CI/SfB (42) Ln6 IRISH AGRÉMENT BOARD CERTIFICATE NO. 07/0297 Moll bauökologische Produkte GmbH, pro clima, Schwetzingen, Germany. Tel: 046 9432104 Fax: 046 9432435 Email: info@ecologicalbuildingsystems.com Website: www.ecologicalbuildingsystems.com pro clima Intelligent Airtight System Système intélligent d’étanchéité à l’air Intelligentes Luftdichtungssystem NSAI Agrément (Irish Agrément Board) is designated by Government to issue European Technical Approvals. NSAI Agrément Certificates establish proof that the certified products are ‘proper materials’ suitable for their intended use under Irish site conditions, and in accordance with the Building Regulations 1997 to 2007. PRODUCT DESCRIPTION: This Certificate relates to the pro clima Intelligent Airtight System which consists of a range of intelligent vapour checks (INTELLO, INTELLO PLUS and DB+), tapes, adhesives, and the Wincon airtightness quality control fan. This Certificate certifies compliance with the requirements of the Building Regulations 1997 to 2007. USE: Airtightness is the control of air leakage, i.e. the elimination of unwanted draughts through the fabric of the building envelope through the correct and proper installation of a vapour check or vapour barrier. Consequently condensation, mould, rot, damp and structural damage are also eliminated, ensuring a more viable structure, an insulation layer that can perform properly as it is now protected against penetrating moisture, reducing the amount of energy-in-use in the building and CO2 emissions. The airtightness layer prevents uncontrolled air infiltration, i.e. air convection, while air exchange from inside to outside by ventilation still occurs. The quality of airtightness is determined by the freedom from leakages in the building envelope, i.e. the more leakages there are in the inner building envelope such as the vapour check, the poorer the airtightness. Interior air flowing to the outside through leaks in the vapour check transports heat and consequently leads to a higher heating energy demand. As it flows through the thermal insulation, the warm air cools and condenses on the exterior building elements. This precipitating moisture in the structure, referred to as condensation, leads to mould formation which may remain undetected for a considerable period of time and can lead to structural damage. Readers are advised to check that this Certificate has not been withdrawn or superseded by a later issue by contacting NSAI Agrément, NSAI, Santry, Dublin 9 or online at http://www.nsai.ie/modules/certificates/uploads/pdf/IAB070297.pdf

Mould occurs not only when the actual temperature drops below the dew point, i.e. when condensation precipitates, but also if the relative humidity lies above 80% for extended periods of time within building elements. Reduction in surface temperatures of building elements can be caused by thermal bridges or by defective airtightness. The colder it is outside, the more the building elements will cool. A damp room climate leads to a higher dew point temperature and mould limit temperature and therefore an acceleration in mould growth. The dry air that is often found in rooms in wintertime is...

Part L – Conservation of Fuel and Energy L1 – Conservation of Fuel and Energy The pro clima Intelligent Airtight System, when installed and used in accordance with this Certificate, can meet this requirement and contribute to less air leakage in the building and therefore less heat loss. A key parameter for achieving an efficient Building Energy Rating (BER) is that the building envelope is designed and insulated to a high level and the fabric airtightness is to a high standard.

Figure 1: Bonding of Intello Plus to Concrete Slab using ORCON F ORCON & ORCON F ORCON F contains denatured alcohol (15%) allowing it to penetrate deep into stone substrates ensuring a very tight bond. The alcohol content means that the adhesive can be safely stored outside at temperatures as low as o –20 C. ORCON is a similar adhesive but contains no alcohol and dries fast after application. These adhesives are suitable for bonding all of pro clima’s vapour checks and air-proofing membranes to other building materials regardless of whether they have a smooth or rough surface. All surfaces...

TESCON No.1 TESCON No.1 is the same tape as TESCON PROFIL but has just one release paper and is used as a multipurpose tape for overlaps, service penetrations and repairing damaged areas. Rolls are 60mm wide and 30m long. TESCON INVIS TESCON INVIS is designed to conceal sealed overlaps in SOLITEX WA when one is planning a cladding with opened joints. It is a multipurpose tape to seal overlaps between foil and fleece membranes and joins between such membranes and smooth, nonmineral surfaces. It is also suitable for sealing butt joints between wood based panels such as OSB. Rolls are 60mm...

Airtight Grummets KAFLEX & ROFLEX and TESCON No.1 Tape for Sealing Cables and Pipes Grummets are made from non-ageing elastic EPDM and are available in a range of sizes from 6 up to 220mm. The grummets available are: • Single (KAFLEX mono), double (KAFLEX duo) or multi (KAFLEX multi – up to 16 cables) cable grummets (see Figure 3) • Pipe grummets (ROFLEX 20 to ROFLEX 200) (see Figure 4) Pipes should also be sealed with the elastic adhesive tape TESCON No.1 (see Figure 4). INSTAABOX 2.3 DELIVERY, STORAGE AND MARKING Rolls are supplied on pallets, wrapped in PE foil with product information...

Figure 4: Roof Detail with Pipe Grummet Newly built houses have high indoor humidity levels due to moisture released during construction and due to use. The diffusion resistance of the vapour check should be such that it is at least 10MNs/g even at an average humidity of 60% (room humidity 70%, humidity within the construction 50%) in order to adequately protect the structure from airborne humidity. INTELLO PLUS has a diffusion resistance of approximately 20MNs/g at a relative humidity of 60%. During construction, when plaster or screed is being laid, the humidity in a building can be very...
