Insulation industry news from Global Insulation

UK/Ireland: Knauf Insulation UK & Ireland has launched ‘OmniFit Slab 32’, a 32 lambda glass mineral wool insulation slab product for use in light steel frame systems (SFS) as part of a rainscreen façade or other external wall build-ups.

Liliya Luke, the Glass Mineral Wool Product Manager at Knauf Insulation, said “We have launched OmniFit Slab 32 to help our customers deliver the low U-values required, without compromising on fire safety, acoustic performance or sustainability.” He added, “Specifiers can now optimise their rainscreen façade systems by adding the benefits of glass mineral wool to their build-up - delivering acoustic performance, and reduced embodied carbon compared to rock-only solutions, with an insulation specification that remains completely non-combustible.”

The new product is primarily designed for use with ‘Rocksilk RainScreen Slab’ when used in rainscreen applications, and is suitable for use in the external wall systems of all residential buildings over 11m tall and relevant residential buildings over 18m tall. It is the latest addition to Knauf Insulation's OmniFit range of glass mineral wool roll and slab products.

US: Owens Corning has published plans for a new extruded polystyrene (XPS) insulation plant in Russellville, Arkansas. The Courier newspaper has reported that the plant will produce the company's Foamular NGX brand insulation. It will employ an estimated 50 people.

Owens Corning previously invested US$24.5m in an expansion to its Fort Smith glass and mineral wool insulation plant in the state, also creating 50 new jobs.

Denmark: Rockwool’s net sales grew by 27% year-on-year to Euro3.91bn in 2022 from Euro3.09bn in 2021. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 6% to Euro638m from Euro602m. The group reported a strong start to 2022 with high demand for its stone wool insulation products. In the second half of the year it noted a decline in construction activity in key markets. However, it increased its prices leading to increased sales. By region the group said that sales grew in Europe and Asian markets, were flat in the US and declined in China.

Chief executive officer Jens Birgersson said, “Looking forward, we expect construction activity to continue slowing down in the coming period. We anticipate the energy efficiency agenda in both Europe and North America will accelerate renovation rates in the mid-term and create higher demand for our circular and non-combustible stone wool. We will continue to invest in more capacity to support our long-term growth”.

Together with the group’s chair Thomas Kähler, he also defended the company’s decision to continue the ownership of a subsidiary in Russia. “If we were to depart Russia, our factories and the intellectual property rights to our unique technology would most likely be nationalised or otherwise transferred to local players. Since the factories operate independently of our head office, they would continue to operate - just under different ownership. It therefore remains our view that retaining the business in Russia is the least bad option available to us. And of course, we will continue to comply with all international sanctions.”

Rockwool said that it had added production capacity for its Grodan agricultural stone wool range at its plant in Toronto, Canada and capacity for its Rockfon stone wool ceiling panel range at its Cigacice plant in Poland. In China it had opened a new plant at Qinyuan in December 2022 to replace its mineral wool unit at Guangzhou, which closed in September 2022. It also reported that plans to build a new stone wool plant at Soissons in France had been delayed due to a local legal challenge. Notable upgrades in 2022 included the start of a conversion project to electric melting technology from fossil fuels at the Flumroc plant in Switzerland, with a commissioning date scheduled for 2024. This project follows a similar one at the Moss plant in Norway that was completed in 2020.

UK/Ireland: Knauf Insulation has appointed Ross Foreman as its National Wood Wool Manager for UK & Ireland. Foreman will support the company’s drive to meet increasing demand for its Heraklith range of wood wool products.

Knauf Insulation offers two core products in the Heraklith range: the Heraklith A2 Decorative Panel, which is a cement-bonded wood wool panel; and the Heraklith Tektalan A2 SmartTec, which is a cement-bonded wood wool panel combined with a rock mineral wool insulation core. Both products are non-combustible with A2 - s1, d0 Euroclass reaction to fire classification.

The Heraklith A2 Decorative Panel is designed for use in residential, recreational, industrial and commercial environments where sound absorption is desired. It is available in three panel thicknesses with thermal conductivity of 0.085W/mK.

Heraklith Tektalan A2 SmartTec is suitable for insulating the soffits of carparks and underground garages, basement ceilings and technical rooms. It has a thermal conductivity of 0.095W/mK and the mineral wool core a thermal conductivity of 0.034W/mK.

Belgium: Recticel’s Simfocor polyurethane board product has been certified a ‘Solar Impulse Efficient Solution’ by the Solar Impulse Foundation. The label is awarded to products, services or processes combining credible environmental and economic performance. It also means that Simfocor joins the Solar Impulse Foundation’s list of products selected for their contribution to clean economic growth.

Simfocor is part of the ‘Recticel Silence’ insulation range and is currently sold in France and Spain. It is a polyurethane insulation board that is marketed for both its acoustic and thermal insulation properties. The product is made of recycled polyurethane foams sourced from discarded mattresses.

Ireland/UK: Kingspan has launched a range of reduced-CO₂ insulation panels called QuadCore LEC. The producer says that a 100mm-thick QuadCore AWP panel has 40% lower embodied CO₂ than an EN15804-A2 standard insulation panel of the same thickness.

Kingspan’s head of innovation Mike Stenson said “As a business we are committed to developing high performing, energy efficient building envelope solutions that help minimise the carbon footprint of buildings over the whole life cycle.” He added “QuadCore is already one of the highest performing insulation technologies in terms of thermal efficiency (underpinned by a 25-year thermal warranty), which could enable higher energy and carbon savings through the operational life of the building. This is the first step on our journey to reducing the embodied carbon of our products, and we anticipate some major milestones by 2030 to drive that down even further.”

Europe: Dow has announced the European launch of V PLUS Perform Next, a polyurethane (PU) insulation product for use in insulated metal panels. V PLUS Perform Next insulation contains alternative raw materials from circular feedstocks, including bio-based feedstocks. Dow allocates the feedstocks based on a mass balance chain of custody, validated by International Sustainability and Carbon Certification (ISCC). It produces V PLUS Perform Next using over 25% renewable energy.

Dow PU construction insulation marketing fellow Alberto Mercati said “The new EU Energy Performance of Buildings directive adds urgency for buildings that require energy efficient insulation with decreased embodied carbon. For the last five years, V PLUS Perform has enabled insulated metal panel manufacturers to deliver building envelopes that couple energy efficiency and fire safety. V PLUS Perform Next supports insulated panel manufacturers to select lower carbon and circular construction ingredients from the design phase to the delivery of a novel class of products for more sustainable buildings.”

UK: Denmark-based Rockwool has launched its NyRock stone wool technology in the UK. The insulation producer says that the new product offers the “lowest lambda stone wool insulation available in the UK.” It is manufactured using a new patented production process and offers a thermal conductivity as low as 0.032W/mK. One of its key features is that it can deliver better insulation with comparatively thinner constructions compared to similar products. It also offers the usual benefits of stone wool insulation including durability, recyclability, acoustic properties and fire resistance. NyRock technology will be rolled out across a range of Rockwool insulation products during 2022.

Denmark: Tentoma has launched its new XL Power insulation panel packing machine. The supplier says that machine can pack up to 19m-long panels. At shorter lengths, it can stretch film for more panels per packaging cycle, increasing the packaging speed for the products by up to 25%. Tentoma built and sold its first XL Power packiaging machine to replace an orbital wrapper.

Belgium: Recticel Insulation has obtained Programme for the Endorsement of Forest Certification (PEFC) for its multilayer thermal insulation products. It says that it is the first polyisocyanurate (PIR) and polyurethane (PUR) producer to do so. The insulation manufacturer will be selling thermal insulation products, with multilayer paper facings made from wood fibres sourced from a PEFC-certified and sustainably managed forests. The PEFC label will be added to its Recticel Eurowall, Eurothane Silver, Eurothane Silver A, Eurofloor, Euroroof, Eurothane GP, Eurowall Cavity and Eurothane Eurodeck products.

Recticel Insulation already held the PEFC label for some of its insulation products manufactured at its plants in Bourges, France and Stoke-on-Trent, UK. The certification is now being gradually rolled out to more products and to all plants where multilayer facings are used.
