What are Double Glazed Windows?

A double-glazed window, also known as a double-pane window, is a window that consists of two panes of glass with an air space between them.

Between the panes of glass is an inert gas which helps to prevent moisture between the panes of glass.

Double-glazed windows help to reduce the amount of noise that passes through the windows. Double-glazed windows are generally affordable and come in many different shapes and sizes.

Winds from the outside can encouraged air escaping through the window during the night, especially when the window is left open.

Double-glazed windows can be available to suit a wide variety of budgets.

Double-glazed windows are constructed of four different materials;

  • Glass
  • Aluminum
  • Nylon and PVC
  • Polycarbonate

Advantages of Double-Glazed Windows

1. Energy cost savings.

Thermal insulation is created by the airtight construction of double glass windows. This decreases the flow of heat both entering and leaving.

Less energy is required to heat or cool the area, which results in cheaper energy costs.

Adding a third or fourth pane of glass to your window improves its insulating value.

Each layer of glass retains a substantial quantity of heat that goes through, improving the window’s heat loss protection.

The thermal insulation created by double glazed windows also allows you to reduce your heating costs, which help save you money on your energy bill

2. Improved comfort levels.

Double glass windows are generally quiet, and the air space creates a buffer between the panes of glass and the outside world.

This reduces or eliminates noise transfer from noisy streets, for example, and provides a quieter environment.

3. Improved sound quality.

Double glass windows reduce the amount of airborne sound that makes its way indoors.

This is because of their interior air space that acts as a buffer and absorbs airborne sound passing through them instead of reflecting it back to the area surrounding the window’s interior.

4. Improved protection from the sun’s ultraviolet rays.

Double glass windows reduce ultraviolet rays that pass through them by more than 75%. This is because UV is largely absorbed by the gas and glass, meaning it cannot reach your skin or anything else inside.

5. Protection against extreme weather conditions.

Double glass windows can protect you from extreme weather conditions, like snow and hail storms, as well as heavy winds and rains.

This is because air is able to pass through the glass and as an insulating material, it stops heat from entering or exiting your home.

6. Protection against cracking or warping of siding or trim.

Double glass windows can help protect your exterior home façade from damage caused by high winds.

The air space will act as a buffer to the wind and can help protect the most vulnerable areas, like jutting pieces of wood.

7. Protection against water damage.

Double glass windows are highly resistant to water damage, which means that they do not crack or become warped from heavy rain or other elements that cause water to accumulate inside or outside of your home.

8. Better Security

Because double-glazed windows are more difficult to shatter than single-pane windows, they improve house security.

Because they are more well sealed than conventional windows, forcing them open from the outside is more difficult.

9. Property Value Increase

As you can see, adding double glazing improves and makes your home more comfortable to live in.

When compared to a property with single glazed windows, this makes the house more appealing to potential buyers.

If you ever need to sell your home, you can be confident that you will obtain a greater price than you would with single glazing.

10. Aesthetics

Double glazing is an excellent method to improve your home’s curb appeal.

Today, any architectural features may be equipped with double glazing without affecting the house’s original appearance and feel.

You can ensure a beautiful look by hiring an experienced and trained professional to install your double glazing.

Disadvantages of Double-Glazed Windows

1. Higher cost of installation

The cost of installing double glass windows is very high; however, this may be offset by increasing the value of your home through improved energy efficiency.

2. Complex installation process

Most double-glazed windows are crafted to perfection with special equipment, and it is, therefore, necessary to hire a professional for the job.

3. Limited warranty coverage

Installing double glazed windows requires highly specialized skills and experience, so you should always check with the window manufacturer about any relevant warranty coverage for the product.

Double Glazed Windows FAQs

1. What are the advantages of double glazing?

Double glazing insulates your home. It allows you to keep your house cooler in moderate climates, and warmer in colder areas.

The gas fills the air space, increasing the insulation between the glass panes. When compared to single-glazed windows, double-glazed windows are up to 30% more effective at reducing heat loss or gain.

Double glazing functions similarly to woolen garments and fiberglass batts.

2. Do double glazed windows make a difference?

The difference is not immediate, but it does increase over time. As the windows become more and more used, the differences become more obvious.

Double glazing may improve your home’s insulation by up to 73 percent while also reducing noise by up to 70 percent.

However, if you have single-glazed timber windows, you may have the same insulation, acoustics, security, glare reduction – and less moisture – for roughly one-third of the cost of new double-glazed windows.

3. Are double glass windows good for security?

Double glazed windows are hard to break through, which makes them good for security purposes.

4.  Is it worth getting double glazed windows?

5. Is it a good idea to have double-glazed windows?

Double glazed windows are an excellent alternative for energy efficiency and noise reduction. The air gap between the two panes serves as an additional layer of insulation.

This increased thermal resistance decreases heat loss in the winter and maintains your house at a more pleasant temperature.

6. How long do double glazed windows last?

Double-glazed windows have a lifespan is estimated to be anything between 20 and 35 years depending on the supplier and the fitter.

The lifespan of double-glazed windows also depends on several factors, like the size of the window, the type of glass, energy efficiency rating, and whether you have aluminum or uPVC frames.

7. What is Triple Glazed Windows?

A triple glazed windows is a window with a more advanced glass design that increases energy efficiency and reduces sound by over 50%. It has 3 panes of glass instead of 1.

8. Is triple glazed windows better than double glazed windows?

Triple-glazed windows offer the greatest energy savings because the air space is greater in volume.

The result is that they have more thermal resistance, which means that they can keep your house warmer in winter and cooler in summer.

This can save you up to 40% on heating bills over the course of one winter.
