Why do vinyl windows crack?

When this happens, it places pressure along the edges of the glass. In addition, the space between the window panes is filled with pressurized gas to prevent the transfer of heat. When the frame contracts, it also compresses that gas, which presses outward on the window panes. Homeowners may come home to find that there are large cracks in the glass, typically starting in the corners and spreading up toward the center of the window pane. This is caused by the sudden application of pressure from the vinyl contracting. While some companies do offer warranties against this type of damage, once the window is opened for repair, the whole sash could be negatively affected.

How to keep condensation from building up between windows?

In order to keep moisture and condensation from building up between two-pane windows, a spacer is installed full of a drying agent. The drying agent absorbs moisture out of the air space and holds it in. Unfortunately, once the drying agent becomes fully saturated, it cannot absorb and more moisture. When this happens, the agent begins to slowly slump down toward the bottom of the window where it becomes visible, and over time moisture begins to creep outwards from the area where it gathers at the bottom of the window. Once it gets inside, it is impossible to get the moisture out.

How to tell if a glass seal is broken?

The “new” air circulating between the glass carries moisture that condenses between the panes. An insulated glass unit with a broken seal can be identified by visual moisture between the glass, or a milky white appearance to the glass. The fix is replacement of the insulated glass unit. Manufacturers Warranties for seal failure vary, but have generally improved with the introduction of more reliable spacer and edge systems for insulated glass. What was once mostly an industry-wide 3-5 year standard for seal failure, is now lifetime with some manufacturers.

Do windows have weather stripping?

Many older window designs have no weather stripping as we know it today. The air-seal was achieved through wood against wood contact or wood against metal contact. Neither would be acceptable by current standards. Today, all windows are tested and receive an air infiltration rating (CFM rate). No operating window has achieved a zero CFM rating. For a homeowner in a climate that experiences subzero temperatures and strong wind, an expectation that NO cold air be detected coming through a window is unrealistic. Contemporary designs use multiple weather strips at each contact point. Double weather strip systems are commonplace today, although some windows still rely on a single seal. The tightest windows today for air infiltration incorporate triple weather strip designs that put three pieces of weatherstripping at each point of contact. Homeowners in colder climates should strongly consider triple weather strip windows and the lowest CFM ratings.

Why do windows fail?

This is problematic because when the outside air sneaks in between the panes, it brings moisture with it. This moisture gets caught inside the window panes, which is identified by visibly seeing the accumulation of moisture or white haze that gets trapped in between the panes. When this happens, replacement of the insulated glass unit is necessary.

What happens if a window frame breaks?

A broken window frame is a serious issue. The window frame is critical to the success of sealing the window properly. If the window is broken, or if it has rot, it definitely needs to be replaced. Some very old homes have wooden window frames that have been able to withstand 100 years of life and weather before needing replacement. Then again, there are also window frames less than 20 years old needing replacement, which can be a sign of serious manufacture and/or material deficiencies. Either way, if you have a broken window frame, replace it.

Why do my windows fail?

What is the purpose of silica desiccant in windows?

Built into every thermal pane window frame is silica desiccant to absorb the small amounts of moisture inevitably drawn into the window . The desiccant, however, has a limited capacity and lifespan. In a standard box spacer the desiccant looks like the photo below. In an Intercept Spacer, the desiccant is mixed into the sealant that forms the seal of the window.

How long do double pane windows last?

Every double pane window eventually fails. There is no such thing as a fail-proof thermal pane window. Wood framed windows tend to last 20 to 24 years (if well maintained). Newer, high-end wood/aluminum clad windows last about this long too. Traditional aluminum frame windows typically last 17 to 20 years. Vinyl framed windows may make it 15 years if they have standard box spacers. However most newer vinyl framed windows have a low-quality Intercept Spacer and these windows begin failing in 5 to 8 years.

Why do wood frames fail?

The biggest cause of early failure in wood framed windows is lack of maintenance. Every two years the exterior seam where the glass meets the wood needs to be caulked and the frames painted. Otherwise, rain hits the glass and runs down between the wood and the glass, pools at the bottom of the IGU (Integrated Glass Unit) and rots both the seal of the IGU and the wood frame of the window from the inside out. Once the seal has failed haze, fog and eventually a mineral deposit will develop in your window.

What happens when sunshine hits a double pane window?

The warping can also do some damage to the seal. Not only does this combat your energy efficiency, it allows moisture to wiggle it’s way through, getting trapped between panes. This can cloud your view and possibly lead to some mold.

Do you need more vinyl for glass?
