UK: Denmark-based Rockwool has acquired external thermal insulation composite systems producer Wetherby Building Systems. Reuters has reported that the newly acquired company will now operate as part of Rockwool Wall Systems, under the name Wetherby Wall Systems. The integration parallels that of previous Rockwool acquisitions in other markets, like Fast Wall Systems in Poland and Heck Wall Systems in Germany.

Rockwool CEO Jes Munk Hansen said “The share of stone wool insulation in the Wetherby business has been growing steadily, and we will be completing this transition to a fully stone wool-based portfolio, as we have done in other markets in the past.” He added that this will advance Rockwool’s transformation of the construction sector towards non-combustible façades.

Wetherby Building Systems managing director Bob Deane said “There is a long-standing relationship between Wetherby and Rockwool, and the match is strong on all significant drivers.”

Europe: Market research company Freedonia Group has forecast a 3% composite annual growth rate in European insulation demand over the five-year period between 2023 and 2028. This will result in a market value of €9.44bn, corresponding to volumes of 3.2Mt, in 2028. Drivers of the anticipated growth include tighter fire safety regulations and the cost effectiveness of mineral wool insulation.

Ireland: Kingspan says that its latest modifications to its GreenGuard GG300 insulation boards have further reduced their thermal conductivity to 0.033W/mK. Specification Online News has reported that the producer says that this will facilitate slimmer construction while still meeting U-values, especially important in high compressive strength-applications such as inverted roofs and flooring. Accordingly, the boards are now also available in a new, slimmer 180mm thickness. The entire range of GreenGuard GG300 boards integrates with Kingspan's BIM Designer software platform.

UAE: A researcher team at the United Arab Emirates University (UAEU) has developed a novel bio-polyester insulation based on polyhydroxybutyrate derived from date pits. The material has a thermal conductivity of below 0.1W/mK, with 80MPa compressive strength and 6 – 14MPa tensile strength. EurekAlert News has reported that the materials is also below 6% water absorbant.

Team leaders Amal Mlhem and Thomas Teklebrhan said that the bio-polyester insulation can lower the CO₂ emissions of commercial insulation and offer a biodegradable alternative.
