What Are Double Pane Windows? Differences, Costs, & Benefits

Many of our customers overlook a simple measure to effectively warm their homes and reduce their electricity bills: double pane windows. Installing double-pane windows can provide many benefits to your home. 

Double pane, or dual pane windows, are windows with two panes of glass glazed to the movable part of the window (sash) and placed in the window’s frame. The glaze insulates the window, and in turn, your home. 

People with older homes should strongly consider the upgrade to double pane windows. Why are double pane windows better? Allow me to explain. 

What Do Double Paned Windows Do?

Double pane windows have a small space between the two glass panes that creates an air pocket. This air pocket keeps the outside elements from affecting the temperature inside of your home. This air space also contains a desiccant that prevents condensation from forming. 

The more energy-efficient windows have argon gas fill between the panes for extra insulation. Argon is a clear, slow-moving, odorless gas that significantly greatens thermal efficiency. 

The large difference between single and double pane glass is the structure. Single pane glass has one pane while double has, you guessed right, two panes! A single pane window costs less, sure, but your heating and A/C bills are going to be steep. You are looking at saving roughly 20% to 30% with double pane windows. Over time, the savings are significant. 

Windows are often the main source of temperature loss for a home. If you have old single-pane or poorly installed windows, you are racking up the electrical bill with little to show for it. If you are not thinking of the long-term picture here, you are going to pay for it quite literally. Over time, double pane windows will pay for themselves, with returns of around 80%

An extra pane of glass also means extra sound reduction from outside noise resulting in a quieter home. Cut down on noise pollution from car engines, loud children, and those noisy squirrels and birds. 

Do double pane windows need storm windows? Luckily for us, they do not. Double pane windows remove the nuisance of putting up and taking down storm windows, an arduous task come spring and winter. The need for extra protection from summer and winter temperatures is therefore removed. Beyond this, think of all the time saved from having to do this year in and year out!

Double pane windows are available in many beautiful styles such as single hung windows, horizontal sliders, and fixed picture windows. Installing dual pane windows in your home will be sure to provide you with a quieter, happier environment for you to enjoy. 

Going Green

When I talk about going green, I am not talking about solar panels and wind turbines here. The average American household spends $1,500-2500 on energy bills and 45% of that cost is for heating and cooling. The National Fenestration Rating Council (NFRC) labels are an effective measure of how well a product can retain heat inside of a room, how much air will enter the room through a product, and other important qualities. 

TNT Home Improvements prides itself on providing quality Amerimax window installations in the Loveland, CO area. These windows have excellent NFRC ratings and meet or exceed Energy Star requirements in all climate zones. Beyond that, they are beautiful to look at.

Your Individual Carbon Footprint

Home energy use comprises a huge chunk of your carbon footprint, with estimates that this eats up around 27 percent. It is estimated that replacing single-pane windows with double-pane windows will save on average up to $465 per year.  

Window Films

Window films can be applied to a window after installation. Solar control window film is designed to reflect UV rays. If you want non-reflective and have the cash, ceramic film is an option and is suitable for all climates. Dual reflectivity film allows you to clearly look out your window at night instead of staring at your own reflection as you would see with standard reflective solar control films.

60% Of All U.S. Homes Have Double Or Triple Pane Windows

It is estimated that over 118 million American homes have double or triple-pane windows. This makes up 60 percent of all U.S. homes. However, that means 40% of homes are using old, inefficient technology. Single pane windows can be appealing with the low price tag upfront, but the homeowner will spend much more on utilities with this approach in the long run. 

Improving Double Pane Window Efficiency

Windows are a significant point of energy loss in a home. Here are a few tips to help improve window efficiency:

  1. Use Thermal Curtains: Thick thermal curtains provide great insulation.
  2. Add Window Insulating Film: Thin, clear plastic film will slow thermal loss.
  3. Weatherproofing: Older windows may be opening around the framing. Exterior-grade silicone caulk will take care of this. 
  4. Replace Foggy Windows: Foggy windows between the two panes have faulty seals and gas has leaked. Either the window sash or the entire window will need replacement. 

Why Are Double Pane Windows Better? 

Double pane windows save money and can reduce energy usage by up to 24% during the winter and 18% during the summer compared to single-pane models. With some top-of-the-line models, you can expect up to 50% energy savings. Double-paned windows are good for the environment, and they significantly reduce outdoor noise pollution, especially in busy, urban areas. 

Cons Of Double Pane Windows

There are not really any inherent cons to double pane windows. However, poor window quality and installation can certainly impact your expected energy savings. Ultimately, you get what you pay for! Failed seals or windows that fail can lead to condensation between the panes and other issues. Another downside is that you do not really get the sought-after benefits unless you replace all your old windows. Replacing one window will not change a whole lot. You still have all those other old, inefficient windows, well, being inefficient. 

Poor Installation or A Cheap Product Will Cost You 

Have double pane windows that, despite cleaning inside and outside, remain cloudy despite your efforts? There is a good possibility that you may have condensation. This forms inside double pane windows when the desiccant in the air space between panes becomes saturated. Double pane windows have a thick sealant around the edges. Gradually, warm air (holding more moisture) seeps into the air space and releases moisture as it cools. The desiccant absorbs it until it eventually does not work. At this point, the glass units need to be replaced. 

Cloudiness is a visual issue, not having a huge impact on energy efficiency, but if budget allows for it, consider the switch to double pane. 

The Economical, Environmental-Friendly Choice

Opting for double pane windows, while more expensive upfront, will save you a lot on your annual energy bill and is an environmental-friendly choice. If you do not have quality products that have been installed by established professionals, you are taking a big risk (think leaky sealants, cloudy windows, and noise pollution). Windows are often the main source of energy loss for a home and making the decision to purchase double-pane windows can make a huge difference.

Give Your Rooms a New Look with Window Replacements in Loveland

What do you first consider while decorating your room? You plan to bring new fixtures, paint the walls, and add suitable lighting. Most people forget that windows are also a crucial element of their rooms. Windows can transform your room to a great extent. Old windows with broken hinges or tainted glasses don’t usually accentuate their beauty. This calls for immediate window replacements so that you can get rid of the old and dilapidated windows. That’s when you need to consider hiring us. We can replace your old windows with new and stylish ones.

Importance of window replacement

Windows are very versatile for any room. They add not only natural light to your room but also ensure constant ventilation and entry of fresh air. Apart from these things, windows also contribute to your room’s energy-efficiency and overall curb appeal. Having said that, it is essential to have quality windows to enjoy these benefits. Windows with broken seals and glasses will not offer so many things. That’s what makes window replacements necessary.

Window replacement in Loveland

Our company offers a variety of window replacement services in Loveland. From replacing old windows to installing new ones, we are ready to make your rooms look beautiful again. Over the years, we worked with tons of different windows. This allowed us to gain more experience in this field. Nowadays, we can work on any type of window in Loveland.

Window replacement process

We follow a simple window replacement process that works for almost all the windows.

• We start with the new window’s nailing fin. This rim allows us to secure the window in the wall’s opening. However, replacement windows don’t have these fins. Therefore, we secure the replacement window in your existing frame. We use fasteners that run through the window’s assembly, thus making it easier for us to install the new window.
• Sometimes we need to change the entire frame also. We come equipped with all the necessary tools to slowly take down the old frame before replacing it with a new one. You can go through some of the window frames before hiring us. We will come and take the measurements of your existing window, along with its openings. Accordingly, we will resize the frame and install it in your room.


Types of windows

As already mentioned, we work with almost every type of window you can think of. We have had the opportunity to work with tons of different windows in the recent past. Here are some of the most common windows we came across in Loveland.

Single-hung windows

Single-hung windows have an operable lower sash that allows you to pull it up. Some models also allow you to pivot the sash inwards so that you can clean its exterior easily.

Double-hung windows

These windows provide a classic look to your room. Both the upper and lower sashes are operable. You can raise the lower sash to allow cool air to come inside and lower the upper sash to let warmer air enter the room. Many double-hung windows also have tilted inward sashes, allowing you to clean their exteriors easily. We often see these windows on houses with a second story.

Sliding windows

Sliding windows have become widely popular in recent times. They are cheaper to install, easy to operate and require low maintenance. However, the windows operate on a slider with a fixed path. The windows will not operate if the path has a dent. These windows may have one or multiple panels, depending on their size. You can slide and open the panels for ventilation. We can replace your old single-hung or double-hung windows with sliding windows. However, we will need to change the frame. You can even hire us to install brand-new sliding windows.

Basement hopper windows

You may often see windows tilted inwards in many basements. They have hinges on the bottom. You need to push the window inwards to open it. These are basement hopper windows. They look like the lower sash of single-hung windows, only bigger. We can install and replace basement hopper windows in no time. They don’t require a lot of tools and machines for installation. Their frames look solid. We advise you to go for wooden frames as they last longer. Many manufacturers also provide aluminum frames. These have become a cost-effective alternative to wood.

Glass block windows

Glass block windows are ideal for bathrooms. They are made using individual blocks sealed together. These windows have thick, break-resistant glass that offers privacy, but also allows light to come inside your bathroom. But remember, you cannot open glass block windows. Once we fix them to the wall, you cannot move or open them. Some of the modern glass block windows have built-in vents allowing ventilation. We can install new windows and replace existing windows with glass block variants.

Apart from the top five, we also have experience in installing various other windows, such as projection windows, casement windows, picture windows, storm windows, skylights, and awning windows.


Our window frame materials

We pay a lot of attention when it comes to finesse and quality of window frame materials. The frame material affects various factors, such as durability, maintenance, and heat transfer, making it one of the essential components of your window. We make sure that your window has the best frame so that it lasts longer. Here are some of the frame materials we use:

• Vinyl

It is one of the most common window frame materials made from impact-resistant polyvinyl chloride. Vinyl has hollow chambers on its inside that helps to resist condensation and heat transfer. It is ideal for rooms where you want more warmth. These window frames don’t require additional finishing or painting. The frame lasts for years without signs of fading or rotting. We have used vinyl frames in hundreds of houses in Loveland. They are best for replacement windows.

• Aluminum

Aluminum is an economical option. They have many advantages: first, they are a cost-effective option. Second, they are easy to install compared to other window frames. Third, they are light and durable. They can last for years without requiring too much maintenance. Like vinyl, aluminum also doesn’t require additional finishing or coloring. Plus, aluminum frames are corrosion-resistant, making them ideal for areas that experience heavy rainfall.

• Wood

Wood is a popular material prevalent in Loveland. However, we advise you to use it on the interior parts of your window. Loveland experiences moderate moisture throughout the seasons. Wooden window frames can rot if they absorb moisture for long periods of time. Moreover, wood doesn’t conduct cold or heat like other materials. It also doesn’t allow condensation. They come unfinished. However, there is no match to wood’s finishing. It may have several downsides, but when it comes to using a classy window frame material, everyone will agree that wood stands apart.

• Clad-wood

Clad-wood looks similar to wood and provides all its benefits, but offers additional protection on the exterior. It uses a low-maintenance aluminum jacket to keep the window frame and panels safe. Most importantly, the cladding in these frames prevents them from rotting and makes the exterior durable. Clad-wood a good option for new windows.
