Frequently Asked Questions

What are the floor panels made from?

100% recycled rubber. For a better planet.

What finished flooring(s) can be used on top of the product?

Most typical floor materials are suitable, however, please contact us to discuss how to get the best results.

How thick can the finish flooring be on top?

18mm is the maximum thickness that should be used. Typically wood laminate is about 12mm thick. Porcelain Tiles should be atleast 8mm thick. Ceramic Tiles should be atleast 10mm thick. All tiles should have atleast 200mm edge distance.

How thick are the rubber panels?

Approximately 19mm. This ensures the panels can be used to retrofit under floor heating with minimal impact on ceiling height. 

Do I need to put insulation underneath?

No. The rubber panels are a good insulator (Approximate R Value of 1.65).  Any additional insulation would improve the efficiency of the system but they are not essential.  The system is unique as it also provides excellent structure and airborne noise insulation.

what are the benefits when compared with screed systems?

For retrofit systems it is not necessary to dig down which is both expensive and dirty. To understand further the problems with screed systems please visit: https://www.pbctoday.co.uk/news/building-control-news/ufh-systems/51320/

Does your firm do the installation or are there subcontractors?

We are the manufacturer of the modular radiant panels, and we can assist with proper design and installation, but we would recommend other mechanical contractors do the actual installation.  The panel installation is also a good DIY project as long as you have a professional mechanical contractor come in to install the boilers and hook up the pex tubing. In other words, you have options. 

Do we need to be concerned about the system leaking?

There are no joints or connections in the tubing carrying the heated water under your floor.  There is one continuous closed loop of tubing, one end leaves the manifold, and the other end connects back to the manifold.  So there is no need to worry about joints or connections resulting in leaks under your floor.  Your risk of water leaks is probably higher with the plumbing system running through your house than it is with a properly installed radiant heat system. 

Can wood flooring be screwed, glued or floated over SRT’s panels?

All of the above.  If you wish to nail the floor, we recommend using a 1 1/4″ wood nailer strip between every other panel.  Floating floors are faster and well suited to engineered hardwoods.  We have had wonderful results gluing down wood floors of various thickness. 

What size are the SRT panels?

The panels are 6” (150mm) x 24” (600mm)  x 0.75” (19mm) thick. 

ARE the panels flame retardant?

Yes, the material resists combustion and surpasses CAL 01350 emissions testing. Other panel systems are made from polystyrene which is highly flammable.

How much do the panels weigh?

Each panel is about 1.5kg.  In almost all cases, standard structures will support the weight of a floor utilising our panels with no modification.

how do you affix the panels to the sub-floor?

This is not necessary! The panels are designed to be fitted as quickly as possible. They are shaped to fit together like a jigsaw, avoiding the time, cost and inconvenience of this additional work.

Any advice for fitting under carpets?

Combined underlay and carpet should be 2.5 Tog or less. Fit 3mm HDF above the panels and below the underlay. Screw the permimeter of the HDF to the panels before affixing the carpet grippers (ensuring the tubing is avoided!).

any advice for fitting under Ceramic/porcelain tiles?

Fit Fermacell 2E22 or similar product above the panels before affixing the tiles.

Can seneca radiant HELP plan the layout?

Yes, please send a sketched design showing the room(s) dimensions, positions of doors and windows and manifold position to info@senecaradiantuk.com.

any advice for laying the pipe?

  • The tubing is very strong and therefore very stiff. It will require some manipulation to straighten the tubing and/or fit it to the curves.
  • It may be necessary to use dead weights to hold the tubing in place during installation. 
  • Fit the manifold to the wall and attach the flow end before laying the tubing.
  • If the tubing is passing through a wall, cover the end of the tubing with tape prior to passing it through the wall to avoid debris entering the tube.
  • Ensure the correct manifold adaptors are used (also supplied by Seneca Radiant UK).
  • Test the UFH system prior to fitting the finished flooring to ensure there are no leaks etc.

ANYthing else?

  • As the system does not use any wet products (eg screed) the system can be used immediately. If you are affixing tiles, ensure the adhesive has dried (according to the manufacturer's guide lines) prior to using the UFH system in earnest.
  • We recommend that the connection of the manifold to the central heating system is carried out by a competent plumber.
