Abstract

An underlayment system is provided that includes a plurality of bosses that emanate form a common base member. The bosses and bases preferably include an opening therethrough that will allow for subsequent layers of adhesive to interact and bond to each other. The bosses are also spaced in such a way to help secure a wire snugly therebetween.

First claim

What is claimed is:

1. A radiant-heating system, comprising:
a single base layer;
a first protrusion disposed on the single base layer, the first protrusion comprising a first upper surface connecting a first inner wall and a first outer wall, the first inner wall spaced from the first outer wall, the single base layer extending from the first inner wall;
a second protrusion disposed on the single base layer and adjacent to the first protrusion, the second protrusion comprising a second upper surface connecting a second inner wall and a second outer wall, the second inner wall spaced from the second outer wall, the single base layer extending from the second inner wall; and
a heating element in contact with the single base layer, the first outer wall, and the second outer wall,
wherein each of the first inner wall, the first outer wall, the second inner wall, and the second outer wall is curved in a plane parallel to the single base layer; and
wherein an upper portion of the first protrusion is closer to the second protrusion than a lower portion of the first protrusion.

2. The radiant-heating system of claim 1 , wherein the upper portion of the first protrusion comprises an extension that extends in a direction parallel to the single base layer.

3. The radiant-heating system of claim 1 , wherein the first protrusion and second protrusion are spaced so as to receive a heating element therebetween.

4. The radiant-heating system of claim 1 , wherein the upper portion of the first protrusion is flexibly deflectable.

5. The radiant-heating system of claim 1 , wherein the upper surface of at least one of the first protrusion and the second protrusion comprises a plurality of holes.

6. The radiant-heating system of claim 1 , wherein the first upper surface is directly bonded to a flooring surface with thin set.

7. The radiant-heating system of claim 1 , wherein the single base layer comprises a plurality of holes therein.

8. The radiant-heating system of claim 1 , wherein the single base layer, the first protrusion, and the second protrusion are integrally formed, and further wherein the single base layer comprises an undersurface attached to an anti-fracture membrane.

9. The radiant-heating system of claim 8 , wherein the anti-fracture membrane is physically bonded to the single base layer.

10. The radiant-heating system of claim 1 , wherein the first protrusion and second protrusion are both ring shaped with a uniform height.

11. A floor underlayment, comprising:
a base layer having a plurality of holes therein;
a plurality of rows of bosses rising from the base layer, each boss comprising:
an outer wall spaced from an inner wall, each of the outer wall and the inner wall being curved in a plane parallel to the base layer, the base layer extending from the inner wall; and
an upper surface connecting the outer wall to the inner wall;
a corridor between each of the bosses in the plurality of rows of bosses, the corridor having a first width near the base layer and a second width above the base layer, wherein the first width is greater than the second width; and
a heating element in contact with the base layer and the outer wall of a plurality of bosses.

12. The floor underlayment of claim 11 , wherein a heating wire is disposed in at least one corridor.

13. The floor underlayment of claim 11 , wherein the base layer comprises an undersurface attached to an anti-fracture membrane.

14. The floor underlayment of claim 13 , wherein the anti-fracture membrane is physically bonded to the base layer.

15. The floor underlayment of claim 11 , wherein the upper surface is directly bonded to a flooring surface with thin set.

16. A system for securing an in-floor heating element, the system comprising:
an anti-fracture membrane;
a base layer having a plurality of holes therein, the base layer comprising an upper surface and a lower surface, the lower surface attached to the anti-fracture membrane;
a plurality of bosses protruding out of the upper surface away from the anti-fracture membrane, the plurality of bosses arranged in a matrix across the upper surface, each boss having an outer wall spaced from an inner wall, each of the outer wall and the inner wall being curved in a plane parallel to the base layer, the base layer extending from the inner wall; and
a heating element in contact with the base layer and the outer wall of at least two of the plurality of bosses.

17. The system of claim 16 , wherein the anti-fracture membrane is woven.

18. The system of claim 16 , wherein the anti-fracture membrane is physically bonded to the lower surface.

19. The system of claim 16 , wherein the anti-fracture membrane is removably attached to the lower surface.

20. The system of claim 16 , wherein the upper surface is directly bonded to a flooring surface with thin set.
