Starting the Insulation
Here we go, this is the most important part where most trailer builders or "DIY's" really fall down on the job. They forget that Insulation is about 50 - 60% and the other 40- 50% is air infiltration. It does not matter if you install R-99 or 10" of Insulation, if the air leaks in like a sieve, all around in 40 mph wind, you have just wasted your time and money, thats all. To do a good job you will also need to foam the metal rails and use lots of tape to get a good seal everywhere. As we go along I will try to give you some good tips on how to get the job done right. Its a messy job, but somebody has got to do it. Put as much as you can, wherever you can. I am using 1/2" , 3/4" , 1" and 1.5" whatever it will take to get the job done right.
Here is my tool holder, if this is empty nothing gets done.
