Fundamental Causes and Signs of Double Glazing Failure

Double glazing protects the home's efficiency and comfort from the outside world. But like any other protection, it could exhibit corrosion over time. Early detection of double glazing breakdown is an option for prompt maintenance rather than a reason to fear.

Let's review the top five signs of double-glazing failure.

What is Double glazing?

A double-glazed window has two glass panes. The primary part of the window is the double-glazed sealed unit, sometimes called an Insulated Glass Unit (IGU).

A spacer bar creates the insulating gas-filled air gap between the two glass sheets that make up the IGU. The primary benefit of double glazing is thermal insulation. It increases a room's energy efficiency by controlling chilly air from entering and keeping heat in.

Symptoms of Failed Double Glazing

As the double-glazing feature stops working, you will begin to notice breezes coming through your windows. In an ideal double-glazing window, air should never enter through the windows. Have you recently found it difficult to maintain the inside temperature of your home, even after closing all the doors and windows?

If you see air coming through your double-glazed windows, contact a professional double-glazing repair specialist immediately for additional assistance. Air in a double-glazed window indicates a possible problem with the weather seal. If is is damaged, it may cause the window to fail.

Water Leakage through the Window

Experts design the windows to shield your house's interior temperature and condition from the effects of outside factors like heat or rain. Double-glazing windows are meant to control weather conditions. When they don't, it is a sign that something is wrong with the double-glazed feature.

You must take serious action if you discover water leakage through a double-glazed window during a downpour. This is a sign that the double glazing is about to break. A weather seal inside or around the window is losing function.

Fissures or Breaks in the Glass

Your window's original panes showing signs of chipping or cracking. These indicate that the double-glazing mechanism isn't functioning. Broken window panes can occur due to various causes, including bad weather. Extended fissures in window glass may allow harsh outside elements to enter your house.

Small chips, cracks, or holes in window panes sometimes go unnoticed. However, they can worsen with time and cause difficulties like water leaks and other associated concerns. Therefore, you can find and repair any apparent chips or breaks in the window pane. Take the advice of a double-glazing repair expert. They can evaluate the damage and offer guidance on whether the window unit has to be replaced or if the cracks can be repaired. Their knowledge will assist you in making an educated choice about the required replacements or repairs.

Condensation Turns into a Problem

Condensation is normal inside and outside of double-glazing windows during the colder months. Condensation on the window's exterior indicates that the window is operating. Nevertheless, condensation forming between the two panes of your double-glazing window can be a significant problem since it might cause the window to break.

Usually, a broken or misaligned weather seal lets moisture into the gap between the panes, resulting in condensation. You can resolve this problem quickly to restore the double-glazing window.

Having Trouble Opening and Closing the Window

A double-glazing window that opens and closes ensures it's in good working order. A double-glazed window that requires more physical effort is a sure sign of hidden issues with the window. A double-glazed window that gets jammed is often the result of excessive moisture forming between the two panes. At that point, it becomes difficult to open or close as smoothly as it once did.

Primary Reasons for Double Glazing Failure

Window size

Windows' chances of breaking depend on their size and form. Small or even round windows have little chance of breaking when considering the aspect ratio. This is because glass panes are shorter than larger ones and have less space to turn. Thus, there's a higher chance that a tall, thin glass would break or develop pressure fractures in these situations.

Issues with the Actual Window Unit

Human error is unavoidable, even with the most significant technology available. Experts must manufacture double glazing with extreme accuracy to be flawless every time. Unfortunately, mistakes might happen throughout the production process. The production of double-glazed window units involves on several factors. These are the procedures, equipment, labour expertise, and environmental conditions.

Mark on the outside

Because window design makes glass cutting more complex, there is a higher chance of scratches. Even a tiny scratch at the centre of the glass pane can create a weak point. This is more risky when the expert cuts more complex glass, such as bevelled glass.

Temperature and Humidity

We also need to consider the temperature of the glass. For instance, low atmospheric pressure during the summer increases the danger of glass breakage in the winter. In this regard, learn that winter is the most popular season for window repairs due to variations in indoor and outdoor temperatures.

Moisture inside the unit also causes the same issues. Desiccant materials are frequently used in the production process to absorb moisture, which helps to keep condensation droplets from forming inside the window. However, this procedure also alters the window's pressure. Therefore, windows made during hot, humid days are more likely to crack as the temperature lowers.

Glass Hardness

If the glass used is strong enough, window glass cracking can be minimised. Pressure cracks are less likely to occur in larger glass panes than in smaller ones. At Surrey Glaziers, we always advise choosing a 6mm pane rather than the more typical 4mm pane.

Other considerations are also important, such as the location of the pressure, the size of the unit needed, and the layout of your home. Manufacturers have recently implemented environmental controls to lessen the effects of these environmental elements. Nowadays, most manufacturers can provide glass replacement services. They also offer a warranty against these unplanned breaks.

An Outdoor Temperature Rise

Ensuring heat distribution over the glass prevents window cracks during the humid summer months. It also assists in lessening the potential damage that a direct solar beam in one area may cause the glass. Windows that receive direct sunlight in the summer are more likely to crack in the winter.

This is because a beam of the sun suddenly reappears during the day when the glass cools over the night. However, this only heats the area it strikes. Therefore, it's likely that the corners of the windows remain uninsulated from the outside air and will take longer for the temperature to rise. The temperature differential causes the double glazing failure.

In the winter, you can drape pale-coloured curtains inside the glass to distribute the heat more evenly. This helps distribute the heat uniformly and reflects it onto the glass.

The Internal Temperature of the House

Because we turn on and off our central heating systems during the day, the temperature inside our houses can also vary, especially in the winter. Most window issues arise when a fire or radiator is immediately below the window. If your radiator is beneath the window, you can shield it with curtains that fall below it. Make sure there is enough airflow from the rest of the room to the window to avoid cracks.

Preventive and Maintenance

Continual Examination

Regular inspections are essential to preventing double-glazing failure. Inspect the glass, frames, and seals for indications of damage. Early detection enables prompt repairs, avoiding expensive replacements.

Appropriate Airflow

Sustaining enough ventilation within your residence helps control internal humidity levels. In addition to this, it diminishes the possibility of condensation developing inside the double-pane windows.

Change of a Seal

A specialist can replace the damaged seals to preserve the integrity of the double-glazing unit. This procedure involves removing the previous seals, thoroughly cleaning the area, and attaching the new seals.

Glass Replacing

You require a glass repair when there is significant moisture or irreparable damage. Skilled technicians can install glass replacements. They guarantee a seal and the best possible thermal performance.

Contact the Double-Glazing Specialist

The purpose of double-glazed units is to increase a home's energy efficiency. Double glazing offers better thermal insulation. This reduces outside noise interference compared to single-glazed windows. It could be a wise investment to replace your double-glazed windows if you discover that they aren't functioning as well as they once did.

Visible condensation, air and water leaks, chips and cracks, and an increase in outside noise are the primary indicators. If you see any of these symptoms immediately, replace your double-glazing window. With its increased durability and insulation, new double glazing can save energy costs. This also helps to improve your house's comfort level.
