The latest eco-project to which FAKRO has supplied roof windows is the Green Unit®, a modular, single storey Passivhaus design for a variety of sectors and the result of over three years development. The prefabricated buildings are carbon neutral, FAKRO FTP U5 non-vented, triple-glazed windows with a U-value of 0.97W/m2K having been used individually and in L-shaped configuration.
The L-shaped principle incorporates an additional lower window, in this case BDR tilt and turn, to take the glazing area into the wall. The FTP U5 windows have been installed in a green roof, those with an easterly aspect also having AMZ external awning blinds to offset solar gain.
The Green Units Jonathan Finnerty commented, The requirement to be carbon neutral meant that procurement for every element was considered in great depth. Fakro worked with us to achieve what we required and gave us highly valuable advice.
