The group behind the successful SuperFOIL Insulation brand say annual sales are up almost a third.
Management at Boulder Developments, which also owns airflow specialist Ventilation Megastore and cork tiling supplier Treefloor, said turnover topped £9.5 million last year, 30 per cent up on the previous year.
The Lincoln-based group – which was established by Craig and Alison Bown in December 1997 and today employs 46 people – said growth was driven by demand for its “cost effective, high performance” insulation as families work to keep high heating bills down.
