I finally made it back onto the roof and after what is approaching a year, I found my reflectix in exactly the same shape as when I installed it. WoW, I am impressed! No degradation at all, maybe a slight, but very slight discoloration.
I wish I could attach these photos to the first post in this series but I do not know how to do it.
As you can see from the pictures, it is a very simple process to install the reflectix.
Please note the color of the reflectix on the a/c cover then the reflectix on the outside water filter. I added the reflectix cover to the water filter today and you can see the color difference between a year ago and today.
My wife cut reflectix to cover all of our windows and used small (tiny) pieces of sticky velcro to attach to the window screen frames. She used larger peices in the beginning but it just ripped the reflectix when removing so she used 1/4 inch pieces and just let the velcro edges overlap about 1/8in. using 6 pieces it works just great. easy on and easy off. We also used the velcro/reflectix inside each of the inside of the roof vent openings along with the interior lining of the exterior the roof vent covers.
We are enjoying significant cost reductions in both electric and propane gas for the heater.
I also used the reflectix around my outside clear case water filter to prevent algae and freezing.
