Gypsum industry news

US: Colin Hanson, one of the founders of gypsum wallboard moisture measurement expert Sensortech Systems, retired from his position of president of the company on 14 May 2020. A native of Southport in the north west of England, Colin Hanson established Sensortech Systems in Oxnard, California, along with Logan Mosteller and Bob Blankenship, in 1983. He had previously worked for leading moisture measurement equipment manufacturers in the UK and US and in the oil exploration sector in the UK.

Hanson was the pioneering developer behind Sensortech’s resonant frequency (RF) radio approach to moisture measurement. This offered higher accuracy, and hence control, to wallboard manufacturers, as it was more directly dependent on moisture content than the established techniques based on power-loss measurements. The RF approach has since risen to become the dominant approach to wallboard moisture measurement worldwide.

The company’s first product based on the RF approach was the ST-1100 moisture sensor range, which was replaced by the ST-2200 in 1992 and, subsequently, the ST-3300 range in 2018. Sensortech also produces the Instantaneous Moisture Profiling System (IMPS), which analyses moisture across the full width of the board, and has an extensive offering of near infra-red sensors. It most recently developed the Kiln Jam Detector for use inside board dryers.

As Sensortech grew in the 1980s and 1990s, Hanson took over the shareholdings of the other two directors. He became sole owner of the company in 1996. He sold Sensortech Systems to KPM Analytics on 14 May 2019, remaining as president until his retirement a year later. He will remain on hand in an advisory capacity and will continue to offer his insights and expertise to the company, with a focus on the development of existing and new products.

Speaking upon the sale of Sensortech to KPM, Hanson said, “There is a depth of talent within Sensortech, supplemented by KPM, that will provide a seamless transition to a successful future. KPM is putting resources into growing Sensortech, which is fantastic. The company has a development queue representing years of research but there are opportunities to accelerate that with KPM.”

Ron Geis, KPM Analytics’ President, has taken over the role of president of Sensortech Systems.

UK: British Gypsum says its wallboard capacity is at ‘approximately’ 80% of pre-coronavirus pandemic levels following the scaling up of its ‘Covid-19 safe’ operations and distribution plan. Managing director Matt Pullen said that the company’s plaster capacity was already at 80% and it was increasing supply volumes to merchant and distributor customers. It is continuing to allocate wallboard and plaster at lower levels than usual as it resumes normal production. It has also restarted taking new orders for its plasterboard recycling service. The subsidiary of Saint-Gobain shut down its non-essential operations in early April 2020 due to the coronavirus pandemic.

Switzerland: Saint-Gobain has started to sell its entire stake in Sika through its subsidiary Schenker-Winkler Holding (SWH). It previously acquired a 10.75% interest in Sika indirectly through the acquisition of 100% of SWH shares from the Burkard family in May 2018 as part of a global agreement with the Burkard family and Sika.

Saint-Gobain attempted to takeover Sika through acquiring a share of the company owned by the Burkard family in 2014. However, a legal counteraction followed and an attempt to transfer shares of Sika from the Burkard family was blocked by a Swiss court in late 2016. Saint-Gobain and Sika eventually ended the takeover attempt in May 2018 by retaining a 10.75% share in Sika, sales of other shares and other benefits. Following a two-year ‘lock-up period’ Saint-Gobain says it decided to dispose of its stake in Sika. It added that Sika chose not to exercise its right of first offer.

Spain: Knauf España has signed an agreement with the Arquitectes per l’Arquitectura association with the aim of supporting sustainable and universal architecture. The partnership compliments other initiatives Knauf holds in the country with the Higher Council of Colleges of Architects of Spain, the Green Building Council, the College of Architects of Madrid, the Alejandro de la Sota Foundations and Architecture and Society.
