LuxHeat Cable Fixing Strips for Radiant Floor Heating Cables
LuxHeat floor heating strips are cable fixing guides designed to hold radiant floor heating cables in precisely consistent spacing throughout your installation. One of the most common sources of uneven heat distribution in a radiant system is cables that shift or drift during the mortar or thinset pour — these heated floor strips eliminate that problem entirely by locking every cable into place at controlled intervals from the very start.
Each strip features lugs spaced every 1 inch, giving you full control over cable spacing across any layout — straight runs, curves, and custom configurations alike. The easy-to-cut design lets you trim the strip to any length on site, and it fastens directly to both timber and concrete subfloors. Whether you are working in a compact bathroom or a large open-plan space, the 1-inch lug increments let you hit any recommended cable spacing without improvising.
Sold in 25 ft and 75 ft lengths, these radiant heat strips are the dedicated fixing solution for LuxHeat loose-lay heating cables and are compatible with most electric floor heating cable systems. Using fixing strips instead of tape or wire ties keeps your layout consistent, protects the cable jacket during installation, and helps ensure the system heats evenly from edge to edge when switched on.

Frequently Asked Questions
How far apart should I space my radiant floor heating cables using these fixing strips?
For LuxHeat loose-lay cables, 3-inch spacing is the standard recommended spacing, delivering approximately 12 W/sq ft for even, efficient heat distribution. Cables can be spaced wider — for example at 4 inches — but this will reduce output and may result in uneven heat distribution across the floor.
Cables can also be spaced more tightly using an alternating 2-3-2 pattern, but should not be spaced closer than this. The fixing strips' 1-inch lug spacing lets you hit any of these increments precisely. If you're unsure about the right layout for your project, ProLux Materials' free Design & Layout Service will provide a custom cable layout plan.
Do the fixing strips come with fasteners to attach them to the subfloor?
No — fasteners are not included. For concrete subfloors, most installers use a powder-actuated tool or concrete nails; for timber subfloors, standard staples or construction nails work well. The strips are designed to accept most common fastener types.
