ABSTRACT:
Movable insulation is provided with sealing structural components to minimize or eliminate for practical purposes infiltration and convection currents in and around the movable insulation to enhance the thermal insulating quality of the assembly. Seal strips on the edges of the insulation pocket forming material layers are adapted to slidingly engage seal guides provided in the side frame channels of the assembly to seal the sides. Weight bars in the lower extremities of the insulation forming material sheets enhance the seal on the bottom as well as to keep the layers of material separated, and rotatable separating rollers on top also help to keep the layers separated and to form a seal on top. A smooth operating manual chain drive and anchor mechanism is provided, as well as a removable decorative fabric for the front of the assembly. Alternative embodiments enhance the seals and insulating quality of larger movable insulation assemblies, including top seal guide extensions for separating the layers, a bottom curved seal guide for accommodating the lower ends of edge seal strips to prevent binding and loss of bottom seal by accommodating differential length movement of front and rear layers, and edge seals for inner layers adopted for sealing edges as well as for maintaining layers separate in non-vertical applications.
