Smoke curtains, smoke barriers

The primary goal of fire and smoke-resistant doors and windows is to protect lives, and their design, selection, installation, and maintenance require great responsibility. Therefore, fire- and smoke-resistant doors, as well as their manufacturing, must meet the requirements specified by various standards and regulations, and this compliance must be verified. In addition to these requirements, aesthetic and practical considerations can also be taken into account.

Coolfire Ltd.’s expertise, the suitability of its products, and their reliability are supported by:

Pioneers in introducing aluminum-framed fire- and smoke-resistant doors in the domestic market
Experience gained over more than 15 years in the market
The use of fire-resistant doors in numerous buildings, with trouble-free operation, durability, and maintenance

The greatest achievement in the fire protection sector of the construction industry in recent years is the introduction of fire and smoke-resistant curtain families, providing new opportunities in the design phase of buildings.

Large fire and smoke compartment walls can be replaced with automatic smoke-resistant curtains, increasing the interior space thanks to the curtain’s open state. They only close in the event of a fire.

Their small space requirements allow for installation above suspended ceilings in a hidden form, preserving the visual appearance of the interior spaces.

An economical solution.

Special custom solutions, properties:

The Coolfire smoke curtains (Classification requirements DA, DH) come in a wide range of colors, providing solutions for most installation situations, meeting both technical and aesthetic requirements.

The fixed, suspended, tensioned smoke curtain, with its quick installation and cost-effectiveness, can replace drywall or other types of curtains, is durable, requires no surface treatment, and, due to its light weight, does not require a separate supporting structure.
In case of space limitations, automatic smoke curtains can ensure, for example, the unhindered operation of forklifts or conceal the smoke curtain for aesthetic reasons.
Can be used on escape routes.
The Z-type smoke control automatic curtain opens with its sides folded in a harmonica shape, and in the open state, it collects in the ceiling box installed above the suspended ceiling, seamlessly blending with the lower plane of the suspended ceiling. It is suitable for forming a right-angled, U-shaped, or regular quadrilateral enclosed shape with 2, 3, or 4 contiguous sides.
The horizontally designed curtains allow for ceiling penetrations, preserving the advantages of open ceilings.

The Coolfire fire-rated smoke and smoke control curtain family types have Sa smoke control properties. More detailed descriptions of the structures can be found on the Fire-Rated Curtains product page.

Application Area

The possibility of creating large-area curtains and the ability to hide the ceiling box containing the components required for the curtain’s opening (rolling up) – such as the axle and tube motor – in the suspended ceiling space makes it suitable for use in all types of buildings where fire and smoke spread needs to be prevented.

Exceptions include:

The smoke control curtains and automatic smoke curtains are not doors!

According to the tests based on MSZ EN 1191:2013, MSZ EN 14600:2005, MSZ EN 4102-18:1991, their self-closing ability is C1 (1,000,000 opening-closing cycles), with mechanical stability and operational reliability classified as C1.

They can be used for fire-related closures, and in their default state, the curtain is always in the rolled-up position.

Appearance

The curtain is made of fiberglass material, reinforced with stainless steel braid, and is fixed to a 78 mm diameter axle. The entire system is driven by one or more 24 V tube motors, depending on the size, and its operation is ensured by a control system. The operator panel requires a 230 V input and 24 V output voltage. An uninterruptible power supply (UPS system) ensures the connection with the fire alarm panel and curtain operation using the emergency release buttons for up to 6 hours during a power outage. According to regulations, emergency release buttons must be placed on both sides of the curtain or smoke control curtain that closes to the floor.

Its components, roof box cover, 120 mm wide vertical guide rails, and lower stiffening rod are made of galvanized steel, with an optional RAL color coating.

The roof box can be fixed to the ceiling or beam from below, using steel brackets, or to the beam from the side.

The size of the roof box varies depending on the structure’s height.

The width of the structure can be increased by overlapping the curtain material, in which case two parallel tube motors built into two sets of axles perform the opening. Depending on the available space, the axles can be used side by side or stacked on top of each other.

In the event of a power failure or fire signal, the closure happens gravitationally.

Suitable wall structures / building construction

Only the types specified in the permit, based on measurement results, are allowed for the installation of fire-resistant structures.

The Coolfire Smoke DA, DH type smoke curtains can be installed on:

Concrete or brick walls, beams
Steel load-bearing structures with fire-resistant cladding/paint coatings

There is also the possibility of using other, custom reception or load-bearing structures; in this case, the technical and fire safety compliance must be confirmed with a specific statement.

For each application, the design of the load-bearing steel structure must be verified through structural calculations.

Installation options:

Fixed to the opening plane, requiring a concrete beam
Fixed from below to a concrete ceiling
The fixed smoke curtain can be installed on a trapezoidal metal ceiling
Suspended from a ceiling using steel brackets
On the plane of a steel load-bearing structure
On drywall and sandwich panel walls, with the opening reinforced by a steel load-bearing structure
