Wisconsin experiences a continental climate with considerable seasonal variation, including periods of severe thunderstorms and hail during the warmer months, and significant winter storms that can produce high winds and heavy ice. These conditions require impact-resistant windows that are rigorously tested to standards like ASTM E1886/E1996, ensuring they can withstand projectile impacts and substantial wind pressures. Proper installation is critical, especially in urban settings like Milwaukee, to maintain the building's thermal envelope and prevent water intrusion.
When evaluating impact window manufacturers for your Wisconsin property, it is important to seek out providers who are knowledgeable about the state's building codes and specific permitting processes. The Wisconsin Uniform Dwelling Code (UDC) and Commercial Building Code establish performance requirements for windows, particularly concerning wind loads and impact resistance in designated areas. Manufacturers should be able to furnish certified products that meet these mandates, supported by comprehensive documentation. Their ability to provide solutions tailored to the unique architectural styles found across Wisconsin is also a key consideration.
Common questions
What is an impact window?
An impact window is a type of window designed with laminated glass and reinforced frames to withstand extreme weather conditions, such as high winds and flying debris. The interlayer within the laminated glass holds the glass fragments together upon impact, preventing them from shattering and entering the interior of a building.
Do you need a permit to install impact windows in Wisconsin?
Generally, a building permit is required in Wisconsin for the installation of impact windows, especially when they involve structural changes or upgrades to the building envelope, ensuring compliance with the Wisconsin Uniform Dwelling Code (UDC).
Can you install impact windows yourself?
While technically possible, self-installation of impact windows is strongly discouraged due to the critical nature of proper sealing, structural integration, and adherence to building codes. Professional installation by certified technicians ensures optimal performance and compliance, which is vital for maximizing the protective benefits.
How much does one impact window cost?
The cost of an individual impact window varies significantly based on its size, style, frame material, and the specific impact rating required by local building codes. Factors such as the complexity of the installation and any necessary structural modifications also influence the final price. For precise cost considerations, we recommend obtaining a professional quote.
What are the drawbacks of impact windows?
The primary drawbacks of impact windows often relate to their initial cost, which is higher than standard windows, and a slight reduction in visible light transmission due to the laminated interlayer. Some users also report a marginal decrease in acoustic insulation compared to specialized sound-reducing windows, though they still offer significant sound dampening.
What makes a manufacturer the best choice for impact windows in Milwaukee?
The best impact windows manufacturers for Milwaukee properties will provide products tested to meet stringent wind and impact resistance standards, such as ASTM E1886/E1996, and offer clear documentation of compliance with Wisconsin's building codes. Experience with the city's diverse architectural heritage is also a significant advantage.
