Understanding The Visual Quality Of Glass

Are you looking to replace outdated windows and upgrade them for maximum durability? If yes, then your new windows need to have glass with high visual quality. When you are planning to install windows and insulated glazed units, you should expect a certain level of quality. The glass used for sealed window units is similar to glasses used for single glasses, meaning they have the same level of visual quality.

Go through this blogpost to know how you can professionally assess the quality of your double glazed window units and improve overall aesthetics of your valuable property.

When to inspect your sealed units?

You should inspect your sealed units at a reasonably practical time after the installation. Ensure you check for glass units and windows before plastering or working around the new windows.

How to professionally inspect new window units ?

The following inspection process will help you check your glass units for noticeable damage.

• Check the glass units during the daytime to use natural light but avoid carrying out the inspection when the glass unit is directly facing the sun and has no visible moisture on the surface

• Stand inside the room at a distance less than two meters from the window and look through the window, not at the window

• If the window is laminated, toughened or has other coated glasses, stand not less than three meters away from the glass

• Inspect the glass at a 90-degree angle
• Remove a 50mm band resound the glass edge

What you should expect to see

Your flat transparent glass, including coated, laminated or toughened glass, is in good condition if the flowing flaws are absent.

• Blisters or bubbles
• Minute particles
• Fine scratches not above 25mm long

Sealed glass units with visible defects such as fingerprints, smears or dirt inside or on the glass cavity require a re-do, especially is if the defect is visually disturbing.

What to do when a glass has impaired visual quality

If you notice flaws in the new glass units, ensure you contact your glaziers to carry out a visual inspection and commercial window repair. Your glaziers will get a factory remake of the unit for replacement if necessary.

Natural vision and special glasses

Different glass types have unique characteristics that make them different from other glass. These characteristics include:

• Toughened glass

This glass usually has visual distortions which sealed units accentuate. This visual distortion is natural, not a blemish.

• Laminated glass

Laminated glass may have some imperfections from the manufacturing process because it is manufactured from several glass layers with clear plastic.

• Coated glass

This glass with materials that have low emissivity may show transient visual effects. Some lighting may make the glass have a transparent film.

• Insulated glass

Insulated glass units reduce condensation, but condensation can still occur in some conditions.

In some cases, glass units create Brewster’s Fringes when they refract light. Brewster’s Fringes are small transitory rainbow effects when high-quality glass sheets are parallel.

Under some light conditions, multiple reflections can occur in glass units. The reflections are due to several surfaces in the triple or double glazing windows. This reflection is natural and not a flaw.

The visual imperfections do not apply to patterned glass because the manufacturing process is different. This makes bubbles and seeds acceptable.
