Materials Used to Make Replacement Windows

  1. Vinyl

Windows made of vinyl are increasingly becoming more popular over other common materials such as wood. Today, more windows made of vinyl are being sold when compared to other materials. Vinyl windows make up to 67 percent of windows ordered for replacement.

They’re mostly used due to their affordability, dependability, energy efficiency, and durability. These windows are almost maintenance-free. They resist rotting, scratches and warping. Vinyl has the benefit of being good at insulation, making it a great material for making windows.

Other special features may be added such as filling the gap between panes with argon gas and attaching the panes on a vinyl frame to enhance the energy efficiency of the window.

It’s recommended to avoid staining or painting vinyl since the paint will not stick well. Painting may also affect the frame’s insulation capabilities. Due to this issue, they come pre-painted in a desired color or finish when making an order.

These windows are also customizable. You can have them shaped to perfectly fit any opening. They also come with many colors to choose from for the inside and outside frame. If you want to get a dramatic look, then you can choose faux wood finishing. White is also a common choice.


  1. Wood

Another popular window material is wood. It’s preferred for its multiple benefits such as beauty and energy efficiency. Wood has superb insulating capabilities.

Today, there are several materials and techniques used to ensure that wood no longer has the problem of getting drafty.

Unlike vinyl, wooden frames may be stained or painted as needed, and they can be styled to blend any look of a home. Wood stands out as a great material for homeowners who desire to give their home a classical touch of style for enhanced warmth and beauty.

The challenge that comes with wooden windows is that they are not durable. They’re vulnerable to rotting, insect infestation and warping.

Moreover, wood does not do well in environments with extreme weather conditions, thus you should be ready to do regular repairs in case of any issues. Due to the maintenance it demands, wood is ultimately costlier than other materials.


  1. Fiberglass

Fiberglass is not commonly used and most homeowners overlook it, but it comes with great benefits. For instance, windows made of fiberglass are almost maintenance-free and are durable. Fiberglass does not rot, warp or swell and has more benefits over other materials such as vinyl.

Fiberglass boasts of being stronger and tougher, thus it withstands tear and wear. These frames may be painted in any color and may come with a wooden exterior and interior finishing that makes them look like wood. Moreover, fiberglass is more affordable than wood, but more expensive than vinyl.


old windows replaced with aluminium and glass windows


Aluminium Windows

Windows made of aluminium are least common among homeowners. However, they still have some benefits that other materials lack.

Aluminium is extremely strong and may be comprised of a thin, durable frame. Thin frames allow for wider glass panes such that you can enjoy wider outdoor views and more natural lighting.

Windows made of aluminium come in multiple colors and are long-lasting and tough. However, there are some shortcomings about aluminium that cannot go unmentioned. Aluminium is metallic, thus poor at insulation.

It doesn’t keep cold and heat away from entering your home. Also, aluminium contracts and expands easily under extreme weather conditions.

Due to these shortcomings, most homeowners prefer going for modified versions of aluminium windows that comprise of a wooden core dressed in aluminium. Even though a modified version comes with better insulation, other materials are better at insulation.


Energy Efficiency of Replacement Windows

Most materials that make windows are good insulators, thus they are energy efficient. However, extra features may be added on the windows to further increase their energy efficiency. This way, you will enjoy reduced energy costs.


Low-Emissivity Glass

Glass classified as low emissivity (or Low-E) refers to glass that is treated using an invisible coating of metallic oxide. The result is a glass surface that allows natural light into a room while reflecting heat.

Low-E type of glass enhances energy efficiency and makes the home more comfortable throughout the year.


Argon Gas

Energy efficiency is also enhanced through argon gas. This gas is non-toxic, clear and odorless. It is used to fill the gap between double-paned or triple-paned glass windows. It minimizes heat transfer through a window such that heat won’t escape during winter or enter during summer. Therefore, your home will be comfortable no matter the season.



Another material that enhances energy efficiency is caulk. It’s flexible and is used in sealing air leakage through gaps and cracks in the window frame. Applying caulk is effective in increasing energy efficiency.

If these openings and cracks are not caulked, cold air can escape during summer and warmer air can escape during winter. Hence, caulking reduces over-reliance on air conditioners and heaters, thereby reducing energy bills.


Weather Stripping

Enhancing energy efficiency through weather stripping can be compared to caulking. It’s done just like caulking. However, the weather stripping technique is applied on operable window parts such as the sash window while caulking is used on stationary parts such as the frame.

Materials used for weather stripping include foam, sponge, vinyl or felt. These materials can also be combined to make weather stripping. No matter the material used, this technique offers similar techniques like caulking.

It fills any gaps around the frame and other moving parts, thereby preventing air from passing through the window once it is closed. This way, cold air will be kept out during winter and warm air will be kept out during summer.


Cost of Buying Replacement Glass Windows

There are several factors that determine the overall cost of buying new windows. They include features that come with the window, style and the material.

Vinyl windows tend to be the most affordable option, with aluminium and fiberglass being the average priced option. Wooden windows are costlier than other options.

The amount or size of the material used in constructing the window has a huge impact on the price. If your window openings are large, you will pay more for new windows.

The size of glass making the window will also affect the pricing. A wider or thicker glass pane will push the price higher.

Adding extra features such as filling the glass with argon gas or treating the glass to make it Low-E will also drive the cost up. Any extras you make on a standard window will surely make it more expensive.

When making considerations about the cost of buying replacements, you should remember labor costs for installation. Some homeowners may want to install windows on their own to reduce the overall cost of installation.

Installing them on your own will eliminate labor costs. However, hiring a professional window installation company comes with an extra cost of labor.


Window Installation Process

Installing New Windows on Your Own

Replacing your older windows with new ones demands some skills. The skills required may vary. They depend on the kind of replacement project at hand.

If you’re installing fully framed windows, the entire process will demand more skills for it is more complicated to install such windows than installing insert replacements. Full-frame window installation means that you will completely tear out the existing window and replace it with a new set.

With an insert window installation, you will simply insert the new window onto the existing frame, thus, you will not tear out the existing frame.

Besides the skills required, you will also need some tools when doing it yourself. The tools necessary for DIY window replacement include:

  • Safety glasses
  • Screwdriver
  • Level
  • Tape measure
  • Pry bar
  • Caulk gun
  • Hammer
  • Power drill
  • Utility knife
  • Putty knife

Once you have the necessary tools ready, you will need to set aside enough time for the entire installation process. Replacing full-frame windows may take between 4 to 6 hours for a single window at the ground floor.

Replacing full-frame windows on higher floors, such as the 2nd floor, may take longer and you will need a ladder to reach windows in higher floors.


Professional Window Installation

Although you might get tempted to buy and install replacement sets of windows on your own, DIY is never recommended for homeowners who don’t have the required skills based on several reasons.

For instance, if you choose to install windows on your own, manufacturers and window dealers may not offer you a warranty.

The reason behind this is that something might go wrong during installation or when using a poorly installed window due to your own inexperience and errors. Hence, most brands don’t offer labor warranty for DIY window replacements.

Professional window contractors are trained and experienced to spot any issues that your home’s foundation or drywall might have.

Professionals will inform you whether they should do any extra repair work before installing new windows. Such details are missed by inexperienced DIY enthusiasts and doing replacements with such problems may cause more problems in future since they were unnoticed early enough.

Moreover, inexperienced DIY enthusiasts may damage the new windows during installation or even damage the walls. Replacing your older windows yourself is also dangerous.

For instance, you might break costly glass panes and they may cut you. Replacing windows on higher floors is also dangerous since you will have to climb ladders and there may be risks of falling off the ladders.

Hence, installing new windows should be left to the professionals. Only professionals have the skills, tools, knowledge, and experience required to install windows properly and safely.

When windows are installed professionally, everything is done the right way and you will maximize on the benefits that you are looking for in new windows.
