Extreme Weather Protection with Bifold Doors: Sound, Wind, and Impact Performance Explained

Home / Archive by category "BLOG"

Extreme weather events are becoming increasingly frequent, and architectural design can no longer focus solely on aesthetics. Protection against wind, noise, and impact is no longer a luxury, it’s a necessity, especially in coastal, urban, or high-exposure environments. 

In response, demand has surged for closure systems that combine structural performance, energy efficiency, and contemporary design. Among the most advanced solutions are bifold doors, which allow for full-space openings without compromising safety or indoor comfort. 

Several companies, including PRL, have developed Accordion Bifold Door systems (folding doors) that meet these demanding challenges with technical precision and architectural elegance. With ASTM and NFRC certifications, hurricane impact resistance, advanced sound insulation, and superior thermal performance, these doors offer much more than just a connection between indoor and outdoor spaces. 

👉 They protect what matters most. 

Whether for modern homes, commercial storefronts, or hotel developments, PRL’s folding door systems are designed to deliver visual continuity, reliable operation, and proven performance, even in the most extreme conditions. 

Extreme weather, whether hot or cold, can be prevented with the help of a barrier such as a bifold door

What Are Bifold Doors and Why Do They Matter in Extreme Climates? 

Folding doors, also known as bifold or accordion doors (depending on the commercial variant), are closure systems made up of multiple panels connected together that fold laterally to one or both sides when opened. Their design allows for wide, clean, and continuous openings, maximizing natural light and visual connection between indoor and outdoor spaces. 

Unlike traditional sliding doors, which typically limit usable opening space to around 50%, bifold doors enable a full-width opening, eliminating both physical and visual barriers. This makes them an ideal solution for projects that prioritize spatial flow, accessibility, and a stronger connection to the surrounding environment. 

In regions with extreme weather conditions, their value goes far beyond aesthetics or design appeal. High-performance folding systems—like those developed by PRL—are engineered to withstand wind pressure, water infiltration, sudden temperature shifts, and even windborne debris impacts, all without compromising operability or energy efficiency. 

Thanks to advanced engineering and certified components, modern folding doors provide not only architectural flexibility, but also a high level of structural protection and interior comfort, even under the most demanding conditions, such as hurricane-prone areas. 

👉 Want to learn more? Check out our article on What Bifold Doors Are. 

Certifications and Standards: The Performance Behind the Promise 

When it comes to extreme climates, a well-designed door is not enough. Today, it’s essential that every component is backed by recognized standards that ensure reliable performance. 

In this regard, PRL’s folding doors have undergone rigorous testing and comply with international ASTM and NFRC standards, ensuring structural integrity, thermal performance, and safety. 

ASTM Standards (American Society for Testing and Materials) 

These certifications validate how the system performs under various conditions such as wind, water, impact, and prolonged use. Key standards met by the PRL Accordion Bifold system include: 

  • ASTM E 283 – Measures air leakage rates through exterior doors. 
  • ASTM E 330 – Evaluates structural performance under wind load. 
  • ASTM E 331 / E 547 – Assess water penetration under static and cyclic pressure. 
  • ASTM E 1886 / E 1996 – Impact testing for hurricane conditions using windborne debris. 
  • ASTM F 842 – Measures forced entry resistance. 
  • ASTM B 221 – Specifies requirements for extruded aluminum used in framing systems. 

NFRC Standards (National Fenestration Rating Council) 

NFRC certifications focus on the thermal and solar performance of door systems: 

  • NFRC 100 – Measures the product’s thermal transmittance (U-factor). 
  • NFRC 200 – Determines solar heat gain coefficient (SHGC) and visible light transmittance (VT). 

Impact Resistance: Why It Matters and How It’s Tested 

In areas with extreme weather, especially those prone to hurricanes, impact resistance is no longer just an optional feature. It’s a fundamental requirement for the safety of exterior doors and windows. 

During severe storms, strong winds often propel debris at high speeds, causing damage that can compromise a building’s structural integrity or endanger its occupants. 

To prevent this, standardized testing protocols have been developed to simulate real-world conditions. The most recognized are ASTM E 1886 and ASTM E 1996, which combine high-velocity impact tests (such as wood projectiles) with positive and negative pressure cycles to replicate what happens during an intense storm. 

One of the most effective solutions for these scenarios is laminated glass with SentryGlass Plus (SGP) interlayer. Unlike tempered or standard laminated glass, SGP maintains its structural integrity even after breaking, helping protect interior spaces, preserve pressure balance, and prevent door or window failure. 

And it’s not just coastal regions that benefit. This level of protection is also critical in schools, hospitals, offices, and any construction located in areas where building codes demand high-impact performance. 

Bifold doors can withstand extreme weather, security risks and loud noises.

Acoustic Insulation: How Folding Doors Help Reduce Noise 

In addition to withstanding extreme weather conditions, exterior doors must also deliver strong acoustic performance, especially in urban areas, near busy roads, airports, or industrial zones. External noise can significantly affect the quality of life and indoor comfort of a home, office, or commercial space. 

The level of sound insulation in a folding door depends on several factors: the type of glass, perimeter seals, system airtightness, and installation quality. In the case of Accordion Bifold doors, double or triple-glazed units are used, with the option for acoustic laminated glass, which significantly reduces sound transmission from the outside. 

Moreover, the system is designed with high-compression seals and multi-point locking mechanisms, which help eliminate air and sound leaks, even across large openings. This not only enhances indoor acoustic comfort but also contributes to the space’s overall energy efficiency. 

For residential projects in noisy city environments or commercial spaces that demand quieter, more private interiors, folding doors with proper acoustic insulation offer a smart, functional, and visually appealing solution. 

Resistance to Wind, Water, and Air: What You Need to Know 

One of the most critical performance factors for any exterior door system is its ability to withstand wind pressure, prevent water infiltration, and maintain airtightness. These characteristics are especially important in high-rise buildings, coastal areas, or regions with heavy rains and strong gusts. 

For Accordion Bifold doors, these three factors have been tested according to internationally recognized standards: 

  • ASTM E 330 – Measures structural performance under wind load. 
  • ASTM E 331 and E 547 – Evaluate water penetration under static and cyclic pressure. 
  • ASTM E 283 – Analyzes air leakage through the system under specified pressure conditions. 

To meet these demanding conditions, the doors are equipped with high-compression perimeter seals, concealed drainage systems, and reinforced aluminum profiles with thermal breaks. Additionally, stainless steel rollers and fully sealed top or bottom tracks ensure smooth operation regardless of external conditions. 

 Energy Efficiency: How Folding Doors Contribute to Indoor Comfort 

Today, energy efficiency is a key consideration in any architectural project. A poorly insulated door can result in significant heat loss during winter and heat gain in summer, directly impacting energy consumption from heating or air conditioning systems. 

In the case of Accordion Bifold doors, the system is designed to deliver high thermal performance, thanks to three essential features: 

  • Thermally Broken System in aluminum profiles: a 30 mm internal polyamide barrier prevents temperature transfer between exterior and interior surfaces. 
  • Double or triple glazing with optional Low-E coating: this glass type helps control heat and UV transmission without sacrificing natural light. 
  • Airtight compression seals: these minimize air leakage, improving the thermal stability of the space. 

Additionally, the system’s thermal performance is backed by NFRC 100 (U-factor) and NFRC 200 (SHGC and visible light transmittance) certifications, providing reliable data for architects and builders when performing energy calculations. 

So, if you’re struggling with high energy bills due to air conditioning, this kind of door system could be a smart, energy-saving solution. 

Configuration and Design: How Versatile Are Folding Doors? 

One of the key advantages of folding doors is their ability to adapt to different architectural needs, whether in residential or commercial projects. 

Thanks to their modular design, it’s possible to configure systems with multiple panels that fold to one or both sides, allowing for wide openings without the need for intermediate structures. 

In the case of the PRL Accordion Bifold system, configurations of up to 14 panels per system are possible, with inward or outward opening. It also offers stacking options to the left, right, or split, depending on the space layout. 

Other important design features include: 

  • Top or bottom tracks: depending on project requirements, you can choose a bottom-rolling system (more stable in severe weather conditions) or a top-hung system (ideal for clear floor transitions). 
  • Flush threshold: allows for seamless transitions between indoor and outdoor areas, improving universal accessibility. 
  • Glass compatibility: supports a variety of glass types depending on the required level of security, thermal insulation, or acoustic performance. 

Folding doors have become an architectural solution that addresses not only aesthetic preferences but also increasingly demanding technical requirements. 

Their ability to provide full openings, structural resistance, thermal and acoustic insulation, and design flexibility makes them an ideal choice for residential, commercial, and institutional projects. 

In the face of extreme weather, such as coastal areas or regions with high winds and heavy rain, having a certified system makes a real difference. PRL’s Accordion Bifold doors, tested and certified under ASTM and NFRC standards, deliver proven protection and performance without compromising the look or functionality of a space. 

If you’re looking for a closure solution that combines contemporary design with energy efficiency and structural safety, high-performance folding doors are definitely worth considering.

Laminated Glass vs. Tempered Glass: Which Is Better for Security and Design?

Home / Archive by category "BLOG"

Choosing the right type of safety glass is important for architects, builders, and property owners who want to balance security, aesthetics, and performance.  

With rising concerns about break-ins, severe weather, and even noise pollution, laminated glass and tempered glass have become two of the most popular options in modern construction. However, despite both being classified as safety glass, they differ significantly in how they’re made, how they break, and where they perform best. 

Understanding these differences is essential to avoid costly mistakes and ensure your glass installation meets the needs of your space. Whether you’re planning to secure a storefront, upgrade residential windows, or add a sleek glass element to your interior design, this guide will walk you through the key distinctions between laminated glass and tempered glass, from strength and security to price and recommended applications. 

Laminated glass is chosen for impact protection, as it does not shatter into thousands of pieces.

All You Need to Know About Laminated Glass 

Now let’s learn all about this glass so you can decide if it’s a good fit for your project. 

What Is Laminated Glass? 

Laminated glass is made by bonding two or more layers of glass with a plastic interlayer, usually polyvinyl butyral (PVB). This interlayer holds the glass sheets together even when shattered, preventing dangerous shards from scattering. The result is a glass product that combines durability with enhanced safety features. 

Main Benefits of Laminated Glass 

Laminated glass offers many of these benefits. 

  • Sound Reduction: Laminated glass dampens sound, which is ideal for buildings near busy streets or in noisy environments. 
  • UV Protection: The plastic interlayer blocks up to 99% of harmful UV rays, helping protect interiors from fading. 
  • Design Options: The interlayer can incorporate decorative films, graphics, or colored layers, offering creative opportunities in architecture. 

Common Uses of Laminated Glass 

Laminated glass has some very specific uses. 

  • Skylights and overhead glazing to prevent falling glass hazards. 
  • High-rise building windows. 
  • Automotive windshields. 

All You Need to Know About Tempered Glass 

Now let’s learn all about this glass so you can decide if it’s a good fit for your project. 

What Is Tempered Glass? 

Tempered glass starts as regular (annealed) glass that is heated to high temperatures and then rapidly cooled in a controlled process called tempering. This thermal treatment increases its strength by putting the outer surfaces in compression and the inner core in tension.  

When it breaks, it shatters into small, blunt pieces rather than sharp, jagged shards, significantly reducing the risk of injury. 

Main Benefits of Tempered Glass 

Tempered glass offers many of these benefits. 

  • Impact Resistance: Tempered glass is about four to five times stronger than standard glass, making it highly resistant to impacts. 
  • Safety on Breakage: The characteristic “dice-like” shattering minimizes the danger of sharp edges. 
  • Thermal Resistance: It can withstand higher temperature changes without breaking compared to standard glass. 

Common Uses of Tempered Glass 

Tempered glass has some very specific uses.   

  • Side and rear windows in vehicles. 
  • Tabletops and shelves. 
  • Windows in high-rise buildings where safety glass is required by code. 
Both options offer significant advantages in terms of safety. One of the differences is the size of the two products.

Laminated Glass vs Tempered Glass: Key Differences 

While both laminated and tempered glass fall under the category of safety glass, they are designed for different needs and situations. Laminated glass is best when security, sound insulation, and UV protection are priorities, since its interlayer keeps broken pieces together and adds extra benefits.  

Tempered glass, on the other hand, is ideal where high impact resistance and breakage safety are needed, offering impressive strength but shattering completely into small, blunt fragments if broken. 

Below is a quick comparison highlighting the main differences:

What Is Laminated Glass and Why Is It Used in Modern Construction?

Home / Archive by category "BLOG"

In today’s construction landscape, safety, durability, and performance are no longer optional, they are expected. That’s where laminated glass comes in. 

Unlike regular glass, which shatters into sharp fragments, laminated glass remains in place, significantly reducing the risk of injury or damage. 

Because of these features, laminated glass is no longer limited to specialty applications. It’s now a standard material in modern architecture, from high-rise facades and skylights to storefronts, security glazing, and even interior partitions. 

In this article, we’ll explore what laminated glass is, how it’s made, where it’s used, and why it’s become an essential element in both residential and commercial construction. 

Laminated glass is one of the new ways to protect your home or workplace.

What is Laminated Glass and How  Is Made 

Laminated glass is a type of safety glass made by bonding two or more layers of glass with a resilient interlayer, most commonly polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This interlayer plays an important role in holding the glass layers together when broken, making laminated glass a reliable choice for safety, structural integrity, and sound insulation. 

Would you like to know how laminated glass is made? In most cases (although it depends greatly on the technology) 

  • Glass Preparation: The process begins with two sheets of annealed or heat-treated glass. These can vary in thickness depending on the intended application, from standard windowpanes to heavy-duty architectural panels. 
  • Interlayer Placement: A plastic interlayer (typically PVB or EVA) is carefully placed between the glass sheets. This interlayer may also include additional elements like colored films, acoustic layers, or UV filters. 
  • Assembly and Pre-Lamination: The glass and interlaye 
  • r are assembled into a “sandwich” and passed through rollers in a heated environment to remove air pockets and initiate bonding. This stage is known as pre-lamination. 
  • Autoclave Process: The assembled unit is then placed into an autoclave, a high-pressure, high-temperature chamber, where it undergoes final bonding. The heat and pressure ensure a permanent, optically clear, and uniform adhesion between the layers. 
  • Cooling and Quality Inspection: After the autoclave process, the laminated glass is cooled and inspected for clarity, strength, and defects. It may also be cut or shaped depending on the project’s specifications. 

Common Applications of Laminated Glass 

Thanks to its unique structure and superior performance, laminated glass is used across a wide range of commercial, residential, and industrial applications. Its versatility makes it a top choice for architects, contractors, and developers seeking both safety and design flexibility. 

Most Common Uses Include: 

✅ Storefronts and Curtain Walls: Offers increased security and impact resistance for high-traffic commercial spaces, while maintaining transparency and aesthetic appeal. 

✅ Windows and Doors: Ideal for residential and commercial buildings in areas prone to storms, earthquakes, or break-ins. 

✅ Skylights and Overhead Glazing: Increases safety in overhead applications, where falling glass could pose a serious risk. 

✅ Interior Partitions and Glass Walls: Combines acoustic insulation and visual separation with a modern, sleek design. 

✅ Glass Railings and Balustrades: Provides structural strength and fall protection without compromising visibility or style. 

✅ Soundproof Rooms and Studios: The acoustic properties of laminated glass make it suitable for conference rooms, studios, and buildings located in noisy environments. 

✅ Transportation and Automotive Use: Widely used in vehicle windshields, public transport, and even marine applications for enhanced passenger safety. 

✅ Banks, Embassies, and Secure Facilities: When combined with specialized interlayers, laminated glass can be used in bullet-resistant or blast-resistant glazing systems. 

✅ Specialty Applications: Including aquariums, museums, display cases, and animal enclosures, where safety, clarity, and strength are critical. 

There are several types of laminated glass, which provide protection against impacts, weather, and even bullets.

What are the most common types of laminated glass? 

Whether you’re specifying glass for a high-rise facade, interior partition, or impact-rated storefront, choosing the right laminated glass type is key to meeting both code and design requirements.
