Pros and Cons of Double Pane Windows Complete Guide
We are greeted with many window types when we talk about window options. No doubt, each window has something unique to offer. But if we talk about double-pane windows, they offer a lot of special add-ons.
For instance, they are quite durable. Moreover, they also don’t require frequent maintenance. Like these points, there is a lot more to like about these windows. This blog post is all you need to know about double-pane windows and their applications. So, let us get into it!
What are Double Pane Windows?
Also known as dual pane windows, double pane windows are windows that have two layers of glass separated by a small space, usually filled with air or an inert gas such as argon or krypton.
This design helps to insulate the window, making it more energy efficient and reducing heat transfer between the inside and outside of the building.
The space between the panes also helps to reduce noise pollution and increase the overall durability of the window.
Pros and Cons of Double-Pane Windows
Here are a few of the pros and cons of double-pane windows.
1. Offers Great Insulation
Double-pane windows are best known for offering excellent insulation. That’s because these windows have two layers of glass separated by a spacer. The space between the glass panes is filled with air or an inert gas, such as argon or krypton, which acts as an insulator.
This improves the window’s thermal performance, reducing heat loss in the winter and heat gain in the summer, making them more energy efficient than single-pane windows. Further, it helps a lot in reducing energy bills by a significant margin.
2. Sound Proofing
Double-pane windows can also help reduce the amount of outside noise that enters a building by creating an airtight seal between the two panes of glass. The air trapped in between the panes acts as a barrier to sound waves, helping to reduce the transmission of noise into the building.
Moreover, the use of Low-E coatings, which are applied to the inner surface of one or both panes of glass, can also improve the sound insulation properties of double-pane windows.
3. Increases the Property’s Value
Even if you have no plans to sell your home, opting for double-pane windows is recommended. That’s because these windows will serve you for a long period. Further, at some point, if you plan to sell your property, you will get a better return on investment with these windows.
Potential buyers prefer quality home windows that are energy efficient. In this regard, the double-pane windows really stand out because of their insulation properties.
4. Enhanced Durability
The durability aspect of these windows is quite obvious. Since these widows have two glass panes, they are quite durable. Because of their durability and strength, these windows can easily last for years.
So you won’t have to replace them every now and then. Moreover, they also don’t require hefty maintenance.
5. Easy Customizations
Homeowners like to customize their home windows. In this regard, a double-pane window won’t disappoint you. That’s because you can order them in any size, thickness, etc. Furthermore, you also have the option to choose the type of glass of your choice.
1. A bit Expensive
Double-pane windows are a bit on the expensive side. Now, you definitely have to pay an extra cost to get all those benefits. However, in the longer run, the additional cost does get justified.
Applications of Double Pane Windows
Now, let us explore a few areas where double-pane windows are widely used. Here are a few of its applications.
1. Residential and Commercial Properties
As we just highlighted above, these windows have become a hot pick for every homeowner. Simply because these windows are energy efficient.
Even in commercial properties, double-pane windows are widely used. Everyone wants to save the maximum on energy bills. So, opting for these windows has become quite common these days.
2. For RV Camping
A lot of people are into RV camping. It helps them explore different areas in a unique style. Now for extensive touring, travelers need a durable RV van. Therefore, double-pane glass windows are also used for RV vans.
What to Look for While Buying Double Pane Windows?
Once you know the benefits of these windows, it should become easier for you to buy one. In case you are confused, here is a brief buying guide for your ease.
U-Value is an essential thing to look for in these windows. This measures the window’s ability to insulate, with a lower value indicating better insulation. In short, U-Value is a measure of the rate of heat transfer through a material and is an important factor to consider when buying double-pane windows.
The lower the U-Value, the better the window is at insulating and preventing heat loss. Look for windows with a U-Value of 0.3 or lower.
2. SHGC (Solar Heat Gain Coefficient)
The Solar Heat Gain Coefficient (SHGC) is an important factor to consider when buying double-pane windows. The SHGC measures how much solar radiation is allowed to pass through a window and how much is reflected or absorbed.
A lower SHGC means that less heat is allowed to enter the room, making the room more energy efficient and cooler. When buying double-pane windows, look for windows with a low SHGC, usually between 0.25 and 0.40, to reduce the amount of heat entering your home.
3. Air leakage rate
The air leakage rate is another important factor to consider when buying double-pane windows. The air leakage rate measures the amount of air that passes through the window.
A low air leakage rate is desirable as it helps to maintain a comfortable indoor environment and reduces energy consumption.
Look for windows with a low air leakage rate, typically less than 0.3 cubic feet per minute (CFM) per square foot of window area. This will help ensure that your home is well-sealed and energy-efficient.
4. Visible transmittance
Visible transmittance (VT) rate is a measure of the amount of visible light that passes through a window or a piece of glazing material. The VT rate is expressed as a percentage and indicates how much of the light that falls on the window is transmitted through it.
When buying double-pane windows, you should look for a high VT rate, which usually ranges from 0 to 100. A higher VT rate means more natural light will enter the building, reducing the need for artificial lighting and potentially saving energy costs.
5. Quality of Frame and Glazing
Look for frames that are made of durable materials and glazing that is sealed properly to prevent leaks.
6. Energy Star rating
If the windows have an Energy Star rating, it means they meet certain energy efficiency standards.
So, now you know all about double-pane windows. They are best known for their insulation properties. That is why they are a hot pick of almost every homeowner. Further, these windows also offer good sound insulation. Because of these features, double-pane windows are also used in RV vans.
Anyhow, you should always buy double-pane windows from a trustworthy glass vendor.
Frequently Asked Questions
1. What Is The Benefit Of Double Pane Windows?
Double-pane windows offer several benefits, including improved insulation, reduced energy costs, reduced noise pollution, increased durability and longevity.
2. Is Double Pane Glass Worth It?
Double-pane glass can be worth it, depending on the specific situation and needs. Some benefits include improved insulation, reduced energy costs, reduced noise pollution, increased durability and security, and improved home value.
However, the cost of double-pane windows can be higher upfront compared to single-pane windows. It is important to consider the long-term cost savings and benefits before making a decision.
3. What Is the Difference Between Single and double-pane windows?
Single-pane windows have one sheet of glass, while double-pane windows have two sheets of glass separated by a sealed space, known as an insulating gap. The insulating gap helps to reduce heat transfer and improve energy.
Further, double-pane windows can also reduce noise pollution and increase durability compared to single-pane windows. Therefore, these windows are superior to single-pane windows.
4. Are Double Pane Windows Energy Efficient?
Yes, double-pane windows are more energy efficient compared to single-pane windows. The insulating gap between the two panes of glass helps to reduce heat transfer and improve insulation, which can result in lower energy costs and increased comfort.
The specific energy efficiency of double-pane windows will depend on the materials used in construction and the thickness of the insulating gap, among other factors.
