We're having 4 pot lights and two pendants installed in the kitchen. The ceiling has an insulated attic above it. Is it a problem, because the vapor barrier will have to be cut?
You will need to add the blue plastic boxes above each pot light. And tape them to the existing vapour barrier with red Tuck tape in order to seal the surface for air leakage. They sell the blue plastic covers at Home Depot or electrical supply places.
Keep in mind that this work will require removing a large portion of the ceiling if there is not enough room in the attic to work. Also the new pot lights will need to be the type that are encased in a galvanized metal box, not the small retrofit pot lights.

Yes you can unseen cut a 2 by 2 foot section for each pot light, keeping in mind that if it trusses it will be 24 in centres but if it is hand cut in could be 16 inches centers.
Then yes get the plastic boots required from your local Home Depot and red tuck tape.
Have a great day.
I have always been a firm believer in overkill when it comes to safety.
I strongly suggest that you have someone go into the attic space and add the steel box units for pot lights to sit below. These add a much greater amount of air space around the pot lights themselves. And the bulbs will not burn out as fast either because you will keep the temperature cooler by the light.
Be sure to install insulation over the units or you will have cold spots in the ceiling.
Your potlights will likely be installed by an EC. While the attached picture is not exactly the same as your situation, it is close enough so you get the idea.
In your case the blue box will be on the other side of the vapour barrier and tapped from the top.
