A doors and windows manufacturer is to create 225 jobs in the North over the next three years.
The Camden Group, which is making a £16m investment, is one of the UK and Republic of Ireland`s largest manufacturers of PVC doors and windows.
Managing director Kieran Lavery said: "This investment is part of our strategy to double the level of sales outside Northern Ireland. The support offered from Invest NI will play a vital role in helping us to achieve this."
Invest NI has offered more than £1.6m, part funded from Europe.
Mr Lavery added: "We have identified significant opportunities in the GB new build housing market, particularly in south east England. The benefits gained from this project will place us in a strong and competitive position to win new business."
A new window design will include recycled material.
Enterprise Minister Arlene Foster said: "The project will create 225 new jobs generating wages and salaries in excess of £4m annually, which is welcome news for the local community and wider economy.
"Camden is among the many Northern Ireland companies that are focusing on new product and process innovation to enhance business performance. With support from Invest NI, Camden will streamline its manufacturing process and be best placed to gain new business."
