Replacement glass is a big part of what we do here at Pleasanton Glass.  Our courteous, professional technicians are fully trained to repair or replace any flat glass project in your home. Often we can repair cracked or chipped glass in single panes, instead of replacing the entire window or door.  If you have a double pane window that is cracked or fogged up we can also change out just the glass unit without replacing the window or door.  

  

REPLACEMENT DOUBLE PANE:

 

What is an Insualted Unit?
Insulating Glass (IG) units are hermetically sealed combinations of two or more lites of glass separated by a dry airspace. IG units improve thermal performance, significantly reducing heating and air conditioning costs. IG units also reduce interior condensation in cold climates.

Low-E (Hard Coat): Low-emissivity is a thin, metal, transparent coating applied to the pane of glass to reduce heat transfer through the window. This coating reflects solar heat outside in the summer and reflects radiant (furnace) heat inside in the winter. In addition, it blocks about 30-45% of UV rays protecting furniture, wood and artwork. On a cold day, low-e will be 40 degrees warmer than a single-pane glazing and 10 degrees warmer than a double-pane glazing. (R-Value of 2.85 to 3.8, U-Value 0.35 to 0.30)

 

 

Low-E2 (Soft Coat):  Low-E2 windows are an industry term to reflect the application of two coats of metal onto a window. This generation of windows used a technique called sputtering to help apply the metal solution. With the honing of this technique, silver flakes were introduced into the process to provide an even greater reflective surface for the windows to work with.

This made the dual-paned, inert gas filled windows an excellent vehicle for Low-E2 windows. The only problem with all double pane windows is the inherent gas leakage one experiences and any weaknesses that might have existed in the spacers. Double pane units generally last 10 years.

 

Low-E3: Low-E3 windows are another industry term that simply reflects the application of three coats of metal onto a window. This style of window tends to be a great all climate window because it offers great performance in colder weather (U-Factor) and enhanced performance in summer (SHGC). The third coating layer provides great benefit for keeping unwanted heat out of a building but one can only see so much gain from applications for insulating qualities.

 

 

Where should I use double pane units?
A wide range of applications include:

 

Fixed and Operable windows

Storefronts and Curtain Walls

Sloped/Overhead Glazing

Non-vision (Spandrel) Locations

 

Insulating glass units are fabricated according to project specifications. IG units can be constructed using a large variety of glass products to achieve desired aesthetics, meet design criteria, safety codes and/or to improve solar control and thermal performance. Glass options include clear, low iron, Low-E's, standard or high performance (spectrally selective) tints, reflective, silk-screened, spandrels, laminated, decorative and wired glass. The glass lites of an IG unit can be annealed, heat-strengthened, tempered or laminated.

 

SAFETY GLASS:

Safety glazing is required by the International Residential Code in a number of locations and is intended to reduce the potential for injury in the event of accidental contact with the glazing.

The two most common types of safety glazing are tempered and laminated. Each pane of safety glazing is required to be permanently labeled. The label typically consists of an etching in the corner of the window indicating if the glass is tempered or laminated.

 


What is Heat-Treated Glass?

Heat-treated glass is glass that has been processed through a tempering oven to increase its strength to resist impact, mechanical loads and thermal stress breakage. There are two distinct heat-treated glass products, heat-strengthened and fully tempered. 

What is Laminated Glass?

Laminated Glass is a multifunctional glazing material that can be used in a variety of applications. It is manufactured by permanently bonding two or more lites of glass with layers of polyvinyl butyral (PVB) interlayer, under heat and pressure, to create a single construction.


 
Safety glazing is required in the following locations:

** There are certain situations that require safety glazing. Below is the “Minimum” standards set by the “International Residential Building Code”. If your state or local codes require more strict codes remember in any building code situation, the MOST STRINGENT CODE APPLIES.

 

 

Safety Glazing In Windows


Glazing in an individual fixed or operable panel that meets all of the following conditions:


When it comes to safety, these Codes are taken very seriously, and are strictly enforced by any law, punishable by heavy fines or imprisonment or both. Contradictory to any rumors you may hear that these codes do not apply to a “Remodeling” or “Existing” situation please be assured they do apply in “ANY” situation.

** There are a number of exceptions to the rules listed above because of the design and variety of doors, glazing products, and locations. If you have questions regarding a specific location for safety glazing, contact your local Inspections Division
