Floor Construction Methods

Underfloor
Heating - Floor Finishes
|
|
|
|
Underfloor
heating can work successfully with all floor
coverings, however some are better at transferring
heat than others. The best floor coverings
for use with underfloor heating are hard surfaces
such as stone and ceramic tile as they have
the least resistance and transfer heat effectively.
Most floor finishes are able to cope with an
underfloor heating system dependant upon whether
the underside of the floor is well insulated.
Some floor covering manufacturers stipulate a
maximum floor temperature for their product.
BS1264 states that underfloor heating systems
should not operate at higher than 29°C.
Care is required to check the floor finish manufacturer’s maximum temperature
limits against the maximum design floor surface temperatures for a given room
or space.
Wood, vinyl tiles and plastic floor covering fall into this category whereby
the finishes are considered to be hard wearing but in fact are temperature sensitive
and consequently considered to have low surface temperature limits.
Most fitted carpets can be actually good transmitters of heat, however it is
imperative that the underlay is of a waffle type and suitable for Underfloor
Heating (UFH) whilst being of a low Tog value.
In refurbishment projects, such as barn conversion which require high heating
outputs, greater care is required and hard surfaces such as tiles or stone may
be the better chosen options.

| Carpet |
|
Most types
of carpet can be used with Underfloor
heating, although care needs to be taken
with regard to the underlay, thermal
underlays are not suitable as they do
not allow the heat to pass through to
heat the room. Carpets and underlays
are measured in Tog values (in the same
way as a duvet) the lower the tog value
the easier the heat will pass through,
combined Tog values for the underlay
and carpet should not exceed 2.5 for
your underfloor heating system to work
effectively. |
| Stone & Ceramic
Tiles |
|
|
Most
stone tiles, slate and marble, are really
good thermal conductors making them a
great option for a floor covering over
underfloor heating. Ceramic tiles also
work well and allow the heat to pass
efficiently through the tile.
|
| Timber
flooring |
|
|
Timber
flooring is suitable for use with underfloor
heating, indeed the underfloor heating
can actually be beneficial to the flooring,
without the hot spots from radiators.
Care must be taken to ensure that the
timber moisture content does not exceed
10% when the floor is laid to prevent
movement in the floor as the timber dries
out.
|
| Laminate
flooring |
|
|
A
popular choice as the system is easy
to lay and allows a good heat output
from the floor, engineered timber options
are now available to have a real wood
finish but without the cost.
