You could even buy insulation and floor boards that are already bonded together which makes the job much faster and easier.
It creates a breeding ground for mold and mildew and ruins the air trapping pockets that block heat flow.
With a more complete layer of insulation throughout your attic you ll experience lower energy costs and more effective heating cooling compared to simple batts installations.
Box out light fixtures.
Look for water stains on the roof sheathing or damp or moldy spots on attic joists and existing insulation as a clue to where leaks might be.
Additionally insulation serves as a way to enhance sound proofing on the uppermost envelop of your house.
