Abstract

A window system includes a frame, a glazing assembly held within the frame and including a glass stop attachable to the frame, wherein attaching the glass stop to the frame defines an air pocket between the glass stop and the frame, and a thermal dampening device positioned within the air pocket and defining one or more discrete cavities.

First claim

What is claimed is:

1. A window system, comprising:
a frame;
a glazing assembly held within the frame and including:
an infill; and
a glass stop having a glass stop base extending laterally from the infill and one or more legs extending from the glass stop base and attachable to the frame, wherein attaching the one or more legs to the frame defines an air pocket between the glass stop and the frame; and

a thermal dampening device positioned within the air pocket and engageable with the glass stop base, the thermal dampening device providing a base and a plurality of fins that extend from the base and define one or more discrete cavities,
wherein the base is made of a rigid material and the plurality of fins are made of a flexible material different from the rigid material.

2. The window system of claim 1 , wherein the frame includes a head, a sill, and opposing left and right vertical jambs extending between the head and the sill, and wherein the glass stop is attachable to any one of the head, the sill, and the opposing left and right vertical jambs.

3. The window system of claim 1 , wherein the base is removably attached to the glass stop base.

4. The window system of claim 3 , wherein at least one of the plurality of fins extends to and engages the frame.

5. The window system of claim 4 , further comprising a thermal break mounted to the frame, wherein at least one of the plurality of fins contacts the thermal break.

6. The window system of claim 1 , wherein the base and the plurality of fins are made of a thermoplastic polymer.

7. The window system of claim 1 , wherein the thermal dampening device extends between and contacts the glass stop and the frame.

8. The window system of claim 7 , wherein the thermal dampening device provides multiple structural members that cooperatively define the one or more discrete cavities.

9. The window system of claim 7 , wherein at least a portion of the thermal dampening device is made of an elastomer to seal an interface between the frame and the thermal dampening device.

10. The window system of claim 1 , wherein the plurality of fins is made of flexible material that dynamically conforms to a shape of the air pocket.

11. A method of reducing thermal transmission through a window system, comprising:
positioning a thermal dampening device within an air pocket defined between a glazing assembly and a frame of the window system, the thermal dampening device providing a base and a plurality of fins that extend from the base and define one or more discrete cavities, the glazing assembly including:
an infill; and
a glass stop having a glass stop base extending laterally from the infill and one or more legs extending from the glass stop base and attached to the frame, wherein attaching the one or more legs to the frame defines the air pocket between the glass stop and the frame, and wherein the thermal dampening device is positioned within the air pocket and engageable with the glass stop base; and

reducing thermal transmission through the air pocket with the thermal dampening device,
wherein the base is made of a rigid material and the plurality of fins are made of a flexible material different from the rigid material.

12. The method of claim 11 , further comprising reducing convective heat transfer through the air pocket with the one or more discrete cavities.

13. The method of claim 11 , wherein the thermal dampening device extends between and contacts the glass stop and the frame, the method further comprising reinforcing the glass stop with the thermal dampening device.

14. The method of claim 11 , wherein at least a portion of the thermal dampening device is made of an elastomer, the method further comprising sealing an interface between the frame and the thermal dampening device with the thermal dampening device.

15. A method of retrofitting a window system, comprising:
removing a glass stop from a glazing assembly held within a frame of the window system, the glass stop having a glass stop base extending laterally from an infill of the glazing assembly and one or more legs extending from the glass stop base and attachable to the frame, wherein attaching the one or more legs to the frame defines an air pocket between the glass stop and the frame;
arranging a thermal dampening device such that it is positioned within the air pocket when the glass stop is attached to the frame, the thermal dampening device providing a base and a plurality of fins that extend from the base and define one or more discrete cavities, wherein the base is made of a rigid material and the plurality of fins are made of a flexible material different from the rigid material; and
reattaching the glass stop to the frame, wherein the thermal dampening device engages the glass stop base.

16. The method of claim 15 , wherein the thermal dampening device extends between and contacts the glass stop and the frame, the method further comprising reinforcing the glass stop with the thermal dampening device.

17. The method of claim 15 , wherein arranging the thermal dampening device comprises removably attaching the thermal dampening device to the glass stop.

18. The method of claim 15 , wherein at least a portion of the thermal dampening device is made of an elastomer, the method further comprising sealing an interface between the frame and the thermal dampening device with the thermal dampening device.
