Insulation industry news from Global Insulation

Germany: 7116 hectares of construction hemp are under cultivation in Germany in the growing season for 2025. This represents a 22% year-on-year rise in the total area since the 2024 harvest. Brandenburg has the greatest acreage of any state, with 1500 hectares (21%).

Brandenburg-based Felde Fibres is investing ‘tens of millions’ of Euros in current capital expenditure in its production of hemp for the building materials and textile sectors.

Local press has reported that hemp demand continues on a long-term growth trajectory, despite nearly doubling in prices since the beginning of the on-going energy crisis in 2022.

UK: Indinature has secured approval for the use of its IndiBreathe hemp insulation in two UK Office of Gas and Electricity Markets (Ofgem) home insulation schemes. IndiBreathe will be the first natural fibre insulation used in such a scheme in the UK when it debuts in the Great British Insulation Scheme (GBIS) and Energy Company Obligation 4 (ECO4) initiatives. Construction Index News has reported that utilities provider Scottish Power sponsored Indinature’s application for the approval.

Sales Director Brian Monaghan said "Contractors can now specify a natural, sustainable and healthy high-performance insulation product when installing loft insulation under the government schemes."

UK: Wull Technologies has secured funding to scale production of its LAMDA sheep’s wool-based insulation panels. The company will produce the panels at its Manchester plant, using wool from sheep in Wales. Farming UK News has reported that the insulation is both recyclable and biodegradable. It matches the thermal and acoustic performance of mineral wool, but with increased moisture management ability.

The University of Manchester's Innovation Factory and the Greater Manchester Combined Authority supplies the latest funding, bringing the total received by the company to €597,000.

Technical Director Liam Britnell said "We set out to use materials science to open up new markets for this abundant and underutilised material. Rigid panel insulation is widely used and preferred across the construction sector because it is easy to handle, install and cut to shape."

Ukraine: Horticulture company Green Wave Organic has developed a new peat-based substrate to replace mineral wool in vertical horticulture at its facilities in Zolochiv, Lviv Oblast. New Voices of Ukraine News has reported that Green Wave Organic recently received a €15,000 EU4Business grant from the EU.

Compliance officer Ivan Fryz emphasised the need to continue to innovate under challenging circumstances, with electricity prices double their April 2024 levels.

Iraq: Researchers found that a sawdust-clay composite reduced power consumption for cooling by up to 37% when used as insulation in test rooms in Kirkuk. In a paper published in the Scientific Reports journal, the team recorded a thermal conductivity of the material of 0.44W/mK. It noted the suitability of the material as a circular insulation alternative for construction in arid regions.

Germany: The Central German Architects' Day took place in Apolda, Thuringia, in October 2024. The event included in-depth discussions on possible uses of regionally available alternative raw materials in insulation production. Stern Online News has reported that avenues for exploration include a novel load-bearing straw-based insulation developed at the Bauhaus University Weimar in Thuringia.

Germany: Researchers at the Fraunhofer Institute for Applied Polymer Research have developed a novel insulation from fungal mycelium. Professional Engineering News has reported that the materials are naturally woven by the mycelium filaments by which fungi spread. Researchers successfully varied fungus type, feed and environmental conditions to produce a range of performance characteristics comparable to conventional expanded polystyrene (EPS) and extruded polystyrene (XPS) insulation. Additionally, the materials offer high fire resistance and moisture regulation.

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.

Denmark: Architecture and engineering consultancy firm Ramboll has published a new study into the possible reduction in CO2 emissions offered by wood-based construction. The study quantified the total reduction potential at 12 – 39%. Materials included in the study included wood fibre or paper insulation, alongside structural timber and wood cladding. Ramboll analysed six types of buildings, including multi-storey and single-family houses.

Austria: Strabag has acquired hemp insulation producer Naporo Klima Dammstoff from Synthesa. SeeNews has reported that Strabag expects the acquisition to help it to expand its product range in line with its 2040 decarbonisation target. Meanwhile, Naporo Klima Dammstoff says that it will work with Strabag to explore new applications for its products, including in green roofs and as acoustic insulation.

Synthesa managing director Georg Bluemel said “In Strabag, we have found a partner who will continue to write Naporo’s success story in the future. We look forward to additional growth prospects for the company and its employees.”
