Care and maintenance of your double glazing.
Congratulations on your new high-performance double glazing from ComfortGlaze, a member of theWindow and Glass Association of New Zealand (WGANZ).
Carefully read this guide before cleaning & maintaining your glazing.
Following the instructions in this guide is required in order to comply with warranty requirements and will aid in retaining the appeal of
your glass for many years to come.
Regularly clean your glazing as per the regular cleaning process below.
FOR HARD TO REMOVE MARKS
Remove oily spots and other organic pollution with isopropyl alcohol or acetone applied with a soft, clean cloth.
Ensure these products do not enter the Glazing Pocket (Figure 2).
Rinse glass with clean water then follow the regular cleaning process.
FOR REFLECTIVE OR COATED GLASS
Coated glass has a thin metal oxide coating that is applied to the glass. These coatings are very resistant and durable. No precautions
need to be taken when the coating is positioned on the inside of the insulating glass unit (Figure 2: Surface 2 or 3).
For single glazing or when the coating is located on the outside of the insulating glass unit (Figure 2: Surface 1 or 4), the regular
cleaning process described prior is suitable.
However, bear in mind that a transparent and very thin metal surface is being washed.
Test your method on an inconspicuous spot first.
DO NOT scratch the surface, this will penetrate the coating and it cannot be repaired
DO NOT use a mechanical treatment, this may remove the coating in localised areas
DO NOT let metal objects come into contact with the glass
DO NOT use products containing hydrofluoric acid, fluorine derivatives, any abrasive elements, or high acidic or alkaline content.
These will attack the coating and damage it irreparably.
CLEANING YOUR GLAZING
Regular cleaning of your glazing is recommended every three months.
Commence cleaning by soaking the glass surfaces with clean water to loosen dirt and debris.
Then wash the glass using clean water, glass cleaning squeegee or clean cloth, and one of the recommended cleaning products listed on reverse page.
Rinse with clean water and wipe dry with a clean squeegee ensuring the glass is dry and water droplets are removed to avoid permanently marking the surfaces.
Use this cleaning time to check drainage holes are clear, glazing gasket and flashings are intact.
DO NOT wash your windows in direct sunlight
DO NOT let metal objects come into contact with the glass
DO NOT use products containing hydrofluoric acid, fluorine derivatives, any abrasive elements, or products with high acidic or alkaline content.
Due to the process of toughening glass, it is possible that very fine glass particles may fuse onto the glass surface.
Care must be taken not to dislodge and drag this over the surface as it will cause scratching.
Toughened glass can be identified by its safety stamp (Figure 1).
