Insulation industry news from Global Insulation

Netherlands: Nine-month restated sales for Recitel fell by 7.3% year-on-year to Euro924m in September 2019 compared to Euro997m in the corresponding period of 2018. Despite ‘double-digit’ volume growth, insulation sales over the period fell by 4.5% to Euro193m from Euro202m due to pricing issues stemming from the loss of market share to fibre insulation as a lingering after-effect of the isocyanate shortage of 2017. The company noted the ‘ramping-up’ of production at its new plant in Finland, with all products now certified for sale in the Nordic countries. Recticel CEO Olivier Chapelle noted the continued substantial decrease in debt as a positive in the period.

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: Owens Corning plans to expand its RainBarrier continuous insulation product range. The new products in the portfolio will offer better compressive strength. They will be available in the second half of 2019. The building materials producer made the announcement at the AIA Conference on Architecture.

US: Owens Corning has received R-value certification across all its fibreglass and mineral wool batts and rolls sold in the US. This validation was awarded from the North American Insulation Manufacturers Association (NAIMA) following testing and validation by an accredited third-party laboratory.

Under the program, Owens Corning agreed to have a random selection of products regularly tested to verify compliance with the thermal performance requirements of the Federal Trade Commission's (FTC) ‘Labeling and Advertising of Home Insulation’ (16 CFR Part 460) regulation.

The R-value certification represents the latest in third-party verification Owens Corning has earned across its insulation product portfolio. It will be visible on its packaging later in 2019.

China/Germany/US: The Mannheim Court in Germany has found that Chinese companies Guangdong Alison Hi-Tech and Nano Tech infringed one of Aspen Aerogels’ European patents by selling infringing aerogel insulation products. As part of the judgments, the Mannheim Court issued injunctions prohibiting the offer, distribution, use or import of infringing products in Germany and held Nano and Alison liable to Aspen Aerogels for damages, court costs and some of Aspen's legal fees and expenses. The Mannheim Court's decision is subject to an appeal to the Higher Regional Court of Karlsruhe. In a related lawsuit, the Mannheim Court had previously issued a series of judgments against Hiltex Techniche Weefsels, a Dutch reseller of the infringing Chinese aerogels.

In addition, the German Federal Patent Court in Munich found the Aspen patent to be valid as granted in a patent nullity action initiated by Nano. The Munich Court's decision follows other unsuccessful challenges to the validity of Aspen's patents by Nano and Alison in the US and China.

"Our core strategy is to invest in the research, development, commercialisation and protection of our aerogel technology platform worldwide. These European patent wins, along with our 2018 victory at the US International Trade Commission, reinforce the scope and strength of Aspen's patent portfolio," said Don Young, President and chief executive officer (CEO) of Aspen Aerogels.

UK: Knauf Insulation’s Earthwool RainScreen Slab product has been certified by the British Board of Agrément (BBA) for use in high-rise residential applications. The BBA certification follows the December 2018 update to Approved Document B, which mandates the use of non-combustible materials achieving a Euroclass Reaction to Fire Classification of A1 or A2 s1-d0 in the external walls of certain buildings over 18m in height.

“Non-combustible insulation is the best choice for architects, specifiers and contractors as it will not contribute to the development or spread of fire” said Steve Smith, Head of Product Management and Business Intelligence at Knauf Insulation.

Australia: Kingspan Insulation is preparing to discontinue its Kooltherm K10 FM Soffit Board rigid insulation product ahead of changes to the National Construction Code (NCC) set to be enforced on 1 May 2019. The standard introduced in 2016, AS 5637, requires foil faced internal lining materials to be installed on both walls and ceiling when undertaking the full-scale room fire test ISO 9705.

To prepare for the change Kingspan will promote its Kooltherm K10 FM G2 Soffit Board product. It features a thicker foil lining and has already undergone the ISO 9705 test, achieving a Group 2 rating. The product has been supplied to the New Zealand market and it will now be launched in Australia.

“Kingspan Insulation have been preparing for this transition for some time. We are confident in our ability to supply a product that will not only adhere to the new NCC standard but will also provide the same great thermal performance that our customers have come to expect from us,” said Kingspan Insulation’s Sales Director, Craig Burr.

Germany: Evonik’s Calostat insulation product has received an environmental product declaration (EPD) from the Institut für Bauen und Umwelt (IBU). The EPD takes into account the entire production process, from manufacture of precursors, their transport, production of Calostat and the option of recycling the material.

Calostat is a non-combustible thermal insulation material based on silicon dioxide.

It is a class A (non-combustible) building material with a thermal conductivity λ of 0.019 W/(mK). It does not absorb liquid water but is permeable to water vapour. Other distinguishing features are its compressive strength of ≥ 90 kPa and gross density of 165kg/m³. It contains no fungicides, algicides, pesticides, binding agents, or flame-retardants. Notably, the manufacturer also says that the product can be recycled.

US: Thermoseal has launched three new spray foam insulation products: Thermoseal 360, Thermoseal 800 and Thermoseal One. Thermoseal 360 is an ultra-high yield open cell spray foam insulation. Thermoseal 800 is a new ultra-high R-value open cell spray foam. Thermoseal One is an ultra-high yield, ultra high R-value, one pass, closed cell spray foam insulation. Thermoseal One has also passed the Hurricane Wind Uplift test, which means it is approved for use in Hurricane zones across the US.

Thermoseal manufactures polyurethane spray foam insulation, roofing, and other similar products for the residential, commercial and industrial construction industry.

Belgium: Recticel is promoting its Du.Panel X polyurethane panel product for the agricultural sector. It offers a lambda value of 0.020W/mK for panel thicknesses of 40 – 120mm and fire resistance with Euroclass B-s2,d0. The product is intended for using in livestock buildings and stables. It joins other agricultural products including Powerline, Cronus and Eurothane.
