Our Expertise
Thermosash’s abilities have grown since its 1973 start-up when Laurie Hayes and his colleagues manufactured commercial windows out of a small production facility. It quickly became apparent that the products and skills of the workforce were creating a performing quality, flexible product that the market sought.

Over time, our teams of dedicated and committed people have grown, this has been possible through constant reassessment of internal and external processes and manufacturing methods from around the world. We’ve also provided ongoing reinvestment in the training of our people to ensure lean process, IT Systems, material handling machinery and transport logistics equipment, as well as design office and factory production process improvements. We are able to offer a world class company with manufacturing facilities in Auckland, Wellington and Christchurch.
