Kingspan has announced that the Divisional Managing Director of its insulation board business is to retire at the end of the year.
Peter Wilson is also to step down from the board of Co Cavan-based Kingspan Group.
"Mr Wilson's decision to retire reflects his view that now is the right time to hand over to new leadership at an important time for the Insulation Boards Division," Kingspan said in a statement.
"The board thanks Peter for his contribution," it added.
The company also announced that Alan Lawlor will replace Mr Lawlor as head of its insulation boards business.
He is currently the chief financial officer of that part of the group and Managing Director of Kingspan Insulation, Southern Europe.
The company is also creating a new role of Group Head of Compliance and Certification.
The position, reporting to the group chief executive Gene Murtagh, will be filled by Jim Carolan, who was operations director in the company's insulated panel's division.
"In this newly created role he will be responsible for ensuring a rigorous approach to certification, testing and product compliance across all Group divisions," the company said.
The announcements come after recent appearances by Kingspan's employees and former employees as witnesses at the Grenfell Tower Inquiry in London.
A small amount of Kingspan's Kooltherm K15 insulation product was used in the tower block which was destroyed in an inferno that killed 72 people in June 2017.
Kingspan's insulation product made up 5.2% of the insulation used on the building's facade.
The inquiry has been postponed until January 11 as one of the members tested positive for Covid-19 earlier this month.
