System Description
The Warmup Tectora Joisted Batten Floor System is particularly
suitable where there is a sprung/cradled battened  oor or  oor
joists. It is used in battened installations over a concrete sub oor,
variable height  oor battens are employed to create a void of
between 50 to 100mm.
The batons can be sprung or on cradles to create an acoustic  oor.
For this installation, a di usion plate system is generally used if
standard installation types are not suitable.
For installing as a joisted system, the rigid insulation is placed
between the joists to support the di usion plates, as they span the
joists.
The Warmup Tectora Joisted Batten Floor System is suitable for
almost any  oor  nish, in particular wood or engineered wood.
Technical Information
The insulation for the Tectora Joisted Batten Floor System installed
between the joists/battens must comply with Building Regulations
in force at the time. It is supplied by Warmup.
Battens to support the insulation will be designed and installed by
the  ooring contractor and co-ordinated with the installer.
Warmup Tectora Di usion Plates are then installed between the
joists. The underside of the plate rests upon the insulation, which
in turn supports it.
This is followed by the pipework as per the approved design.
Once the system has been installed and pressure tested it should
be protected by laying the  oor covering as soon as possible.
Output from the system will be designed to meet your
requirements taking into account such criteria as  oor  nishes.

Important Information
Before commencing installation, it is important that a site inspection is performed. You will need to con rm that all
measurements and other requirements on site match your building plans.
Ensure that all sub oors are the correct depth needed to incorporate the under oor heating. Check for anything that might
interfere with pipe installation such as concrete walls where they were not expected or changes to the  oor layout.
Note: A redesign of the layout system may be required if any changes have been made.
Insulation
In accordance with Part ‘L’ of the current Building Regulations, a suitable layer of insulation material should be included
within the  oor construction. It is the responsibility of the Architect or Builder to ensure compliance. The insulation must be
installed beneath the under  oor heating system in order to ensure that any downward heat loss does not exceed 10W/m2, in
accordance with BS EN 1264.
Inspect the site for possible hazards that could damage the Warmup pipe, such as nails, staples, materials or tools. Remove any
items or potential hazards before installing pipe.
When handling the Warmup pipe it is important to protect the pipe from damage.
Uncoiling the pipe
DO NOT pull of the coil while it is sitting  at. It must be unwound from the coil, pulling from the top or the bottom of the coil.
This will require one person to hold the pipe o the ground, or the use of an uncoiling device such as the WHUF-UNWINDER.
Bending Radius of the Pipe
When laying the pipe, do not force the pipe into bends. It is easier to lay the pipe with a large radius and then gently pull the
pipe to the required bend.
The maximum bending radius is 5 times the diameter of the pipe.
Kinking
Pex- a pipe only
Excessive bending of the pipe can cause it to kink, where this occurs  ow may be obstructed or reduced. Kinked pipe must be
repaired. To repair a kink, straighten the pipe and simply heat the area with a hot air gun until the kink disappears.
NOTE: DO NOT use an open  ame to heat the pipe.
Heat around the pipe to evenly heat the surface. Ensure that you do not overheat the pipe as this will result in damage . The
maximum temperature that the PEX-a pipe can withstand is 95°C.
NOTE: Do not try to bend the pipe in the same spot.
Where the pipe is not Pex-a the circuit will need to be replaced with a new pipework.
Cutting the pipe
Use a pipe cutter designed for plastic pipe ensuring that there are no burrs on the pipe ends. It is important to achieve a clean
cut.
NOTE: If you accidentally damage a Warmup under oor heating pipe BEFORE covering it with screed or other coverings,
under the Warmup Safetynet guarantee you may return the damaged coil of pipe to Warmup, who will replace the coil FREE
OF CHARGE with pipe of the same length and type.

Important Information
Pipe Installation
Install the pipe along outside walls  rst so that the hottest (supply) water goes to the coldest areas. Pipe should not be
installed under appliances such as freezers.
If a pipe circuit is installed under  oor coverings such as carpet and tile, install pipe under the high R-value area  rst if possible,
as this area will require a higher water temperature.
Keep pipe at least 15 cm from the edges of slabs, walls or other permanent objects in order to prevent damage when this will
help to prevent damage to the pipe when these items or
ooring materials are being installed.
Plan the circuit layout ensuring that pipes can connect to manifolds without crossing each other.
Ensure that all circuits have been planned in advance to minimize areas where the pipe passes through expansion joints.
In con ned areas it may not be possible to use the designed spacing. To avoid cold spots always use tighter spacing and
more pipe rather than wider spacing and less pipe.
Pipe Bends
Protection will be required where the Warmup pipe enters the  oor. The
recommended method for protecting the pipe is the rigid PVC Bend Guide,
which holds the pipe in a 90° bend, as well as protecting the pipe from
damage.
To install PVC Bend Guides, simply insert the Warmup pipe through the
PVC Bend Guide to the appropriate length, (50-75 cm) .The PVC Bend Guide
should be positioned so that the pipe rises straight to the manifold with
approximately half the guide within the  oor.
Conduit Sleeving
Using the Warmup pipe conduit protection sleeve across all construction
joints in  oor. Locations where pipes pass through expansion joints, door
frames, walls or where the pipe could get damaged by sharp edges will require
protection.
When installing the conduit cut along the length of the conduit and clip onto
pipe.
Protecting the Warmup Pipe
Use the Warmup Pipe Bend
Support where it enters the  oor.

Warmup® Tectora Joisted Batten Floor System - Installation
Step 1
Insulation must be fitted between the joists before the Tectora System
can be fitted.
Cut the Warmup Metro Insulation to size and fit tightly between the
joists. The insulation should be supported by fixing battens between
the joists.
NOTE: Use a compressible insulation material at the end of each joist
run to  ll any air gaps in order to minimise air in ltration.
Step 2
Distribute the plates evenly across the  oor as per the installation
design. Each plate should be  tted with 6 staples. Allow 500mm for
pipe end returns and a 100mm gap between plates.
Ensure that the Warmup Diffusion plate is fully supported and remains
in contact with the final floor covering.
Step 3
The  oor joists then need to be notched or drilled in accordance with
Building Regulations.
This enables entry and exit of the pipe to and from the room. Always
allow for expansion and contraction of the pipe where it passes
through notched joists by covering the pipe in the Warmup pipe
protection conduit.
Step 4
After establishing the area to be covered by the circuit, connect to the
manifold holding the pipe at a 90° bend (see page 5)
Step 5
Run the pipework to the designed pattern by pushing the pipe into the
plates.
Locations where pipes pass through expansion joints, door frames,
walls or where the pipe could get damaged by sharp edges will require
protection. Cover the pipe with the Warmup pipe conduit protection.
Ensure that the plates remain  ush with the top of the joists.
Step 6
Fix pipe bend to the return pipe and connect to the manifold.
Step 7
Complete Steps 5-7 for each circuit.
FINAL FLOOR COVERING
Lay  nal  oor covering 90° to the plates.
Fit insulation between the joists
Distribute the plates evenly across
the  oor.
Run the pipework to the designed pattern.

Floor Coverings
Pressure Testing
A system pressure test MUST be carried out before the screed has been laid. The system should be  lled and each circuit
purged of air.
Connect the pressure tester to the drain valve and increase the pressure test to 6 bar.
Leave at 6 bar for 1 hr. If the pressure level remains stable record the results on the pressure test certi cate.
If you see that the pressure has dropped you will need to inspect the pipework for damage and  ttings for proper attachment.
Once the pressure test is complete reduce the system pressure down to 3 bar during screeding to protect the pipework.
When installing an under oor heating system the thermal conductivity of the  nal  oor covering must be considered at the
design stage.
Ensure that the  oor covering is suitable for use with under oor heating. It is also important to check that any adhesives used
with the  oor covering are suitable and can tolerate the  oor surface temperatures.
Timber  oors
The important factor is the  oor moisture content.
Timber  oors can be laid directly over the screed if they have a moisture content of 10-11% which when heated will reduce to
8-9% and may cause a small amount shrinkage.
The  oor will re-absorb some moisture when the heating is not operating and the moisture content will increase to 12-13%.
The timber  oor  nish should not exceed 18mm in thickness. Timber  ooring carries a 27°C surface temperature limit.
Carpet
The thermal resistance of carpets and underlay is fundamental in attaining good heat transfer.
The most popular underlay type is sponge with a waffl e pattern molded into the underside.
These allow good heat transfer. Felt and rubber crumb underlay should be avoided. These products can seriously reduce the
e ectiveness of an under  oor heating system, as they insulate the  oor surface and prevent heat transfer. For optimal system
performance choose an underlay with a maximum TOG value of approximately 0.5. The maximum combined TOG value of
carpet should not exceed 2.5 TOG.
Tiles
These  oor coverings work well with under  oor heating. The Tiles should be laid on a full bed with no air gaps. It is important
that the design of the supporting  oor structure is stable and rigid to prevent cracking. It is recommended that  exible
adhesives and grout be used.
Vinyl
Check the  oor surface temperature indicated by your vinyl supplier for compatibility with under  oor heating.
Vinyl  ooring carries a 27°C surface temperature limit.
