CA 100 AD: The first fixed glass window was
likely produced in the Egyptian city of Alexandria under Roman occupation.
532: Stained glass was introduced into cathedrals
and mosques by using marble frames to hold the glass, and then framed in wood.
1100’s: Stained-glass became more refined by
using lead to separate the pieces of glass.
1400’s: Fixed windows began to be replaced by
hinged glazed sashes, or casement windows. Rec-tangular openings became standard in buildings.
1600’s: Glass windows became common in all
homes as glass become more available and afford-able. Glassblowing techniques limited the size of the panes to small leaded lites.
The vertical gliding window and the double-hung window were developed in England
1700’s: A new technique for making window
glass allowed larger panes to be produced. 1800’s: The invention of more accurate metal
casting birthed the iron window.
Processes were developed to allow the mass-production of even larger panes of glass, allowing windows without lites.
1930’s: The birth of the aluminum window.
Double pane glass invented to increase energy efficiency.
1950’s: The birth of the vinyl window
1983: Cardinal glass introduces LoĒ™ coatings
to produce triple-pane performance in dual-pane windows
1992: First Ultrex Fiberglass window released
Welcome To The Evolution Of Windows We wrote the Evolution of Windows, because shopping for windows can be a daunting task. This
guide will help you wade through the various window materials available on the market, and choose
what’s right for you.
I’m a picky man, (my staff calls me a finicky craftsman) and I wouldn’t be able to sleep at night if I
didn’t tell you what my 25 years in the window industry has taught me: not all windows are created
equally. I’ll be upfront and admit that there’s only one window that we’d recommend, because it per-
forms the best. Don’t believe me: See for yourself as you explore The Evolution Of Windows.
Sincerely,
John Schwager Owner of Accurate Window & Door
The History of Windows Windows have changed a lot over time. Since the beginning of houses, window openings have been filled with small grilles made of stone, wood, iron, or glass. Sometimes other translucent materials such as paper, mica, or paper were also used to cover the opening. As glass advanced, modern windows were born, and various window materials were used to meet the demands of the market.
Wood
Pros
The standard for beauty & traditional craftsmanship
Can be painted & stained
Cladding on wood slows deterioration
Cons
Usually the most expensive option
Very high maintenance
Labor-intensive finishing
Can rot, mold, or swell
Easily damaged
Difficult to change the exterior color of wood cladding
Dark colors fade quickly
Cladding can hide deterioration until it’s too late
Modern wood is less weather resistant
New Lumber Vs. Old
Wood became the standard frame material as glassmaking devel-oped and the modern window was born. Today, wood windows re-mind us of the days when homes were built by highly skilled crafts-men who took pride in their work. Beautiful profiles, narrow frames, and warm tones give a traditional, old-fashioned look to any home.
New Lumber Shortens the Lifespan of a Wood Window
The unavailability of old lumber guarantees that modern wood windows aren’t the same as they were 100 years ago. Every year, a tree surrounds Itself with rings of weather-resistant sap to help fight the elements. New lumber has significantly less rings, and can’t stand up to the weather as well as your great-grandfathers wood windows.
Moisture And Maintenance Are Guaranteed
The weather and wood are mortal enemies, guaranteeing a lot of maintenance to keep the window from rotting. The battle begins when you first install the window. If you don’t paint or stain any one of the many wood surfaces, the wood will begin the journey to deterioration. There’s a lot of scrapping, sanding, and painting needed to keep a wood window looking beautiful throughout the years . When you think about having to do that with ALL of the windows in your home, it can be an overwhelming and expensive project. In fact, it’s so overwhelm-ing that few homeowners dedicate the time or resources needed to keep their wood windows looking great.
Aluminum-clad helps, but it’s not perfect
After seeing the weaknesses of a wood window, manufacturers started covering wood windows with aluminum to help protect the exterior from the elements. Unfortunately, moisture still finds ways to get in as the wood moves with the metal, and opens up seams. The high-temperatures of the metal absorbing the heat of the sun acceler-ates the deterioration process, but you can’t see it happening be-cause it’s hidden behind the aluminum. Before you know it, the win-dow is falling apart, and you’re taken by complete surprise. If you do get an aluminum clad window, ensure it’s extruded and not roll-form aluminum. Roll form is as thin as a coke can, is easily dinged up, and fades quickly.
The Grandfather Of Craftsmanship

Metal
Pros
Very strong, allows narrower frames and more daylight
Low maintenance
Easily painted
Inexpensive
Cons
Can pit, corrode, & rust
Conducts high rates of cold & heat, driving up the cost of utilities & making rooms uncomfortable,
Unattractive industrial look
Darker colors fade
High seal-failure rate
The first metal windows were made from wrought iron by highly-skilled medieval blacksmiths, and were most commonly used in ecclesiastical buildings and expensive homes. New metal casting techniques in the mid-18th century allowed the manufacturing of iron frames, creating an inexpensive alternative to wood. The natural strength of iron made them popular in lunatic asylums, workhouses, and schools. In 1856, Sir Henry Bessemer pioneered a new process for hot rolled steel, and steel replaced iron as the metal of choice. Steel windows became most popular after the First World War, as the country demanded homes fit for the heroes returning from battle. They were also commonly selected for skyscrapers and commercial buildings due to their low-cost, narrow sashes, and futuristic look. Aluminum windows have been around since the 1930s, and be-came more commonly used in the construction industry after World War II. By the 1970’s, they became the primary metal window, over-taking steel, and rivaling the dominate wood window industry; espe-cially in commercial and institutional construction.
Metal Creates Higher Energy Bills
The biggest pitfall of metal windows is the amount of heat and cold they transfer into the home. Metal is the least energy-efficient window material, and is guaranteed to create higher energy bills and uncom-fortable rooms. Exposure to the sun can also cause dark exterior col-ors to fade.
Seal-Failures Bring Foggy Glass
The amount of heat transferred also increases the rate of seal-failures. As the seal of a double pane glass unit heats up and cools down with the .aluminum, it starts to weaken, until it finally fails. Any argon gas used to insulate the window escapes, and the window becomes permanently foggy.

Vinyl
Pros
Cheapest up-front cost
Low maintenance
Energy Efficient
Cons
Lowest quality option
Short lifespan
Becomes pliable at 120-140 degrees
Major expansion & contraction
Big, bulky frames with less glass
Excessive weather-stripping
High seal-failure rate
Ugly welded corners
Can’t be painted
With the rise of heating and cooling costs in the 1970’s and 1980’s, manufactures started looking to vinyl windows as an alternative to metal’s poor energy performance and wood’s high maintenance. Vi-nyl windows became popular in Europe after World War II, but took longer to be embraced in the United States because consumers were weary of windows made from plastic (PVC). Vinyl’s popularity in the USA was fueled by low prices, and govern-ment rebates encouraging the purchase of energy efficient windows through the Energy Star program.
Less Strength Means Bigger Frames
Companies have manufactured wood, aluminum, and fiberglass ladders, but no one has made a plastic ladder because vinyl isn’t very strong and has way too much flex. You can see the lack of strength by looking at vinyl's big, bulky frames. Vinyl needs bigger frames to have enough strength, leaving less space for glass than other win-dows. If you do purchase a vinyl window, we recommend getting one with a bulky frame, because it’ll last longer.
Vinyl Deforms In The Sun
Vinyl frame extrusions are made by heating up PVC and pushing it through a mold that forms the frame. Because vinyl melts with heat, it can be recycled and turned into other products. Unfortunately, a vinyl window can also start to deform at 120 to 140 degrees. During a hot sunny day, the frame can easily reach 120 as the surfaces soak up the heat, and the glass magnifies the temperatures of the sun.
Expansion And Contraction Is an Issue
Out of all of the window materials, vinyl expands and contracts the most. In fact, a south-facing, six-foot window can move up to 3/8 of an inch a day. Manufactures plan for deformation, expansion, and contraction with very basic window designs that hide the shifts, big gaps in- between the sash and frame, and a lot of weather-stripping. risk for seal-failure as the ever-shifting vinyl puts pressure on the glass.

Fibrex
Pros
Strong frame
Low maintenance More resistant to heat than vinyl
Cons
High price-point
Experimental hybrid
Expansion & Contraction
Darker colors fade
Fibrex is an experimental composite released in 1992 by Andersen Windows. They combine 60% vinyl shavings and 40% wood flour to create a material that attempts to get the best out of both vinyl and wood.
Untested Waters
There isn’t a whole lot to say about Fibrex, simply because it’s a fairly new composite that hasn’t had a whole lot of time to prove how it performs. The manufacture knows this, and only warranties the non-glass components of their window for 10 years. Better But Not The Best
The mixture of vinyl and wood does help to overcome some of the disadvantages of each material, but when you look at the numbers on the next page, you’ll see, it still acts much like a vinyl window.

Fiberglass Fiberglas is manufactured by forming strong cables of glass and saturating it with resin. You’ll find fiberglass on boats, airplanes, fishing poles, and even the auto body of the Chevrolet Corvette. We recommend this material be-cause it’s strong, durable, and ready to hold up to anything the Pacific Northwest has to throw at it.
The Cons Of Fiberglass
Due to the high cost of manufacturing, fiberglass is one of the more expensive options, and lead times are usual-ly longer because windows are often custom ordered to size. Some fiberglass manufacturers also have an ugly bumpy, matted finish to the window.
Ultrex Fiberglass
Ultrex is a pultruded fiberglass designed by John Jambois, an innovator who wanted a material that would per-form exactly the way he wanted it to. He meticulously designed the best mix of roving and matting, and a patented resin to make the fiberglass as strong and durable as he possibly could. Marvin introduced Infinity Replacement Windows in 1992, creating a new line of fiberglass windows designed specifically for replacing old windows. There are several advantages to Infinity from Marvin windows that allow us to wholeheartedly rec-ommend them for your home.
Description
We recommend windows by Infinity from Marvin, because they are built by people who really care. Although it’d be
cheaper for Marvin to move their main factory and headquarters to a city closer to highways, they maintain committed
to the small town of Warroad, Minnesota. During the economic downturn in 2008, they were determined to avoid lay
offs at all costs, because their greatest concern is people, not profits.
Their strong commitment to people translates into one of the best windows out there. Instead of using cheap
hardware to cut costs, they selected some of the most expensive (but some of the best). That’s just one example of
why we love the Marvin family ethos. I think you’ll discover the same thing when you compare this window side-by-side to any other out there.
