1. Summary Effisus Vapour FR works as an airtight vapour control layer (AVCL), protecting the building from the risk of condensation and improving its airtightness and, consequently, energy efficiency. The Effisus Vapour FR wall lining membrane is a high-quality multifunctional waterproofing and fireresistant vapour barrier, made of a specialized fiberglass fleece. Effisus Vapour FR Membrane can be applied to walls or ceilings to prevent heat radiation and moisture transfer. It also serves as an effective fire-retardant layer for building projects. Figure 1 - Effisus Vapour FR System 2. Scope of Usage In General: Wall lining membrane. 3. Presentation and Product Details 3.1 Effisus Vapour FR Membrane Standard roll width: 1.20m Roll length: 50 m Thickness: 0.148mm ± 0.015mm Colour: Black. Characteristics: see the table below.

a) Vapour resistance test result based on the vapour permeability of still air in the UK: 0.2 gm/MNS. The Effisus Vapour FR system comes with a number of accessories specifically designed to facilitate the application of the membrane. Adhesive tape for moisture proof sealing of Effisus Vapour FR Membrane overlap and perimeter sealing. These tapes are suitable for bonding Effisus Vapour FR Membrane to smooth, non-porous and porous substrates. Effisus 2Adjoin DF is a double-sided, airtight, water and moisture-resistant sealing tape, suitable for fixing Effisus membranes, PE/PA/PP and aluminium...

4.1.2 Effisus 2Bond DS Tape (sealing membrane edges) Effisus 2Bond DS is the most efficient solution for sealing two surfaces of the same ordifferent materials, and for sealing any nail/screw penetrations. Effisus 2Bond DS tape is a double-sided adhesive tape, devised using advanced technology with active adhesive sealants. Designed using a chemical arrangement of thermoplastics and non-curing rubber (non-butyl) with an incorporated primer, Effisus 2Bond DS is thoroughly elastic and flexible within a temperature range of 93ºC to -57ºC. With a highly advanced micro sealant and removable siliconized...

4.2.2 Effisus Coat NP Prime Primer to prepare surfaces before bonding Effisus Vapour FR membrane. The primer should be used for surface treatment before applying Effisus 2Bond DS tape: - when applying on moist porous substrates; - within a temperature range of -10 ºC to 5 ºC. Package: 4.5 Kg 4.2.3 Effisus Cleaner LV Effisus Cleaner LV is a ready-to-use solvent-based cleaning liquid and is used for cleaning and degreasing surfaces. It is compatible with all the products that constitute the Effisus waterproofing system. 5. Production, marketing and technical solution Effisus supplies Effisus Vapour...

Rolls should be stored flat on their sides, on a smooth, clean, dry surface, under cover, protected from sunlight and extreme weather conditions or the risk of puncture. - Effisus Vapour FR 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 Vapour FR System accessories, surfaces mustbe thoroughly cleaned using Effisus Cleaner LV. The substrate should also be...

6.2.1 Fixing membrane to the substrate Figure 4 - Effisus Vapour FR Membrane – Fixing to the substrate 6.2.1.1 Effisus 2Adjoin DF Tape Effisus Vapour FR membrane should be applied to the sheathing board using a 25mm-wide band ofEffisus 2Adjoin DF Tape, with a maximum spacing of 600mm//600mm. The membrane should immediately be mechanically fixed on its edges. For more information on this accessory and its compatibility with other materials, see 4.1. 6.2.1.2 Effisus 2Bond DS Tape (Alternative) The Effisus Vapour FR membrane should be fixed using a 25mm-wide band of Effisus 2Bond DS Tape, with a...

Figure 5 - Effisus Vapour FR Membrane – Overlapping Joints. 6.2.2.1 Effisus 2Adjoin DF Tape Joints should be sealed with 2 bands 25mm-wide of Effisus 2Adjoin DF Tape. 6.2.2.2 Effisus Bonding KF+P Paste Adhesive (Alternative) Joints should be sealed with 2 beads 8mm-diameter of Effisus Bonding KF+P paste adhesive. 6.2.2.3 Effisus 2Bond DS Tape (Alternative) Joints should be sealed with 2 bands 25mm-wide of Effisus 2Bond DS Tape. Figure 6 - Effisus Vapour FR Membrane – Overlapping Joints. 6.2.3.2 Effisus 2Bond DS Tape Effisus Vapour FR Membrane should be sealed continuously around the membrane...

If there is any risk of sliding or stress to the membrane, this should be mechanically fixed around its edges. For more information about this accessory and its compatibility with other materials see 4.1. 6.2.3.2 Effisus Bonding KF+P Paste Adhesive (Alternative) Effisus Vapour FR Membrane can, alternatively, provide a continuous seal around the membrane perimeter and in all locations interrupting the continuity of the AVCL layer, such as window frames, doors, perforations or the like, using an 8mm-diameter bead of Effisus Bonding KF+P paste adhesive. This alternative to Effisus 2Bond DS will...

6.2.5 Bond between Effisus Vapour FR Membrane – Effisus ProFlex FR Membrane Bonds between an Effisus Vapour FR Membrane and an Effisus Ecofacade (EPDM) Membrane should be made using a 25 mm-wide band of Effisus 2Bond DS Tape, or an 8mm-diameter bead of Effisus Bonding KF+P Adhesive. 6.2.6 Bond between Effisus Vapour FR membrane – Effisus Vapour FR membrane Bonds between an Effisus Vapour FR and an Effisus Breather FR Membrane should be made using 2 bands 25 mm-wide of Effisus 2Adjoin DF Tape or 2 bands 25 mm-wide of Effisus 2Bond DS Tape. 7. Repairs In case of puncture to the membrane, sealing...

effisus8. Compatibility Effisus Vapour FR Membranes are compatible with all traditional building materials. However, if in doubt, carry out a compatibility test and consult Effisus Technical Department. Whenever Effisus Vapour FR Membranes are to be used in vigorous work environments (workshops,laboratories, etc.) Effisus Technical Department must be consulted. Technical details are presented in this document. Effisus Vapour FR obtained class A2-s1,d0 rating as a System and class A1 rating as a Membrane to Test Standard EN13501.
