Storage of insulating glass

Insulating glass must not be set down on a corner or edge. Likewise, the windows must never be placed on hard surfaces such as concrete or stone floors. Even minor damage to the glass edges can later be the cause of glass cracks. For this reason, insulating glass should always be placed on wood or a firm plastic base, whereby area separation (at least 3 mm) and low inclination (about 6 degrees) should be ensured. All units are to be supported.

Protect against moisture

In the case of glass panels lying on each other, moisture leads to surface chemical reactions such as leaching. As a result, visible damage to the glass surfaces can occur within a short time. The glass must therefore be stored and transported according to the moisture present.

Protection against heat radiation

Glass packages stored outside absorb the rays of the sun much more than single panes. Strong, uneven heating occurs in the glass stack. As a result, glass breakage due to thermal overload and damage to the edge seal are possible. Especially endangered in the stack are coloured and coated glasses, ornamental and wire glasses. Such glass packages must therefore be protected from direct sun irradiation and, if necessary, stored in dry, well ventilated rooms. It is also recommended to loosen and remove any packing clamps after settling down in the storage location.

Protect from UV radiation

Insulating glass stored outdoors must not be exposed to sun irradiation because the “normal” edge seal is not UV-resistant and the surface of the edge seal can be damaged by UV radiation. If, however, panes have to be stored outdoors, they must be protected against UV radiation by covering with non-transparent foils or the like. Insulating glass, whose edge seal should be permanently exposed to direct sun irradiation, are to be designed with a UV-resistant edge seal.
