The THM90 EVO is a flush aluminium thermally broken flapvent for installation in aluminium, timber and uPVC window frames and ideal for sliding doors. The flat punched internal profile serves as an insect mesh and can easily be cleaned.
The internal flap can be set in 5 stepped positions (open/closed + 3 intermediate). A self-regulating (class P3) flap is integrated within the closing flap preventing draughts and guaranteeing watertightness up to 20 Pa in open position.
