Safety
Prevents glass shards from becoming dangerous projectiles during storms. Also provides a level of burglary and forced-entry resistance protection.
Hurricane Glass
Hurricane impact glass from Thompson Innovative Glass is specially designed laminated glass that can withstand high winds, flying debris, and extreme pressure changes during hurricanes and severe storms.
Hurricane protective glass
Thompson Innovative Glass manufactures Hurricane protective glass, also known as impact-resistant glass. This product is specially designed to withstand the extreme forces associated with hurricanes and severe storms. It protects buildings and occupants from high winds, flying debris, and pressure changes, ensuring safety and maintaining the integrity of the building envelope.
Key Features
Laminated Construction
Hurricane protective glass typically consists of two or more glass layers bonded together with a tough, flexible high adhesion interlayer (commonly special storm interlayers or ionoplast). The interlayer will holds the glass together in post breakage scenarios, preventing glass shards from flying.
Durability
The glass is designed to protect people and from windborne flying debris and to meet building requirements.
Pressure Resistance
It is engineered to withstand the fluctuating pressures caused by hurricane-force winds, reducing the risk of window blowout.
Types of Hurricane Protective Glass
Monolithic Laminated Glass
Two layers of glass bonded together with a storm grade interlayer. Used in applications where thermal performance isn't required.
Insulated Laminated Glass (IGU)
Combines Hurricane protective laminated glass with Low-E coated glass for enhanced thermal performance, commonly used in modern building envelopes to meet thermal performance building requirements.
Key Benefits
Structural Integrity
Helps maintain the building envelope during hurricanes, reducing the risk of catastrophic failure from wind pressures.
Sound Reduction
The laminated glass dampens sound, improving acoustic control performance.
Frequently Asked Questions About Hurricane Glass
What is hurricane impact glass?
Hurricane impact glass is specially designed laminated glass that can withstand high winds, flying debris, and extreme pressure changes during hurricanes and severe storms. It consists of two or more glass layers bonded with a durable interlayer, usually polyvinyl butyral (PVB) or ionoplast.
How does hurricane impact glass work?
Impact glass absorbs the force of flying debris and high winds, preventing shattering. Even if the outer layer cracks, the interlayer holds the glass together, keeping the building envelope intact and reducing the risk of structural failure.
Is hurricane glass the same as tempered glass?
No, hurricane impact glass is different from tempered glass. While tempered glass is designed to break into small, less harmful pieces, impact glass is laminated, meaning it stays intact even if cracked.
What wind speeds can hurricane glass withstand?
Hurricane glass is tested to withstand wind speeds up to 200 mph or more, depending on the rating. It must meet impact standards set by organizations like the Miami-Dade County NOA (Notice of Acceptance) and ASTM International.
What are the different impact ratings for hurricane glass?
Hurricane impact glass is typically rated for Large Missile Impact (Level D) and Small Missile Impact (Level C) per ASTM E1996 and ASTM E1886 standards. Large missile-rated glass is tested with a 9-lb 2x4 traveling at 34 mph, while small missile-rated glass is tested with steel ball bearings.
Does impact glass provide protection against pressure changes during storms?
Yes, hurricane impact glass is designed to withstand extreme pressure fluctuations, reducing the likelihood of catastrophic failure due to wind pressure changes.
Can hurricane glass be installed in any type of window or door?
Hurricane impact glass is commonly installed in hurricane-rated windows, doors, storefronts, and curtain walls. However, the entire framing system must also meet impact-resistant standards.
Is hurricane impact glass more expensive than regular glass?
Yes, impact glass is more expensive due to its enhanced materials and manufacturing process. However, it can lower insurance premiums and eliminate the need for storm shutters, making it a worthwhile investment.
Can impact glass break?
Yes, impact glass can crack under extreme force, but it will remain intact due to the interlayer, preventing dangerous shards from becoming airborne.
