Technical data Wall heating in drywall construction with counter battens Wall heating with heating plaster
Heating circuit length ø 80 m (~ 12 m²)
Weight 5 kg / m² (without drywall panel / heating plaster)

 

Important Information Wall heating in drywall construction with counter battens Wall heating with heating plaster
Adhere system panels Adhere system panels to the raw wall using tile adhesive, dispersion adhesive such as MAPEI ultra bond EcoFix or non-floating PU adhesive
Waterproofing If the wall heating is installed on an outside wall, check the dew point and add a vapor barrier if necessary.
Installation Screw Fermacell drywall panel every 25 cm with Fermacell screws 30 x 3,9 mm to the counter batten; Install and adhere panels butt-jointed

Screw Rigips drywall panel (RB/RBI) every 25 cm with Rigips screws TN 30 x 3,8 mm, Climafit with Climafit screws TBGOLD 9,5 23 mm to the counter batten; Install panels with joint width of 5 - 7 mm and fill with Rigips Vario filler
Use reinfocement grind with 1,05 mm thickness and mesh of 19 x 19 mm; Install in rows with 10 cm overlapping and mount with 3-part wall heating dowels 75 mm (min. 8 pcs/m² and 3 per overlapping area)

When using gypsum-lime plaster or clay plaster, heating can be started immediately according to heat-up protocol; When using lime-cement plaster, heating can be started after 2 weeks according to heat-up protocol.

If the surface is only painted, an additional fabric reinforcement in the lime-cement plaster is necessary.
Note detailed information in the guidelines of the manufacturer
Important information Max. flow temperature with drywall panels: 50°C

Wall - and ceiling connections need to be elastic run to absorb the thermal expansion (e.g. with edge insulation strips)
Light plaster and thermal insulation plaster are not suitable

Max. flow temperature with gypsum-lime plaster: 60°C, with clay plaster: 50°C, with lime-cement plaster: 65 – 70°C

Wall - and ceiling connections need to be elastic run to absorb the thermal expansion (e.g. with edge insulation strips)
