Help Prepare And Close Kennel For Cold Weather, But Be Able To Open Back Up For Summer!

Hello Aussie Lovers and community.

I'm a proud owner of Three Aussies! Winter is vastly approaching and I need your trusted advice on how to prepare my kennel with materials that can easily be removed in the summer. I have a 40 foot long section coming off of my garage with 4 5x10 pens and 1 10x10 pen 6 ft high.

To help keep them warm and safe I need to know the most economical way to close the open areas for winter and yet be able to enjoy the open kennels in the summer??

Near Future plans are to add a fence for easy access to the outdoors!

FYI! During the summer my Aussies help me lose several inches all over & lose up to 10 lbs., by vigorous walking/hiking 2 mi. 4 to 5 times a week!
