Glass block with low-e center lite
View Patent ↗A glass block assembly ( 2 ) includes first ( 4 ) and second ( 6 ) glass block halves. A spacer ( 8 ) is disposed between the glass block halves to thermally isolate the first glass block half from the second glass block half. A sealant extends from the outer surface of the first glass block half over the spacer to the outer surface of the second glass block half to hermetically seal the internal chamber of the assembly. The spacer has a pair of legs ( 24 ) extending laterally outwardly from the body to define shoulders that engage the inner surfaces of the first and second halves. The legs of the spacer define a slot ( 25 ). An interior lite ( 10 ) is carried by the spacer in the interior chamber.
1. A glass block assembly; comprising:
first and second glass block portions; each glass block portion having a sidewall and an outer face; the sidewalls having inner surfaces and outer surfaces; the glass block portions facing each other to define an internal chamber;
a spacer disposed between the glass block portions to thermally isolate the first glass block portion from the second glass block portion;
the spacer including a body disposed directly between the sidewalls of the glass block portions;
a sealant extending between the spacer and the glass block to hermetically seal the internal chamber;
the spacer having a pair of legs extending laterally outwardly from the body to define shoulders that engage the inner surfaces of the first and second glass block portions;
the legs of the spacer defining a slot; and
an interior lite disposed in the interior chamber; the interior lite being carried by the spacer.
2. The assembly of claim 1 , wherein the sidewalls of the first and second glass block portions are adhesively connected to the body of the spacer.
3. The assembly of claim 1 , further comprising an adhesive disposed in the slot to secure the lite in the slot.
4. The assembly of claim 1 , wherein the interior lite is low-e coated.
5. The assembly of claim 1 , wherein the entire slot is defined by the legs of the spacer with no portion of the slot of the spacer disposed directly between the sidewalls of the first and second glass block portions.
6. The assembly of claim 1 , wherein the spacer includes a head that projects outwardly from the outer surfaces of the first and second glass block portions.
7. The assembly of claim 1 , wherein a portion of the slot is defined by the body of the spacer and is directly disposed between the sidewalls of the first and second portions.
8. The assembly of claim 1 , further comprising fingers extending from the spacer into the slot.
9. The assembly of claim 8 , wherein the fingers are angled toward an end of the slot.
10. The assembly of claim 1 , further comprising arms that extend outwardly from the legs of the spacer; the arms being positioned along the inner surfaces of the first and second glass block portions.
11. The assembly of claim 1 , wherein each of the first and second glass block portions includes a lip projecting outwardly at the corner defined by the sidewall and the front face; the sealant extending from the lip of the first glass block portion to the lip of the second glass block portion.
12. The assembly of claim 1 , wherein the sealant is in the form of an adhesive tape having an inner sealant layer and an outer body layer.
13. The assembly of claim 12 , wherein the outer body layer is waterproof.
14. The assembly of claim 1 , wherein the outer surfaces of the first and second glass block portions are painted.
15. The assembly of claim 1 , wherein the spacer is flexible.
16. The assembly of claim 15 , wherein the spacer carries a desiccant.
17. The assembly of claim 15 , wherein the spacer is silicone.
18. A glass block assembly; comprising:
first and second glass block portions; each glass block member having a sidewall and an outer face; the sidewalls having inner surfaces and outer surfaces; the glass block portions facing each other to define an internal chamber;
a spacer disposed between the glass block portions to thermally isolate the first glass block member from the second glass block member;
the spacer including a body disposed directly between the sidewalls of the glass block portions;
a sealant extending between the spacer and the glass block to hermetically seal the internal chamber;
the spacer having a pair of legs extending laterally outwardly from the body to define shoulders that engage the inner surfaces of the first and second glass block portions; and
an interior lite disposed in the interior chamber; the interior lite being carried by the spacer and engaging at least one of the legs of the spacer.
19. The assembly of claim 18 , wherein the spacer includes a pair of arms that extend along the inner surfaces of the sidewalls of the glass block portions.
20. The assembly of claim 18 , wherein the sidewalls of the first and second glass block portions are adhesively connected to the body of the spacer.
21. The assembly of claim 18 , wherein a slot is defined by the legs of the spacer with no portion of the slot of the spacer disposed directly between the sidewalls of the first and second glass block portions.
22. The assembly of claim 18 , wherein the spacer includes a head that projects outwardly from the outer surfaces of the first and second glass block portions.
