A block of insulating material which increases in thickness from one end to a maximum at the other end is used to fill the wedge-shaped recess between adjacent rafters and the junction between the vertical wall and the rafters. In one embodiment it is placed on the flat upper side of the ceiling panel between adjacent ceiling joists and in another embodiment it is reversed and engaged against the sloping roof panel between adjacent roof rafters. In both embodiments, the insulation is blown against the curved surface and the increase in thickness of the pillow maintains a relatively constant R value to the outer surface of the wall.

A wall line insulation pillow locatable with a wedge-shaped recess defined by adjacent roof rafters, roof panels extending therebetween and adjacent ceiling joists and ceiling panels therebetween, said pillow maintaining the insulation R value between attic insulation and the outer surface of a structural wall, comprising in combination a substantially wedge-shaped block of insulating material having a first planar substantially rectangular face, a substantially rectangular wall extending upwardly from one edge of said first face to distal edge of said rectangular wall, spaced and parallel side walls extending upwardly from said first face and a second face extending from said distal edge of said rectangular wall to a junction at an edge of said first face opposed to said one edge thereof with the thickness and hence the R value of said pillow increasing from said opposed edge of said first face towards said one edge thereof at said rectangular wall, said pillow, when in situ being situated with said first face forming the base thereof and engaging said ceiling panels between adjacent ceiling joists and air vent means being formed through said second face from the front to the rear thereof, said rectangular wall joining contiguously with said first planar face at a corner whereby said pillow can be slid into place in said wedge-shaped recess with said first face in contact with said ceiling panel until said second face engages said roof panel, and a flexible membrane secured by one edge thereof to the junction between said first and second faces and depending downwardly therefrom when said pillow is in situ between adjacent roof rafters.
