How to Install Your New Vent Insulation Block Inserts – Fast and Easy

Step 1:  Clean your vent openings… either brush them out with a broom/brush OR Blow them out with a leaf blower… wipe down with wet towel to clean as needed.

Step 2: Push closed the plastic vent cover that you may or may not have inside the vent openings. Typically there is a plastic flap that needs to be pushed closed… just please push on either of the top corners and the plastic flap will snap closed.

Step 3:  Simply, grasp the Insulation Block and insert it into one side of the vent opening (from the exterior of the building). The Insulation Block only fits one way… it will push in easily with the long side of the block on top. Push it all the way to the back.

You are done… Use your Blocks in the Cold weather AND the hot weather… it just makes sense.
