Insulation industry news from Global Insulation

Germany: The Fraunhofer Institute for Environmental, Safety, and Energy Technology in Oberhausen is reportedly looking for partnerships through which to commercialise its new aerogel-based insulation. WAZ Plus News has reported that the insulation consists of porous beads made of 99% air.

Materials from the Fraunhofer Institute’s pilot plant have featured in construction projects including in the historic Hanseatic Quarter of Lübeck, Schleswig-Holstein, and the town hall of Hohen Neundorf in Brandenburg.

Sweden: Svenska Aerogel says that it has received an order for 360kg of its Quartzene silica aerogel from a Europe-based insulation producer. Quartzene is the brand name for various synthetic silica powder materials produced by Svenska Aerogel.

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.

Germany: Dennert Poraver has developed an insulating render formulation by using Poraver expanded glass aerogel granules from Cabot in 0.01 - 4mm sizes. The expanded glass granules producer says that aerogel thermal insulation renders are ultra-light, water-repellent, open to diffusion and achieve high thermal insulation even with small layer thicknesses.

The new product is targeted for the interior and exterior renovation of historic buildings. Due to the thin application layer, the producer says that the characteristics of the building remain largely unchanged. The building material can also be used for rendering masonry in new buildings. The insulating renders are also classified as ‘non-combustible, smoke-development free, non dripping.’ This means that they can also be used for facades, where previously only mineral wool-based insulating materials could be used due to increased fire protection requirements.

Poraver and Aerogel were combined for the development of a mineral thermal insulation render in order to combine the advantages of both lightweight aggregates. Cabot Aerogel supplied aerogel in the form of 0.01 - 4mm granules for the insulation render. Poraver was added to the render as a mineral aggregate with a grain size of 1 - 2mm. Various proportions of aerogel and Poraver were tested. After the tests, it could be determined that the compressive strength and processing properties had improved ‘significantly’ with the addition of Poraver. The most economical and practicable formulation has a thermal conductivity of 0.037W/mK with a dry bulk density of 199 kg/m³.

US: Aspen Aerogels has won an initial determination US International Trade Commission (ITC) against Alison Hi-Tech and Nano Tech with regard to patents related to aerogel insulation. Administrative Law Judge McNamara found that Alison Hi-Tech and Nano Tech had infringed against three patents. McNamara also recommended a limited exclusion order as a remedy to prevent the importation of infringing aerogel products into the US. A final determination on the violation and remedy is expected from the full ITC commission by 29 January 2018.

Germany: HASIT Trockenmörtel GmbH's Fixit 222 Aerogel product, a Cabot Aeorgel-containing insulating plaster material, was recently recognised as one of the most innovative products exhibited at the BAU 2015, a trade fair for architecture, construction materials and systems.

"We are seeing a rise in interest in insulative aerogel coatings and plasters due to increased focus on environmental, energy-efficiency and safety requirements," said Milto Vlachos, general manager of Cabot Aerogel. "We believe that our Aerogel can help customers to reduce energy costs and lower carbon footprints in buildings around the world. Through our technical collaboration with HASIT, we have developed a product that helps customers apply insulation on all types of buildings, including historic façades. It also delivers superior performance compared to similar products on the market today."

The HASIT Fixit 222 Aerogel was recognised for the role that the material can play in reducing the energy consumption of buildings. The material, which is a combination of Cabot's highly-insulating Aerogel and hydraulic lime plaster, has a low thermal conductivity that provides insulation three to four times more effective than conventional insulating plaster. The material meets fire safety and flammability requirements without using environmentally-hazardous flame retardants. It can be prepared and applied manually or with conventional application machines for both indoor and outdoor areas.

Fixit 222 Aerogel can be used for façades worth preserving or with historic building status. The material allows planners, architects and builders the aesthetic and performance advantages of mineral plaster, while setting new standards for both internal and external insulation. It has been used in the Swiss market since 2013 and HASIT began selling Fixit 222 to the German markets in 2014.
