Notes

The formulae used in this sheet are based on test results of a small sample (approx 1m x 1m). The frame and mullions encroach on this area. Different width to height dimensions can change the ratio of frame and mullions to effective area quite considerably even if the total m2 is the same. This calculation is intended to give a guide on correct opening sizes. If the % cell shows up red you should increase the narrow dimension of you opening until it turns green. If this is not possible please contact Ventüer to discuss options.
