Abstract

Various embodiments of the disclosure are directed towards fenestration assemblies having a first pane; a second pane, the second pane spaced from the first pane; and a third pane configured in spaced relation between the first pane and the second pane, where the third pane is a laminate. In one aspect, the total thickness of the third pane laminate is not greater than 3 mm. In one aspect, the laminate comprises a first glass layer not greater than 1 mm thick and a second glass layer not greater than 1 mm thick, and an interlayer between first and second layers.

Claims (42)

1. A fenestration assembly, comprising:

a first pane;

a second pane, the second pane configured in a spaced relation with the first pane; and

a third pane configured in spaced relation between the first pane and the second pane, the third pane comprises a laminate, wherein the laminate thickness is less than 4.3 mm,

wherein the laminate comprises:

a first glass layer having a thickness of not greater than 1 mm;

a second glass layer having a thickness of not greater than 1 mm; and

an interlayer configured between the first and second layer.

2. The fenestration assembly of claim 1 , wherein the laminate thickness is less than 3 mm.

3. The fenestration assembly of claim 1 , wherein the laminate comprises a low emissivity coating on at least one of: a first major surface of the first glass layer, a second major surface of the second glass layer, and combinations thereof.

4. The fenestration assembly of claim 1 , wherein at least one of the first glass layer and the second glass layer of the laminate has a low coefficient of thermal expansion (CTE).

5. The fenestration assembly of claim 4 , wherein the first glass layer and the second glass layer of the laminate have a coefficient of thermal expansion less than 7×10 −6 /K.

6. The fenestration assembly of claim 1 , wherein the first glass layer and second glass layer of the laminate comprise:

a. a soda lime silicate glass;

b. alumina borosilicate glass;

c. an alkali-aluminosilicate glass

d. an alkaline earth boro-aluminosilicate glass; or

e. an alkali-free boro-aluminosilicate glass.

7. The fenestration assembly of claim 6 , wherein the first glass layer comprises a soda lime silicate glass layer and the second glass layer comprises an alumina borosilicate glass layer.

8. The fenestration assembly of claim 1 , wherein the thickness of the fenestration assembly is not greater than 35 mm.

9. The fenestration assembly of claim 1 , wherein the fenestration assembly further comprises an insulating glass unit (IGU).

10. The fenestration assembly of claim 1 , further comprising a window, a door, a skylight, a curtain wall, and/or combinations thereof.

11. The fenestration assembly of claim 1 , wherein the first pane and second pane are selected from the types of glass consisting of:

a. a soda lime silicate glass;

b. alumina borosilicate glass;

c. alkali-aluminosilicate glass

d. an alkaline earth boro-aluminosilicate glass; and

e. an alkali-free boro-aluminosilicate glass.

12. The fenestration assembly of claim 1 , wherein the first pane and the second pane are composed of the same type of glass.

13. The fenestration assembly of claim 1 , wherein the first pane and the second pane are composed of different types of glass.

14. The fenestration assembly of claim 1 , further comprising a low emissivity coating on the first surface of the first pane.

15. The fenestration assembly of claim 1 , wherein the interlayer comprises a polymer.

16. The fenestration assembly of claim 1 , wherein the interlayer is an acoustic dampening polymer configured for noise reduction.

17. The fenestration assembly of claim 1 , wherein the interlayer is a tinted polymer configured for light absorption.

18. The fenestration assembly of claim 1 , further comprising:

a first defined gap between the first pane and the third pane; and

a second defined gap between the second pane and the third pane.

19. The fenestration assembly of claim 1 , wherein the first defined gap and the second defined gap are filled with non-reactive gas.

20. The fenestration assembly of claim 1 , wherein the fenestration assembly passes a safety test as set out in at least one of: ANSI Z97.1 and EN 12600 standard, when measured in accordance with the standard.

21. The fenestration assembly of claim 1 , wherein the fenestration assembly comprises a weighted noise reduction metric R w of at least 35 dB, when measured in accordance with ISO 717-1 standard.

22. The fenestration assembly of claim 1 , wherein the interlayer of the third pane is not greater than 2.3 mm.

23. The fenestration assembly of claim 1 , wherein the laminate thickness is greater than 2 mm.
