Local press has reported that the producer is in consultations with staff and unions, with 30 roles at risk, before taking any final decision.

Industrial Performance Director Darren Holt said "There is now excess manufacturing capacity for cured glass mineral wool insulation."

The Russian Far East and Arctic Development Corporation has reported that TechnoNICOL Far East plans to invest €2.33m in the Khabarovsk insulation plant in 2026, down slightly from €2.55m in 2025.

Plant Director Nikita Yakovlev said "Part of the 2026 investments will be used to improve product quality, reduce costs and implement environmental initiatives. The company will also develop its own IT infrastructure and continue projects to improve labour safety and working conditions."
