap performed as advertised. Easy to install. Delivered on time. Worth the price.

We felt an instant buffering from the cold as we’re were installing it in our porch It’s a cold 50 deg outside and 69 deg inside. It’s been installed for fifteen minutes and the porch is roughly 65deg now, and there’s no heat out there (just the door to the house open).

I have too many houseplants and little room to fit them inside during the winter, so this will house them for cold season (with heat pads), and I can start my seeds earlier now (especially the marigolds) with the porch a converted green house!!
