New glass in the picture appears this week • Glass in the picture

The new Glass in the Picture (GIB # 3 – June 2022) is coming out this week. The edition is again filled with current events and backgrounds from the flat glass world. Our bar is set high because we want to help entrepreneurs in the field of flat glass and their employees to further professionalize. A selection of the topics.

Glass company (always) responsible

Working with glass is a challenging profession. Making glass, cutting, finishing, transporting, dealing with it, also placing the end product and providing service afterwards. Seven common steps in the business chain. And then we may forget the most important thing: advice. There is a lot involved in applying flat glass correctly from raw material (sand) to end product (window in the home). And with all these steps, the question arises: How far does the responsibility of the glass company go?

Glass Day 2022 on innovation flat glass

Eisma Bouwmedia is arranging a GLASS DAY at AFAS in Leusden on Thursday 9 June. Glass has been called the most innovative building material. The material develops at lightning speed and so are the areas of application. Every reason to, in line with the success of other Eisma events, such as the Houtdag and SchildersVakprijs, update the ‘passion for glass’ market. GLASSDAY 2022 shows the innovative power of flat glass. In the latest issue an overview of the presentation of all presenters.

The Valley mountain village with hanging glass ponds

The Valley residential and office tower is located on Amsterdam Zuidas, right next to the A 10. The design is realized by MVRDV and does away with the anonymous shiny corporate facades that the country is full of. The building got a contextual facade. Kingspan Light + Air made two glass roofs that act as a permanent pond. In addition to the water, one pond also carries the weight of a glass passage. For maximum transparency, glass fins support the glass roofs.

Test monument glass for breakthrough safety

The Glass Knowledge Center has, on behalf of Bouwbedrijf Kreeft, the main contractor for hull restoration and recycling of the ENKA Poortgebouw in Ede, tested the fallout safety of a special frame and a window. It is wooden frames glazed with thin multi-leaf monument glass, one of which is laminated. Putty affects the films in laminated glass, but does the kiter replacement sealant have sufficient adhesive strength to make the pane fall through? In addition, there was also the question of whether the window sash system would impair the strength of the frame or the window construction and thus have a negative impact on fall safety.

Windows misplaced

The triple glazing of a residential complex, which was completed at the end of November 2021, was examined by the Glass Knowledge Center with the aim of assessing the method of glass installation. The windows to be inspected were floor-to-ceiling windows on the first, second and third floors. The windows thus functioned as storey partitions at a height difference, whereby the ‘fall-proof’ glass plate had to be on the attack side (in this case the inside of the house). The stated composition of the glass was 4 (13) 4 (13) 44.2 with heat reflective coatings in positions 2 and 5. During the glass thickness measurements it was found that the pane was placed the wrong way. The 44.2 laminated glass turned out to be the outer glass plate, while the inner glass plate was made of float glass. Does the 3-pane need to be replaced correctly? You can read the answer in the section From practice in glass in the picture.

Manufacture of flat glass climate-neutral

Saint-Gobain Glass claims to have produced the first completely green flat glass. The French producer has used 100 percent ‘cullet’ (glass shards) and biogas in its float glass factory in Aniche in northern France. A world first. The manufacture of glass requires a huge amount of energy, especially gas. Production also requires a lot of raw material, especially sand, although there is (still) plenty of it. Who does not dream of CO2-neutral flat glass? Manufacturers are investing heavily to make that dream come true. For example, one of the world’s first climate-neutral glass factories is to be built in western Germany. Pilkington also did a test with hydrogen in the UK earlier this year, but that was only for a few days. In Aniche, positive tests have now been carried out for a week using green energy and only waste.

‘Spontaneous glass breakage’ not so spontaneous

How can it happen that several windows ‘spontaneously’ break in a house since it was built, the house was completed in 1999? The fracture pattern of these windows is largely the same. The house has wooden frames which are divided into rooms, so windows with a size of only 250 x 500 millimeters are used. The glass breaks occurred in random years, but with a common denominator, namely: during the glass break there was a low outdoor temperature, whereby the red line of the thermometer had dropped to below the ‘zero degrees Celsius point’. The Glass Knowledge Center was asked to find out the cause of these broken glass. You can read the whole case in the section From practice in glass in pictures.

Living the Glass Age: art, innovation and construction

The event Living The Glass Age of the UNexpected Glass Foundation is planned from 7 to 29 October in Eemklooster in Amersfoort. The concept of a ‘crossover event’ between art, innovation and construction arose as a result of discussions between glass artists Titia Felderhof and Krista Israel with the three owners of Het Eemklooster: Plecht Vosch West, ABC Vastgoed and EarthY. UNexpected Glass Foundation and the construction world have one big common denominator: glass.
