Floor
heating installed in Granab systems
Floor heating is installed in Granab systems
in increasing numbers of residential projects.
Granab systems with steel floor girders is entirely non-deformable
and not affected by temperature variations, which is a major
advantage in avoiding subsequent floor construction problems.
Installation of most available floor heating systems with
Granab Subfloor Systems 3000 and 7000 provides significant
benefits. |
 |
When
choosing waterborne floor heating, two alternative primary
systems are
installed in Granab Subfloor Systems 3000 and 7000: |
| Floor
heating in 22-mm chipboard flooring with grooves |
Grooved 22-mm chipboard flooring that is glued and
screwed in place on the Granab girders.
Floor heating plates are fitted in the grooves to distribute
the heat from the tubes to the floor. The floor heating tubes
are then pressed into the heat distribution plates.
Floor covering
15-mm parquet is laid directly on the floor heating installation,
possibly with an underlying moisture
barrier. It is important that installation instructions from
the flooring manufacturers are carefully followed. |

Floor heating
in sealed floor heating units
|
|
Heating coils are installed in the floor heating
units. The sealed unit/floor plate is fitted parallel to the
subfloor
system's girders and on the sealed unit brackets, which are
mounted between the girders (System 7000).
Standard spacing between joints, c/c 600.
Floor covering
22-mm chipboard flooring & carpet or 15-mm parquet, alternatively,
floor mortar & tiles |
 |
| Recessed
convectors |
|
 |
 |
On many residential projects,
solutions with recessed convectors are preferred; for example,
when there are glazed
floor-to-ceiling facades and downdraughts are to be avoided,
but an attractive solution is also desired without visible
radiators. In these cases, installation of a Granab subfloor
system is very beneficial in that the space between the subfloor
and finished floor can be utilised. |
