Description

NOTE: The Integrity and Insulation rating of this product is limited to the capability of the surrounding substrates, Nullifire/Firetherm does not permit the use of this product against combustible cladding.

Nullifire FJ240 Spanatherm is a dry fit system designed to be a cost-effective and efficient method of firestopping static and movement joints for slab edge/curtain walling or vertical details. The strong pre-engineered rock fibre movement-joint fire seal allows significant movement accommodation at the same time as providing fire integrity, insulation and an effective smoke seal. The dense fibrous system is faced on both sides with foil to provide Class O surface spread of flame and a vapour check barrier.

Maximum Openings


Facade and internal movement and slab edge seals up to 550 mm (maximum gap width +/- 7.5% movement.

Where the opening width exceeds 50 mm or the cladding system is flexible, Z Clips or V-lock Z Clips will be required to provide sufficient support in relation to gap width. Please refer to the relevant data sheets and application guides for more information, or contact our technical team on 0113 2455450.



Size


Spanatherm is supplied in 1200 x 600 x 100mm thick slabs - contact us on 0113 2455450 for custom size requirements.



Typical Installation


  1. Clean all surfaces to remove loose debris, dirt and grease.
  2. Carefully remove Spanatherm from its packaging.
  3. Measure the gap width of the opening to be sealed.
  4. Cut the Spanatherm into strips lengthways to the width of opening plus approximately 10% (minimum 5 mm) to ensure a compressed joint.
  5. Under compression, install the cut length of Spanatherm. Where the opening width exceeds 50 mm or the cladding system is flexible, Z Clips or V-lock Z Clips will be required to provide sufficient support in relation to gap width. The clip is fixed into the slab side edge of Spanatherm and mechanically fixed to the top of the floor slab. Clips/Spikes required: 3 per 1.2 m at 400 mm centres working from the centre line, minimum 2 per cut piece.
  6. Butt join additional lengths of Spanatherm along the seal as required.
  7. Seal adjoining edges of Spanatherm using suitable adhesive backed foil tape.
  8. When used vertically the smoke seal must be applied to both faces of the product.

Where it is not possible to scribe the product, discontinuities or Irregularities up to 25 mm can be sealed using Intumastic or Intumastic ADL to a 1:1 ratio in conjunction with a minimum 64 kg RF backer to the remainder of seal depth. This should only be used in C1, C2 or C3 Environments, For C4, Intusil should be adopted.



Fire Testing


Spanatherm has been rigorously tested to BS 476 Pts 20 and 22: 1987 at a UKAS accredited laboratory for up to two hours fire integrity and 90 minutes insulation.
