Premium X-Ray Shielding Glass



Premium X-Ray Shielding Glass

LX Premium X-Ray Shielding Lead Glass offers excellent impact resistance, radiation protection and visual clarity. LX Premium is high quality optical grade, lead barium type, X-ray shielding lead glass that consists of over 60% heavy metal oxide with a minimum of 55% PbO. It is inserted into two panels of protective sheet glass for easy cleaning.

"Believe you can and you're halfway there."

-Theodore Roosevelt

Due to the specialized nature of LX Premium, all glass must be cut to finished size at the factory. Please contact TGP regarding lead-time for your project.



As a high lead content glass, LX glass is more susceptible to staining as compared with normal window glass. Pay attention to the following precautions for installation and cleaning.

  1.  Do not stick anything on the surface of the LX glass during the installation. (When masking tape is used in caulking, remove it immediately after caulking and wipe off any tape traces with alcohol.)
  2.  Do not use a wet cloth or water to clean the LX glass. Immediately wipe off water in case the LX glass becomes wet.
  3.  When the LX glass becomes dirty or marked with fingerprints, polish the surface slightly hard with a dry, clean cloth like gauze using alcohol. Wipe the LX glass again afterwards with a new, dry and clean cloth to completely remove the alcohol remaining on the surface.

The time, in minutes or hours, that materials or assemblies can be expected to prevent flames and smoke from spreading.

As heat develops within the source area, pressure within the enclosed room begins to build relative to the pressure outside. Once the fire reaches equilibrium in the positive pressure zone, smoke, hot gases and flames are forced through any openings in the door or window assembly. Testing to the UL 10C standard more closely simulates real fire conditions.

Blocks radiant and conductive heat transfer from one side of the glass to the other. A required characteristic of glass used as a wall.

Classified and labeled by Underwriters Laboratories, Inc.® (UL), an independent product safety certification organization.

Immediately following a furnace test, heated glass is subjected to water from a fire hose. The cooling, impact and erosion created by the hose stream tests the integrity of the glass. In the U.S., the hose stream test is required for all fire ratings over 45 minutes (all fire ratings require it in Canada).

Available as a temperature rise door with Pilkington Pyrostop® fire-resistive-rated glass for 60-90 minute applications

Temperature rise doors provide a barrier to radiant and conductive heat transfer.

Available in stainless steel frame finish options for increased design flexibility.

Building codes clearly define hazardous locations where impact safety glass is required. Glass with this designation has been tested to meet impact safety requirements required for areas such as doors, sidelights, and areas close to the floor.

FireLite IGU is a fire-rated insulated glass ceramic unit that also complies with energy codes. It is designed for use in exterior applications where energy codes require an insulated product, or for interior applications with special needs such as sound reduction.

Withstands continuous temperatures to 1292° F for use in high efficiency heating appliances.

The ability of glass ceramic to withstand sudden heating, cooling, or both without cracking, shattering or exploding out of the frame.

The ability of the glass to stop various types of ammunition. Ratings are assigned in levels from 1 to 8, with a Level 8 rating being the highest (able to stop a 7.62mm rifle lead core full metal copper jacket, military ball).

The capacity of an element in a building structure to support a weight in addition to its own.

Listed and labeled by Intertek, an independent assurance, testing, inspection and certification organization.

Glazing designed to increase the amount of time required to gain entry. This additional time is intended to allow for the enactment of lock-down protocols and to allow for the arrival of emergency response teams. May be used in areas with high risk of prolonged attack or in critical areas such as vestibules. Forced entry resistant glazing should also resist penetration from hand-held or hand-thrown objects such as hammers, crowbars, bats, knives, bricks and rocks.
