Perfect for refurbishments
Nexxa 12 is a low profile castellated underfloor heating system, designed for refurbishment projects where low floor buildup is required. The system incorporates a 12mm PERT pipe within a plastic castellated panel, which is then covered with a 22mm layer of appropriate levelling compound. Nexxa 12 bonds directly to a smoothed and primed subfloor.
With fast response times and excellent heat output (70W/m2 for timber floors at 40°C water temperature), Nexxa 12 is a great way to bring the warmth and luxury of underfloor heating to your project.
Quick and easy to install
The Nexxa 12 panels are self-adhesive, making them quick to lay with no waiting around for drying time. Once laid, the 12mm pipe can be simply clipped into place to cover the required heated area, in either square patterns or diagonals, to suit the space.
The panels are easy to cut with a utility knife and measure 650 x 1050mm. Once the pipe is installed, an appropriate levelling compound can be poured to a thickness of 22mm. Insulation should be installed underneath the Nexxa 12 panels to ensure rapid heat up times and reduce energy usage.
Use with Warmup Primer
Warmup Primer is a ready to use, bond enhancing and solvent-free single component primer for the preparation of absorbent and non-absorbent floors and walls with or without surface heating. Ideal for use before laying Warmup Peel and Stick systems, levelling compounds and tile adhesives. Suitable for use as a deep penetrating primer on absorbent surfaces.
