Deforche Construct
Synergy of consultants, designers, makers
and builders of glass buildings

Thermoflor is a traditional Dutch family-run company with 120 years of experience in metal and glass structures. It started out as a greenhouse builder in 1900 and grew to become the market leader in the development and construction of turnkey ‘glass buildings’ and, in particular, garden centres. Since 2018, Thermoflor is a subsidiary of the Deforche Construction Group (DCG). Thermoflor works closely together with sister companies Deforche Construct and Forzon. Deforche Construct NV specialises in the design, production and construction of glass, steel and aluminium structures for agriculture and horticulture companies, garden centres, research facilities and industry in general. Forzon specialises in the production and installation of transparent roofing solutions. This company structure offers the three subsidiaries within DCG every opportunity to create synergy in the international market of garden centres and other glass buildings.
