Insulation industry news from Global Insulation

US: Saint-Gobain North America has started a program where windshield glass scraps are recycled and reused in the production of insulation. Waste glass from the company’s Saint-Gobain Sekurit’s unit at Garden Grove in California is sent to CertainTeed Insulation’s facility at Chowchilla, where it is use to make fibreglass insulation. Saint-Gobain is working with Shark Solutions on the project. The initiative started earlier in 2022.

US: Knauf Insulation is celebrating the 20th anniversary of the beginning of operations at its Shasta Lake glass wool insulation plant in California. Local press has reported that the company increased its capacity by 70% over the past two decades. Today, the Shasta Lake plant employs 156 people. It has implemented sustainable practices in its production, including the use of ECOSE Technology plant-based binders in the place of petrochemical alternatives. It also recycles 600,000 glass bottles daily, constituting 50% of its glass consumption. This presented the plant with difficulties when Covid-19 lockdowns reduced local waste glass generation.

US: Saint-Gobain plans to spend US$32m towards to upgrade to CertainTeed’s Chowchilla glasswool plant in California. The investment is part of a US$400m expansion package planned for four US plants previously announced in November 2021. The upgrade work at Chowchilla will include the addition of a new furnace and other equipment that will use less natural gas and electricity. It is the largest investment in the site since its creation in 1978. Saint-Gobain Group estimates that these improvements will reduce CO₂ emissions by 4000t/yr at the site.

Ireland: Kingspan’s revenue rose by 12% year-on-year to Euro2.24bn in the first half of 2019 from Euro2.01bn in the same period in 2018. Its profit grew by 18% to Euro173m from Euro147m. Sales of its panel and boards products increased but panel sales growth was faster, supported by most territories with the exception of the Middle East.

“We have delivered a record first half with revenue growth in all our business units and a strong trading profit performance. We continue to expand our global production footprint with new facilities under construction in the US, Brazil and Sweden. The near-term outlook is solid although the political uncertainty in the UK, weakness in Serling, and weaker German economy are amongst risks we are monitoring closely,” said Gene Murtagh, the chief executive of Kingspan.

The building materials company is close to completing a new insulation panel plant at Modesto, California in the US. A new panel plant is also being considered in Pennsylvania, US and a new panel plant in Cambuí, Brazil is expected to be operational by the fourth quarter of 2019. A new board plant in Sweden is scheduled to start production in mid-2020.

US: Rockwool’s Comfortboard stone wool insulation product has been certified by the California State Fire Marshall’s Building Materials Listing (BML) Program. The product is resistant to fire up to 1175˚C and has a 0/0 Smoke Development and Flame Spread rating. The BML Program certifies products based upon an evaluation of test results that include an analysis of required product performance and reliability features. The testing was completed with a State Fire Marshall (SFM) accredited laboratory.

“This listing supports our continued commitment in the promotion of fire safe building practices and helps us deliver on products that will help architects and builders meet the California Title 24 thermal and Wildland Urban Interface (WUI) requirements,” said Mark Bromiley, Vice President of Marketing & Business Development, Rockwool (North America).

US: The Office of Environmental Health Hazard Assessment (OEHHA) in California has asserted that polystyrene is not the same as styrene and is not listed by the state as a substance that causes cancer. The OEHHA has added styrene to a list of a list of chemicals known to the state to cause cancer for purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).

"There is sufficient scientific information to demonstrate that the intended uses of these materials are safe,” said the OEHHA. "While free or unreacted styrene may be present in such products, only styrene exposures that pose a significant cancer risk would require a warning." Styrene is used to make expanded polystyrene (EPS) but the substances have different properties. The OEHHA's listing is based on the findings of the 12th edition of the National Toxicology Program's Report on Carcinogens that assesses the potential for risks associated with styrene, primarily in work environments where levels of styrene exposure may be higher.
