Bigger Glass, Better View
Monolithic Glass is a single lite of glass that is typically used in the construction of the final fabricated product.
Monolithic glass is also used for decoration purpose individually, like wall background, balustrade handrail, store front, office partition, glass door, etc. Meanwhile, it is must be tempered or heat treated.
We use clear and tinted float glass substrates from all the major China float glass manufacturing companies.
A monolithic glass product is enhanced for strength, design and aesthetics. Additionally, monolithic glass is used to fabricate insulating and laminated glass products.
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury.
Safety glass is a kind of glass that is not broken by violent vibration or impact, and will not splash and hurt people even if it is broken. The “Regulations on Building Safety Glass Management” defines it as such and stipulates that: outside windows of 7-story and above buildings, window glass with an area greater than 1.5m2, or floor-to-ceiling windows, curtain walls, and inclined assembly windows with the bottom edge of the glass less than 500mm from the final decoration surface , Various types of ceilings, suspended ceilings, sightseeing elevators and their outer enclosures, indoor partition screens, barriers of stair balcony platform corridors and atrium guardrails, floor panels used to bear pedestrians, entrances and exits of public buildings, entrances and halls, etc. , Safety glass must be used for other parts that are susceptible to impacts and impacts and cause human injury.

Glass with fully tempered surfaces is typically four times stronger than annealed glass and two times as strong as heat-strengthened glass of the same thickness, size and type. In the event that fully tempered glass is broken, it will break into fairly small pieces, reducing the chance for injury. In doing so, the small glass shards make it more likely that the glass will become separated from the opening.
In a specification, the designation for fully tempered glass is commonly abbreviated as FT.
Heat-strengthened glass is twice as strong as annealed glass of the same thickness, size and type. If broken, heat-strengthened glass will break into large shards similar to annealed glass. Because of this, the tendency for the glass to vacate the opening is reduced.
Fully tempered glass may break without warning due to the expansion of nickel sulfide inclusions (NiS) present within float glass. To avoid the risk of spontaneous breakage in fully tempered glass, a common practice is to avoid the use of tempered glass whenever possible.
Although the incidence of tempered glass breakage due to these inclusions is rare, greater publicity of their occurrence has resulted in an increased awareness of this phenomenon. In fact, limiting the use of tempered glass in commercial building applications has become the recommendation of a number of glass suppliers, including fsg.
In some situations however, tempered glass is required to meet safety glazing requirements or for added strength. In these cases, Viracon can perform a heat soak test to provide the added assurance that significant spontaneous breakage will not occur.
Focus Safety® gives you options when it comes to glass edgework. We have five polishing machine for ground and polished edges. Choose from: Seamed, Flat Belt Ground or Flat Belt Seamed, Flat Ground, Flat Polished or Mitered Edges.
Focus Safety® offers holes drilling capabilities starting at 1/4 inch.
Maximum Number of Holes: The maximum number of holes allowed in any lite of glass is ten (10).
Maximum Size: The maximum size of a hole can not be more than 1/3 the narrowest dimension of the glass.
Guideline for Holes Dimension
Minimum Size: Circular holes must have a diameter at least 1/16″ greater than the thickness of the glass, with 1/4″ (6mm) being the smallest hole allowed.
For holes that have a straight edge, or are non-circular, fillets are required in the corners. A fillet is a rounded corner from which the straight edge emerges. The radius of the fillet must be equal to or greater than the thickness of the glass, but not less than 1/2″.
Notches & Cutout
To provide you with notches and cutouts, the corners must have fillets. A fillet is a rounded corner of which the straight edge emerges. The radius of the fillet must be equal to or greater than the thickness of the glass, but not less than 1/2″.
All fabricated glass products with holes, notches and cutouts must incorporate tempered or heat-strengthened. Due to stresses created in the glass with these cutouts, annealed glass products are not appropriate. In addition, the guidelines below also apply for notch and cutout requirements:
- The depth or width of the notch or cutout can not have a dimension larger than 1/3 of the narrowest dimension of the lite.
- The leg length must be more than the depth of the notch.
- The leg length must be at least 3″.
- The depth of the notch must be less than the width.
- The inside corner(s) must have a radius equal to, or greater than the thickness of the glass, but not less then 1/2″.
