Tempered Shower Enclosures by Glaz Tech

Tempered Glass by Glaz-Tech Industries

Equipped with state of the art technology, Glaz-Tech's capabilities to heat strengthen or temper glass has provided faster lead times and quality product for both commercial and residential applications. Glazers, project managers and architects can rely on various temperable products including standard clear glass, low-e, pattern, tinted and reflective glass products. Whether you are looking for a high volume of tempered shower enclosures, tempered windows, displays or knock out panels Glaz-Tech Industries provides innovative solutions so that your tempering projects remain consistent with quality.


  • Suitable where safety glazing is required.
  • Doors : patio, entrance, storm and sidelites
  • Windows : commercial / residential
  • Tub and shower enclosures
  • Skylights, paneling and handrails
  • Storefronts, displays and partitions
  • Table tops and fire knock-out panels


  • Approximately five times stronger than annealed glass of equal thickness.
  • Greater resistance to thermally induced stress than heat strengthened or annealed glass in IG units.
  • Color, chemical and light characteristics of glass remain unchanged after the heat treating process.

Safety Glass

Fully tempered glass is used in many applications because of its safety characteristics. Safety comes from strength and from a unique fracture pattern. Strength, which effectively resists wind pressure and impact, provides safety in many applications. When fully tempered glass breaks the glass fractures into small, relatively harmless fragments. This is called "dicing", and reduces the likelihood of injury to people as there are minimal jagged edges or sharp shards.

Tempered Processing

Manufacturing Considerations

Glass thickness from 1/8” through 3/4” can be tempered. Glass thickness from 1/8” through 1/4” are commonly heat-strengthened. All processing work such as cutting, edgework and drilling must be completed prior to tempering. Glass cannot be cut or worked after the tempering process.


GTI tempered glass can be processed in a variety of different styles, from the relatively simple ground or polished edges, to the more decorative profiled types of edgework. Other types of edgework may also be available upon request.

Holes & Notches

In order to temper glass with holes, the holes must be the same size or bigger than the glass thickness. Minimum diameter for 1/8” glass is 3/16”. Contact your sales representative with questions about other laminations regarding holes, notches and cutouts.

General Info

There are some characteristics of tempered glass, such as bow and warp, roller distortion, and others that are inherent to the tempering process, and are not considered defects. GTI is always improving ways to minimize these characteristics and to keep within ASTM standards 1048 and 1036.
