Company Profile

Intertech Specialty Glass Co., Ltd. (ISG) was founded in 1996 with an objective of establishing a glass-manufacturing company. 

ISG initially began manufacturing only tempered glass and heat-strengthened glass. Our main concentration is to produce the best quality safety glass; hence, the tempered glass machine from Tamglass Ltd. in Finland, which is regarded as the world’s best tempered glass machine, was chosen. We have signed a contract with Tamglass Ltd. to maintain machine condition in the ultimate quality twice a year. Through our intention to produce the first-class quality products, our tempered glass has been received industrial standards —TIS 965-2537 and TIS 965-2560 — from the Thai Industrial Standards Institute. 

With years of strengthening experience, our ambition to deliver quality products has never been changed. We accordingly purchased a furnace from Tamglass Ltd. in Finland in 2010, although the cost is significantly different when compared with many brands. This high efficiency machine serves a large-scale production, which can produce tempered glass and heat-strengthened glass up to 2800 x 6000 millimeters.

For laminated glass, a machine from Lisec C.M.I., Italy, has been thoroughly selected for three main reasons: 1) the company is well-known for producing high quality manufacturing glass machines; 2)  this particular machine has the best automatic system; and 3) it can produce up to 2,800 x 6,000 millimeters.

Quality of film is another component that we never neglect. Amongst numerous selections of glass laminating films, we use films from only the best two laminating film manufacturers in the world, Dupont; USA and Solutia Inc.; USA. Besides, the Thai Industrial Standards Institute has also given industrial standards — TIS 1222-2537 and TIS 1222-2560 — to our laminated glass products. Our customers can then be confident in our superior product quality.  

Expansion continued in 2015 when we invested in an insulated glass machine from Bystronic Lenhardt GMBH, Germany, the best insulated glass machines producer. This machine can produce up to 2,700 x 5,000 millimeters and can automatically add inert gas while working.
