Replacing the fogged glass instead of the windows saves money and helps maintain your homes' value.

If your windows or patio doors have become cloudy or contain moisture between the glass call Dymond Glass. An experienced technicition will inspect your windows, measure and quote a price on the first visit, free of charge. Replacement thermopanes will be manufactured to the exact size needed for your windows.

Installation by our experience staff will be completed on the next visit. Dymond Glass replacement thermopanes carry a 10 year written guarantee against seal failure. Thermopanes can be manufactured with the latest glass technologies, including:

♦ Argon Gas Filled
♦ Tints
♦ Tempered Glass
♦ Laminated Glass
♦ Obscure Glass



Why Insulated Window Glass Fogs


Maybe it's happened to you. You wake up one morning and notice one of your double-pane windows or patio doors is a little cloudy. You wipe the inside pane with the sleeve of your bathrobe and the cloudiness remains. You wipe the outside pane and get the same results. Then you have a revelation: Eureka! The cloudiness is between the two panes of glass. Some days (and especially at night) the cloudiness disappears, but then it reappears and over time the cloudy area becomes larger, thicker and more obtrusive. Welcome to the Insulating Glass Failure Club.


How insulating glass works


Insulating glass, often referred to as "IG," "double-pane" or "Thermopane" glass, was developed to create a more energy-efficient window. Insulating glass is created by bonding two panes of glass together along their perimeter while maintaining a (usually) 1/2- to 3/4-in. space between them. Most high-quality double-pane windows manufactured today have two perimeter seals, an inner seal that resists water, aging and corrosion, and an outer seal that provides rigidity and strength. If one seal fails, the other cančat least for a whileč pick up the slack. Some windows may have just a single seal. A hollow, usually aluminum, tube or spacer is the other element in seals. Its job is to keep the panes rigidly spaced. This tube usually holds small beads of a moisture-adsorbing (similar toabsorbing) desiccant to keep windows from fogging up if a small amount of moisture penetrates the seal or is trapped between panes during manufacture. But once the desiccant is saturated and moist air starts entering through a bad or broken seal, it's a downhill slide. It's just a matter of time before your window starts to fog.

Insulating glass in windows and doors has to put up with a lot of abuse. The seals have to withstand slamming and banging. They have to be flexible enough to allow the panes to contract in cold weather and expand in hot. The seals can't stiffen and become brittle in the cold or soften and ooze when it's warm. They have to stand up to wind, hail, rain, damaging ultraviolet rays, old age, atmospheric pressure changes, errant Frisbee discs and suicidal birds. Still, with all these challenges, double-pane windows are remarkably reliable. Studies by the Sealed Insulating Glass Manufacturers Association show that high-quality units manufactured by their members, and properly installed, have a 1 percent failure rate after 10 years and a 3 percent rate after 15 years.


The leading causes of failure are:


1) Seals breaking down from exposure to water. Windows without the proper safeguards to keep water from puddling around the perimeter seals will fail sooner.

2) Excess heat. Talk to companies that replace insulating glass and they'll tell you most of their work takes place on windows with direct sun exposure. Heat causes the panes to expand and contract, and it softens and weakens the seals until they develop a crack in their armor and allow moist air in.

3) Old age. Even the most elastic, flexible seal can't last forever. Eventually a seal will allow moisture to enter the window.

Impact will rarely break the seal of a healthy window, but it can be the last straw for one already weakened from one of the above situations.

When windows fog and fail, the only viable option is replacement. It's extremely difficult to separate the old panes, clean them up and reseal them again: The glass becomes "etched" from minerals in the moist air, the old seals are difficult to remove in order to get a tight new seal and a repair is just not cost effective. And the heck of it is, there's not much you can do to prevent window failure.

Energy Efficient Thermopane Glass


Prior to the 1970's most windows contained only single pane glass. During the energy crisis, the Federal Government funded research for the development of more energy efficient products, and many advances were made in the production of glass. Several options are now available, so that you may choose the level of comfort and energy efficiency that you desire.
Dymond Glass
Dual pane insulated glass with Intercept Warm-Edge spacer†is approximately twice as effective as a single pane of glass in reducing heat transfer. It is created by sealing two single panes of glass to a spacer, creating an insulating chamber that traps air, so that heat does not pass through the window. This means that your house will stay warmer in the winter, and cooler in summer, so you save money on your energy bills and are comfortable all year long.

LoE Glass†is coated with two microscopically thin metallic layers, which reflect radiant heat while permitting the passage of visible light. In hot climates, LoE glass reflects unwanted solar heat, helping to keep your home cooler and reduce cooling costs. LoE glass helps keep your home warmer in the winter as well by reflecting radiant heat back into your home. This not only keeps you more comfortable, but also helps to reduce heating expenses. LoE glass blocks 96% of ultraviolet rays, which will protect your drapes, furnishings and carpets from fading caused by the sun.

Laminate glass, created by bonding two pieces of glass together with an inner layer of rugged, transparent plastic, is widely used in auto windshields. Although it is transparent, this tough film is 99.9% effective in blocking ultraviolet rays, prolonging the life of your furnishings. Laminate glass provides superior noise reduction, reducing sound transmission by as much as 50% when compared to ordinary glass. If broken, the glass will adhere to the plastic inner layer, helping to prevent injury caused by shards of glass, therefore making it safer than other types of glass.

Tinted glass†works to reduce heat transfer by filtering out ultraviolet light and infrared radiation. Because tinting can also reduce the amount of light transmitted, it is reserved primarily for warm climates, or for windows with a southern or western exposure. Tinted glass may also be combined with LoE2 or LoE3 for maximum energy efficiency. Dymond Glass offers Bronze, Green and Gray tinted glass options.

Tempered glass, sometimes referred to as safety glass, is 4 to 5 times stronger than ordinary annealed window glass. This provides an extra measure of protection for your family. When tempered glass breaks, it breaks into small pieces that are not sharp or jagged. In the event of an accident, someone is much less likely to be hurt.

Obscure glass†offers privacy where window coverings are not desired, in areas such as bathrooms or for use in sidelights. Obscure glass provides a translucent, rather than transparent appearance.
