Insulated vinyl siding
It's not much harder to install then reguler siding, it depends on what brand it is.
In some cases it sits away from the wall so far it will need 1" J mounding and corners.
Sitting out that far you may have to build out all your windows and door trim.
Some do not glue the foam to the siding so it becomes a pain to cut.
That wide (about 7" exposure) siding was populer in the 70's but seems to have fallen out of style.
I've seen far to many DIY installs on vinyl siding, I would not suggest it.
The one's I get to see I'm having to go back and fix falling pieces, recutting some shorter or replacing them with longer pieces, adding siding blocks that were left off, fixing walls behind the J moulding that was installed wrong.
A really siding company will have all the proper tools and know how.
