Tentoma built and sold its first XL Power packiaging machine to replace an orbital wrapper.

Mexico: Saint-Gobain has agreed to acquire construction chemicals producer IMPAC. The company operates a construction chemicals plant in Monterrey, where it employs 630 people. The takeover aims to strengthen Saint-Gobain’s Latin American regional position and to accelerate its growth by growing its light and sustainable construction product range. The transaction is due to close in late 2021 or early 2022.

Spain: Saint-Gobain Placo has launched Placo Hermetic, a gypsum-based hermetic system for application to building envelopes. The company says that the product is the first of its kind to be gypsum-based that meets the Passivhaus standard. The Catalonia Institute of Construction Technology (ITEC) has certified the system with a Document of Suitability for Use (DAU).

The producer said “With this DAU, Saint-Gobain Placo continues to guarantee the suitability of its solutions, providing professionals in the sector with more sustainable and efficient systems that adapt to different projects and requirements, with total safety and reliability.”

Spain: Saint-Gobain Placo has announced the launch of 4PRO Active’Air, a laminated gypsum wallboard for use in ceilings. The company says that the product improves the air quality of rooms by absorbing pollutants with its Active’Air technology. The boards also have tapered edges for a join-free fit.

The producer said, “4PRO Activ'Air is presented as the most complete and efficient construction solution for the creation of continuous ceilings with a smooth and perfect finish, thanks to its fine edges, which increase the resistance between the joints and reduce the risk of cracks. In addition, it increases productivity thanks to its easy and fast installation, and offers great flexibility in construction, since it adapts to any type of project in the realisation of both regular and rounded shapes.”

India: USG Boral India hosted a virtual event for the launch of its new Sheetrock gypsum wallboard on 14 October 2020. The company said that the product is suited to a range of interior applications.

US: National Gypsum Company has published SoundBook 2.0, an updated version of its manual for technical information and architectural drawings of sound-rated assemblies for architects and contractors seeking to achieve required sound transmission class (STC) ratings on their projects. The publication includes details and drawings of 310 sound-rated assemblies for steel and wood stud construction, as well as for floor-ceiling applications. The book also features acoustical terms, concepts and proper installation methods for optimal sound control. The original SoundBook was published in 2015.

“Acoustical performance is one of the most popular topics covered by our Construction Services Team,” said John Bianchi, gypsum product manager for National Gypsum. National Gypsum’s goal in publishing SoundBook 2.0 is to provide architects, contractors and others involved in specifying products current information and illustrations on sound-rated wall, ceiling and floor assemblies.

National Gypsum has released several new acoustical gypsum products as part of the company’s SoundBreak XP family of products since the initial rollout of its SoundBreak XP Wall Board, including SoundBreak XP Retrofit Board, designed for use as an extra noise reducing layer over existing wallboard, and its most recent innovation, SoundBreak XP Ceiling Board, a board for floor-ceiling applications.

Germany: Schenck Process has added the ProFlex C100 to its range of ProFlex C family of products. The new offering is the smallest of the range and it is intended for small extruders. It is designed for flexibility allowing for a range of additives to be used, the asymmetric design is designed to prevent the bridging and plugging of sticky materials, it is equipped with an integrated gearbox for turndown ratios of up to 1:120 and it has a flexible wall liner massaged at eight points, which the manufacturer says allows a constant and accurate filling of the screw feed element.

The ProFlex C feeding system is used for the continuous feeding of bulk materials such as powder, granulates, pellets or fibers. The series is targeted for the compound and masterbatch industries.

Spain: Knauf has launched its Knauf Fino product, a fine, high-performance for indoor use. It is classified as lightweight construction gypsum C7 / 20/2 according to the UNE-EN 13279-1 standard. It has CE Marking.

Germany: Haver & Boecker is focusing on its Adams packaging product line for the Powtech trade fair taking place in early April 2019 in Nuremberg. The company says that the system offers the clean packaging of powdery, bulk products into watertight polyethylene (PE) packaging. The closed packaging protects products from loss and secures the quality against environmental impacts.

"Manufacturers are producing and packaging where the raw materials are located, which often means in countries with special climatic conditions. The packaged products are also exposed to extreme environmental conditions during global transport. This is precisely why the packaging has to withstand these conditions and absolutely protect the product," said Robert Brüggemann, Business Unit Head at Haver Chemicals.

Haver & Boecker’s Machinery Division is exhibiting at Powtech with a sustainability and resource conservation focus along with the motto ‘perfect Flow for our blue planet."

US: Underwriters Laboratories (UL) has completed fire performance evaluation on some of USG’s Sheetrock Brand EcoSmart Panel products. The testing concluded that 15.9mm USG Sheetrock Brand EcoSmart Panels Firecode X (UL Type ULIX) and USG Sheetrock Brand EcoSmart Panels Mold Tough Firecode X (UL Type ULIX) is specified in more than 260 fire-rated wall, column, and floor- and roof-ceiling UL designs in which Type X or Type C panels are required.

“Quickly and accurately identifying gypsum panel types in the field – especially after the panels have been hung and the joints are finished – can be challenging. Consequently, fire performance may be compromised if Type X panels are inadvertently hung as the ceiling membrane, whether in steel or wood construction, when Type C panels are required,” said Nestor Sanchez, senior manager, building science at USG.
