Multi Layer Alu PERT Tubing AluLaser Plus for Radiant Heating

Energy savings
Room temperatures can be reduced by as much as 5°F (2.8 C) without sacrificing comfort. For a typical home this means you can save up to 30% on heating. When doors are closed, up to 50% of the heat will be recovered instantly. Half of the total heat is provided by radiation, which travels at the speed of light.


Cost savings
Roth systems are easy to design, and can be installed quickly. Your certified Roth system installer has ready access to world-class technical support, heating system design data and engineering.


Quiet operation, health and safety issues
Water is far denser than air so it carries much more heat. Additionally, the water runs slowly through noise-absorbing plastic tubing. Small residential circulators are so quiet they can't even be heard in the utility room. Radiant heating minimizes air movement, which reduces drafts in the home. As a result, dust, germs, viruses and mold aren't spread around the home. Allergy sufferers can breathe a sigh of relief.


Decorating freedom
The entire system is hidden, and there are no obstructions to interfere with the use of the room. There will be consistent heating throughout the entire house without any design restrictions.


Comfortable basements
What was once a damp, often chilly room can quickly be turned into a comfortable prime living area. Warm floors keep rooms dry and basement floors are now as comfortable as the floors on any other level.


Warm floors never stay wet
Water on the bathroom floor? No problem. Snow and ice in the garage? Don't worry. Roth radiant heating ensures that, if wet, your floors - and shoes, towels and clothes - will dry faster, and stay dry longer; which helps to eliminate mold, mildew and pesky, unwanted odors.


Hydronic Radiant Heating Systems: Heat that's alway's "in the zone".

Comfort control
Roth systems are designed to ensure easy control of heating in each room or zone. Thermostats for each separate heating zone give you effortless touch control to accommodate warmer bathrooms or cooler bedrooms for example. Direct sunlight, a burning fireplace, a large number of active guests many such factors can disrupt the heat distribution of a traditional system, resulting in both higher costs and temperature-related inconveniences. Roth puts an end to these and other problems with a system that provides the ultimate in control, efficiency and savings. Nothing compares to a Roth Hydronic Radiant Heating System.


Superior PEX Tubing
Roth manufactures the highest quality PEX tubing, made of crosslinked polyethylene, to guarantee unparalleled long-term performance. Two major components of the Roth hydronic radiant heating system are the proven PEX distribution tubing, and superior one-piece supply and return manifolds. Both help ensure economical, trouble-free installation of a system that will provide you with peak efficiency, ultimate comfort and long-term service.


Professional support from planning through design and installation
Roth will provide you with assistance, including heat-loss calculations, for your ultra comfort zone hydronic radiant heating system. Using leading-edge software programs, Roth's design and technical support team will guide you through every aspect of the project. Roth-trained installers will receive ongoing support throughout the installation, including easy-to-follow installation manuals.


The Roth PAP is a composite tubing consisting of an inner layer of extruded PE tubing, an inner adhesive layer, a center layer of ultrasonically welded aluminum tubing, an outer adhesive layer, and finally an outer layer of extruded PE tubing. As a result of the co-extrusion process, the composite tubing provides the following advantages:

  • An impervious oxygen barrier
  • Shape retainment after bending
  • Reduced expansion and contraction compared to PEX only tubing
  • Improved burst resistance
  • High resistance to corrosion and to scaling from minerals dissolved in the system water


Material Standard: Manufactured in accordance with ASTM F1282 and tested for compliance by NSF to both US and Canadian standards and marked as cNSFus-rfh.

Minimum Bending Radius: No less than 5 times the tubing outside diameter.

Nominal Inside Diameter: Nominal inside diameter in accordance to ASTM F1282.
