Why Replace Your Windows?

Why Replace Your Windows in NJ

There are multiple reasons why people replace their windows. In a recent survey conducted by Window and Door Magazine the top 10 reasons to replace your windows are:

  1. Energy efficiency – One of the primary sources for energy loss in a home results from inefficient and poorly sealed windows. You can realistically expect to save 15- 20% or more on your utility bills with replacement windows. Older homes with windows that have single pane glass can realize even higher savings. With the price of energy continuing to rise, your savings will continue to compound for as long as you stay in the home.
  2. Easy Cleaning – Windows get dirty often and drastically reduce the amount of visible light in your home. The ability to clean your windows is more important than ever, especially as more of stay home for longer periods of time. Over the years, many new features have been developed to assist in window cleaning. Most double hung windows feature easy tilt in sashes which allow cleaning of the exterior glass from the interior of your home. Some casement windows crank out and over to allow cleaning for the inside. Others provide exterior glass coatings that keep windows clean for longer period of time.
  3. Low to Zero Maintenance – Today, many manufacturers offer an exterior window that requires virtually no maintenance. Other than cleaning and inspecting the caulk joints, you should enjoy many years of worry free maintenance to your windows and trim. Windows made of vinyl, fiberglass, composite material, aluminum clad wood, vinyl clad wood or all aluminum will provide you with varying degrees of low maintenance. Most will eliminate the need to paint on a regular basis which will save on your painting bills.
  4. Aesthetics – New windows can provide a new and modern look for your home. They also can match your original home while delivering energy saving benefits. Most window replacement companies offer different color choices for the exterior and hardwood interiors. Grid options can also give you an opportunity to totally change the look of your home on the outside.
  5. Comfort – Another great benefit of new windows is the reduction of cold drafts in the winter and hotspots in the house during the summer. New energy efficient windows with reflective properties help keep radiant heat inside in the winter and
    outside in the summer. This helps keep homes, especially those in climates like New Jersey, cool and comfortable all year long!
  6. Noise reduction – Double and triple pane glass, Low E coatings, Argon, Krypton gas, and modern weather stripping all contribute to a quieter home when you have your windows replaced. For those high traffic areas, laminated glass can dramatically reduce sound transmission through your windows.
  7. Safety – Today’s modern windows have easy to use features that provide an escape route in case of fire. Ease of operation, easy tilt latches and the ability to totally remove sashes can provide you with peace of mind in case of fire. Tempered or safety glass provides protection in high traffic and high hazard areas where there is danger of falling through the glass or glass breakage. For the ultimate in security protection, laminated glass can prevent or reduce the chance of break-ins and eliminate the need for security bars.
  8. Durability – High quality windows are built with the latest advances in technology. You can expect to get many years of trouble free performance, low maintenance and energy savings with quality replacement windows. Many manufacturers are now offering limited lifetime warranties.
  9. Re-sale value – New windows enhance your homes value and are one of many value rating points for appraisers.
  10. UV protection – Fading of carpet, furniture, floors, and drapes is commonplace with old windows. With new glass technology, these issues can be drastically reduced without dramatically affecting the amount of visible light transmittance.

Types of Replacement Windows in NJ

Types of Replacement Windows in NJ

There are a number of different types of replacement window options to consider. When choosing a window type, make sure to take things like energy efficiency ratings, price, maintenance, durability, strength, and color selections into account.

Wood Windows

Wood windows have been around forever and remain a popular choice for people looking to achieve a traditional aesthetic. Wood windows provide very good thermal performance overall due to natural insulating qualities.

Some neighborhoods, especially historic ones, often require that replacement windows be made of wood. When using wood windows proper weather stripping is key to prevent drafts and maximize energy efficiency.

The biggest drawback to wood replacement windows is definitely the cost. There are also a lot of “bad” wood windows out there. Pay attention to they type of lumber and make sure it’s treated after it is cut to maintain aesthetics and performance.

  • Energy Efficiency: Very Good
  • Price: High
  • Maintenance: High
  • Durability: Fair
  • Strength: Good
  • Color Selection: Very Good

Wood Clad Windows

Wood clad windows are a good option if wood windows are desired but maintenance is a major concern. Cladding is typically an aluminum or vinyl protective cover that shields the wood exterior from weather but leaves the natural wood exposed on the inside.

There are 3 types of wood clad windows to consider:

  1. Extruded aluminum clad windows
  2. Roll formed aluminum clad windows
  3. Vinyl clad windows

Extruded aluminum is a little more durable than roll-formed. Whereas vinyl clad windows are the least durable because vinyl is broken down
by the suns rays over time. However, vinyl’s low thermal conduction properties may provide a slightly higher energy efficiency rating over aluminum.

  • Energy Efficiency: Very Good
  • Price: High
  • Maintenance: Very Good
  • Durability: Good
  • Strength: Good
  • Color Selection: Good

Vinyl Windows

Once upon a time, vinyl windows were considered a less than ideal choice for window replacement. Design enhancements and improvements in vinyl formulation has improved the quality of the product. And now it is a nice alternative to wood.

Vinyl’s low thermal conduction properties make it nearly ideal for use in windows. Overall the thicker the vinyl, the stronger and more energy efficient the vinyl window will be. Remember: Not all vinyl windows are created equal. The type of vinyl used in the window has a big impact on the performance and lifespan of the product.

  • Energy Efficiency: Very Good
  • Price: Moderate
  • Maintenance: Very Good
  • Durability: Good
  • Strength: Average
  • Color Selection: Average

Cellular PVC Windows

Cellular PVC windows are fairly new to the window replacement market. Cellular PVC is a solid, extruded material that has the working characteristics of wood, and is used for interior trim, exterior trim, and paneling as well as windows and doors, blinds, and

Cellular PVC has very high tensile strength and resistance to movement caused by thermal expansion and contraction. Cellular PVC is medium white and can be painted with light acrylic paints. Because profiles can be welded like vinyl and milled like wood,
they can be produced to look like a wood window. Cellular PVC avoids many potential problems of wood, such as rot, split, water absorption, peeling paint, and termites. It can be left unfinished, or with a color-matched permanent finish.

  • Energy Efficiency: Very Good
  • Price: High
  • Maintenance: Very Good
  • Durability: Good
  • Strength: Good
  • Color Selection: Good

Aluminum Windows

Aluminum Windows were very popular when energy prices were not a concern. Today aluminum windows are used more in commercial buildings because of their structural strength, which allows very large glass sizes to be used.

Aluminum is a very good conductor of heat (1000 times more than wood and vinyl) and cold. However they can be designed with a much smaller profile than wood or vinyl. This can minimize heat frame loss and yield a larger glass vision area.

  • Energy Efficiency: Average
  • Price: Moderate
  • Maintenance: Very Good
  • Durability: Very Good
  • Strength: Very Good
  • Color Selection: Good


Fiberglass Windows are relatively new to the market and can provide a combination of benefits. Fiberglass is structural strong, expands and contracts very little with the temperature changes, and is a good insulator. Fiberglass frames are much stronger than vinyl and therefore can be made with a lower profile like aluminum but with better thermal efficiency.

Typically, fiberglass windows have been priced above vinyl and equal to the cost of high-end wood windows. As more new window products come on the market today, the issue of availability and price will determine which segment of the housing market will accept or demand fiberglass products.

  • Energy Efficiency: Very Good
  • Price: High
  • Maintenance: Good
  • Durability: Good
  • Strength: Very Good
  • Color Selection: Good

How to Tell if a Window is Energy Efficient

How to Tell if a Window is Energy Efficient

As you can see from this guide, there are a lot of window options in New Jersey with varying degrees of energy-efficiency. Due to the high cost of replacing windows, homeowners are often concerned with the energy efficiency rating of windows.

Check out our guide on how to create a more energy efficient home.

Finding a NJ window replacement company that can provide the best energy efficient windows is a must for those looking for a fast return on investment. But nowadays everyone says they have energy efficient windows. How do you really know how efficient a window is? What are some things that you should look for?

In this section, we’ll cover the primary energy efficient rating systems for windows in New Jersey.


Sample NJ NFRC Label

The National Fenestration Rating Council (NFRC) is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products.

Their goal is to provide fair, accurate, and reliable energy performance ratings so that consumer can compare different products and make informed buying decisions. In addition, their ratings are used to determine if products meet local building codes, establishing performance requirements, and to show benefits of new technology as it enters the marketplace.

By using the information contained on the NFRC label, consumers can reliably compare one replacement window with another. The NFRC label lists the manufacturer, describes the product, provides a source for additional information, and includes ratings for a variety of performance metrics including:

  • U-Factor measures how well a product prevents heat from escaping. U-Factor ratings generally fall between 0.20 and 1.20. The insulating value is indicated by the R-value which is the inverse of the U-value. The lower the U-value, the greater a window’s
    resistance to heat flow and the better its insulating value.
  • Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. SHGC is expressed as a number between 0 and 1. The lower a window’s solar heat gain coefficient, the less solar heat it transmits.
  • Visible Transmittance (VT) – measures how much light comes through a product. The visible transmittance is an optical property that VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted.
  • Air Leakage (AL) is indicated by a rating expressed as the equivalent cubic feet of air passing through a square foot of window area (cfm/sq ft). Heat loss and gain occur by infiltration through cracks in the window assembly. The lower the AL, the less air will pass through cracks in the window assembly
  • Condensation Resistance (CR) measures the ability of a product to resist the formation of condensation on the interior surface of that product. The higher the CR rating, the better that product is at resisting condensation formation.


ENERGY STAR is a program run by the U.S. Environmental Protection Agency and U.S. Department of Energy that promotes energy efficiency. The program provides information on the energy consumption of products and devices using different standardized methods.

ENERGY STAR qualified windows:

  • Are manufactured by an ENERGY STAR partner,
  • Are independently tested and certified by the National Fenestration Rating Council (NFRC), and
  • Have NFRC ratings that meet strict energy efficiency guidelines set by the U.S. Department of Energy (DOE).

Though ENERGY STAR does not require any specific technologies, certain product features are common in many certified products. Performance criteria for windows are based on the below climate zones and ratings certified by the National Fenestration Rating Council (NFRC).

Energy Star Climate Zones

Depending on where you are located in New Jersey, your windows should meet the performance criteria of either Northern or North-Central climate zones.

How to Choose a NJ Window Replacement Company

How to Choose a NJ Window Replacement Company

There are many window replacement companies in New Jersey and it can be overwhelming when trying to choose one. As a general rule of thumb, we recommend getting at least 3 estimates prior to making a decision.

With window replacement being a longtime investment, getting the right crew is extremely important. Here are some things to keep in mind when choosing your provider.

Lifetime Warranty

A lifetime warranty guarantees that the product you received from a business won’t fail,  and if it does, the service provider will replace and repair their initial work. A lifetime warranty from a window replacement company shows confidence in their work, and the warranty can also be transferred to subsequent owners of your home should you choose to sell it.

Full Transparency

Try to find a business that will discuss every detail of the window replacement process without sugarcoating anything. This not only shows their dedication but also their trustworthiness as service providers.

It’s a good sign if a contractor communicates effectively, or if they are willing to clarify terms that you don’t know. Follow-up and professionalism is something to pay attention to during the vetting process.

Reviews and Ratings

Go online and check a provider’s Better Business Bureau rating. These ratings show how well the business interacts with its customers. BBB often tracks how long a business has been operational, their transparency with customers, and even their history of complaints and how they were dealt with.

BBB has a comprehensive rating system designed to inform users with a full understanding of how well a window service provider serves their customers. Beyond the BBB, check out your potential window replacement company’s website, Facebook page, Google reviews, and any other third-party ratings. The more reviews and higher the ratings, the more you can rest assured that you will get a quality job.
