Velcro System Costs 2026: Material Prices, m² Calculation & Comparison

Material cost accounting: How to calculate correctly: The material costs for a hook and loop system consist of three items: (1) hook and loop fleece (Slim or Silent), (2) PE-RT heating pipe, and (3) edge insulation strips. For a 10 cm pipe spacing, you will need 10 m of pipe per m² of heated area. The edge insulation strip corresponds to the room's perimeter. For calculation: Area (m²) × pipe meters + edge insulation strips according to perimeter. Use the complete set (€12.09/m²) for the simplest ordering.

Why Slim is cheaper than Silent: The Slim hook and loop system costs €6.00/m² (fleece), Silent €9.99/m². The additional charge of €3.99/m² for Silent is due to the thicker fleece structure (5 mm instead of 2 mm) with an integrated sound insulation layer. For 50 m², this results in an additional cost of approx. €200 — a worthwhile investment in multi-family homes, where Silent meets DIN 4109 requirements and avoids expensive retrospective sound insulation measures.

Hidden Cost Factors: In addition to fleece, pipes, and edge insulation strips, further costs arise: EPS thermal insulation boards (€5–€15/m² depending on thickness), leveling compound/screed (€15–€35/m² material costs + installation by a specialized company: €20–€40/m²), manifold system (€150–€400 depending on the number of heating circuits), and control technology (€100–€300). The pure material costs for fleece, pipes, and edges typically only account for 25–35% of the total cost of underfloor heating.

Economies of scale: More space = cheaper per m²: The table shows: For 20 m², Slim costs €14.80/m²; for 100 m², it's only €13.51/m². The price difference mainly arises from the perimeter insulation strip: for small areas, the perimeter is larger relative to the area. When purchasing in larger units (e.g., 200-meter pipe rolls), pipe unit costs also decrease. Recommendation: Always buy complete rolls — leftover material can be used for other rooms.

Operating costs: Velcro system saves long-term: Underfloor heating systems with low-temperature systems, such as the Klett system, reduce heating costs by 10-15% compared to radiators due to more even heat distribution and lower system temperatures. In combination with a heat pump (flow temperature 30-45 °C), the COP increases by 0.5-1.0 units compared to higher flow temperatures. For annual heating costs of €1,000, this translates to savings of €50-100 per year.
