In a fire, toxic smoke is the leading cause of death. The smoke also causes the most damage and nuisance in the entire building.
That is why we recommend that you also integrate smoke tightness into your doors, windows and gates, even though there is no obligation to do so in most countries.
Smoke density can be added as a performance to almost all doors, gates and windows supplied by us.
