Lamont Holdings, the Belfast-based textiles group, has agreed to sell its carpet underlay business and related assets to Duralay for £2.15 million sterling. It sold its Shaw carpet business last December. Lamont said its latest sale will "improve the focus of the carpet and carpet yarns division on areas of competitive advantage". The proceeds are to be used to reduced borrowings. There will be a capital profit on the sale as the value of the book assets amounts to £0.38 million.
