Tradesmith choses Swisspacer spacer bars for top energy performance and good looks, the company has reported.
Managing director Mark Hutchinson said: “We want to ensure our windows have the best energy ratings so we buy sealed units with Swisspacer inside. Swisspacer is tried and tested to give outstanding energy efficiency and long-lasting results. Aesthetics are important and Swisspacer’s attractive, semi-matt finish and choice of colours are big advantages.”
