ABSTRACT:
An apparatus for facilitating the installation of a flowable insulation in a wall or ceiling cavity comprises a rigid rectangular frame. A pair of transverse runners releasably receives an apertured slide panel and a pair of slide screen panels. When all three panels are received by the runners, they extend between the sides of the frame. A metal screen or wire mesh covers the frame other than at the runners. The apertured panel may be repositioned by removing one of the panels and sliding the other two to a different position then reinserting the removed panel. The frame may be pressed against a wall cavity and the apertured panel positioned so that it is not obstructed. An insulation hose may then inserted through the aperture in the apertured panel and insulation blown into the cavity; subsequently the apparatus may be removed. In another embodiment a pair of adjustable legs extend from the bottom of the frame and a row of teeth extends along the top of the frame so that the frame may be pressed against the top of the wall cavity. In a further embodiment the adjustable legs may be pivotally joined medially along the sides of the frame and used to support the frame against ceiling joints so that insulation may be blown into the ceiling cavity between these joints.
