Specifier site


Architects, designers and other specifiers are welcome to use the First Specifier’s Guides which are available in both print and digital format. 

Our digital manuals can be accessed through the specifier-oriented Eboss website where the guides are maintained on the eboss library. Users will need to register and obtain a password to access the manuals.

The Eboss library contains a comprehensive resource of First windows and doors products. These include drawings, CAD files, specifications, quality assurance, compliance and environmental information, case studies, and technical advice. This includes detail for residential ranges, ThermalHeart Technology, Metro Series, APL Architectural Series, Smartwood, and commercial window systems.
