How thick should hurricane impact glass?
How thick should hurricane impact glass?
A minimum frame depth of 2 3/4 inches on windows and 5 1/8 inches on sliding glass doors, with a minimal nominal wall thickness of . 062 aids the system in withstanding strong winds.
What kind of glass is hurricane proof?
laminated security glass
When we talk about hurricane-resistant windows, what we usually mean is laminated security glass. This is a special type of impact-resistant window glass consisting of a thermoplastic interlayer sandwiched between two outer layers of strong glass.
How thick should impact glass be?
Impact windows use thick laminated glass and sturdy framing materials, which result in a decrease in external noise by as much as 40%. Their overall thickness ranges from 7/16” to 9/16”, as compared to typical single pane glass measuring an average of 1/8”.
What are hurricane proof windows made of?
Hurricane rated windows are generally made using two sheets of tempered glass, which are bonded together to a thin plastic membrane usually made from polyvinyl butyral (PVB). The specific thickness of the plastic membrane depends on the type and strength of the hurricane window.
Can tempered glass withstand a hurricane?
This impact resistance makes laminated tempered glass ideal for situations where shatterproof glass is wanted to protect a home. This could be from repeated impacts from a would be intruder or from wind carried debris during severe wind storms.
How thick are PGT Windows?
DOUBLE-STRENGTH GLASS (DSB) is a single pane of glass 1/8” thick. This glass thickness is the minimum available in PGT products. PLATE GLASS is a single pane of glass 3/16” thick. This thicker glass is an available option for most PGT windows and is standard in the majority of PGT doors.
Is tempered glass the same as hurricane glass?
If tempered laminate glass is broken, it will break into small pieces, but is still be held together by the tough, but flexible plastic layer. Windows made with tempered laminated glass have the much higher strength of tempered glass.
What is the difference between tempered glass and hurricane glass?
Tempered glass is a heat treated glass. The glass is heated first, followed by the surface being cooled rapidly. Impact-resistant glass is created by use of a safety glaze for laminated glass. This type of glass is created by bonding together two or more panes of glass with a thin clear film between the panes.
What is the difference between hurricane windows and impact windows?
A standard hurricane window will be able to withstand the extreme pressure generated by hurricane-force winds, but it will shatter if struck by airborne debris. Impact windows are constructed with a durable laminate between the glass panes.
Are hurricane proof windows worth it?
Hurricane-resistant windows can increase your overall construction cost, but they offer great protection during the storm season. The investment may well pay for itself by preventing storm damage, and it can also allow you to qualify for discounted homeowners insurance rates.
What is impact glass?
What Is Impact Glass? Impact Glass is quite literally what it sounds like. It’s glass that is built with the intention to resist heavy impact. This impact may come from sleet or hail, or even from flying limbs and other debris during a storm.
What glass is high impact glass?
In order to withstand wind-borne debris or break-ins, high impact windows are made with heavy-duty frames and safety glass which are carefully sealed to keep the glass from breaking away from the frame. Safety glazing is designed to reduce or minimize the likelihood of injury to humans when the glass is broken.
What do you need to know about hurricane resistant glass?
Hurricane resistant glazing is meant to help protect the interior of a building from the high winds, strong rain and projectiles that form when a hurricane makes landfall. If a window or door is breached during a hurricane, wind and rain can penetrate the building and cause structural damage to the building.
What is the thickness of single strength glass?
The most common glass thicknesses are: SINGLE-STRENGTH GLASS (SSB) is a single pane of glass 3/32” thick. Most window and door manufacturers have moved away from using this glass thickness in their products, though some manufacturers continue to use it in their lines. DOUBLE-STRENGTH GLASS (DSB) is a single pane of glass 1/8” thick.
Where are hurricane impact glazing systems tested in Florida?
ASTM charts show the requirements of ASTM E1996, with the southern Florida counties of Broward and Miami Dade being in Wind Zone 4. Testing is carried out on the system which includes glass, frame, sealants and hardware. Our advanced interlayer technology is the thinnest of its kind in the hurricane-impact glazing market.
What is the latest standard for hurricane protection?
The latest national standard is the ASTM E1996 Standard Specification for Performance of Exterior Windows, Curtain Walls, Doors and Impact Protective Systems Impacted by Windborne Debris in Hurricanes.
