VFB 60/60 VFB 60/60 Ventilated Fire Barrier Tenmat’s VFB 60/60 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 60/60 Product Description Technical Data Sheet Tenmat’s VFB 60/60 Ventilated Fire Barriers are ’open state’ cavity fire barriers for ventilated cavities of up to 450mm. Each VFB 60/60 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 60/60 then leaves a maximum 25mm 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 products have undergone extensive fire testing following the principles of BS EN1363-1 and in

accordance with ASFP TGD19 (Fire Resistance Test for ‘Open-State’ Cavity Barriers). The VFB 60/60s are mechanically fixed horizontally within ventilated cavities behind the external wall substrate following the fire compartment line. The VFB 60/60s 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.

ric approval for these insulation products and approval should be sought from the insulation manufacturers depending upon the particular type of construction being built. Insulation is tested interrupted to prevent the possibility of fire bypassing behind the cavity barrier. Testing using a combustible substrate covers a limited combustible or non-combustible substrate. The ASFP-TGD19 test standard allows for insulation to be replaced with insulation that is listed as better using the hierarchy as below and must be installed interrupted. Notes on insulation from TGD19:2017-13.3 Insulation. For interrupted insulation the following hierarchy is used: Best- stone wool, glass wool, phenolic, PIR, PUR, EPS - Worst Technical Information Colour Black Finish Polythene Wrap Cuttability Can be cut to length Working Life 40-60 years (see below) Storage Dry, ambient Transportation Storage Temperature -20°C to +70°C Durability Type X intended for use in conditions exp

VFB 60/60 General Design & Installation Considerations Technical Data Sheet Maximum free air gap for this cavity barrier is 25mm, 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 cavi

ty 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. Cavity barrier fixing brackets, both multi purpose, (MP bracket) or high performance (HP bracket) must not penetrate 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 b

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.

Use stainless steel countersunk head screws, with a maximum head diameter of 11.5mm and with a length suitable for the size of cavity barrier and sufficient fixing depth into the substrate. Fixings must have an appropriate fixing depth for the substrate (with a minimum of 50mm for masonry fixings and minimum 25mm for timber unless otherwise specified by the fixing manufacturers guidance for their fixing type). 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. Care should be taken not to over tighten as this may affect the performance of the intumescent seal. Position the firs

B For cavity barriers 76mm-90mm wide (across cavity) use 2 MP brackets and the 65mm (A) long spike. To secure the bracket use nom. 5mm Ø stainless steel screws/fixings, with a maximum head diameter of 13mm and with a length and type suitable for the substrate. Ensure that the screw head sits as flush as possible with the substrate. Fix through both of the fixing holes. A Fixings must have an appropriate fixing depth for the substrate (with a minimum of 50mm for masonry and minimum 25mm for timber unless otherwise specified by the fixing manufacturers guidance for their fixing type).

ets 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 60/60 to 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, ensuring that there are no gaps behind the cavity barrier.

gs are positioned at 250mm centres across the continuous run of cavity barrier. The pigtails should be screwed in to the face of the cavity barrier to a depth which leaves 25mm of the pigtail proud of the intumescing face of the cavity barrier. Where sections of cavity barrier are less than 1 linear meter in length, ensure that pigtails are positioned at a maximum 125mm from each end with additional fixing being positioned at maximum 250mm centres between the end pigtails. Where the space between the end pigtails exceeds 250mm additional pigtails will be required. Where the cavity barrier is less than 250mm in length only 1 pigtail will be required. All sections of cavity barrier require pigtail screws unless directly faced fixed through the cavity barrier, as per option 1.
