Hurricane Resistant Glass

Prel-Lam HRG

Prel-Lam Hurricane Resistant Glass* :

  • Provides high resistance to hurricanes and other bad weather that may occur in coastal areas.
  • Can withstand high wind loads for several hours.
  • Provided increased protection against projectile impacts blowed by wind.
  • Maintain the integrity of the building envelope during storms.

* Although no product can offer itself a complete protection against hurricanes and other storms, Prel-Lam HRG glass can withstand extreme weather when installed in a system designed for this purpose.



Caracteristics

  • Extreme weather in recent years have forced the adoption of new standards in some coastal regions. These standards are intended to increase the resistance of buildings in high wind loads as well as the impacts of projectiles blowed by wind.
  • During a hurricane, strong winds can lift objects and pull up building materials transforming them into dangerous projectiles. It has been shown that heavier debris can be thrown up to 9 m (30 ft) above the ground. Lighter debris, meanwhile, circulate generally from 9 m (30 ft) and more. The hurricane standards reflect this situation by requiring that windows resist to different impact strength depending on their location on the building.
  • To meet these standards, the whole window must be tested, either the glass sealed in its frame.

Components

Types of glass :

  • Clear, ultraclear, tinted
  • Low-E, reflective

Types of interlayers:

  • PVB, ionoplast

Standards*

  • International Building Codes (IBC and IRC)
  • Certification programs such as Florida Building Code (FBC) and Texas Department of Insurance (TDI)
  • Standards and testing methods such as Dade County TAS 201 and 203, ASTM E1886, ASTM E 1996 and SSTD 12.

*To meet these standards, the whole window must be tested, either the glass sealed in its frame.

Applications

  • Coastal areas where regulations require hurricane-resistant doors and window
  • Doors and windows for commercial and residential buildings
  • Curtain walls, atrium and skylights

1 : Small Missile Impact Resistant Test: glass installed in its frame must withstand the impacts of 30 steel balls of 2g followed by series of alternating pressure cycles.
2 : Large Missile Impact Resistant Test: glass installed in its frame must withstand 2 impacts of a 2 x 4 in piece of wood weighing 9lb followed by series of alternating pressure cycles.
3 : The maximum sizes do not imply that glass made in these dimensions will meet the requirements of the tests.
