Application

Suitable to be laid directly under all types of flooring and over existing insulated flooring.

Description

Warmup Nexxa-12 is a lightweight and flexible self-adhesive underfloor heating installation system. Developed to secure 12 mm pipe for even temperature distribution, the system can be fitted by a single installer and allows for lateral and diagonal pipe spacing. The rigid and compact design ensures a low floor finish, making it ideal for retrofit or new home builds. Suitable to be laid below all flooring types, the panels require no overboarding whilst covering irregular surfaces better thanks to its flexibility.


Made from an environmentally friendly polystyrene that can be easily recycled in a carbon neutral factory, the panel can be cut to size and placed around existing obstacles due to its regular pipe spacing design. The panels are inter-locked to create a continuous layer across the floor ensuring a seemless flow of heat.


System build-up:

  • Warmup perimeter strip.
  • Floor finish.
  • 22 mm levelling compound.
  • Floor sensor.
  • Nexxa-12 membrane.
  • Warmup Ultralight (Optional).
  • Flexible tile adhesive (Optional).
  • Warmup primer.
  • Subfloor with a surface regularity of SR2.


Features and benefits:

  • Easy installation: Made from a environmentally friendly and recyclable polystyrene that can be installed easily and around existing objects. 
  • Excellent thermal properties: Excellent heat output when using low water temperatures alongside rapid response times to heating demand.
  • For all floor finishes: Suitable to be laid directly under all types of flooring and over existing insulated flooring.
  • Low surface finish: 22 mm floor height makes it ideal for retrofit installations and new build projects.

Pipes

-

Underfloor

PE-RT Pipe.

Guidance for specification option:

PE-RT Pipe Warmup PE-RT (Polyethylene of Raised Temperature Resistance) pipe. The pipe guarantees leak free performance with a smooth internal structure for improved flow, reduced pressure loss and deposit formation

Insulation

Manufacturer guidance

  • The Warmup Total-16 boards are made of high-density EPS with a 400 kPa compressive strength; providing extremely high resistance for short and long term loads.
  • The straight boards come with aluminium heat diffusion plates as an integral part of the board. Return boards and the multi-feed boards, which are used to transit pipes to other heating circuits from the manifold, do not have the aluminium heat diffusion plates.
  • Insulation boards have zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of less than 5.
  • Thickness: 16 mm.
  • Thermal conductivity: 0.034 W/m·K at 10°C.
  • R-Value: 0.47 m²K/W.

Accessories

Warmup Primer.

Guidance for specification option:

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.

Warmup Ultralight.

Guidance for specification option:

(Optional)

Adding Warmup Ultralight below the membrane can help improve the response time of the system, particularly when installing over screed or concrete.

Flexible tile adhesive.

Guidance for specification option:

(Optional)

Required if installing Warmup Ultralight.
