Abstract

A fire resistant construction block that comprises a core comprising a polygonal shape including a front face, a rear face, a right face, a left face, a bottom face, and a top face. The fire resistant construction block further comprises a fire resistant coating surrounding at least a portion of the core and an optional intermediate layer disposed between the core and the fire resistant coating. The fire resistant construction block can comprise a plurality of channels, and the top face of the fire resistant construction block comprises a sloped surface. The fire resistant construction block can be configured to be disposed above a window of a building and the placement of the fire resistant construction block can enable an exterior wall of a building to comply with a National Fire Protection Agency Code 285 standard fire test method and/or other fire test standards.

Claims (32)

1. A wall system, comprising:

a fire resistant construction block disposed above a window, the fire resistant construction block comprising:

a front face, a rear face, a right face, a left face, a bottom face, and a top face;

wherein an outer surface of the fire resistant construction block is fire resistant; and

wherein the top face comprises a sloped surface;

a panel disposed above the fire resistant construction block; and

a covering attached to at least one of the front face of the fire resistant construction block or a front face of the panel.

2. The wall system of claim 1 , wherein the fire resistant construction block comprises a plurality of channels that extend vertically in the rear face of the fire resistant construction block and horizontally in the bottom face of the fire resistant construction block.

3. The wall system of claim 1 , wherein a length of the fire resistant construction block corresponds with a length of the window and opposing edges of the fire resistant construction block correspond with opposing edges of the window.

4. The wall system of claim 1 , wherein a length of the fire resistant construction block exceeds a length of the window and opposing edges of the fire resistant construction block extend beyond opposing edges of the window.

5. The wall system of claim 1 , wherein the covering further comprises a plurality of wall coverings that are attached to the front face of the fire resistant construction block and the front face of the panel.

6. The wall system of claim 1 , wherein placement of the fire resistant construction block enables an exterior wall of a building to comply with at least one of National Fire Protection Agency Code 285 standard fire test method (2018) or National Fire Protection Agency Code 285 standard fire test method (2019).

7. The wall system of claim 1 , further comprising a flashing disposed between the window and the fire resistant construction block.

8. The wall system of claim 7 , wherein the flashing is sloped at an angle, and wherein the angle is between 0 degrees and 5 degrees and extends beyond the fire resistant construction block.

9. The wall system of claim 1 , wherein the fire resistant construction block comprises a fire first resistant coating surrounding at least a portion of a core.

10. The wall system of claim 9 , wherein the core comprises polystyrene or polyisocyanurate.

11. A method of attaching a wall system to a building, comprising:

attaching a fire resistant construction block to a substrate of the building above a window of the building, the fire resistant construction block comprising:

a front face, a rear face, a right face, a left face, a bottom face, and a top face;

wherein an outer surface of the fire resistant construction block is fire resistant; and

wherein the top face comprises a sloped surface;

attaching a panel to the substrate of the building above the fire resistant construction block; and

attaching a covering to at least one of the fire resistant construction block or the panel.

12. The method of claim 11 , wherein the fire resistant construction block comprises a plurality of channels that extend vertically in the rear face of the fire resistant construction block and horizontally in the bottom face of the fire resistant construction block.

13. The method of claim 11 , wherein a length of the fire resistant construction block corresponds with a length of the window and opposing edges of the fire resistant construction block correspond with opposing edges of the window.

14. The method of claim 11 , wherein a length of the fire resistant construction block exceeds a length of the window and opposing edges of the fire resistant construction block extend beyond opposing edges of the window.

15. The method of claim 11 , wherein the covering further comprises a plurality of wall coverings that are attached to the front face of the fire resistant construction block and a front face of the panel.

16. The method of claim 11 , wherein placement of the fire resistant construction block enables an exterior wall of the building to comply with at least one of National Fire Protection Agency Code 285 standard fire test method (2018) or National Fire Protection Agency Code 285 standard fire test method (2019).

17. The method of claim 11 , further comprising a flashing disposed between the window and the fire resistant construction block.

18. The method of claim 17 , wherein the flashing is sloped at an angle, and wherein the angle is between 0 degrees and 5 degrees and extends beyond the fire resistant construction block.

19. The method of claim 11 , wherein the fire resistant construction block comprises a fire resistant coating surrounding a core.

20. The method of claim 19 , wherein the core comprises polystyrene or polyisocyanurate.
