vinyl replacement window

The history of Bonded begins after World War II with a small construction and insulation company.  Aware of energy conservation even then, blown-in mineral wool and fiberglass insulation became the primary direction the business was headed until 1989.  

When the first practical aluminum framed storm replacement windows arrived, these were added to complete the conservation properties of the homes and businesses in northern New Jersey.  2-track storm windows with side expanders  became obsolete in the mid 1950's with the advent of 3 track tilt style storm windows.  The 3 track tilt style aluminum storm window remains in great demand. Designs are largely unchanged since the mid-60's but extrusion, hardware and weatherstrip technology has greatly improved from the days when storm windows were king.

Among the first to sell an aluminum framed ratchet style replacement window with single glass, Bonded quickly joined in the rise of sideload and tilt style aluminum replacement windows and the first vinyl windows in 1972. Insulated glass for replacement windows was still in its infancy. Ongoing technology and designs brought poured polyurethane thermal break aluminum frames into widespread commercial use in the late 70's and early 80's..

     The early 80's saw great strides in vinyl technology, rapidly replacing aluminum as the material of choice for residential use. The 90's saw welded vinyl come in it's own as a better way to produce vinyl framed windows, but it wasn't until the millenium that welding technology, extrusion and polymer technologies caught up with each other, creating the new windows now available.  Insulated glass production and warranties improved with better technological breakthroughs in sealants, spacers and dessicant compounds.


     Bonded has been part of the growth in the window industry since 1944. Three generations have learned that performance through design is best, the cheapest isn't always the best way to go, service counts, innovation stands out and personal contact is so very important.

It is difficult to completely eliminate moisture on existing windows. Inefficient windows (e.g., single pane with aluminum frames) or high moisture with inadequate ventilation can result in condensation, frost, or pools of water on windows and sills. Moisture in the air condenses when it touches a cold surface. (The same effect causes a glass of ice tea to "sweat" on a hot humid day.) Continued excess moisture can lead to mold, mildew, and deterioration of your windows and sills.

Of course windows don’t manufacture water.  If you were out in the desert, you’d want a canteen, not a window.

            But people seem to believe that windows manufacture water.  They call up window contractors and say. “my windows are all wet, and it’s the fault of the windows.  I never had condensation before.”  Well, not quite.

            Water on windows is condensation and it can be a problem and it has a solution.  But it’s not a window problem and the solution doesn’t come from the window.

            What causes window condensation?  What can you, the homeowner, do about it?  More and more homeowners are concerned about growing condensation problems... and they are growing. There are several explanations for this last remark.  For the most part, the problems can be traced to “progress”.  For example, the “tight” construction of newer homes...increasing use of modern labor saving appliances...certain building materials...smaller homes...more gas furnaces...more showers.

            A little fog on the corners of your glass shouldn’t bother you.  And it probably doesn’t.  But “problem” condensation, fog or frost that covers whole windows, definitely bothers you.  And it should.  The visible effects are just the tip of the iceberg.   What is happening elsewhere in your home?  Take your attic.  Excess moisture may be freezing in the insulation where it will later melt and damage your plaster.  Or perhaps it’s forcing its way out through your siding, where it will form blisters under the exterior, or it may be promoting mildew in your home. 

   The culprit is too much water vapor.  Not the window, not the insulation, not the paint.  The only answer is to get rid of excess water vapor.  Water vapor, or humidity, is one of the invisible components of air.   This humidity tries to flow toward drier air, since this air has a lower vapor pressure.  In other words, the higher vapor pressure in moister air forces the moisture to areas which are drier.

            In cold weather, the air outside is generally drier than within a warm house.  What happens, then, is that the moisture is forced to the outdoors.  The most obvious indication of this is condensation on your windows:  the moisture comes in contact with the cold surface of the glass.  It therefore condenses to form either frost or water (depending on whether the temperature of the glass surface is below or above 32°. 

            The “tight” construction of modern homes traps the moisture in many ways.  Certain varnishes, tiles, plastics and acrylics—which are increasingly used in construction—do not allow moisture penetration.  Thus the moisture created by kitchens, laundries, bathing and human bodies (as well as cat, dog and other pet bodies) can’t flow easily to the outside.  Insulation and construction materials that are designed to keep cold air outside also keep moisture inside, further increasing the moisture level in your home.       

In simplest terms, condensation is simply moisture build-up on a material that is below the dew point temperature of the surrounding air. If the glass goes below that temp - you have condensation. If it doesn't then you don't
