I am in Houston, Texas. I am combating high heat coupled with high humidity. My shop is a 2-car garage. Above the garage is an enclosed attic area. I have replaced the garage door with an insulated door. This alone cooled the garage by at least 5 degrees compared to outside.
I know there have been a number of posts on this topic. I have read quite a few and still haven't come up with a answer. These are the specific challenges that I am facing:
(1) Garage door must stay
(2) Side walls are brick with hardy plank attic above garage
(3) HOA will have fit if whatever I do can be seen from street
(4) Do I need to put vapor seal / thermoseal around garage door???
(5) How to cool garage at reasonable cost???
Open for suggestions...
Thanks,
Edward
