Patent ID: 7748169

Claim:
An insulating panel attachable to a building, the building defining a building aperture, the building aperture defining an aperture plane extending substantially thereacross, said insulating panel comprising: a membrane structure defining a first external wall and a substantially opposed second external wall; a peripheral wall extending between said first and second external walls, said first external wall, second external wall and peripheral wall together defining an enclosure; and an internal wall system located between said first and second external walls, said internal wall system being configured so as to divide said enclosure into a first cell located substantially adjacent to said first external wall and a second cell located substantially adjacent to said second external wall, said first and second cells being substantially spaced apart respectively from said second and first external walls by said internal wall system; said internal wall system being configured so as to divide said enclosure into a first layer of cells including at least two first layer cells and a second layer of cells including at least two second layer cells, said first layer cells being located substantially adjacent to said first external wall and said second layer cells being located substantially adjacent to said second external wall, said first and second layer cells being substantially spaced apart respectively from said second and first external walls by said internal wall system; said membrane structure defining inter-cell apertures extending between at least some substantially adjacent cells from said first and second layers of cells; said inter-cell apertures being located and configured so as to define at least two groups of cells including cells from said first and second layer cells that are, within each group of cells, in fluid communication with each other, said groups of cells being separated from each other by substantially fluid impervious wall sections of said internal wall system, said substantially fluid impervious wall sections substantially preventing an exchange of fluid between said groups of cells, said groups of cells including each a respective number of cells, said numbers of cells defining a substantially geometric progression; and a frame attachable to the building, said frame being operatively coupled to said membrane structure for maintaining said first external wall substantially parallel to said aperture plane and substantially in register with at least a portion of said building aperture when said frame is attached to said building.
