front cap insulation

I have a 12 Georgetown. Had a year, no leaks. went to Fl. for winter. the water would pool on the dash from so much water. I worked on the roof ,windows lights all winter long could not get the leak fixed. Go home to Ohio in mid Apr. put it in the shop. NO LEAK, they did find NO insulation in the area you are talking about and added 15 ft. of 3 1/2 insulation to stop the dampness and water running down the window from it. Cold outside like 45 hot inside, heater on , humidity high . yep $330.00 later, 3 1/2 of insulation, rain like heck this spring and NO LEAK.
All that to say , YES insulation it for more than one reason. BTW heading to In. for new dash in July all because someone forgot to insulation:h

Yes, the front cap. I do have the 454 and heat off the engine and cast iron manifolds is also an issue. I my work on that also. There is some kind of material they glue on to the firewall in race cars that is supposed to help.

I'm talking about the big airspace behind the front TV and cabinets. Once we are parked, I have the big silver screen I put in the windshield. That really helps a lot. My front cap is tan in color. I was thinking of stuffing the pink stuff in there.

I do the same with the big silver screen in my Adventurer John, I'm not going to tackle the front cap until my T.V. goes out! Then I'll get in there and insulate better. I live in the rainy Pacific N.W. and I don't deal with the extreme summer heat like you do! Good Luck

I purchased R13 insulation wrapped in plastic from Home Depot and doubled it up in my overhead area that you are referring to. I did this in conjunction with my LED TV upgrade. Works well.;)

I used Denim Insulation available at Home Depot, etc. I think it has made a big difference as my front cap is painted black

This looks like a good idea. I'll look for it next time I'm in Lowes or HD.
Thanks!

I think he is talking about the front cap above the windshield, but I have had two 454 engines in motorhomes and they both ran very cool.

My American Tradition has this foil around the engine and where ever there is the possibility of heat intrusion.
Insulation Foil Roll

I would glue this to the inside of the front cap and anywhere I could reach. I use this in AZ in place of the front curtains to greatly reduce the heat in the coach.

I never have, however, I'm in the process of switching out my TV's and a lot of the other electronics and changing the cabinets around. Having that space to work it is very nice. So if you do add insulation just remember you may need to get in there some day to run wires or fix things so you may want to use an insulation that can be removed or worked around.
