1 Cálculo del coeficiente de transmisión térmica (Uf) Ventana de Rebatir de 2 hojas M-Tres (Encuentro central), con Poliamida de 25 Cliente: Alcemar Cálculos realizados por Technoform BAUTEC Ibérica, s.l. Laia Cardona Tel: / Fax: tb-es@technoform.es Fecha: Resultados Puerta de rebatir RPT M-3\25 mediante BISCO según norma EN ISO :2003 Uf = 3,31 W/m 2 K Puerta de rebatir RPT M-3\25 mediante RADCON con Know-How TECHNOFORM Uf = 3,04 W/m2K En este informe se detemina el coeficiente de transmisión térmica (Uf) mediante dos métodos de cálculo diferentes: A) Aplicando la norma EN ISO :2003, y usando el software BISCO de la empresa Physibel. B) Aplicando un método própio, know-how de Technoform, dónde se usa el software RADCON - también propiedad de Physibel - y el valor final equivale aproximadamente al resultado en el test de cálculo de nuestra HOT-BOX (La diferencia es de un 5%) según norma ISO/FDIS 12567:
