Maintenance of glazed units

Insulating glass units require periodic cleaning and inspection to maintain their appearance and performance.

Cleaning

• Clean the glass regularly with clean water and a non-abrasive cloth or squeegee.
• Mild detergents may be used; avoid alkaline cleaners, abrasive products and metal scrapers.
• Avoid cleaning the glass in direct sunlight or when it is hot.
• Rinse thoroughly and dry to avoid streaking.
• Take care not to damage the perimeter seal of the unit.

Avoiding damage

• Do not allow alkaline materials (cement, plaster, mortar) to come into contact with the glass.
• Remove stickers and labels with care to avoid scratching the glass.
• Do not stick adhesive tape, paint or stickers directly to the glass.
• Do not allow welding sparks or hot metal fragments to come into contact with the glass.

Inspection

Periodic inspection of the glazing should include:

• checking the glazing gaskets or sealants for signs of deterioration
• checking the drainage and ventilation slots for blockages
• checking for any signs of seal failure (misting or condensation within the cavity)
• checking the frame for signs of movement or distortion.
