Insulation

I have a 25'x30' steel building that im trying to get up and running. I need to insulate this thing and have no idea where to start. Just wondering what some of you have done to your steel building/garage as far as insulation goes. kinda off the wall subject but any help will be great.

Do some trade work with a contractor, lol. I hate insulation, that shit sucks!

im too lazy for all that, so my shop stays hot in the summer, cold in the winter!

I did insulation for about 8 years. the easiest way is rigid polystyrene panels.they come in lots of r-values and you can just glue them up with construction glue. If you dont want to do it yourself..do NOT call a company to do it you will get reamed. go to your nearest housing subdivision where they are still building houses and look for insulation installers tell them you have a side job for them..they will probably be able to help you out. when we did side jobs we would do a 2 car garage for 100 bucks and that was walls and blown fiberglass in the ceiling..the company charged about 800 for the same thing. or call a spray foam company but its messy and it sticks to everything.

the spray foam is the best but i do believe its pretty expensive.
