About U-Solve

U-Solve is a custom software application to determine the 'Whole-Window' U-Value and SHGC Value of an aluminium window or door. It is based on the extrusion systems available from Wispeco (Pty) Ltd in Southern Africa.

U-Solve does NOT approximate the U-Values and SHGC Values. It calculates the actual values from detailed software simulations using the 'Therm' and 'Window' software available from the Lawrence Berkley Laboratories in the United States. U-Solve is the ONLY program currently available in Southern Africa that performs these detailed calculations.

U-Solve is written for the MS-Windows platform, since this is the most widely used operating system in Southern Africa. It is possible to run U-Solve on an Apple Mac computer using the "Wine" application available on the Apple iStore.

U-Solve incorporates the SANS204 calculations that need to be performed for every new building being erected in South Africa. U-Solve is endorsed by SAFIERA and the calculations have been verified against 'hot-box' testing by AAAMSA and SAFIERA.
