How to tack up 2″ rigid foam under rafters?

Nick H | Posted in General Questions on

It sounds like people use cap nails…but I can only find them in a 2″ length (at most).
Are there longer nails available? Or am I missing a key step in installing the foam boards?

    Any chance t2.5"+ are sold at brick and mortar stores?
    I was hoping to find something locally.
