WinUw is a program for calculating the heat transition coefficient of windows according to EN ISO 10077-1

Features:

• Calculation of Uw-value of windows according to EN ISO 10077 taking account to window size, Uf, Ug, Psi and frame width.
• Cross section of the frame including glass and glass edge region will be presented in detail
• Diagram showing Isotherms, heat flows and surface temperatures.
• Calculating two dimensional thermal conductance
• Calculating the heath transfer coefficient with respect to it´s length
• Determination of increased heath flow caused by interactions of frame profile and edge of insulation glass, plus the effect of spacers.
• Material of the frame definable
• Spacer can be selected out of database or entered manually
• Glass, double, triple or manual data entry
• Calculation of mean U-value for the whole facade
