ES Windows deliver superior construction quality and enhanced protection
By default, all ES Windows product lines feature a minimum pressure rating of ±80 PSF—approximately 10% higher than competitors like PGT, CGI, and ECO, and significantly higher than Mr. Glass, Lawson, and other budget-impact window brands. This higher PSF rating provides enhanced protection.
As a premium brand, ES Windows offers numerous options and add-ons, including reinforced aluminum and argon gas insulation, enabling customers to choose both stronger and more energy-efficient hurricane windows.
ES Windows products have undergone rigorous testing to validate their durability and performance. Their use in over 27 countries demonstrates their global acceptance and reliability.
ES Windows offers premium upgrades at no additional cost
ES Windows stands out by including a range of premium upgrades as standard that you’d normally have to pay extra for with brands like Mr Glass and Lawson (if they even offer the upgrade). They use heavy-duty aluminum frames with a premium powder-coat finish, ensuring a long-lasting and durable finish without worry of premature fading or rusting. Their products feature corrosion-resistant stainless steel hardware and fasteners, high-quality seals, precise assembly for superior weatherproofing, and advanced glass technologies like true-gray tinted Low-E glass and insulated, double-pane impact glass. Additionally, ES offers thermally broken frames, multi-point locking systems for enhanced security, a variety of architectural shapes with slim sightlines for a modern aesthetic, and a single-source warranty through Tecnoglass, ensuring top-notch quality and long-term peace of mind—all built into the product without the extra 15–20% cost seen with competitors.

ES Windows’ Features and Additional Options
ES Windows constructs its impact-resistant windows and doors using high-grade, heavy-duty aluminum frames designed for maximum strength and longevity. Unlike thinner or lower-density aluminum used in some budget hurricane windows, ES’s frames are engineered to withstand extreme wind pressures and structural loads, often exceeding the strictest Miami-Dade HVHZ (High-Velocity Hurricane Zone) requirements. The thicker aluminum profiles not only contribute to better hurricane resistance but also allow for larger window and door spans without compromising durability. This robust construction ensures that ES products retain their shape and function for decades, resisting warping, bending, or structural fatigue even in harsh coastal environments.
To ensure long-lasting durability and aesthetic appeal, ES Windows applies a premium Kynar or Durastar powder-coat finish to all of their Impact Window aluminum frames as a standard feature. This high-performance coating meets AAMA 2605 specifications, providing exceptional resistance against UV exposure, salt spray, and weather-related deterioration. Unlike standard painted finishes, which can fade, chalk, or peel over time, Kynar and Durastar coatings maintain their rich color and gloss for decades with minimal maintenance. This feature is particularly beneficial for coastal homes exposed to intense sunlight and salty air, preventing corrosion and extending the lifespan of the hurricane windows.
All ES Windows come standard with stainless-steel hardware and corrosion-resistant fasteners, ensuring long-term reliability in high-humidity and salt-air environments. Cheaper impact window brands often use plated steel or zinc-coated hardware, which can rust and degrade over time, leading to operational failures. By incorporating marine-grade stainless steel components, ES prevents issues like pitting, discoloration, and mechanical breakdowns, ensuring smooth operation and security for years to come. This feature is especially critical in hurricane-prone regions where exposure to moisture and salty conditions accelerates corrosion in inferior hardware systems.
ES Windows ensures superior weatherproofing and airtight construction by utilizing high-performance silicone gaskets, continuous perimeter seals, and precision-assembled joints. These advanced sealing techniques significantly reduce air and water infiltration, making the windows more energy-efficient and resistant to leaks during storms. Compared to standard industry offerings, which may use basic rubber or foam weatherstripping prone to deterioration, ES employs high-quality compression seals designed to maintain their integrity for years. This not only enhances water resistance during hurricanes but also contributes to quieter interiors by reducing outside noise penetration.
ES Windows offers Low-E glass with proprietary gray tints as a standard feature, providing superior solar control without the greenish hue commonly found in traditional Low-E coatings. Many manufacturers struggle to combine tinted laminated glass with Low-E technology, often forcing customers to choose between energy efficiency or aesthetic appeal. ES’s advanced glass processing techniques allow for neutral gray-tinted Low-E glass, which reduces glare and solar heat gain while preserving true-to-life color clarity. This results in enhanced thermal performance, UV protection, and a sleek, modern look that complements luxury home designs.
For improved energy efficiency and sound insulation, ES Windows offers double-pane, insulated impact glass configurations as part of their standard product lineup. Unlike single-pane laminated impact windows, which provide protection but minimal thermal resistance, ES’s insulated laminated units feature an air or gas-filled cavity between two panes of glass, significantly reducing heat transfer. This helps maintain indoor temperatures, reducing reliance on air conditioning and lowering energy costs. Additionally, the insulated glass construction enhances soundproofing, making ES windows ideal for homeowners who want a quieter, more comfortable living environment.
ES Windows incorporates thermally broken aluminum impact window frames in select high-performance impact window models to further enhance energy efficiency. By integrating an insulating barrier between the interior and exterior sections of the aluminum frame, thermal breaks reduce heat conductivity, preventing heat loss in winter and excessive heat gain in summer. Standard aluminum frames, while strong, can act as thermal bridges, allowing temperature transfer that increases energy consumption. ES’s thermally broken frames help maintain indoor comfort levels and improve the overall U-value of the window, making them comparable to vinyl-framed options but with the strength and durability of aluminum.
Security is a top priority in ES impact doors, which come equipped with multi-point locking systems as a standard feature. Unlike traditional single-point locks, which secure only one area of a door, ES’s multi-point system secures the hurricane door at multiple locations—typically at the top, middle, and bottom—providing increased resistance to forced entry and storm winds. This robust locking mechanism not only improves home security but also ensures a tighter seal, reducing air infiltration and improving energy efficiency. Many competing impact doors offer multi-point locks only as an upgrade, while ES includes this superior security feature at no additional cost.
ES Windows provides a wide range of architectural impact window shapes and custom sizes, allowing homeowners to achieve distinctive and elegant designs without additional fabrication costs. Their impact-rated fixed windows are available in geometric shapes such as arches, circles, trapezoids, and custom designs to fit unique architectural styles. While some manufacturers limit their shape offerings or charge significantly more for custom configurations, ES Windows integrates these design options into their standard product lineup. This flexibility is particularly valuable for luxury residences that demand bold, visually striking window layouts without sacrificing hurricane resistance.
One of ES Windows’ standout design features is its minimalist, slim-profile aluminum hurricane window frames, which maximize glass area and create a sleek, contemporary aesthetic. Unlike bulky-framed impact windows that obstruct views, ES designs its windows with narrower sightlines, allowing for a more seamless connection between indoor and outdoor spaces. This is particularly beneficial in large fixed windows, sliding doors, and multi-panel configurations, where maximizing natural light and visibility is a priority. By maintaining structural integrity while minimizing frame bulk, ES Windows achieves a modern, high-end look that enhances both functionality and curb appeal.
Premium impact window systems, such as those offered by ES Windows, are engineered to support larger spans without compromising structural integrity. This means that designers can install wider windows with fewer interruptions from mullions or framing elements, resulting in a more open and seamless view. The robust construction—including heavier, laminated glass and reinforced frames—ensures that these larger spans can withstand extreme wind pressures and impact forces, making them ideal for luxury residences in high-risk areas.
From an aesthetic perspective, larger impact window spans provide a sleek, modern look that enhances natural light and maximizes unobstructed views of the surrounding landscape. For luxury homeowners, this translates to a refined architectural statement that combines form and function. The ability to integrate expansive glass areas without sacrificing performance not only elevates the visual appeal of a home but also contributes to an overall sense of spaciousness and openness, making it a highly sought-after design element in premium construction projects.

Mr. Glass and Lawson Windows specialize in budget-friendly product lines
Mr. Glass and Lawson position themselves as budget-friendly brands in the impact window and door market, offering solutions that meet basic hurricane protection standards. Mr. Glass’s MG series includes sliding doors, single-hung windows, French doors, and horizontal sliders—all designed to provide essential protection against hurricane-force winds and debris. Lawson follows a similar approach, emphasizing affordability while meeting required impact resistance and performance criteria.
While these brands offer cost-effective options with simpler materials and construction methods, they face some challenges. Customer feedback—particularly regarding Mr. Glass—has revealed issues with inconsistent installation quality and poor post-installation service. Though they provide an accessible entry point for hurricane-resistant products, buyers should carefully consider these factors against the long-term benefits and reliability offered by premium brands.
Lawson & Mr. Glass’ focus is on meeting the minimum to meet impact window regulations and reduce cost
While Mr. Glass products are designed to meet hurricane standards, they do so with less of the over-engineering seen in premium products. They focus on delivering a product that works without the additional safety margins. While they are still undoubtedly safer than traditional windows during a hurricane, they just focus on meeting the minimum standards to achieve impact-rated certification, and are not focused on exceeding the minimum requirements set by the state or local jurisdictions.
Reported customer service issues
Many Mr. Glass customers in particular, have reported significant issues with their customer service and warranty service, which may impact your ability to receive prompt customer support resolutions and critical warranty service in the event of an issue in the future.


Budget brands like Lawson and Mr. Glass typically fall short on strength, durability and customization
While Mr. Glass and Lawson provide windows and doors that meet the basic industry standards for impact resistance and energy efficiency, they generally offer fewer premium features as part of their standard packages. For instance, these brands typically use reinforced aluminum and standard impact-resistant glass without the advanced upgrades found in higher-end products. They tend to limit customization options such as specialized finishes or architectural shapes, meaning homeowners might only receive basic frame colors and a limited range of design styles. Advanced features like premium powder-coat finishes (e.g., Kynar or Durastar), heat-strengthened or insulated double-pane glass, and thermally broken frames are usually not included as standard. Instead, these features are often reserved as optional add-ons—if offered at all—which can significantly increase the overall cost.
In addition to the core materials, Mr. Glass and Lawson often fall short in the area of hardware and warranty support when compared to premium brands. While they do use corrosion-resistant hardware and provide multi-point locking systems for safety, these components are generally more basic and may not meet the performance levels seen in higher-end offerings. Premium brands like ES Windows integrate features such as stainless-steel hardware, advanced sealing systems, and even a single-source warranty backed by integrated glass manufacturing (via partnerships like that with Tecnoglass). In contrast, the warranties from Mr. Glass and Lawson are typically less comprehensive, and their after-sales support and installation processes have received mixed reviews from customers. This means that while they can be a cost-effective option for basic impact protection, buyers looking for long-term performance, enhanced design options, and robust support may find that the extra investments required for premium upgrades can quickly add up with Mr. Glass and Lawson.
