Calculadora de Membrana para Techo Plano — m a rollos, adhesivo, costo
Cómo usar esta calculadora
Enter flat roof dimensions en metros y centimeters — length × width or direct area. Choose membrane type (EPDM, TPO, PVC o bitumen modificado), roll width (1.5 m or 3 m), y seam overlap. Results include rolls, adhesive, edge trim, y optional insulation boards with cost estimate.
Tipos de membrana — EPDM (rubber), TPO (heat-welded), PVC (chemical resistant), Modified bitumen (torch/cold-applied).
Traslape — 75–150 mm depending on membrane type. Select your currency for cost estimates.

Cómo Calcular Membrana para Techo Plano (Metric)
This calculator estimates membrane rolls, adhesive, edge trim, fasteners, y optional insulation boards para techos planos o de baja pendiente. Supports EPDM, TPO, PVC, y modified bitumen membranes with metric dimensions. Roll widths of 1.5 m y 3.0 m with lengths of 15–25 m are available.
Fórmulas
Effective cobertura = (ancho del rollo − traslape) × longitud del rollo. Rolls = ceil(area × (1 + waste%) / effective cobertura). Adhesivo = area / 10 m² per litre for fully adhered, in 20 L pails. Fijaciones ≈ 10 per m² for mechanically attached systems.
Preguntas Frecuentes
What overlap for TPO/PVC? Heat-welded seams typically require 75–100 mm overlap. Modified bitumen uses 100–150 mm. Always follow manufacturer specifications per EN 13956.
Do I need insulation? EN standards require thermal insulation below the membrane. Typical boards are 1.2 × 2.4 m polyiso or EPS.
