Frequently Asked Questions

Yes, tests have been carried out in Sandwich panels of 100 mm with rock wool filling, results were obtained up to 120 minutes with this. For more details, please consult the Multiselector or contact us.

Yes, our support team will help you find a fitting solution. Before proceeding with installation, it should first be submitted to the proper authorities for authorization. Request your advice via: [email protected]

Each product has its own area of application. In the case of Multisealant GR, elastomer insulation can be fireproofed up to a thickness of 43 mm with Multisealant GR. The maximum thickness of the insulation in combination with Multisealant GR always depends on the diameter of the pipe, the requirement and the construction behind. Consult the Multiselector for the correct application.

No, intumescent products in particular should be irradiated by fire at all times. Only then can they react in time and seal the cavity against passage of hot gases, smoke and flames. In the case of wood-wool cement boards, we recommend expanding the fire protection openings locally with the Multimatic C system.

No, this should not be assumed as standard. Shaft walls often have a different construction (2x12.5 mm or 2x15 mm plaster on MS profile). Consult the Multiselector for the correct finish. Is it not listed? Then get advice from our support team via: [email protected].

Yes, this is allowed. According to Exap/EN 15882-2, a brand of stone wool other than that tested may be used provided it meets the same thickness and density as the tested batt and has an ablative coating (non-foaming). This was previously already applicable to fire-resistant mortars.

Omdat isolatie rondom leidingen een bepaalde functie heeft, raden wij aan deze niet te verwijderen tenzij anders aangegeven. Via de Multiselector zijn alle oplossingen te vinden waarbij onze producten rondom de isolatie zijn getest.

In many cases, this is possible with a water-based paint system. Please refer to the Technical Data Sheets (TDSs) on our download page for more information. If you do have any questions please contact our support team at: [email protected].

The Multicollar Slim is tested in various configurations, including different sockets. For example, the electrofusion coupler and various adhesive and sliding sockets. All tested configurations can be found in the multi-selector.

This depends on the surface on which the Multicollar Slim is mounted. In case of flexible walls, solid walls and floors the screws provided should be used. If the Multicollar Slim is mounted on Multimastic FB panels, Multiscrew FB (metal wobbles) should be used. For mounting in sandwich panels, M6 threaded studs (> EI60) or parkers ≥ 5.5 x 25 mm should be used for direct mounting (≤ EI60). Please refer to our installation manual for the correct installation sequence and method or contact our support team at: [email protected].

Air ducts are tested according to EN 1366-2, where the air pressure in the duct is 300Pa or 500Pa. The ducts are often made of metal and fitted with a band or butterfly damper at the fire separation. If an air duct is made of plastic and no fire damper or butterfly damper is provided, the Multicollar Slim may only be installed if the air flow of all inlet and outlet equipment connected to that duct are turned off in the event of a fire.

Air ducts are tested according to EN 1366-2, where the air pressure in the duct is 300Pa or 500Pa. The ducts are often made of metal and fitted with a fire damper or butterfly damper at the fire separation point. If an air duct is made of plastic and is not equipped with a fire damper or butterfly damper, the Multicollar Slim may only be installed if the air flow of all supply and exhaust equipment connected to that duct fails in case of fire.

Yes, before installing Mulcol products, steel pipes must always be free of dust, grease, and corrosion. If this is not the case, products may react differently after installation or during a fire. Still need help? Please contact our support team at: [email protected].

Air ducts containing fire dampers or butterfly fire dampers are tested in accordance with EN 1366-2. In many cases, elastomeric insulation is not included in the test. Based on EN 1366-3, Mulcol conducted a test with a Spiro duct (≤ Ø125 mm) fitted with elastomeric insulation (15 mm). In this fire test, Multisealant GR sealant was used around the insulation in 10x25 mm (wxd) for ≤ EI60 minutes. So there is a result but unfortunately the mentioned test cannot be classified according to EN 13501-1. Do you still have questions? Then seek advice from our support team via: [email protected].

To fulfil a requirement of ≤ EI60 minutes, a length of 50 mm Multimastic C in a thickness of 1.0 mm (WFT) is afoende. For a requirement of more than EI60 minutes, a length of 150 mm and a layer thickness of 1.5 mm (WFT) applies. This is also necessary when using a single Multimsatic FB2 (60 mm) baffle. Refer to the Multiselector for the correct finishing method.

The Multicollar Slim should always be mounted with the minimum number of tested Multiclips and sometimes also with Multiclips Large. This depends on the type of pipe, the required fire resistance and the pipe diameter. In general, a Multiclip should be provided after every 11 to 12 links, these should always be distributed evenly over the Multicollar Slim. Consult the Multiselector or the installation manual for the correct installation method.

Fire dampers must be finished as tested by the respective fire damper manufacturer. Different brands of firestop boards and mortar may be interchanged, provided they meet the minimum tested thickness and density. Still have questions? Then contact our support team at: [email protected]. Or visit the website of the relevant fire damper manufacturer.

The application of aperture framing and/or lining in gypsum walls depends on the specified fire resistance, aperture size and the number of Multimastic FB batts to be applied. In most cases, the use of aperture framing and/or lining is not necessary, for example when using a double Multimastic FB1 batt up to EI60 minutes. Consult the Multiselector for all tested situations.

Since it concerns air ducts that must be tested according to EN1366-2, a test with Multisealant GR, Multiwrap or the Multicollar Slim (in accordance with EN 1366-3) around the condensation insulation cannot be classified. We are happy to help you find the right (sufficiently safe) solution. Please contact our support team at: [email protected].

Yes, this is allowed. Cables, cable bundles, and other penetrations that have been tested in cable support systems may also be finished outside the cable support system. Consult the Multiselector for the tested configurations.

No, the Multidisc has so far only been tested in single and double wall sockets.

Annular spaces (≤ 20 mm) around penetrations, behind a Multicollar Slim or the Multitherm Bandage should always be fitted with Multimatic SP sealant. Annular spaces/crevices that are larger (> 20 mm) should be provided with Multimortar or the Multimatic C system, of course this must be tested. Therefore consult the Multiselector or the installation manuals for the correct installation method.

The space between the insert of the Multicollar Slim and the penetration may be ≤ 15 mm for outside diameters up to 125 mm. Above this, the spacing may be ≤ 5 mm maximum. A wider collar can be fitted more easily and is better exposed to irradiation in case of fire.

The Multitherm Bandage is mainly tested for copper and steel pipes. To use the Multitherm Bandage, these pipes should not get hotter than 60°C. For more technical details, please refer to the manual and TDS (Technical Data Sheet) of this product.

In order to receive sound advice from our support team, we would like to receive as much information as possible. Below are some details that need to be provided:

2. Construction (Gypsum, solid, CLT, sandwich panels...)
3. Structure of the construction (a sectional drawing is always welcome)
4. Aperture size
5. Type of penetration (steel, copper, PE, PVC, cable duct...)
6. Service dimensions
7. Insulation type, thickness and density, if applicable

When processing Multifoam 2K foams, the tubes should have a temperature of min. +20 °C. At a higher temperature, the product will foam better, more and faster. To keep the temperature of the tubes constant throughout the day, we recommend using our ‘Tempering box’.
