So this is tried and true by yours truly in other equipment, so I thought that I would share. By the way this wasn't my idea, but unfortunately I don't remember where I saw it so I'm sorry for not giving you credit.
This is my new L5740 Grand. Since I had to remove the roof for other mods, I thought I'd go ahead and do the simple insulation install. In some of my other equipment, the roof didn't come off, but the headliner came down and I was able to install the same way. Your just working upside down.:laughing:
I bought this at my local True Value hardware store in the home insulation section. It looks like bubble wrap made of Mylar. It's very thin, pretty cheap and makes a huge difference in your heat and a/c. I think it reflects more energy than actually insulates, but you get the drift.


I used Gorilla tape. It is 100x better than duct tape, but more expensive.

Cut to fit and tape in place. Just that easy.
You'll notice that you have your heater and your a/c turned down the next season. In my opinion, I think they work half as hard.
