Abstract
An underlayment system is provided that includes a plurality of bosses that emanate from 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.
Claims20
A floor underlayment comprising:
- a base having a bottom side and a top side;
- and
- a plurality of bosses extending above the top side, each boss of the plurality of bosses comprising:
- a circular inner wall;
- an outer wall surrounding the circular inner wall;
- and
- an upper surface extending between the outer wall and the circular inner wall so as to form an enclosure filled with air,
- wherein the outer wall extends from the upper surface to the base, the circular inner wall extends from the upper surface to the base, a portion of the base extends inward toward a center of the boss from the inner wall, and a first horizontal distance between at least a portion of the outer wall and an adjacent portion of the circular inner wall at a height proximate the upper surface is greater than a second horizontal distance between the at least a portion of the outer wall and the adjacent portion of the circular inner wall at a height proximate the base.

An underlayment comprising:
- a base having a bottom side and a top side;
- a heat reflective layer on the bottom side of the base;
- and
- a plurality of bosses formed integrally with and extending from the top side of the base, each boss of the plurality of bosses comprising:
- a rounded inner wall;
- a rounded outer wall surrounding the rounded inner wall;
- and
- an upper surface connecting the rounded outer wall to the rounded inner wall,
- wherein the upper surface, the rounded outer wall, and the rounded inner wall at least partially define a volume filled with air, the rounded inner wall extends from the upper surface to the base, a portion of the base extending inward from the rounded inner wall toward a center of the boss, and a first horizontal distance between a segment of the rounded outer wall and an adjacent segment of the rounded inner wall at a height proximate the upper surface is greater than a second horizontal distance between the segment of the rounded outer wall and the adjacent segment of the rounded inner wall at a height proximate the base.

An underlayment comprising:
- a base having a top side and a bottom side;
- and
- a matrix of bosses on the top side of the base, each boss in the matrix of bosses comprising:
- a top surface;
- a circular inner wall extending from the top surface to the base;
- and
- a sloping outer wall extending from the top surface to the base, the sloping outer wall extending underneath the top surface,
- wherein the top surface, the circular inner wall, and the sloping outer wall form a hollow enclosure, a portion of the base extends from the circular inner wall toward a center of the boss, the sloping outer wall has a variable slope, and a first horizontal distance between at least a segment of the sloping outer wall and an adjacent segment of the circular inner wall at a height proximate the top surface is greater than a second horizontal distance between the at least a segment of the sloping outer wall and the adjacent segment of the circular inner wall at a height proximate the base.
