Rough Opening is the structurally-framed opening in the wall that will receive the window. For New Construction applications the actual unit will measure 1/2 inch less in width and height. For Replacement applications, the actual unit will measure 1/4 inch less in width and height.

Make size is the tip to tip measurement of the window frame (the nail fin is not part of the frame).

The glazing bead is located on the outside of the house for all products except for non-operable windows.

If your window has become cloudy or foggy it could be a result of condensation, or indicate that there is moisture between the glass panes, which means that you have a seal failure. A Seal Failure is when the insulated glass unit’s (glass part of the window) seal is broken, and moisture is allowed into the sealed unit. The accumulation of moisture within the unit can appear as condensation, or fog, in between your two panes of glass.

Viwinco Warranty Policy for Seal Failures

Photographic evidence is required. 

No, installing blinds into the jamb of the window will void the Viwinco warranty.

How To Replace an Extruded Full Screen in an S-Series Double-Hung Window

Follow the video below to help you remove your full screen.

Design Pressure (DP)
According to the American Architectural Manufacturers Association (AAMA), DP is a rating that identifies the load induced by wind or other dynamic pressures. The higher a DP rating, the more resistant it is to the effects of wind and other pressures.

Performance Grade (PG)
A numeric designation that defines the performance of a product in accordance with AAMA standards. PG is determined upon successful completion and verification of all applicable tests (air, water, structure).

Yes, to be a certified hurricane window, the window must pass an impact test. The test window is impacted by a “missile” (Viwinco uses a 9-lb. 2×4) and then subjected to 4,500 positive and 4,500 negative static pressure differentials. As part of the certification test, wind speeds 1.5 times the associated DP are cycled to ensure the window will meet greater wind loads.

Nothing is wrong with your windows. The presence of moisture on the outside of your windows indicates that a specific set of atmospheric conditions exists and that the insulating glass is indeed performing as it was designed to. In this case, that insulation capability is what slows the flow of building heat through the glass and prevents warming of the exterior above the dew point.

Though there’s little to nothing you can do to prevent exterior condensation, you can try keeping draperies open to allow as much heat transfer through the glass as possible. Shrubs near windows can increase the humidity in that area and may need to be moved. 

Condensation occurs when warm humid air meets a cool surface (glass window pane) causing it to condense and form water droplets. this is known as condensation. If you are experiencing condensation on the interior of your windows, it is likely due to a humidity buildup within the home. There are many sources of household humidity. The humidity that leads to condensation results from everyday life: taking showers, boiling water, humidifiers, water pans on radiators or wood stoves, kerosene heaters, drying laundry, and house plants also contribute to household humidity.

The construction of your home – the kind and amount of ventilation, the presence or absence of a basement – even the soil type and drainage patterns of the land on which it is built can add humidity as well. In many cases, you can reduce humidity simply by being aware of the sources and reducing your daily use – for example, taking shorter showers, or reducing humidifier usage. 

Here are more ideas for reducing humidity in your home:

If your home still has excessive humidity issues after you’ve tried the above steps, you may have a more serious problem. Talk to a professional such as your architect or heating contractor for assistance. 

Condensation is caused by household humidity. That fog or moisture you see occurs when warm humid air comes in contact with a cool surface. This is more common during winter months when your doors and windows are kept closed. A thin film of dew or frost on your windows is normal and will not damage them. However, if you see excessive condensation such as beads of water flowing down your windows or walls – that’s a sign of too much household humidity, which may need to be reduced.

For assistance with locating your warranty label, visit our Label Diagrams page.

The warranty label is very important, and without it, it is more difficult to find out details pertaining to your order. If your warranty label is missing however, here are some workarounds:

The warranty label on all fixed units is located on the interior side of the house, on the bottom sill. See our Label Diagram page for more information on the label location. You will then need to remove the glazing bead.

CertainTeed Claims:

Viwinco and CertainTeed are no longer affiliated. In 2007 CertainTeed sold their window program to Metal Industries at which time we decided to develop our own, new product line. Because of this, Viwinco does not have access to the parts required to service a CertainTeed window.

CertainTeed is the holder of your warranty and will honor any claims. You may process your claim through them directly. Listed below is their number to start the claim process.
