Butland, currently on loan at Barnsley, has one senior cap to his name and is an outside shot to go to the World Cup squad.
However, he wants to earn a place on merit and not benefit from Hart's errors.
He said: "I know Joe very well. We speak every now and again but I gave him space for the last couple of weeks (because) the last thing he wants is people telling him things he already knows.
"He's fully aware of the situation but if there's one thing I know about him it is that he will be absolutely burning inside to get back playing.
"I'm sure this short stint out of the team will make him even stronger.
"He will come back even better than he ever has done before in the World Cup year.
"I have total confidence in him, he has had a tough time and when you have the England number one tag it brings a lot more pressure and attention."
