Abstract
This invention provides a sealing spacer for spacing apart two window panes to form a window assembly. The spacer has an elongated, flexible strip having opposed edge surfaces and opposed side surfaces. The spacer also has a fiber reinforced polymer layer over the elongated, flexible strip. The opposed edge surfaces undulate with crests and troughs. The spacer has an activatable sealant for directly sealingly securing the flexible strip to each of the two window panes. The activatable sealant is on each of the opposed side surfaces of the fiber reinforced polymer. The invention also provides methods for making the spacer and window assembly.
Claims17
A sealing spacer for spacing apart two window panes comprising:
- a) an elongated strip having opposed edge surfaces and opposed side surfaces, wherein the opposed edge surfaces undulate with crests and troughs;
- b) a substantially flat strip having an inner surface and an opposed outer surface;
- c) a first adhesive adhering the inner surface of the substantially flat strip to the crests of one of the opposed edge surfaces of the elongated strip;
- d) a second adhesive adhering the outer surface of the substantially flat strip to a fiber reinforced polymer having a top surface and opposed side surfaces, the fiber reinforced polymer shaped to cover the outer surface of the substantially flat strip and the opposed side surfaces of the elongated strip;
- and
- e) an activatable sealant on each of the opposed side surfaces of the fiber reinforced polymer.
A window assembly comprising:
- (a) two window panes sealingly adhered to opposed side surfaces of a spacer assembly by an activatable sealant;
- (b) a spacer assembly for spacing apart the two window panes, the spacer assembly comprising:
- i) an elongated strip having opposed edge surfaces and opposed side surfaces, wherein the opposed edge surfaces undulate with crests and troughs;
- ii) a substantially flat strip having an inner surface and an opposed outer surface;
- iii) a first adhesive adhering the inner surface of the substantially flat strip to the crests of one of the opposed edge surfaces of the elongated strip;
- iv) a second adhesive adhering the outer surface of the substantially flat strip to a fiber reinforced polymer having a top surface and opposed side surfaces, the fiber reinforced polymer shaped to cover the outer surface of the substantially flat strip and the opposed side surfaces of the elongated strip;
- and
- v) an activatable sealant on each of the opposed side surfaces of the fiber reinforced polymer.
