I have been looking for a formula to calculate the STC for a series of different window/glass combinations. In my situation, I have casement windows with 1/4" overall IG. I can insert a second pane of glass at 2" using the location of my internal screen track or at 6" where it would sit on the sill of the window. I have taken outside measurements with a professional microphone to get the frequency and loudness time series for overflight departing aircraft noise. I found that the curve reproduces jet backblast, with the loudest noise between 30Hz and 250Hz.

Bulk density is an indicator of Weight of a unit volume of a loose material (such as a powder or soil) to the same volume of water. Expressed in kilograms per cubic meter (kg/m3) or pounds per cubic foot (lb/ft3), it is a type of relative density and is used mainly in quality control, shipping, and soil analysis. Bulk density is a useful property of Refractory, which defines the material present in a given volume. An increase in bulk density of a given refractory increases its volume stability, its heat capacity, as well as resistance to slag penetration.

I am wondering if panels have a chip in an edge or corner, at what size do they present a risk of breakage? From what I have read,the compression and tension layers increase as glass thickness increases. If a panel shows damage and it did not break, I read the chip did not penetrate the tension zone. Is it therefore unlikely to break? What is the expected damage size measured along the edge and face in say a panel of 6mm compared to 19mm of a chip that is likely to fail?

Thank you.

I have the problem with the tempering line. Recently, our products have strain pattern so heavily. I know that is the quench mark. Any advice will help us so much.
Thank you.

I am currently looking for a video that details how curtain wall is installed and discusses various types of curtain wall available.

Does anyone know of any technical or scientific studies which show it is ok to muse co2 lasers to mark bullet resistant glass with a CE MARK or logo.

Looking for suppliers of Resin to laminate glass to Polycarbonet.

HI,
Our company install glass curtain wall for buildings, I am wondering if tempered glass is better than laminated glass or not in contruction. Anybody can help me to answer?

We can able to ship auto glass to Nigeria. If anybody interested, please let me know.
Thanks,

Green design, or the use of energy efficient and environmentally friendly products in design, has become a huge trend in the architectural community, and liberal use of glass is one of the signatures of this trend. Allowing natural daylight into the space using high performance glass cuts consumption of electricity and adds a cheery element to interior space.
