Abstract
There is disclosed a soft and compliant spacer body wherein the body is provided with modified substrate engaging surfaces to accommodate transverse dimensional changes when the spacer is bent about a corner or otherwise flexed in an insulated assembly. In one embodiment, the corners are cut to reduce the thickness of the strip as the same is bent or flexed about a corner. Other embodiments are disclosed. The advantage is that when the transverse dimension is maintained relatively constant about the bent corner, the result is a more effective seal between the substrate engaging surfaces and the substrates. This is augmented by the use of cellular materials and selected sealants to provide multiple sealing surfaces in a high efficiency spacer body.

An insulated assembly formed from spaced apart substrates and a spacer between said substrates, said substrates and spacer defining an inner space containing an atmosphere, said spacer comprising:
- a flexible resilient body including a front face facing towards said inner space and a rear face in spaced relation, a first substrate engaging surface and a second substrate engaging surface in spaced relation with said first substrate engaging surface, said front face having a portion of material removed from each corner formed between said front face and one of said substrate engaging surfaces for substantially reducing an increase in said transverse dimension of said body when said body is flexed.
An insulated assembly formed from spaced apart substrates and a spacer between substrates, said substrates and spacer defining an inner space containing an atmosphere, said spacer comprising:
- a flexible resilient body including a front face facing said inner space and a rear face in spaced relation, a first substrate engaging surface and a second substrate engaging surface in spaced transverse relation with said first substrate engaging surface;
- a portion of material removed from said resilient body proximate each said substrate engaging surface at said front face for substantially reducing an increase in the transverse dimension of said body in the transverse dimension when flexed;
- said substrate engaging surfaces including a first sealant material for providing a first sealing surface;
- and
- a second sealant material different from said first sealant associated with each substrate engaging surface to provide a second sealing surface.
