T30 RS Door: Fire Protection and Smoke Protection in One Element
In preventive building fire protection, specialized doors are indispensable. T30 RS doors are a particularly effective solution, as they provide protection against both fire and smoke—combined in a single certified building component. Understanding how these dual protective functions work is essential for planners, operators, and property owners to ensure comprehensive safety for people and assets
The Dual Protective Function Explained
A T30 RS door combines two critical protection features that play a decisive role during a fire:
T30 – Fire Protection The classification “T30” stands for fire-retardant. A T30 door, tested according to DIN 4102-5, must withstand fire for at least 30 minutes without losing its ability to act as a fire barrier. This significantly slows the spread of flames and heat, providing valuable time for evacuation and firefighting operations.
RS – Smoke Protection The designation “RS” stands for smoke-tight. This property is tested according to DIN 18095 and ensures that the door remains smoke-tight for a defined period under smoke exposure. In many fire scenarios, smoke poses a greater danger than flames due to toxicity, reduced visibility, and rapid spread. A smoke-tight door keeps escape routes clear and allows people to orient themselves.
The combination of these features makes T30 RS doors powerful elements in comprehensive fire protection concepts, addressing both the direct danger of fire and the often more hazardous threat posed by smoke.
Fields of Application and Their Importance
T30 RS doors are used across many types of buildings, especially where escape and rescue routes must be protected or where separating fire compartments requires dual protection:
Stairwells and corridors: Essential for maintaining smoke-free, fire-protected escape routes that serve as primary evacuation paths.
Access to technical rooms: In areas with potential fire loads—such as boiler rooms or electrical meter rooms—they prevent smoke and fire from spreading into adjacent spaces.
Connecting corridors: Between different parts of buildings or different uses, where both fire and smoke spread must be reliably prevented.
Key Considerations for Planning and Installation
A T30 RS door only achieves its full protective performance when it is properly planned, professionally installed, and regularly maintained. Important factors include:
Approvals and Test Certificates The doors must have valid general building authority approvals (abZ) or construction type approvals (aBG).
Correct Installation Critical installation details include: A maximum floor gap of 7 mm for smoke protection doors, continuous sealing around the door frame and ully functional closing mechanisms
Regular Inspection Like all fire protection systems, T30 RS doors are subject to mandatory inspections and must be regularly checked and maintained by qualified professionals to ensure long-term performance.
A T30 RS door is far more than just a door—it is a certified safety component that actively helps protect lives and minimize property damage in the event of a fire. Its integrated protective function makes it an intelligent and essential choice for modern fire protection concepts.
