KNEE DEEP IN.....................FIBERGLASS.
( WHAT ELSE ? )
BECAUSE OF THE PONY WALLS, THE ONLY WAY WE CAN INSULATE THE ROOF WITHOUT ANY VOIDS IS TO BLOW THE INSULATION IN.
IF I WE WERE TO USE FIBERGLASS BATTS, AND CUT AROUND ALL THE PONY WALLS, THE R-VALUE WOULD BE LESS THAN WHAT WE NEED.
IN NEW MEXICO, ALL YOU NEED TO PASS THE ENERGY CODE IS
AN R-VALUE OF 38, OR 12 INCHES OF FIBERGLASS.
OBVIOUSLY, I DON'T THINK THAT'S ENOUGH.
IN THE PHOTO ABOVE, THE INSULATION IS ALMOST 28 INCHES DEEP.
MY INSULATION CONTRACTOR SELLS ME THE INSULATION BY THE BAG,
AND NOT THE SQUARE FOOT. ALSO BECAUSE IT'S CHEAPER TO BLOW
IT IN I CAN INSULATE MY HOUSE UP TO AN R-VALUE OF ABOUT 50 OR
MORE WITHOUT MUCH ADDED EXPENSE.
I ALSO USE RECESSED CAN LIGHT FIXTURES ( TYPE IC ) THAT ALLOW YOU TO COMPLETELY COVER THEM WITH INSULATION. OTHERWISE WE
WOULD HAVE TO KEEP THE INSULATION 3 INCHES AWAY FROM THE CAN TO
AVOID A FIRE HAZARD, WHICH WOULD CREATE A HOLE IN THE
INSULATION ALMOST TWO SQUARE FEET IN SIZE.
WITH 24 RECESSED CANS IT TENDS TO ADD UP.
