The type B1 lightweight roof bases are suitable for round
ductwork systems. The standard version is made from
galvanized steel sheet and designed for flat roofs. The top
part of the roof base comes with a FLS steel flange in the
standard version. The roof base is available on request with a
male connector or a connector provided with an EPDM rubber
gasket. Other versions available on request include roof bases
designed for sloping roofs or made from stainless steel sheet
or aluminium sheet. The roof base is a perfect match for roof
intakes, roof exhaust vents, and roof ventilators (fans).
