Abstract

An underlayment system is provided that includes a plurality of protrusions that extend from a common base member. The protrusions and base member can include an opening therethrough that allows for subsequent layers of material, such as adhesive, to interact and bond to each other. The protrusions are arranged in such a way to contain a wire, string, or heating element, within a receiving area. The arrangement of the protrusions allow for routing of the wire, string, or heating element in a variety of angles, bends, and other routing layouts.

First claim

What is claimed is:

1. An underlayment adapted to receive and secure at least one heating element of a radiant heating assembly, comprising:
a base material defining an area and having a first side and a second side disposed opposite the first side;
a plurality of routing hubs disposed on the first side of the base material, the routing hubs having a substantially circular perimeter and being equally spaced from each other in rows and columns, each routing hub comprising:
a first protrusion configured as a geometric shape having an upper surface substantially parallel to the first side of the base material and extending between an element receiving surface and an inner side surface, the inner side surface sloping continuously toward a center point of the routing hub from the upper surface to the first side, and the element receiving surface sloping underneath the upper surface; and
a second protrusion adjacent to the first protrusion, the second protrusion configured as a geometric shape having an upper surface substantially parallel to the first side of the base material and extending between an element receiving surface and an inner side surface, the inner side surface sloping continuously toward a center point of the routing hub from the upper surface to the first side, and the element receiving surface sloping underneath the upper surface,
wherein the element receiving surfaces of the first protrusion and of the second protrusion define portions of the substantially circular perimeter, and the inner side surfaces of the first protrusion and of the second protrusion face each other on opposite sides of a channel separating the first protrusion and the second protrusion.

2. The underlayment of claim 1 , wherein adjacent ones of the plurality of routing hubs form an element receiving cavity therebetween, the element receiving cavity configured to contain at least one heating element of the radiant heating assembly.

3. The underlayment of claim 2 , wherein each routing hub comprises at least four protrusions equally-spaced in a circular array about an array axis extending through the center point of the routing hub.

4. The underlayment of claim 1 , wherein the first protrusion and the second protrusion further have at least one cutout portion.

5. The underlayment of claim 4 , wherein the cutout portions are adapted to receive one of at least adhesive, epoxy, grout, cement, glue, and plastic.

6. The underlayment of claim 1 , wherein the routing element receiving cavity has a maximum width at a first height above the first side and a narrower width at a second height above the first side, the second height greater than the first height.

7. The underlayment of claim 1 , wherein the first protrusion and the second protrusion are formed from the base material.

8. A floor assembly, comprising;
an underlayment layer comprising:
a base material defining an area and having a first side and a second side disposed opposite the first side,
a plurality of routing hubs separated from each other by a plurality of element receiving cavities, each routing hub comprising:
a first protrusion disposed on the first side of the base material, the first protrusion configured as a geometric shape having an upper surface substantially parallel to the first side of the base material and extending between an arcuate element receiving surface defining a portion of a first one of the plurality of element receiving cavities and an arcuate inner surface, the arcuate inner surface sloping continuously toward a center point of the routing hub, and the arcuate element receiving surface sloping underneath the upper surface; and
a second protrusion disposed on the first side of the base material and adjacent to the first protrusion, the second protrusion configured as a geometric shape having an upper surface substantially parallel to the first side of the base material and extending between an arcuate element receiving surface defining a portion of a second one of the plurality of element receiving cavities and an arcuate inner surface, the arcuate inner surface sloping continuously toward a center point of the routing hub, the arcuate element receiving surface sloping underneath the upper surface,
wherein the first protrusion is spaced from the second protrusion by a channel, the channel at least partially defined by the arcuate inner surface of the first protrusion and the arcuate inner surface of the second protrusion; and

a heating element contained within at least one of the plurality of element receiving cavities.

9. The floor assembly of claim 8 , further comprising:
a pad layer, wherein the pad layer is attached to the base layer.

10. The floor assembly of claim 9 , wherein the pad layer is attached to the base layer by at least one of adhesive, thermal bonding, welding, and mechanical attachment.

11. The floor assembly of claim 8 , wherein the heating member is one of a wire and a fluid conduit.

12. The floor assembly of claim 9 , wherein the pad layer is at least one of foil, cork, rubber, plastic, concrete, wood, organic materials, inorganic materials, composites, and compounds.

13. The floor assembly of claim 9 , further comprising a sub floor, wherein the sub floor is attached to a bottom side of the pad layer.

14. An underlayment adapted to receive and secure at least one heating element of a radiant heating assembly, comprising:
a base material defining an area and having a first side and a second side disposed opposite the first side;
a plurality of routing hubs disposed on the first side of the base material in a plurality of rows and columns, with a routing hub positioned at each intersection of a row of routing hubs and a column of routing hubs, each of the routing hubs comprising a plurality of protrusions and having a substantially circular perimeter defined by an outer surface of each of the plurality of protrusions, the substantially circular perimeter having a plurality of gaps therein; and
a heating element receiving cavity formed between at least two of the routing hubs, the heating element receiving cavity adapted to receive a heating element;
wherein each of the plurality of gaps corresponds to a space between two of the plurality of protrusions, and
wherein each of the plurality of protrusions comprises an upper surface substantially parallel to the first side of the base material, a first side surface proximate an adjacent routing hub and sloping underneath the upper surface, and a second side surface sloping continuously toward a center point of the routing hub from the upper surface to the first side and facing another one of the plurality of protrusions.

15. The underlayment of claim 14 , wherein each of the plurality of protrusions has at least one cutout portion.

16. The underlayment of claim 15 , wherein the cutout portions are adapted to receive one of at least adhesive, epoxy, grout, cement, glue, and plastic.

17. The underlayment of claim 14 , wherein each of the plurality of protrusions is formed from the base material.

18. The underlayment of claim 14 , wherein each routing hub comprises four protrusions equally spaced about an array axis extending through the center point of the routing hub.

19. The underlayment of claim 14 , wherein the first side surface defines a portion of the heating element receiving cavity and comprises a receiving surface adapted to retain a heating element.

20. The underlayment of claim 19 , wherein the receiving surface is one of an arcuate receiving surface and an angu
