1. Summary Effisus Breather FR-B Membrane is a fire rated class B waterproofing breathable membrane, made of nonwoven polyester with a waterproof special coating. Effisus Breather FR-B Membrane has exceptional UV resistance and is designed for open or closed rainscreen cladding systems, cavity and masonry, leaf weatherboarding panels, tile/slate and timber frame cladding. Suitable for façades with open joints up to 50mm and maximum up to 50% of façade area. Protects the building against driving rain, moisture improving façade resistance to fire and preventing futurecorrosion and insulation deterioration. Figure 1 - Effisus Breather FR-B System. 2. Scope of Usage In General: Wall lining membrane. 3. Presentation and Product Details 3.1 Effisus Breather FR-B Membrane Standard roll width: 1.50m Roll length: 50m Thickness: 0.6mm Color: Black Characteristics: see Table below.

a) The fire classification was obtained with Effisus accessories (double side adhesive tapes) tested as a system. b) In accordance with Annex C of EN 13859-2 (EN 12311-1). c) In accordance with Annex C of EN 13859-2 (EN 1928). d) For more information about the american standards, please contact Effisus Technical Department The Effisus Breather FR-B System includes accessories that are designed specifically to simplify the application of the membrane. Adhesive tape for a moisture proof sealing of Effisus Breather FR-B Membrane overlaps, perforations an perimeter sealing. 4.1.1 Effisus Adjoin TI...

Effisus Adjoin TI Tape is also suitable for sealing joints between wood-based panels such as OSB or MDF subroof panels or wood-fiber softboards (e.g., Gutex). Bonds overlaps between sheets of vapour check and joints between wood-based panels (such as OSB) also seals service penetrations. Suitable for windows, doors, planed timber, corners and roof windows. Offers high protection against piercing in corners due to its high elasticity. With release paper. Easy to tear by hand. Roll width: 60mm. Roll length: 30m. Colour: Black. 4.1.2 Effisus 2Adjoin DF Tape (membrane positioning) Effisus 2Adjoin...

4.2 Paste Adhesives Paste adhesives for moisture and air proof sealing of Effisus Breather FR-B Membranes edges. The paste adhesives are suitable for bonding Effisus Breather FR-B Membrane to smooth, non-porous and porous substrates, being used for the perimeter sealing and fixing it to the substate. For this sealing/fixing, Effisus provides 3 different types of paste adhesives compatible with Effisus Breather FR-B: Effisus Bonding KF+P Adhesive, Effisus Bonding KF Adhesive and Effisus Bonding KFP Adhesive. 4.2.1 Effisus Bonding KF+P Adhesive (fixing to substrate / perimeter sealing) Effisus...

4.2.3 Effisus Bonding KFP Adhesive Effisus Bonding KFP adhesive brings together on a single adhesive exceptional property of adhesiveness, waterproofing and UV resistance, allowing total freedom of work. With exceptional bonding strength it is especially suitable for rough, uneven surfaces. Waterproofing and UV resistant, with the Effisus Bonding KFP adhesive no additional sealing materials are required. With the Effisus Bonding KFP adhesive, sealing can be carried out at temperatures down to –10°C and on moist (absorbent) building surfaces using Effisus Coat NP Primer. Compatible substrates:...

- Effisus Breather FR-B Membrane should be carefully transported and applied, to avoid sharp substrate edges, dust and debris contamination and the risk of tearing or loss of integrity. - Bonding should be carried out on clean, dry, grease and dust-free supports. - Surface preparation: - Before applying any Effisus Breather FR-B System accessories, surfaces must be thoroughly cleaned using Effisus Cleaner LV. The substrate should also be degreased completely. - A primer should be used for surface preparation and treatment of porous surfaces, or application within a temperature range of 5°C -...

If the membrane is applied on the sheathing board and immediately covered by the insulation (see Figure 1), the Effisus Breather FR-B membrane does not need to be mechanically fixed. After applying the Effisus Bonding KF+P Adhesive or Effisus 2Adjoin DF Tape on the substrate, directly apply the Effisus Breather FR-B Membrane over the surface and apply pressure over the whole bonding area using a silicone roll. Note: Instead of Effisus Bonding KF+P Paste Adhesive, the Effisus Bonding KF and Effisus Bonding KFP adhesives can be used. The selection of the most suitable adhesive depends on each project’s...

6.2.4 Perforations sealing 6.2.4.1 Effisus 2Bond DS Tape All nail/screw perforations <25mm in diameter should be sealed with a 50mm x 50mm patch of Effisus 2Bond DS Tape, a double-sided adhesive/sealant tape (thickness > 1,50mm). Irregularly shaped façade perforations over 25mm in diameter should be studied in detail on a case-by-case basis by the Effisus Technical Department. When Effisus 2Bond DS Tape is not used on insulation perforations (e.g. insulation mushroom washers or insulation pinholes), the head/top of these elements should be fully sealed with Adjoin TI Tape. To seal cables, pipes...

6.2.5 Bond between Effisus Breather FR-B Membrane – Effisus ProFlex FR Membrane Bonds between an Effisus Breather FR-B Membrane and an Effisus ProFlex FR Membrane should be made using an 8mm-diameter bead of Effisus Bonding KF Adhesive or KFP Adhesive or Effisus Adjoin TI Tape. 6.2.6 Bond between Effisus Breather FR-B membrane – Effisus Ecofaçade membrane Bonds between an Effisus Breather FR-B Membrane and an Effisus Ecofaçade (EPDM) Membrane should be made using an 8mm-diameter bead of Effisus Bonding KF+P Adhesive (or another Effisus adhesive) or Effisus Adjoin TI Tape. 7. Repairs In case of...

Effisus Breather FR-B Membranes are compatible with all traditional building materials. However, if in doubt, carry out a compatibility test and consult Effisus. Whenever Effisus Breather FR-B Membranes are to be used in vigorous work environments (workshops, laboratories, etc.) Effisus must be consulted. Technical details are presented in this document. Effisus Breather FR-B membrane has CE certification and DoP based on EN 13859:2, Flexible sheets for waterproofing. Definitions and characteristics of underlays. Underlays for walls (EN 1928, EN 13111, EN ISO 12572, EN 12311-1, EN 12310-1, EN...
