RHTG roof hatches are fitted with a monolithic pane of safety glass. This ensures maximum light transmission and optimum thermal insulation.
The glass pane is also impact and burglary resistant. HR+++ insulating glass is used to make the climate in the space below even more pleasant, which brings the insulating value of the cover to U ≤ 0,500 W/(m².K). The glass is self-cleaning due to the pitch of the roof hatch. All glazed roof hatches are fitted as standard with two powerful electric motors operated electrically.
