Calculadora de Aislamiento de Techo y Atico — m, R-value, cost
Como usar esta calculadora
Ingrese el area del piso del atico (largo x ancho o area personalizada en m2), seleccione el tipo de aislamiento y el Valor R objetivo. Si tiene aislamiento existente, ingrese su profundidad y tipo. Los resultados se actualizan al instante con bolsas/rollos, profundidad a agregar, barrera de vapor y deflectores de ventilacion.
Tipos de aislamiento — blown fiberglass (R-0.044 W/mK), blown cellulose (R-0.038 W/mK), batt fiberglass (R-0.040 W/mK), batt mineral wool (R-0.037 W/mK).
Valor R — resistencia termica in m²·K/W. Higher is better.

How to Calculate Attic Insulation (Metric)
Esta calculadora estima insulation depth in centimeters, number of bags or rolls, and cost to reach your target thermal resistance (R-value in m²·K/W). Enter attic dimensiones en metros or centimeters, select insulation type by thermal conductivity (λ), and set your target R-value.
Formulas
R = thickness (m) / λ (W/mK). Depth needed = (Target R − Existing R) × λ. Bags = Area / Coverage per bag at target depth. Coverage decreases with depth for blown products. Batt rolls are area / roll coverage.
Thermal Conductivity (λ) Values
Blown fiberglass: λ=0.044 W/mK. Blown cellulose: λ=0.038 W/mK. Batt fiberglass: λ=0.040 W/mK. Batt mineral wool: λ=0.037 W/mK. Lower λ = better insulator = less depth required.
Preguntas frecuentes
Puedo combinar tipos de aislamiento? Yes, R-values are additive. Blown insulation works well over existing batts. Vapor barrier? En climas frios, install on the warm side of the insulation per EN 13788. In mild climates, consult local building codes.
