Calculate dry construction underfloor heating system

Calculate the material requirements for your dry underfloor heating system – ArdusAlu heat conducting plates, PE-RT heating pipes and dry screed panels for wooden beam ceilings and old buildings without wet screed. The dry system can be heated immediately after installation – no screed drying time of 6–8 weeks. Enter your area and immediately receive the number of panels, pipe quantity, number of heating circuits, and complete set price.

What the configurator calculates – drywall underfloor heating system

Based on your room area, the configurator determines the complete material requirements:

  • ArdusAlu heat conduction plates: Room area + 5% waste
  • PE-RT heating pipe (∅ 14–16 mm): approx. 6.7 m/m² with 15 cm laying distance
  • Dry screed panels (Rigidur / Fermacell 2E22, 22 mm): Room area + 5% waste
  • Heating circuits & manifolds: max. 80 m per circuit – for 60 m² typically 5 heating circuits
  • Edge insulation strips: Room perimeter in linear meters

Example calculation for a 60 m² timber beam ceiling: 63 m² ArdusAlu · 400 m PE-RT heating pipe (5 heating circuits) · 63 m² dry screed panels · 40 linear meters of edge insulation strips – complete set from approx. €2,100.

Häufige Fragen

How much material do I need for 60 m² of drywall system on a wooden beam ceiling?
For a 60 m² drywall system: approx. 63 m² ArdusAlu heat conducting plates, approx. 400 m PE-RT heating pipe (5 heating circuits of max. 80 m each), approx. 63 m² dry screed panels (Rigidur 22 mm), and approx. 40 linear meters of edge insulation strips – complete set from approx. €2,100. The configurator automatically calculates all quantities.
What does a complete dry screed underfloor heating system cost for 80 m²?
The drywall system complete set (ArdusAlu, heating pipe, dry screed panels, edge insulation strips) costs from approx. €35/m² – for 80 m² from approx. €2,800. The system is more expensive than wet screed solutions, but saves screed layers, heating protocols and 6–8 weeks of drying time.
Calculating a drywall system or thin-layer system for old buildings – what fits?
For wooden beamed ceilings, a dry construction system is mandatory – wet screed is structurally impossible. For concrete floors or screed in old buildings, the thin-layer system (from €25/m², 18 mm height) is more cost-effective. Deciding question: Can the subfloor support wet screed? Yes → Thin-layer. No (wooden beams, timber-frame) → Dry construction.
What installation height do I need to factor in for the drywall system?
Total structure of dry construction system: ArdusAlu heat conducting plate (13 mm) + heating pipe embedded (∅ 14 mm) + Fermacell 2E22 dry screed plate (22 mm) = approx. 35–45 mm total structure. No wet screed required. Less than the tacker system (65–100 mm), but more than the thin-layer system (18–22 mm).
Calculate dry construction underfloor heating system: How quickly is the system ready for operation?
The dry construction system can be heated immediately after installation – within 24 hours. No heating protocol is required as with cement screed (6–8 weeks drying time). This saves considerable time on the construction site and is particularly important for renovations under time pressure.
