Roof transition type GISOL are used e.g. in connection with roof hoods type VHL, VHA and VHP.
The combination provides a harmonious transition between roof penetration and hood. GISOL is built around two pipes with intermediate insulation of mineral wool and provided with end bottom at bottom.
By default, the outer tube is smooth. Spiral folded pipe SR as an alternative.
GISOL is delivered with roofing sheets in galvanized sheet or Wakaflex (stated when ordering).
GISOL must be attached to the rafters, use e.g. bar fittings type SBG / SBG1
