The owner of Guardian Glass has requested to close its two Russian float glass manufacturing facilities.

Dave Robertson, President of Koch Industries, the owner of Guardian Glass said: “Sanctions announced in early April combined with the Russian government’s response and other actions, have made conditions untenable for Guardian to continue operations in Russia.

“As a result, Guardian asked its Russian employees to shut down the two glass plants.

“When made aware of this plan, Russian authorities repeated earlier warnings that local Guardian employees would violate Russian law and be prosecuted and imprisoned if they followed through with any shutdown activities, further reinforcing our concerns for employees’ safety.

“Therefore, Guardian is working with its local management team to find an exit strategy that maintains our commitment to employees’ safety and does not result in the Russian government taking over the plants and financially benefiting from them.

"As a company and as individuals, we have consistently condemned Russia’s action and remain united in support of all employees and others who are harmed by this terrible war."
