Inserting Rows In Variable Positions?

I'm analysing some data sets with variable content, and need to insert blank rows every so often to provide space to do some analysis. The problem I have is that the position of the blank rows change according to the data set, I have been able to calculate how often the row needs to be inserted using VBA as part of my import routine and saved this value to a cell, but I cant figure out how to write the VBA which will insert rows using this value and stop at the end of the data set.

In the attached example I need to insert a row each time the data in column 2 (name) changes, this is the value I have calculated which in this example is 7. So in this attached file I need to insert a row in row 2, row 9 and so on etc. But this is what changes depending upon the "Product" held in colum 1.
