HOLES AND NOTCHES

Tecnoglass offers hole-drilling capabilities starting at 7mm thickness.

Maximum Number of Holes

幸运彩票Any given lite of glass has a maximum capacity of ten (10) holes.

Guidelines for Hole Dimensions

Minimum diameter:幸运彩票 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.

Maximum diameter:幸运彩票 The maximum diameter of a hole can not be more than 1/3 the narrowest dimension of the glass.

In the case of any holes that are non-circular or have straight edges, 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 5/16″.

Guidelines for Minimum Glass Width with Holes

幸运彩票Any glass containing holes to be adequately tempered must have a minimum width of 8”. This and all other requirements such as the dimensions of holes, their location and their spacing must be met simultaneously.

Guidelines for Hole Spacing

The distance from any edge of glass to the nearest point on the rim of the hole (x) must be twice the thickness of the glass.

幸运彩票The distance between holes must be 10mm (3/8″) or twice the thickness of the glass, whichever is greater.

Guidelines for Holes Placement Near Glass Corners

Holes near corners must be located so that the nearest edge of the hole is at least 4 times the thickness of the glass from the tip of the corner when the corner is 90° or more.

Notches

幸运彩票Fabricated on our Z. Bavelloni CNC Machine, Tecnoglass can supply you with more options for custom enhancements of monolithic glass. Please refer to the following guidelines when requesting your specially fabricated glass products.

Guidelines for Notches and Cutouts

Fillets on the corners are required in order to provide you with notches and cutouts, their radius must be equal to 5/16”. As mentioned previously, a fillet is a rounded corner of which the straight edge emerges.

Any fabricated glass products ordered with holes, notches and cutouts must be tempered or heat-strengthened. These cutouts create stress in the glass making annealed glass products not appropriate. In addition, the guidelines below also apply for notch and cutout requirements:

Fabrication Limitations

  • The depth or width of the notch or cutout cannot 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 5/16″ (8mm).
