The development of spectrally selective glass tints and coatings has enhanced the solar and thermal properties of glass tremendously. When used in insulating glass units, in combination with argon or krypton gas fill, r-values greater than 4 and solar heat gain coefficients less than 0.3 are possible. Combined with relatively high light transmittance that can [...]

OK, so we have discussed the causes of thermal stress in glass and we have reviewed the basic types of glass (annealed, heat strengthened and tempered) used in building projects. Your question might be: How do these two discussions tie together?Well, not to beat around the bush, the most common reason that thermal stress breakage [...]

My previous entry ended with the promise of further discussions about thermally induced stress in glass–and we shall have those discussions. However, before we continue down that road, let’s spend a little time reviewing the three types of glass that are used in the fabrication of products for use in buildings. It will help us [...]

Glass is a wonderful building material! It is beautiful and enduring. It keeps the elements out, but lets the light in. And it gives building occupants a link to the outdoor environment that has proven psychological benefits. Unfortunately, glass also breaksThere are a number of common reasons that lead to glass breakage: excessive wind and/or [...]
