Whether glass block windows need hurricane shutters depends entirely on how they were engineered and certified.
Glass block windows offer excellent privacy and security, but they come with significant drawbacks, including zero airflow, obstructed views, high weight, and the fact that they are extremely difficult and expensive to remove once installed.
Glass blocks are not outdated—they are experiencing a major resurgence in architecture and interior design. While heavily associated with the 1980s, today's glass blocks feature updated finishes (like frosted or tinted glass) and serve as functional, light-diffusing, and private statement features in modern homes.
The Strength of Concrete Block
It can withstand winds up to 250 miles per hour and provide extra security during hurricanes, tornadoes and even earthquakes.
Seves Glass Block has engineered a high-performance window that provides effective protection against air pressure and flying debris caused by tornado-force winds. The following information can assist you in the design and incorporation of these windows into your projects.
Yes, specialized impact-rated glass block windows are highly effective for hurricane protection, often eliminating the need for storm shutters. However, standard glass block windows are not hurricane-proof, so proper certification and installation are required.
The first and most common cause of death in a tornado is blunt force trauma from flying debris. High winds turn everyday objects like lumber, glass, vehicles, and bricks into lethal missiles traveling over 150 mph. Being struck in the head or chest by these objects or by collapsing structures causes immediate fatalities.
Yes, a house can withstand a Category 5 hurricane, but only if it is specifically engineered and constructed to resist winds over 157 mph and severe debris impacts. Standard wood-frame homes frequently fail, so surviving these storms requires specialized building techniques.
For example, many areas mandate that structures withstand winds between 130 and 180 mph, depending on their location and risk level. Concrete block homes often meet or exceed these standards, withstanding up to 250 mile per hour wind.
Most homes in the US aren't built entirely of concrete because wood is faster, cheaper, and offers greater flexibility for the country's housing demands. While US homes almost always use concrete for foundations and basements, the above-ground structure is typically "stick-framed" (wood) for several practical reasons.
To replace glass block windows while maintaining privacy and light, use acrylic blocks for a lightweight, energy-efficient match, obscure/frosted glass for a sleeker look, or privacy films applied to standard windows for a budget-friendly DIY alternative.
Yes, glass blocks are making a major comeback in both residential and commercial design. Once considered a dated retro relic, they are being reimagined by designers who love their sculptural look and ability to balance maximum natural light with complete privacy.
A home often looks outdated when it features overused, location-specific trends from past decades, obviously artificial materials, or lighting and color schemes that lack depth. The most common culprits range from heavy architectural finishes to specific décor and hardware choices.
Factory-built glass block windows are eligible for the ENERGY STAR, but many glass block windows are built onsite. If you are purchasing glass block windows, look for the ENERGY STAR label to determine if the product is certified.
Glass block windows are absolutely worth it if you prioritize privacy, security, and low maintenance in spaces like basements, garages, and bathrooms. However, because they are stationary and lack ventilation, they aren't ideal for every room. The average installation costs range from $500 to $1,000 per window.
Generally, no, you cannot see through glass block windows; they are designed to offer high privacy by distorting images while allowing natural light to pass through. While you can see blurry shapes, light, or motion, you cannot make out clear details.
The most hurricane-resistant structure is a reinforced concrete or steel-framed monolithic dome. Its curved aerodynamic shape deflects high-velocity winds, while steel-reinforced concrete prevents structural collapse from massive debris impacts, storm surges, and winds exceeding 150 mph.
Standard residential windows typically withstand wind speeds of 70 to 80 mph before direct wind pressure causes them to shatter. However, they can break at lower speeds (around 50 mph) if struck by flying debris or if sudden changes in pressure occur during severe storms.
A house is typically deemed "unrepairable" (or a "teardown") when the cost of restoring it exceeds its eventual market value, or when severe structural and environmental damage makes it a safety hazard. The most common reasons include:
A hypothetical Category 7 hurricane would be a catastrophic, planet-altering storm, featuring sustained winds between 214 and 245 mph (345–394 km/h). It would cause absolute, apocalyptic devastation far beyond the current maximum rating of a Category 5, with wind fields spanning hundreds of miles and storm surges exceeding 30 feet.
The Gulf coast of Mississippi suffered extremely severe damage from the impact of Hurricane Katrina on August 29, leaving 238 people dead, 67 missing, and billions of dollars in damage: bridges, barges, boats, piers, houses, and cars were washed inland.
Yes, an F5 (or EF5) tornado can easily destroy a brick house. In a direct hit, the extreme winds of up to 300 mph and intense pressure changes can obliterate above-ground man-made structures, sweeping them down to their foundations.
There are only 3 states that have zero as an average. Alaska, Hawaii, and Rhode Island. But, all three have recorded tornadoes happening. California, Oregon, and Washington do have tornadoes every year. Mostly these are landspout type tornadoes.
During a tornado, you should never try to outrun the storm in a vehicle, take shelter under a highway overpass, open your windows to "equalize pressure," or stay in a mobile home. These actions drastically increase your risk of severe injury or death from flying debris.
The term "Finger of God" does not refer to a single specific tornado. Instead, it is a nickname used by meteorologists and storm chasers to describe any maximum-rated (F5 or EF5) tornado, the most powerful and destructive classification on the Fujita scale.
