VFB Plus VFB Plus Ventilated Fire Barrier Tenmat’s VFB Plus Ventilated Fire Barriers are “open state” cavity fire barriers designed to offer fire resistance performance within external wall cavities that require permanent (open-state) ventilation in non-fire conditions. Passive Fire Protection VFB Plus Product Description Technical Data Sheet Tenmat’s VFB Plus Ventilated Fire Barriers are ’open state’ cavity fire barriers for ventilated cavities of up to 450mm. Each VFB Plus consists of a specially formulated fire rated stone mineral wool section with an integral high expansion intumescent seal fixed to the leading edge. The VFB Plus then leaves a maximum 44mm air gap to allow for drainage and maintain ventilation in normal use. In a fire situation the intumescent seal rapidly expands to seal off the air gap and prevent vertical fire spread within the external wall. The product has undergone extensive fire testing following the principles of BS EN1363-1 and in accordanc

e with ASFP TGD19 (Fire Resistance Test for ‘Open-State’ Cavity Barriers). The VFB Plus are mechanically fixed horizontally within ventilated cavities behind the external wall substrate following the fire compartment line. The VFB Plus are used horizontally and can be installed in conjunction with Tenmat NVFB Non-Ventilated Fire Barriers which provide vertical fire separation along fire compartment party wall lines.

Insulation is tested interrupted to prevent the possibility of fire bypassing behind the cavity barrier. The ASFP-TGD19 test standard allows for insulation to be replaced with insulation that is listed as better using the hierachy as below and must be installed interrupted. Notes on insulation from TGD19:2017-13.3 Insulation. For interrupted insulation the following hierachy is used: Best- stone wool, glass wool, phenolic, PIR, PUR, EPS - Worst Technical Information Colour Red Finish Polythene Wrap Cuttability Can be cut to length

VFB Plus General Design & Installation Considerations Technical Data Sheet Maximum free air gap for this cavity barrier is 44mm, the space in front of the intumescing strip on the face of the cavity barrier to the rear of the external wall surface. Open state cavity barriers should be installed in a continuous run, (with the exception of abutting up to full fill vertical cavity barriers). Where this is not possible,

details should be agreed with the projects principal designer and or fire engineer. Horizontal cavity barriers should be installed adjacent and tightly abutted to any vertical cavity barriers, the vertical cavity barriers should be installed first. Cavity barriers may be cut to length as required, adjacent lengths must be tightly abutted together. The intumescing face of the cavity barrier should be unrestricted and free to expand in a fire situation, fully filling the cavity. An identification label is attached to the intumescing face of the cavity barrier, ensure this faces out into the open cavity. Also ensure the label is visible and legible and reads the right way up. If the identification label is not legible please contact Tenmat, the label is important in terms of identifying the product in the future, for example during fire risk assessments or fire safety inspections.

netrate through the face of the cavity barrier. Screws for direct fixing and fixings to secure brackets are not supplied by Tenmat. The brackets used to fix the horizontal cavity barrier must be installed with the spike inserted centrally (horizontally) to the rock mineral wool section of the cavity barrier with the bracket fixed above and not below the cavity barrier. The use of tape is not required over the joints between the lengths of cavity barrier, and if used should not be applied over the face of intumescent material. The cavity barrier must be installed following the installation methods described below. The cavity barrier must not be penetrated by any other mechanical or electrical services.

This can be located on the front edge of the fire barrier underneath the polythene seal. If no fixing is located, then either another section of fire barrier should be used or alternatively a further stainless steel , countersunk head screw with max. 11.5mm head diameter and a min. length of 65mm should be fixed at the mid-point. No additional fixings to the front face are required for product widths greater than 76mm as the intumescent seal is already mechanically screw fixed during the manufacturing process, unless the product is cut to sections of <250mm. Screws for direct fire barrier fixing refers to stainless steel, countersunk head screws, max. 11.5mm head diameter, suited to the substrate in question. If f

ire barrier is directly screw fixed, the screws should penetrate the fire barrier at the mid point and should finish flush or slightly proud of the front face. Care should be taken not to overtighten as this may affect the performance of the intumescent seal. Fixings for brackets should be non-combustible and suited to the substrate. It must also be ensured that any bracket fixing does not prevent the back of the fire barrier from fitting tightly against the substrate ensuring no gaps. Brackets must impale the fire barrier at mid thickness. Brackets should not penetrate the front face of the barrier and if required should be cut down in length to prevent this. Screws for direct fixing and fixings to secure brackets are not supplied by Tenmat. For fire barriers cut down in length <200mm, minimum one support required. For cut sections >201mm minimum two supports required and/or follow above table. For cavities less than 40mm, contact Tenmat for alternative products. VFB Plus Option 1

Ensure that the countersunk screw head does not fully penetrate the face of the cavity barrier, the screw head should sit flush or slightly proud. 125mm 250mm Position the first screw fixing through the centre line of the face of the cavity barrier at a maximum 125mm from one end, continue to face fix through at maximum 250mm centres (4 screws per linear meter), ensuring that the final fixing is a maximum 125mm from the end of the cavity barrier. This will ensure that face fixings are positioned at 250mm centres across the continuous run of cavity barrier. Where sections of cavity barrier are less than 1 linear meter in length, ensure that face fixings are positioned at a maximum 125mm from each end with additional fixing being pos

itioned at maximum 250mm centres between the end fixings. For cut sections of cavity barrier less than or equal to 250mm in length only one fixing is required. VFB Plus Technical Data Sheet Option 2 VFB Plus- Product width across cavity from 77mm up to 90mm, fixed using 2 multi purpose (MP) 65mm brackets. A MP brackets are supplied with 2 fixing spikes, one spike is 65mm long (A), the other is 160mm long (B), with a central pre drilled section for securing the bracket to the substrate. B For cavity barriers 77mm-90mm wide (across cavity) use 2 MP brackets and the 65mm long spike (A). To secure the bracket use 5mm Ø stainless steel countersunk head screws, with a maximum head diameter of 13mm and with a length and type suitable for the substrate. Ensure that the countersunk screw head sits as flush as possible with the substrate. Fix through both of the fixing holes.

the cavity barrier, with a maximum spacing between brackets of 500mm. Where sections of cavity barrier are less than 1 linear meter in length, ensure that MP brackets are positioned at a maximum 250mm from each end. For cut sections of cavity barrier less than or equal to 500mm in length only one MP bracket is required. Push the cavity barrier onto the bracket spike, the brackets should impale the VFB Plus to approximately mid barrier depth and must not protrude through the intumescent element. The cavity barrier should be pushed fully onto the bracket spike and sit flush with the substrate, at the rear of the cavity barrier.
