Natural ventilation:
fire resistant grills
The fire resistant grills represent the ideal solution for:
•t The natural ventilation of adjacent fire resistant compartments: grill built into a fire-resistant door or wall.
This solution is recommended in hospitals or office buildings, for example. The grill finishing must retain
the aesthetic qualities of the premises and the intimacy of each compartment.

•t The natural ventilation of technical premises: grill built into fire-resistant walls or doors.
The level of fire resistance and the dimensions of the grill take precedence over aesthetic qualities.

A
range of certified solutions
The fire resistant transfer grills are mounted in the walls or the doors to prevent flame and heat
propagation in the event of a fire. Situated at the interface between the worlds of ventilation and
passive fire protection, these grills must respond to the needs and regulatory standards inherent
to these two domains.
According to European legislation concerning the fire resistance of construction products, the fire resistant grills
are destined for the natural ventilation of premises and cannot be used for mechanical ventilation applications.
Specifically, this means that a fire-resistant grill cannot, for example, be installed into a mechanical ventilation
shaft. In this situation, only a fire damper would respond to requirements such as environmental pressure.
A compliant range for all types of walls: Rf-Technologies offers a wide range of fire resistant
grills that meet the strictest European standards regarding the penetration of fire resistant
walls, floors, ceilings, and doors.
The fire resistant grills do not constitute an adequate solution for preventing the dispersion of smoke and cold
gases as the functioning of the grill is heat-activated.

Fire resistance: Rf-Technologies grills are made of profiles in synthetic material filled with
intumescent strips that inflate in the event of fire in order to rapidly seal the opening and offer
protection against flame and heat propagation during a guaranteed lapse of time.
Optimal air circulation: Rf-Technologies grills are conceived to allow superior natural
ventilation. The range is also characterized by the availability of an aesthetic model and by a
wide choice of dimensions: up to 1200 mm x 800 mm.
