For residents and businesses in Maryland, especially within the Baltimore metropolitan area, the climatic conditions present a clear need for robust fenestration. Impact windows, engineered with laminated glass that resists shattering upon impact and durable frame materials such as reinforced vinyl or extruded aluminum, provide essential protection against the severe weather events that can affect the region. These windows are designed to meet rigorous testing standards like ASTM E1996 and ASTM E1886, ensuring their performance against high wind pressures and projectile impacts common during coastal storms or severe thunderstorms.
In Maryland, the installation of impact windows generally requires a building permit, particularly in coastal zones or areas identified as having higher wind risks, to ensure compliance with state and local building codes. These codes often stipulate specific performance requirements for windows exposed to potential hurricane-force winds. Our process includes verifying the necessity of permits for your specific Baltimore location and ensuring the installation adheres to all applicable regulations, thereby guaranteeing the efficacy and safety of your impact window system and its compliance with Maryland's stringent building standards.
Common questions
What is an impact window?
An impact window is a specialized fenestration product designed to withstand severe weather events. It features laminated glass, consisting of a robust interlayer bonded between two panes of glass, and reinforced frames, typically made from strong materials like vinyl or aluminum. This construction prevents the glass from shattering upon impact, offering superior protection against windborne debris.
Do you need a permit to install impact windows in Maryland?
Yes, in Maryland, particularly in areas like Baltimore that may be subject to stricter wind load requirements, a permit is generally necessary for impact window installations. This ensures the work complies with state and local building codes designed for severe weather resilience. Proper permitting confirms that the installation meets all safety and performance standards mandated by authorities.
How much does one impact window cost?
The cost of an individual impact window is influenced by several factors, including the size of the unit, the specific frame material chosen (such as reinforced vinyl or aluminum), the desired tint or coatings, and the complexity of the installation. Features like specialized hardware or custom shapes can also affect the overall investment.

Can you install impact windows yourself?
While DIY installation of standard windows is sometimes feasible, impact windows require specialized knowledge and tools for proper installation to meet performance standards. Incorrect installation can compromise the window's ability to withstand impacts and wind pressure, potentially leading to catastrophic failure during a storm. Professional installation ensures structural integrity and adherence to manufacturer specifications.
What are the drawbacks of impact windows?
While offering significant benefits, potential drawbacks can include a higher initial cost compared to standard windows and a slightly altered aesthetic due to thicker frames or visible reinforcement. Some find the laminated glass may slightly reduce visible light transmission or offer less sound insulation than certain double-pane options without impact resistance. However, these are generally outweighed by enhanced safety and protection.
