You could try wrapping the run with clear shower curtains to block the wind and it gives it the greenhouse effect when the sun is out.Mine is a lot warmer in the run with the shower curtains plus it doesn't block the sun.
I imagine it depends on the fastening technique and the location in relation to prevailing winds.awesome ! do the hold up in strong wind?
Could you post a link to the product you purchased?I bought mine off Amazon, heavy duty commercial grade holds up well I zip tied the heck out of it so the wind doesn't grab it, so far so good. I will feel better when we get some snow around the bottom I won't shovel it to give it some weight.
