Underfloor Heating

Underfloor heating with Granab

Underfloor heating is installed in Granab systems in an increasing number of residential projects.
Granab systems with steel floor girders are entirely non-deformable and not affected by temperature variations, which is a major advantage in avoiding subsequent floor construction problems.

Most available floor heating systems can be installed in combination with Granab Subfloor Systems 3000N and 7000N, which provide significant benefits.

When choosing waterborne underfloor heating, two alternative primary systems are installed in Granab Subfloor Systems 3000N and 7000N:

 

Grooved chipboard above Granab girders

Underfloor heating pipes fitted in 22mm chipboard flooring with grooves that is glued and screwed in place on the Granab girders.

 

Sealed floor heating units between Granab girders

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).

 

Recessed convectors

On many residential projects, solutions with recessed convectors are preferred: for example, when there are glazed floor-to-ceiling facades and downdraughts need to be avoided, but an attractive solution without visible radiators is also desired. In these cases, installing a Granab subfloor system is highly beneficial in that the space between the subfloor and finished floor can be utilised.
