In-slab Cable System

Heatup In-Slab Cable is made to be used inside of a concrete floor construction.
Price Starting at $4.67 per square foot.

For what kind of project was In-Slab cable intended?

The In-Slab Cable System is intended for use in situations where concrete floors need underfloor heating. In-slab floor heating system is particularly well suited for concrete floor constructions in new construction where the floor height is not a concern. MEM-PRO system might be a better option for retrofit in existing concrete floors when there is less room to change the floor height.

A concrete screed with 2 to 6 inches of thickness can be installed with the In-Slab Cable electric underfloor heating system. For the fastest heat-up times, insulation boards must be utilized if there is no insulation or if there are more than 4 inches of concrete subflooring underneath.

The In-Slab Heater can be used with practically any type of flooring finish, especially if the flooring (such as wood, carpet, or vinyl) is subject to periodic replacement. The In-Slab Cable’s slower heat-up and cool-down times make them especially ideal for rooms that are in regular use because the slab can be used as a source of store heating.

Key Benefits

Floor coverings are interchangeable

Spend less money and enhance more flexibility without causing harm to the heater.

Maximum effect

Power output wire can be laid at various spacings to deliver the best output to match the flooring finish or room design.

Works under any floor finish

Any floor covering that is suitable for underfloor heating can be used with In-Slab Cable.

Floor Coverings That Are Appropriate for In-Slab Cable

In-Slab Cable can be used with virtually any type of flooring. There is less of a chance of damaging the heating cable if the floor covering is replaced on occasion because the heater is securely embedded in the cementitious slab. In-Slab Cable is compatible with the following flooring types:

 

Tiles

The In-Slab Cable electric underfloor heating system must be used in conjunction with flexible tile adhesive and grout if a tiled floor is being installed on top.

 

Laminate/Wood

In order to ensure that heat may transfer through laminate or engineered wooden board flooring, the thickness must not exceed 18mm. It must be feasible to install over an underfloor heating system if you use a layer of soft insulation underneath the flooring.

 

Carpet

Hessian-backed carpets must be used for carpeted floors, and the combined Tog rating of the carpet and underlay cannot be greater than 2.5 togs.

In-Slab Cable Underfloor Heating Installation on Concrete Floors

The installation documentation must be reviewed before beginning any installation. Applying insulation boards and laying the wire directly on them is advised if the subfloor is uninsulated or the concrete base is thicker than 4 inches. The wire can be installed into the concrete slab if it has a concrete base that is less than 4 inches thick or is insulated. While the second choice is fine, the system’s effectiveness will be increased by adding insulation to the area directly beneath the heating cable.

 

Make sure the subfloor is sturdy, made of a suitable material for a slab pour, and clear of dust and debris before you begin.

 

The In-Slab Cable ought to be installed inside the slab with a minimum depth of 2 inches and spacing of at least 2 inches. Metal fastening strips are required to fasten the In-Slab cable to the subfloor. To ensure there is no movement of the fixings, the metal fixing strips are always set out perpendicular to the heating element and secured to the insulation board or concrete floor using adhesive or fixing nails. The heating line is then strung across the room and secured with a metal fixing strip. Always space the cable appropriately to guarantee an even distribution of heat throughout the floor.

 

Cementitious material must be carefully poured over the fastened in In-Slab Cable to a depth of at least 2 inches in order to cover the heating system once the cable has been installed. As close as possible, embed the floor probe that came with the thermostat in the slab near the final floor finish. To complete the installation, connect a thermostat to the heating cable.

When the concrete or leveling compound has completely cured, you can put the final floor covering.
