Maintenance and cleaning of glass packs

Maintenance

Construction materials, such as window frames, paint, sealant connectors or bands, are the objects of natural ageing process.

In order to maintain the term of guarantee in effect and extend the term of operation of glass packs, it is necessary to carry out regular tests of functioning. All maintenance works, such as window frames, leakage test for seal between the glass and window frame, inspection of ventilation and steam pressure equalisation holes have to be carried out regularly and at appropriate intervals

Glass cleaning

The construction contractor is responsible for cleaning of glass units in mounted windows as well as removal of remainders of labels and seals using mild cleaners.

Grease which cannot be removed from a glass using ordinary cleaning with water or spray-cleaners available for purchase can be removed using a sponge or household cleaners.

Tolls which can leave scratches as well as razors and scrapers should be avoided as they can leave scratches on the glass surface.
It is especially important that mortar and alkaline substances of construction materials were removed immediately; otherwise the glass surface can be damaged and look like frosted.
If sealing materials fall on the glass, they should be cleaned immediately.

Special cleaning instructions are given for glass coated with metal-oxides:
  • ordinary grease can be removed as described above without using abrasive cleaners;
  • resistant grease, i. e. spots of paint or pitch, sticky scrap should be dissolved in certain solvents, i. e. methanol, acetone or cleaning liquid, and them washed. When solvents are used for cleaning, they should be used with care, avoiding damage of the sealed edge, sealer or other organic parts of the glass pack.

Unsuitable cleaners

Glass must never be cleaned with strong alkaline solutions or acids, especially hydrofluoric acid or other cleaners containing fluoride.
Such solutions can damage the glass and its coating, thus causing irreparable damage.
