Could you please be a bit more specific? I really don't know what you're asking. Sounds to me like a simple matter of insulating said wall?
I'm not familiar with this process and don't even see the point if the patio is not enclosed and heated. I'm going to open this backup to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
Good afternoon. My name's Kel. I just found your question. When you mention entrance I'll assume you're referring to the entrance of the house. The detail you're mentioning has three aspects. First is to insulate from the footing to the top of the foundation with 2" of board insulation. Second is rough grade the area from the foundation out five feet. Dig to provide a slight pitch to allow for drainage. Second is place 2 to 3 inches of sand and rake that smooth. Then apply 2" inches of board insulation. Then cover with poly then cover with top soil or concrete. If there's light foot traffic from the patio through the entrance you can position the insulation so it's covered with three inches of concrete. The thinner the insulation at the entry the less thermal bridging you'll have. Provide a joint between the patio and house to serve as a bond breaker and thermal break. Does this make sense? Have I answered your questions?
