A Window is Made Up of 3 Things 

1) Frame, made up of steel, aluminum, wood, vinyl or fiberglass

2) Components, such as hinges or cranks to open the window, or mechanics to allow the glass to slide

3) Glass, in single, dual, or triple pane. The dual pane glass unit alone can always be replaced, not repaired. A window is considered to be "repaired" when the glass is replaced. 

On a dual pane unit, if only one of the pieces of glass is cracked or fogged up, both pieces of glass must be replaced in order to maintain the integrity and benefits of the dual pane unit as a whole. When dual pane glass looks foggy, the seal for that unit has "failed".

One glass is cracked
in my dual pane window, 
can you just replace 
that piece of glass?
My dual pane glass is fogged up, 
can you clean it, then fix the seal?
Do you seal the two pieces of glass at my house 
or at your shop?
Dual pane glass units MUST be made in a multi million dollar (practically sterile!) facility. This ensures a better product! In theory, a local glass shop can purchase glass, metal spacers and butyl to put into a cocking gun in an ATTEMPT to manufacture their own dual pane insulated glass units, HOWEVER, the rate at which "home made" units fail (condensate) is FAR TOO HIGH and certainly would not meet our standards. 

My glass is broken, 
do I have to replace my 
whole window?
A dual pane, or "insulated" glass unit is made up of two pieces of glass, a spacer bar (made up of either aluminum or butyl), desiccant, and one, sometimes two, seals. 

First, two pieces of glass are cut to the desired size and thickness, and checked for any defects or flaws. It is very important that each piece of glass be cleaned in a dust free, air filtered environment. 

Next, the two pieces of glass are put together and sealed, if a smudge or fingerprint, or even a piece of lint or dust is caught in between the two pieces of glass, the unit must be thrown away and remade.

Aluminum spacers that will serve to separate the two pieces of glass are made, prepared and cut into four pieces for the two sides, a top and a bottom. Spacers are made to be hollow and then filled with “desiccant”- small round balls that look like bird seed. Desiccant will absorb moisture and prevent the panes from fogging up.

For unit assembly, one of the piece of glass is laid flat, then the four pieces of aluminum spacers that have been connected at all four corners, will be placed on top of the piece of glass, and the final piece of glass will be placed on top of the aluminum spacer bar. A very hot, rubber like material called "butyl" is pumped around the edge of the dual pane unit out of a machine to seal the dual pane unit.

Once the insulated dual pane unit has been sealed, and had a proper amount of time to cool, it is put into a room that is blocked from all light. Each dual pane unit is placed on a table with a black light shining up through the glass from underneath. This process allows the manufacture to see any flaws, smudges or fingerprints that have snuck by an earlier inspection. If an inperfection is found not to be within industry standards, the unit is thrown into recycling, and the entire process is started over.

Energy Efficient Windows

The estimated amount of heat or air conditioning lost through the windows in the average home is somewhere between 15 – 40%. New, energy efficient windows have double, if not triple pane windows with Low E glass, and possibly argon gas filled, and will increase the energy efficiency of your home. If you're tired of taping plastic over your windows every winter to stop heat loss, these window are for you. Low E, short for low-emittance, have microscopically thin, virtually invisible, coatings made of metal or metallic oxide layers. They are deposited on a windows glazing surface to reduce the U-factor by suppressing radiative heat flow. So, what does this REALLY mean?

Low E glass is a type of treated glass that that conducts visible light while controlling the passage of heat. Low E stands for low emissivity. This glass is an energy efficient way to control the heat being allowed in and out of a home or environment. Different types of Low E glass are available to meet the needs of varying climates. Heat transferred through glass is measured by the U-factor. This is the rate at which glass conducts non-solar heat flowing through it. The lower the U-factor rating, the more energy efficient the glass. Low-e glass allows visible light to pass through it but blocks heat-generating ultraviolet, requiring less artificial heating or cooling to keep a room at the desired temperature.

This glass works by reflecting heat back to its source. All objects and people give off varying forms of energy, affecting the temperature of a space. Long wave radiation energy is heat, and short wave radiation energy is visible light from the sun. The coating used to make Low E glass works to transmit short wave energy, allowing light in, while reflecting long wave energy to keep heat in the desired location.

Low E is now available in what is called – Low E squared, or Low E2. In simple terms, this means the sealed, dual pane unit is coated on both sides, interior and exterior. Low E Glass helps keep your home cooler in the summer, and helps to keep a good amount of the heat inside your home in the winter.

Windows for Comfort, Convenience, and Energy Savings

Tired of using a stick to hold your window open, or do you have a sliding window you have to wrestle open? Dread your heating bill in the winter and hate having to tape plastic over your single pane windows to keep your bill down? Perhaps, you simply don’t like the look of old rotting wood or cheap metal frame windows and want an updated look. 

Sometimes getting new windows is like replacing your old car with a newer model. Your old car leaks oil, guzzles gas, has a couple dents, faded paint, and the a/c works when it feels like it.  Your new car has remote start, power everything, looks greats, gets great gas mileage, has satellite radio, ice cold a/c, has lots of other cool new features, and what a pleasure it is to drive! Ok, new windows aren’t as much fun as driving a brand new car, but you get the idea.
When is it time to replace your
entire window unit, 
not JUST the
broken or foggy glass?

SINCE 1998
Windows work GREAT!
The Rock Glass and Mirror replaced the balances in my windows and now they work better than they ever did. The windows never did work right since our home was built. They fixed the problem that our builder couldn't fix. But now they work GREAT!!! Scheduling the repairs and completing the work went very smooth. I would recommend this company and will use them again for any window needs that I may have.

​Bruce O. of Flagstaff, AZ

Great job
They were here when they said they would be and did the work required. We were pleased.

Mario O. of Sedona, AZ

I was happy with the installation and the end result. Price was good. The only "bad" thing was how long it took to get the window so it was really cold when they put it in.

Len W. of Flagstaff, AZ

The service, price and quality was excellent. I would recommend Rock Glass & Mirror without any hesitation. 

Barbara G. of Flagstaff, AZ

Prompt & professional
When the top pane of our garden window was broken by a hail storm, The Rock Glass & Mirror was recommended to us by the building supply store where we had bought the window. We called, and they made two visits: one to measure the glass and a second one to install the new pane once it had been pre-fabricated. Both times, they arrived right at the beginning of the period we were told to expect them. It's nice not to have to wait around for hours! The measurement only took a minute, the installation not much longer. Now our window is good as new and we are very satisfied.

Randy K. of Flagstaff, AZ

A great experience from beginning to the end.
Excellent suggestions regarding the project and the installation was excellent. Would highly recommend.

John L. of Flagstaff, AZ

Office mirror
Technician was great. Very friendly, accommodating, and professional. Would give 5 stars except that it took 2 weeks for delivery. 

Dan O. of Flagstaff, AZ

No complaints
Other than I had no business card with address, etc. and I did not get an email confirmation so was beginning to feel like I had been pretty stupid and might have been scammed. Fortunately, that wasn't the case, but I had to google the company name before I knew it was legitimate. I respect their attempt to eliminate as much paper waste as possible, but is important to have contact information and immediate receipt for deposit paid. The company had done some work for others in the RV Park and a friend introduced the rep to me. He measured the windows, gave me an estimate, was polite, etc., took my deposit and said I'd receive an e-mail confirmation shortly. For some reason I never received it and realized I had no idea how to contact the company. I think it was a fluke situation of mistakes and hopefully just a mistake, but felt the feedback would be helpful. Other than that the service was good and professional installed.

Anita R.P. of Munds Park, AZ

Great folks
