Spacer for insulating glazing unit

A spacer assembly for insulating glazing units;

• the spacer assembly comprising:
• a silicone foam rubber spacer body having opposed faces and an outer face extending between the opposed faces;
• an adhesive tie layer adhered to each of the opposed faces of the spacer body;
• and
• a primary adhesive adhered to the adhesive tie layer;
• a moisture vapor barrier disposed along the outer face of the spacer body;
• and
• wherein outer corners of the spacer body are defined at the junctions of the outer face and the opposed faces and the moisture vapor barrier is turned up around the outer corners of the spacer body to a height that is more than half of a height of the spacer body.

A spacer assembly for insulating glazing units;

• the spacer assembly comprising:
• a silicone foam rubber spacer body having opposed faces and an outer face extending between the opposed faces;
• an adhesive tie layer adhered to each of the opposed faces of the spacer body;
• a primary adhesive adhered to the adhesive tie layer;
• and
• further comprising a primer between the adhesive tie layer and the spacer body.

A spacer assembly for insulating glazing units;

• the spacer assembly comprising:
• a silicone foam rubber spacer body having opposed faces and an outer face extending between the opposed faces to define a pair of outer corners of the spacer body;
• a tie layer adhered to each of the opposed faces of the spacer body;
• a primary adhesive adhered to the tie layer;
• and
• wherein the tie layer includes a mixture of a silicone functional amorphous polyalphaolefin, a hydrocarbon resin, a paraffinic process oil, and an epoxy-functional silane.

A spacer assembly for insulating glazing units;

• the spacer assembly comprising:
• a silicone foam rubber spacer body having opposed faces and an outer face extending between the opposed faces;
• a primary adhesive adapted to adhere the spacer body to glazing structures;
• the primary adhesive including polymers;
• and wherein a majority of the polymers of the primary adhesive comprise at least one of butyl rubber and polyisobutylene polymers;
• and
• a primer disposed between the primary adhesive and the spacer body to promote adhesion of the primary adhesive to the spacer body.

A spacer assembly for insulating glazing units, comprising:

• an elongated spacer body having opposed faces;
• the opposed faces being non-parallel to each other to define non-parallel geometry;
• and
• a layer of primary adhesive disposed on each of the opposed faces;
• each layer of primary adhesive having a thickness sufficient to compensate for the non-parallel geometry of the opposed face on which the layer of primary adhesive is disposed;
• each layer of primary adhesive having a thickness from about 0.254 mm to about 1.524 mm thick.

A spacer assembly for insulating glazing units;

• the spacer assembly comprising:
• a spacer body having opposed faces and an outer face extending between the opposed faces;
• a primary adhesive disposed along the opposed faces;
• a moisture vapor barrier connected to the outer face of the spacer body;
• the moisture vapor barrier being connected to the spacer body with the primary adhesive.
