Specifier Sites

Architects, designers and other specifiers are welcome to use the Altherm, First and  Vantage Specifier’s Guides which are available in both print and digital format. Printed manuals can be requested through the ‘contact’ button (at left) and the digital manuals can be accessed through the specifier-oriented eboss website where the guides are maintained on the eboss library.  Inquirers will need to register and obtain a password to access the manuals.

They include technical data and CAD drawings for residential ranges, Metro Series, APL Architectural Series, Smartwood, Metro Thermal Heart and commercial window systems.
