Abstract

Fireplaces including antireflective screens are provided. The antireflective screens can include a glass sheet with an antireflective agent attached to or forming a surface of at least a portion of the glass sheet. A low-emissivity agent can also be attached to or form a surface of at least a portion of the glass. In addition, light diffusing screens for displaying simulated flames in simulated fireplaces are provided. The light diffusing screens can include an antireflective agent attached to or forming a surface of at least a portion of the light diffusing screens.

Claims

1. A fireplace assembly, comprising:

a firebox, wherein said firebox defines a firebox interior and an opening to the firebox interior;

a substantially transparent screen disposed in said opening, wherein said screen includes a first side and a second side opposite said first side; and

an anti-reflective agent attached to or forming a surface of at least a side portion of one or both of said first side and said second side of said transparent screen.

2. The fireplace assembly of claim 1, wherein said anti-reflective agent includes magnesium fluoride.

3. The fireplace assembly of claim 1, wherein said anti-reflective agent includes silicone dioxide.

4. The fireplace assembly of claim 1, wherein said anti-reflective agent is sputter coated onto said transparent screen.

5. The fireplace assembly of claim 1, wherein said anti-reflective agent is dip coated onto said transparent screen.

6. The fireplace assembly of claim 1, wherein said anti-reflective agent is sprayed onto said transparent screen.

7. The fireplace assembly of claim 1, wherein said anti-reflective agent is attached to or forms a surface of all of said first side.

8. The fireplace assembly of claim 1, wherein said anti-reflective agent is attached to or forms a surface of a portion of said first side.

9. The fireplace assembly of claim 1, wherein said anti-reflective agent is attached to or forms a surface of at least a portion of said first side and is attached to or forms a surface of at least a portion of said second side.

10. The fireplace assembly of claim 1, further including a layer of silicon dioxide attached to or forming a surface of said transparent screen over said anti-reflective agent.

11. The fireplace assembly of claim 1, wherein said anti-reflective agent includes a plurality of anti-reflective agents.

12. The fireplace assembly of claim 11, wherein said plurality of anti-reflective agents includes a layer of magnesium fluoride and a layer of silicone dioxide.

13. The fireplace assembly of claim 1, further including a low-emissivity agent attached to or forming a surface of said second side of said transparent screen.

14. The fireplace assembly of claim 13, wherein said low-emissivity agent is a layer of tin oxide.

15. The fireplace assembly of claim 11, further comprising an inside layer of anti-reflective agent attached to or forming a surface of said second side of said transparent screen and a low-emissivity agent attached to or forming a surface of said inside layer of anti-reflective agent.

16. The fireplace assembly of claim 11, further comprising a low-emissivity agent attached to or forming a surface of said second side of said transparent screen and an inside layer of anti-reflective agent attached to or forming a surface of said inside layer of low-emissivity agent.

17. The fireplace assembly of claim 1, wherein said firebox includes a top wall, a bottom wall, a back wall, and two side walls

18. A light-diffusing screen for displaying a simulated flame in a simulated fireplace having a flame-simulating assembly, comprising:

a light-transmitting member having a first side and an opposed second side; and

an antireflective agent attached to or forming a surface of at least a portion of said first side of said light-transmitting member.

19. The light-diffusing screen of claim 18, further including a light-diffusing agent attached to or forming a surface of said second side of said light-transmitting member.

20. The light-diffusing screen of claim 18, wherein said light-transmitting member is transparent.

21. The light-diffusing screen of claim 18, wherein said light-transmitting member is translucent.

22. The light-diffusing screen of claim 19, wherein the light-diffusing agent includes a light-diffusing ink.

23. The light-diffusing screen of claim 19, wherein the light-diffusing agent is attached to or forms a surface of all or a portion of said second side of said light-transmitting member.

24. The light-diffusing screen of claim 18, wherein said anti-reflective agent is magnesium fluoride.

25. The light-diffusing screen of claim 18, wherein said anti-reflective agent is silicone dioxide.
