I want to blow insulation into my attic. The door into my attic is on the floor and made up of a large board which doesn't have hinges. I have to push the door up and slide it over in order to gain access to the attic. That means when I blow in insulation, I can't blow any in on the door or in the area that I will slide the door over to.
Will this gap in insulation cause major hot or cold air loss? Are there alternatives to this?

They make insulated covers for folding attic stair cases. You could use that basic design to make your own insulated "cap".

Consider using a different type of insulation on top of the door (i.e. fiberglass bats) in addition to your blown insulation elsewhere.

You don't put blow in above the door. Use batts or cut several layers poly board insulation to mimic slightly less than your attic cover. 4-5 layers will give you good coverage.

This will not provide a perfect barrier but is the recommended way of handling attic openings.bb

I'd create a xps perimeter inside the attic to prevent the loose insulation from falling down. This will also help achieve the correct depth near the opening.

@FreshCodemonger - that is always a good idea. The issue with the new blown in insulation is keeping it from dropping all over when going into attic.
