View Full Version : ADDING INSULATION IN ATTIC

09-20-01, 04:01 PM
I HAVE A 13 YR. OLD HOME WITH AN UNFINISHED ATTIC. PRESENT INSULATION CONSISTS OF ONLY BLOWN FIBERGLASS. IT BARELY COVERS THE 2X4 CEILING JOISTS. I WANT TO INCREASE MY R-VALUE TO 38 OR MORE. SOME, BUT NOT ALL READING MATERIALS ON "HOW TO INSTALL INSULATION" RECOMMENDS NOT TO LAY BATTED OVER LOOSE FILL. WHAT I WOULD LIKE TO DO IS PLACE FACED BATTING IN BETWEEN THE JOISTS THEN RUN UNFACED BATTING PERPENDICULAR TO THE OTHER. WILL IT CREATE A PROBLEM IF I DO NOT REMOVE THE LOOSE FILL FIBERGLASS FIRST? THANKS FOR YOUR HELP.
