Glass is generally suitable as a structural support however, even minor irregularities on the surface of a glass panel can compromise its tensile strength, however, glass lamination has created another level of safety within glass construction.

Structural glass is a term that refers to a frameless installation of glass where part of the structural load is taken by the glass itself rather than by a supporting frame. There are mainly three types of glass used for structural applications namely; annealed glass, heat-strengthened glass and toughened glass. Other types of glass used in construction are Sheet or flat glass, laminated glass, shatterproof glass, energy efficient glass, wired glass, tinted glass and toughened glass.

All fenestration products experience an element of heat loss due to the following aspects;

Radiation: heat energy is absorbed by the material and radiates to the cooler side.

Conduction: heat energy moves through solid materials

Convection: heat energy is transferred to the air between the materials

 Air leakage: heat energy is transferred to air moving through seals of gaps

Absolute adherence to all safety regulations set out by the industry governing bodies, NBR, SAGGA and SANS and international specifications ensures a product fit for use in residential and commercial construction projects.
