Vertical Gas Filling
Vertical gas filling is a means of filling an insulated glass sealed unit with gas when the unit is placed in the vertical position.
Gas corner keys with holes in can be purchased. Alternatively, two 5mm holes are drilled as close to each end a spacer bar that has not been filled with desiccant. The sealed unit is then constructed with primary seal and positioned vertically. The holes are positioned either as below or on its side with one hole.

The sealed unit is then constructed with primary seal and positioned vertically. The holes are positioned either as below or on its side with one hole.
Once the unit has been filled with the selected gas, the holes are plugged and a secondary sealant is then applied to minimise gas loss.
Horizontal gas filling is generally the method of filling insulated glass sealed units through one hole either through a specialist gas corner key which is supplied with a hole already in, or through a hole drilled in the perimeter or the spacer framework.
