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.

The invention provides a surface covering product, in particular a floor covering product, comprising boundary walls defining a lower face which in use faces a surface to be covered, said boundary walls having an upper face extending up to 60 cm from said lower face, said boundary walls dividing a part of said surface to be covered into at least partially enclosed surface parts and providing a boundary for at least one filling composition in said at least partially enclosed surface parts, wherein said surface covering product further comprises a base web having said boundary walls coupled to said base web for holding said boundary walls in position, and said base web comprises an upper surface below said upper face of said boundary walls, and a lower surface which in use rests on said surface to be covered, said boundary walls are coupled on top of said base web, and in use said filling composition covers said base web and at least part of said boundary walls, and wherein at least said boundary walls are formed in a three-dimensional (3D) printing process.

A heat module for a flooring. The heat module has a stepping plate having a first side and a second side, at least one heat element arranged along the first side of the stepping plate, and a water impermeable insulator at the first side of the stepping plate. The at least one heat element is attached to the first side of the stepping plate so that emitted heat is directly conducted to the stepping plate.

Provided is a self-assembly hot water mat capable of extending through assembly. A self-assembly hot water mat capable of being assembled with other self-assembly hot water mats, having four sides, and including a path for circulating hot water includes a plurality of hot water passages formed in the self-assembly hot water mat to provide a plurality of hot water flow paths, an inlet formed at each of the four sides, through which hot water flows in, and an outlet formed at each of the four sides and paired with the inlet, through which hot water flows out.

A floor panel having a heating element disposed therein, the floor panel having at least two abutments for operationally coupling the panel to adjacent panels. Electrical contacts are disposed on complementary abutments or abutment walls and busbars electrically couple between complementary contacts of opposing abutments such that, when adjacent floor panels are laid together to form a floor or a portion thereof, the busbars are able to feed power to heating elements disposed in the panel. The panel have sealants and/or adhesives which protect at least one contact from fluids. Also disclosed are connector bars, adapters, and switching and protection arrangements, and optional constructions for inter-panel connectors.

A heating system including a carbon veil heating element having at least two busbars embedded between opposite layers of insulating film, a connector busbar assembly having at least two connector electrical busbars and a matrix of insulation connecting them, penetrating conductive fasteners configured to protrude through the respective busbars of the heating element and the connector busbar assembly, and a controller configured to connect to the connector busbars and apply electrical current sufficient to cause the heating element to produce heat between the veil busbars. The busbars preferably have a width to thickness ratio greater than 10, more preferably greater than 100. Methods for installing the heating system are also described.

Some deck or patio areas constructed of payers mourned on adjustable pedestal supports must remain snow and ice free on their top surfaces. The pedestal-mounted paver heating system is designed to allow easy installation of electric heating cable that is positioned against the bottom surface of pavers so that heat generated by the cable is efficiently transferred up into the payers to raise their temperature enough to prevent the accumulation of snow and ice on their top surfaces.

A system for mounting wall panels to a wall includes wall panels, each including a main wall panel section, and four bent end sections extending from edges of the main wall panel section; a plurality of main fastening extrusions, each including a base secured to the wall, two spaced apart post walls extending from the base section, and two bent end securing walls extending from the base on opposite sides of each post wall, with a spacing between each post wall and an adjacent bent end securing wall being equal to the wall thickness of one bent end section; and a recess at a first surface of each bent end section which faces a second surface of a respective bent end securing wall, and a projection at the second surface of each bent end securing wall which is adapted to be received in a respective recess.

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.

Disclosed is a studded membrane for underfloor heating, of the detaching membrane type which also acts as a support for the laying of electrical conductors. The studded membrane has one waterproof plastic sheet coupled to one base layer for anchoring the membrane on the laying plane, with studs which protrude from the membrane-plane and are arranged in a matrix with regular center to center distance in such a way to obtain hollow and continuous spaces among them in the form of corridors. A heating cable is retained and placed among the studs. In particular, adhesive curbs are provided to retain the heating cable and are made up of a glue laid in strips on the membrane-plane, in correspondence with the corridors among the studs acting as laying corridors for the glue.
