closed in a screened deck and made a glassed in sunroom. Used backer rod to fill in the gaps between deck boards. I'm relatively sure the rod doesn't have a large R value, but it stopped the wind from blowing through the floor. It did make it possible to heat the room with a mini-split (which is not overloaded). It has kept the sunroom quite comfortable during winter (temps down to 8F). If it works as well in the summer heat, I'll give it high marks as an insulator.

I’ve been using very thin backer rod for posting my dog’s ears, and it’s been a fantastic solution! It’s lightweight, flexible, and provides just the right amount of support without causing any discomfort. It’s easy to cut to size and stays in place securely. Plus, it’s gentle on the ears and works perfectly with sports tape. Highly recommend for anyone looking for a reliable and comfortable ear-posting method!
