1. Summary Effisus Breather FR UV Membrane is a non-combustible waterproofing, airtight and vapour permeable membrane, made of a fiberglass fabric and a black special coating. Effisus Breather FR UV membrane has exceptional UV resistance ideal for perforated and open joints rainscreen cladding systems. It is suitable for application on façades with 100% permanent exposure. Protects the building against driving rain, moisture improving facade resistance to fire and preventing futurecorrosion and insulation deterioration. Increases the building energy efficiency.

4.1.1 Effisus 2Adjoin DF Tape (fixing to structure / membrane overlaps) Effisus 2Adjoin DF is a double-sided, airtight, water and moisture-resistant sealing tape, suitable for fixing Effisus membranes, PE/PA/PP and aluminium foils to metal studs. It is suitable for windtight and water/moisture-proof sealing of external membranes, as well as for rain-proof taping of roof underlay. It is quick and easy to apply using the Effisus 2Adjoin DF Hand Dispenser. Compatible substrates Designed for fixing internal membranes to metal sections in dry construction and the fixture of external membranes to hard-based...

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. Roll width: 60mm. Roll length: 30m. Colour: Black. 4.2 Accessories: Others 4.2.1 Effisus Coat NP Prime Primer to prepare surfaces before bonding Effisus Breather FR UV 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 4.2.2 Effisus Cleaner LV Effisus Cleaner LV is a ready-to-use...

- Effisus Breather FR UV 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 UV System accessories, surfaces mustbe 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 - 10°C...

the function of temporarily secure the Effisus Breather FR UV membrane until it is mechanically fixed. 6.2.1.2 Effisus 2Bond DS Tape (Alternative) The Effisus Breather FR UV membrane should be fixed using a 25mm-wide band of Effisus 2Bond DS Tape, with a maximum spacing of 500mm//500mm. For more information on this accessory and its compatibility with other materials, see 4.1. 6.2.2 Overlapping Joints Upper layers should always overlap lower layers to facilitate the runoff of rainwater and to avoid water accumulation at the overlap joints. - Horizontal joints should overlap by 100mm minimum....

All nail/screw perforations <25mm in diameter should be sealed with a 50mm x 50mm patch of Effisus2Bond DS Tape, a double-sided adhesive/sealant tape (thickness > 1,50mm). Irregularly shaped facade perforations over 25mm in diameter should be studied in detail on a case-by-case basis by the Effisus Technical Department. To seal cables, pipes and other perforations, Effisus has a variety of solutions that can be used to seal them. For projects with high requirements or unusual shapes, Effisus developed customized solutions capable of accommodating the most difficult perforations in any type of...

6.2.5 Bond between Effisus Breather FR UV Membrane – Effisus ProFlex FR Membrane Bonds between an Effisus Breather FR UV Membrane and an Effisus ProFlex FR Membrane should be made using a 25 mm-wide band of Effisus 2Bond DS Tape, or an 8mm-diameter bead of EffisusBonding KF/KFP paste adhesive. 6.2.6 Bond between Effisus Breather FR UV membrane – Effisus Vapour FR membrane Bonds between an Effisus Breather FR UV and an Effisus Vapour FR Membrane should be made using 2bands 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...

effisus8. Compatibility Effisus Breather FR UV Membranes are compatible with all traditional building materials. However, if in doubt, carry out a compatibility test and consult Effisus Technical Department. Whenever Effisus Breather FR UV 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 Breather FR UV obtained class A2, s1-d0 ratingas a System according to the Standard EN13501, and Class A (or class 1) on ASTM E84. The Effisus Breather FR UV membrane...
