Fogged glass in double pane windows typically results from seal failure, which allows moisture to enter between the glass panes. This condition also reduces the window's insulating performance. A reliable local window contractor such as Winnebago Window & Door LLC can evaluate the problem and offer replacement solutions.

Low-E coating is a clear coating applied to window glass that reflects ultraviolet light and enhances energy efficiency.

U value measures the rate of non-solar heat transfer through a material or assembly. Testing typically occurs under simulated conditions of 0 degrees exterior temperature and 70 degrees interior temperature with 15mph wind. Lower U-values indicate greater resistance to heat flow and superior insulating performance. The U-value is calculated as the inverse of the R-factor.

The R factor indicates the insulated glass unit's resistance to heat transfer. Windows with higher R factors provide greater heat flow resistance and superior insulating performance compared to windows with lower R factors.

Triple pane windows deliver superior insulation, maintaining warmer interior temperatures during winter and cooler temperatures in summer. The extra glass pane typically provides a 0.07% improvement in U factor performance. Reference our U factor information for additional details.

Numerous companies impose excessive charges for triple pane windows, frequently adding substantial markups despite identical installation procedures as double pane units. While exact pricing varies by window size, triple pane windows generally cost $50 to $150 more per unit. Winnebago Window & Door LLC incorporates only the manufacturer's additional cost in our triple pane quotes to prevent overcharging.

We established the brand in 2025, expanding the service territory of Ripon Window & Door to better serve customers in the Oshkosh, Appleton and Fond du Lac regions. Our goal is to deliver three decades of exceptional service, products and pricing to additional homeowners.

This concern has merit. Builder grade vinyl windows are inexpensive, thin and susceptible to problems. We can demonstrate our durability standards during home consultations, as our windows are typically 40% deeper than builder grade products (3¼" deep, 1"+ sashes), feature thicker vinyl (0.88 mm continuous extrusion), include 95%+ foam filling and additional sash reinforcement. Our products feature windows certified for crime prevention. We frequently replace windows in homes constructed just five years ago due to poor product quality and installation. Our lifetime warranty on vinyl windows demonstrates that our products withstand Wisconsin's harshest winter conditions.
