At The Cracked Glass, we sell finished stained glass pieces and gifts. We specialize in custom design and installation. We also teach classes Tuesday through Saturday, and sell the glass, supplies, and tools needed to create your own glass designs. We offer repair and restoration services as well. Stop by our location in Dyer, Indiana, today! Our hours are Tue 10-5, Wed 10-1, Thu 10-8, Fri 10-1, & Sat 10-2.
We repair and replace glass windows of all kinds, from single- to double- to triple-pane, encompassing all frame materials from wood to aluminum to vinyl. And why just repair or replace when you can upgrade? We offer egress windows, noise reduction products and more energy-efficient options to help you save money on your energy bills.
Stress cracks more often occur in large windows that are beneath overhangs or are recessed behind a protruding outward room. The shadow lines created by the overhang or wall set up a quickly changing stress factor from the glass that is in the sunny, hot area that contrasts with the glass in the cool, shaded area.
If the wind blows down a large shade tree in your yard or a new house goes up next door, it could change the amount of shade on your window and create conditions for thermal stress cracks. Seasonal factors, like dramatic overnight temperature changes, are a common cause of stress cracks as well.
The short answer is: not really. Stress cracks are a naturally occurring result of expanding and contracting glass due to temperature changes. However, installing thicker glass and choosing glass features based on your climate and sun exposure needs may help decrease your risk.
If you have Pella Windows in your home and discover a stress crack, connect with your local Pella representative for assistance in replacement of the glass and/or the window as needed. Or call the Pella customer service team at 1-800-374-4758 or visit -to-buy/default.aspx to find a Pella representative near you.
Driving around with a cracked windshield is never a good idea be it for a long, or even short, period of time. When a crack happens it is best to start seeking out a reputable auto glass company sooner rather than later. You want to ensure the safety of you and those riding in your vehicle, and the windshield is an integral part of that safety system.
Yes- cracks can spread very quickly or very slowly and it depends on a great number of factors. Because of these numerous factors (temperatures, road conditions, etc.) it is impossible to say how long it will be before it gets worse. Our recommendation will always be to have a damaged windshield fixed as soon as possible because it is a safety concern. Many of our affiliate shops provide mobile service and can do the replacement at your home or work, which might help you get it done before the weekend. Either way, get in touch with a shop as soon as possible as they might need to order the glass.
Thank you for your INformation.. I called Autoglass and they told me it was safe to drive around with a crack in my windscreen on the drivers side until it can be repaired in a week! They said it was perfectly safe. I wonder if they have read information?,.

While you might not be a window expert, you may be surprised that you can fix a cracked window on your own. With the proper knowledge and materials, most homeowners can do the job themselves and avoid getting a full window repair.
There are two routes you can take to fix a cracked window: a temporary solution that takes care of the immediate problem or a long-term fix that is more intensive but provides a better result. We outline both options below.
If you only need a temporary fix, you can fix cracked glass at home by securing the glass with heavy-duty tape, glass adhesive, clear nail polish, super glue, or plastic bracing. For a longer-term solution and a cleaner finish, an epoxy mixture is recommended.

The crack patterns in broken glass and their fracture surface details describe the origination and energy intensity that caused breakage. This article discusses basic fracture technology of flat glass in architectural and structural glass assemblies, illustrating characteristic fracture surfaces and crack patterns. The objective is to provide information to engineers investigating glass breakage and tips for specifiers to avoid glass breakage problems.
Crack patterns provide significant clues to describe glass breakage when coupled with information about the Initial Fracture Surface. In AN and chemically-tempered glass, cracks form as single or branching lines. In HS glass, cracks form as multiple single and joining branching lines. In FT glass, cracks form across all surfaces, creating a multitude of small fragments.
In all flat glass, low-stress cracks, due to mechanical stress (e.g., flexural), typically occur oriented non-perpendicular to glass edges and often non-perpendicular to glass surfaces. High-stress mechanical cracks have similar orientations with branching cracks that break away from the initial crack within two inches of the initial fracture surface. On the other hand, low-stress thermal cracks are typically oriented perpendicular to glass edges and surfaces; high thermal stress cracks have a similar orientation with branching cracks that branch from the initial crack within two inches of the initial fracture surface (Figure 4).
In mechanical and impact cracks, AN low-stress edge cracks form as meandering single/branching lines. High-stress edge and surface cracks form as many radiating lines with circumferential rings. Crack patterns in AN, HS, and FT flat architectural glass (Figure 5) are combinations and permutations of these typical configurations.
This project includes a multi-layered structural laminated glass cantilever tread staircase in a private residence (Figure 6). The tread specification considered conservative static and dynamic stair loads, plus post-breakage capacity for safety, using AN glass laminated with a stiff structural interlayer material. Installation details included set-screw level adjustment with a maximum setting torque specification into padded brackets, with each tread independently installed and test-loaded. One tread top glass lite cracked in a single line across the lite at an applied load significantly lower than as-designed. Recovery of the failed tread allowed investigators to measure the fracture mirror and to determine that the glass fractured at flexural stress over 7,000 psi, whereas the design allowed for no more than 1,500 psi.
Further review determined that the supplied glass treads incorporated a flexible non-structural lamination interlayer material in place of the specified stiffer structural interlayer, resulting in glass non-composite performance and breakage at lower loading than as-designed. Replacing and load-testing all treads with glass laminated with the specified structural interlayer provided a resolution to the breakage problem. In this breakage example, initial glass fracture was a high strain energy event dissipating quickly due to excess loading of an improperly supplied laminated glass assembly.
The story of glass breakage is documented precisely in crack patterns and their fracture surface characteristics. As useful as these indications are for breakage investigators, designers and specifiers are more interested in avoiding breakage altogether. Here are five tips to assist in avoiding glass breakage in design:
The root cause of stress cracks is extreme temperature fluctuations. When there is a huge temperature difference between the inside and outside, stress cracks appear. These types of cracks usually start appearing from one edge of the window. In the beginning, stress cracks are very small and almost unnoticeable. However, they grow and spread all over the glass if not taken care of.
Pressure cracks are less common. They typically appear out of nowhere. The reason behind the emergence of pressure cracks is the change in the pressure system caused by the weather. The wrong placement of windows can also be a cause of pressure cracks. Pressure cracks appear as curves and spread across the windows.
It is one of the most common reasons behind cracked glass in windows. Most people experience cracked window glass due to hard impacts. The impacts can be of any type. A rock projected in the air, an off-target ball-hit, or the dirt and debris in the storm can cause this type of cracks in the window glass. These cracks have a center and spread across the window glass in the form of a starburst. The impact cracks can be small or huge based on the pressure of the impact.
Seeing a cracked window glass in your home is super annoying. You might get tempted to start the glass crack repair on your own. This way you can save your window glass from breaking any further. However, glass repair is not that simple. Some questions may pop up in your mind. 2ff7e9595c
