Thermoseal Group, the UK’s leading manufacturer of warm edge spacer systems and distributor of over 2,500 insulated glass (IG) components, has been named ‘Spacer Bar Manufacturer of the Year’ in the National Fenestration Awards for the second time. The National Fenestration Awards are the industry’s fastest growing independent awards which are run and decided completely by the participation of the industry. At the start of each year, there is a nominations phase where anyone can put forward the names of people and companies in over two dozen categories who they believe deserve to be recognised. The industry then votes on a shortlist in each category based on the nominations submitted.
