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 boss disposed on the single base layer, the first boss comprising a first upper surface surrounding a first internal cavity having a curved surface; a second boss disposed on the single base layer and adjacent to the first boss, the second boss comprising a second upper surface surrounding a second internal cavity having a curved surface; wherein an upper portion of the first boss is closer to the second boss than a lower portion of the first boss.

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

3 . The radiant-heating system of claim 1 , wherein the first boss and second boss 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 boss is flexibly deflectable.

5 . The radiant-heating system of claim 1 , wherein at least one of the first boss and second boss is octagonal.

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 boss, and the second boss 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 boss and second boss are both ring shaped with a uniform height.

11 . A floor underlayment, comprising:
a base layer; a plurality of rows of bosses rising from the base layer, each boss comprising:
a curved outer wall surrounding an inner depression, the inner depression defined by a curved surface; and
an upper surface connecting the curved outer wall to the curved surface; and
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.

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 a plurality of in-floor heating elements, the system comprising:
an anti-fracture membrane; a 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 upper surface, an inner bowl, and an upper perimeter that is greater than a lower perimeter.

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.
