Dormers create more space under angled roofs and make it possible to have windows in those spaces for natural light.
These days many houses incorporate fake dormers for the aesthetics, but some new houses make them real.
B. Window Panes
1. Double Pane
Double Pane is the most common type of window pane. It has two sheets of window pane glasses that are separated by trapped gas (commonly krypton or argon) in the middle. The gas makes a tight seal which holds the window more firmly, which prevents heat and energy loss inside the house.
- These type of windows prevent condensation on your windows, especially during winter.
- Provides good insulation.
- Because of the creation of a tight seal, this type of windows help block outside noise.
- Increased security and durability.
- It may not be a good match for old, ancestral homes.
- Maintenance is costly since it can’t be repaired once broken–you need to replace the entire thing.
- Having such a great insulator, is not a very good news during summer season.
2. Triple Pane
Due to architectural advancement and breakthroughs, the triple pane window is becoming more and more popular recently. Unlike the double pane windows, it has three sheets of window glass pane, separated by 2 separate layers of gas. This 2 layers of airtight gasses provides improved insulation than the double pain.
- Triple pane windows are the improved versions of the double pain. So to make it short, it is the improved and better version of all the advantages/pros of the double pane–better insulation, better sound proof and lower condensation during winter.
- It is more expensive than the double pane.
- Heavier than double pane, so it needs more durable window sash/frame.
3. Quadruple Pane
The quadruple pane window is by far, the most advanced type of window pane right now. The insulation is made even better by combining 4 sheets of window pane glass with three spaces filled with gas that are airtight. It significantly raises the functionality and features of the other two type of panes mentioned above. It is better in all the pros and advantages of all the panes listed above with the con of being super heavy weight and needs a tougher, more durable window frame and sash. Not to mention the more expensive price!
C. Types of Window Frames
Now that we were able to cover the types of windows and window panes, let us now discuss the structure that support and put them all together–the frame! depending on your needs and preferences, here are the most common types of window frames to choose from!
Wooden frames are the most popular ones used in most houses up to date. It has the aesthetic appeal and classic appearance. It is used for years, not only in the window frame industry, but in the entire architectural industry because of its known beauty and durability.
- Easy to own, fix and replace.
- Durable and long-lasting if well-maintained.
- Beautiful to look at.
- Requires maintenance.
- Can be a good target of insects and termites.
Vinyl window frames are made up of polyvinyl chloride (PVC’s). It is the same materials widely used in plumbings and pipes. This is a popular type of window frame due to its durability and affordability.
- Low on energy cost.
- Versatile material which can easily made into various window styles and designs.
- Low maintenance.
- During extreme heat conditions, vinyl colors will fade which needs to be totally replaced since it can’t be repainted.
- Low resale value.
Aluminum windows has been used in classic as well as modern architecture. This is because of its durability and longevity.
- Outperforms wood and vinyl in noise abatement.
- Low maintenance. It doesn’t shrink, split, fade and rust.
- Easily matches classic and modern architecture.
- Although cheaper than wooden frames, it costs more than vinyl and fiberglass.
- Not very efficient as an insulator. It also absorbs cold, which is not very ideal for winter.
Although fiberglass type of window frame is not so common, it is still known to be the most durable and low maintenance among the four types. This frame is made of extruded fiberglass sections and formed into a frame. The outcome appearance look similar to a PVC window frame.
- Though they look similar, fiberglass frame can be repainted and is far more durable than a PVC frame.
- Low maintenance.
- Best insulator frame.
- Sound resistant.
- Though far more durable and efficient, it still looks like a PVC frame so some homeowners would prefer the later because this type of frame is more expensive, if not the same price as the wooden frame.
D. Frequently Asked Questions
Below are answers to commonly asked questions about glass windows.
How long do glass windows last?
Glass windows are fairly long-lasting but can last even longer with proper maintenance and care. The average time for glass windows to last is between 15 and 20 years without extensive maintenance and up to 30 with proper care. The lifespan of your glass window is also affected by the type of area in which you live and whether or not there is a significant amount of tumultuous weather (i.e. thunderstorms and snow). However, the type of frame you use also has a huge impact on the lifespan of a window.
For example, wooden frames can last for 10 to 20 years on average but have been reported to last up to 30 years. Aluminum frames last even longer, ranging between 15 to 40 years. Vinyl frames are arguably the most durable, lasting anywhere between 20 and 40 years with proper care.
Can glass windows be painted?
Yes, but you must make sure that you have the correct type of paint. For example, acrylic paint can be useful for not only decorating your window, but also making the window itself more durable. In order to allow the paint to increase the lifespan of your window, you should get acrylic paint that has a baked-on capability. The feature might not be labeled as such, but you’re essentially looking for something that will become harder when exposed to direct sunlight.
Can glass windows crack on their own?
Yes, glass windows can crack on their own. However, it’s more nuanced than you might think, being caused by a variety of causes. The phenomenon is referred to as Spontaneous Glass Breakage and is usually the result of how the glass was tempered or installation errors. It is difficult to tell if there is a problem with the glass, though, as it typically cracks spontaneously at random or in tumultuous circumstances. If you want to prevent your glass windows from breaking, we recommend that you read up on Spontaneous Glass Breakage so you can be aware of the risks and be properly prepared.
Can glass windows be repaired?
Glass windows can be repaired, but the specific type of repair necessary will depend on just how severe the damage is. For example, it is possible to look at small cracks in a window and reinforce the glass so it does not break any further, while larger cracks may require the entire window to be replaced. If you are unsure about whether or not your window needs repair, it’s important to do your research and consult a professional for their opinion. If you don’t do this, you put yourself (and your window) at risk!
Are glass windows load-bearing?
Whether or not glass windows are load-bearing depends on the specific type of frame and brand you purchase. Aluminum glass windows are not load-bearing, meaning that you should exercise caution when looking into those specific types of windows. However, there is no surefire way to tell if the windows you’re looking into are load-bearing. If you want to be absolutely sure, consult a professional and look for products that specifically advertise load-bearing capabilities. After all, the ones that are load-bearing will definitely advertise that!
How are glass windows made?
Glass windows are typically made by melting various minerals. The temperature for the melting process is often so high (around 3090 degrees Fahrenheit) in order to melt the specific components into one substance. The most common element in glass is often silica, a compound that is also often found in sand.
Once the compounds are all mixed into one liquid, limestone is added to the mix in order to make sure it does not dissolve. The addition of limestone results in glass forming, with this molten glass being shaped into various objects. In the case of windows, the molten glass is molded into window shapes to be sold after it properly cools down. It’s worth noting, though, that this process will change slightly depending on the specific kind of glass that you’re making and which types of materials you’re using. If you want to learn about how the creation process differs depending on which type of glass you’re making, we recommend this article.
Can glass windows be resealed?
To put it simply, yes. However, if the crack is too substantial to be resealed, it isn’t very likely that it is possible. To understand whether or not the window you want to fix is resealable, you should contact a professional to get a proper estimate and evaluation.
Can glass windows be recycled?
In the United States, it’s far less common that glass windows can be recycled. Contrary to popular belief, not all types of glass are made the same, making certain recycling facilities not interested in having to sort through glass windows. The reason why glass windows are often different from bottles and other types of glass that you should recycle is that the glass is treated, making it difficult to break up and subsequently to recycle.
However, this does not mean that you shouldn’t try to recycle windows if you have the chance to. There are organizations that have been specifically created to help people recycle windows properly and we recommend you look into one of those facilities in order to recycle your windows properly. Another recommended option for those looking to recycle glass windows is to consider ways in which you can reuse your windows, whether it be through repairing them first or installing them in a context that works. Theater companies are also always on the lookout for functioning props, so—even if you can’t use your cracked window at home—perhaps your window can become part of a new play!
Can used glass windows be sold?
Yes, but it is often tricky to sell glass windows at any comparable market prices. The only situation in which someone would actually want to purchase your glass windows is for historical preservation purposes, so it’s unlikely that someone will take you up on it. However, if you happen to have a glass window that is of significant historical value, it is likely possible to sell it to a local shop! Even if the windowpane itself isn’t usable anymore, you can likely still sell the frame for a good amount of money.
Are glass windows insulated?
Not all of the time. The insulation process that makes it possible to properly regulate the temperature of a room is typically achieved through the glass making process. So, if you want to have windows that are truly insulated, it’s important to make that a goal of your window shopping from the beginning. If you don’t take this first step, you might end up with windows that have too many spaces for air and subsequently don’t insulate very well. However, this doesn’t mean that you can’t insulate windows on your own if you want. If you want to try insulating your windows, there are plenty of options available on the internet and we recommend you do some research before committing to one. If you want to make sure that you’re doing it properly, always get the opinion of a professional.
Are glass windows soundproof?
Not necessarily. Though there are some glass windows that are specifically constructed to be soundproof, this is not the case for all glass windows. If you are somebody who wants to have soundproof windows, you should search for a brand that advertises this feature. It’s almost impossible to soundproof windows that have already been made due to the way the glass is constructed, so you will have to seek out this help as an additional step of the process. Though there may be guides that claim to help soundproof any type of glass window, they are often incorrect and misleading.
Are glass windows waterproof?
Not inherently. Though water technically bounces off of glass windows, windows that do not have proper frames might be more susceptible to damage during more tumultuous weather conditions such as flooding, hurricanes and thunderstorms. If you want to try out a type of window that will hold up in poor conditions, we recommend looking into glass block windows. However, to ensure that you’re installing any windows you purchase properly, you should enlist the help of a professional. If you don’t, you run the risk of your windows not being truly waterproof!
E. Window Buying Guide
Now that you have a good understanding of your window options, what else should you look for. Here are some tips.
- ENERGY STAR and NFRC labels: Energy Star label means your windows meet the EPA’s minimum standard for insulating in your area.
- In colder climates, consider gas-filled windows with low-E coatings to reduce heat loss. You can also get a low U-factor for better thermal resistance. U-factor is the rate at which window conducts non-solar heat flow.
- In warmer climates, choose windows with coatings to reduce heat gain. Look for low solar heat gain coefficient (SHGC). SHGC is a measure of solar radiation admitted through a window. Low SHGCs reduce heat gain in warmer climates.
- In climates that are both hot and cold (i.e. have seasons), get windows with both low U-fctors and low SHGCs.
