There is a school of thought that says working on your own home with your own hands is a source of deep satisfaction and manliness. For me it has been a source of deep seated physical pain and discomfort.
We decided a while back to install some insulation underneath our home, and this was a very good idea. It probably would have stayed an embryonic idea had it not been for some firm pushing by our friends Lisa and Josh who want to do the same thing on their larger house. So our's was the guinea pig, as it were, the 700 square foot (65 square meter) home which because it was built in 1987 is lower to the ground than Josh and Lisa's newer 1,000 square foot stilt home. Ours may be only eight feet above flood plain but installing strips of fiber glass matting still requires holding one's head back and stretching out one's arms.
Eight hours of this crap yesterday with bits of prickly insulation spilling all over oneself can put quite a dent in the notion of how uplifting home improvement really is. We spent about a thousand dollars on strips of fiberglass in 6 and 3 inch depths, we spent some of that money on staple guns and staples, masks gloves and goggles and we hope this attempt to make our home "greener" will reduce our already modest electricity bills. We generally pay about two hundred dollars a month in summer with the air conditioning and less than fifty a month in winter so it will take a while to enjoy the benefits of reduced costs. The benefits of reduced heat and noise are immediate.
Plus there is the satisfaction in knowing we've done what we can to make our home more energy efficient and that offsets to some degree the absolute agony of my joints and my burning, aching feet.

I decided to hire some help and Roberto made it all possible with his wiry Cuban frame tirelessly bending and lifting and stapling like an automaton. It was all we could do, Josh and I, to keep up. I have to say we were lucky with the weather. This bizarre fog has been hanging around a bit longer than usual so the early morning was cool and damp and even as the sun came out it never got really hot under the house. Nevertheless we were sweating, and even though we had calorie-less cola on hand, Roberto sucked it up like he was a pansy sugar-free gringo, until our wives showed up loaded with cafe con leche for the troops:
We took wads of the cotton candy and stuffed them between the wooden joists overhead:
Then we took the thinner strips of insulation and tacked them up underneath the six inch deep insulation strips:
The last step will be completed by a pro who is supposed to show up at some point and tack weather -proof sheeting over the cotton candy to finish the job. It will be brilliant I am sure, and even I think we were all aching by the end of it...
...it was a worthwhile job well done. On another note the greening of our windows was much easier to deal with. Captain Jeffrey, the most talkative window tinter in the Keys, came by and with a splash of soapy water and a few quick slices of his box cutters stuck some really remarkable silver tint on the south and west facing windows and doors. From the outside the effect was astonishing, a pure mirror reflecting almost all of the sun's heat:
From the inside the effect of the silver coating is to give the view a polarized look which is actually quite pleasant:
Additionally Jeffrey added some very dark tint to the sliding doors and the window in the bedroom so now I have a very cool, dark, refreshing place to sleep during daylight hours. It was a nice job, swiftly and efficiently done for $600 by the smiling Captain:
I suggested to Lisa and Josh they might want to do the same to their windows because we all know energy costs are going to go back up and we all want to be ready for the summer heat this year. I can hardly wait to prance around sticking insulation under their house. The purity of self sufficiency has to be enjoyed to be understood.

You may want to check with an expert before you have the sheeting installed, but it has been my understanding that the paper side of the insulation (the vapor barrier) is to be placed against the floor. I believe your installation may be incorrect.
Your intentions are to be commended. I did have a question along the lines of the comment before mine. How is any possibility of trapped moisture avoided?
The insulation and window tint will help with the electric bills. One last item you try is a $30 hot water timer switch if you don't have a tankless water heater already. So far our bills have gone down $20-30 a month.

I'm no insulation expert either, (and I didn't even sleep in a Holiday Inn Express last night)but from most of your photos it appears that the vapor barrier is correctly installed as it is attached to the "floor" portion (or the cieling of your bottom deck as it were, depending on how you want to look at it). On the one photo you can see the vapor barrier, however, I'm assuming that portion already had a strip of insulation installed in that area and that the stapled other piece was simply a "doubling up" effort. In any event, nice job! I've done some insulation projects in the past and I'd rather have my spleen removed with a grapefruit spoon than to undertake the endeavor again... After having done it, I can certainly understand why insulation people charge the prices that they do.
Jeffrey: we've talked about a tankles sheater but initial investigation indicates our pipes are too narrow(!) so I am going to get a sleeve for the propane eater. My apologies, I wrote this last night more as a lament for a broken man than as a how - to. The insulation barrier of the R-19 (6 inch) is facing up towards the floor and the layer of R-13 (3inch) is facing down to create a sandwich. I am now negotiating to have the professional come next weekend and close this aching chapter in my life. If he says tear it down I shall default and take up a place in my sister in law's ashram in India.Josh has now set some dates to go kill ourselves at his place with the benefit of this experience. PS I also did four hours of overtime last night after an hour's sleep.Erk.

In the unlikely event it all has to come down, just remember, slice lenghtwise starting at your wrist and upwards towards the elbow... across the wrist is the tell-tale sign of a novice...
Gads, this conversation went downhill fast! Conch, you are using gas for your water heater? Interesting, have not seen that much here. I have been looking at the solar water panels lately and found some on craigslist. I think I know my next home improvement project (although I am like you and really disdain them).
Jeffrey... The panels work fairly well, albeit rather unsightly on the roof... Had a good friend who would laugh at my pool heat pump as he used a solar panel and it was actually surprisingly efficient (if you can wait 3 days for it to heat the volume of water in the pool). But definitely worth looking into! And yes, the convo did take a dark turn indeed..
Conch:
Your heating/cooling expenses are UPSIDE down. We are around $200. Winter & $50. Summer
I hope your insulation is installed correctly, it would be a shame to splatter blood everywhere un-necessarily

My wife saw solar water heaters on homes in Turkey. Josh says he knows how to build them. My projects are my way of defying the crisis. We shall see.
Don't forget, you can get a tax credit and a rebate for solar water and electricity panels in FL. One per lifetime of the homeowner (and you can get one and your wife can get another if you bought a different home). The rebate can be for up to $20K, but it is so much per kilowatt generated. Here in CC, they only have one way meters, so anything I generate above my use flows back to the grid, but I don't get credit for it. I hope they fix that soon.
Your batts are compressed far too much. You're supposed to tuck them in gently with as little compression as possible.
Bit late for you, but your friend should look into spray foaming the floor instead of batts. It seals much better and the insulation value is higher, is more critter/insect proof and quicker to put up with no itchy bits. I don't think a vapour barrier is required either.
If you're still set on batts, look at Roxul. It's a mineral wool that is less itchy, has a much higher fire resistance rating than pink batts and doesn't cost that much more. It's also made from left over mining slag, so it's "greener" I guess.
