1 Cladseal Facade Waterproofing, Air Sealing & Damp Proof Course Application

2 The complete system for water, weather, moisture protection and air sealing of facades, windows and masonry walls During its lifetime, a building facade is subject to the effects of thermal and structural movements as well as wind and water, all under a wide range of temperatures and climatic conditions. These stresses and movements subject the waterproofing to a range of demands: it needs to be strong, elastic, weatherproof and resistant to industrial, polluted atmosphere. It needs to give a service life as long as the life of the building, with no loss in performance or properties. The Cladseal system provides an engineered waterproofing system meeting all these requirements. The Cladseal Product The EPDM and Butyl membranes, with their cross-linked molecular structure, have negligible aging over time, despite exposure to the atmosphere, sunlight, UV-radiation, chemical pollutions, water and extremes of temperature. EPDM and Butyl contain no plasticisers which can evaporate or be washed out over time or migrate to other materials. The strength and elasticity remains virtually unchanged over decades, without shrinkage, melting, hardening or cracking, and the membrane remains flexible at temperatures from -40 to +150 C. EPDM has a proven service life, defined as minimum 15 elongation at break, exceeding 50 years in exposed installations. EPDM and Butyl are also highly resistant to chemicals and attacks by rodents, fungi, bacteria and micro-organisms. They are also resistant to water absorption. EPDM and Butyl can absorb thermal and structural movements during linear elongation up to 30 and have a multiaxial elongation exceeding 10, at any temperature. Unlike most thermoplastic materials, EPDM has no yield point, even when deformed to extreme limits it will still return to its original shape, size and thickness. Due to its viscoelastic properties it can withstand an almost unlimited pressure load. Benefits of the Cladseal products Weather resistant. Resistant to atmosphere, UV light and airborne pollutions. Service life expectancy exceeds 50 years. Temperature resistant. Maintains its elasticity and extensibility irrespective of temperature. Biological resistant. Resistant to microbiological degradation, rodents, fungi and bacteria. Elastic. Can elongate over 300 %, with over 100 % multi dimensional elongation, and will always return to its original size and shape after elongation. Will therefore accommodate any thermal or structural movements in a building structure. Proven history. EPDM and Butyl membranes have been used for over 50 years in the building and civil engineering industry. The flexible membrane with the longest history. Tough and puncture resistant. Not affected by mechanical abuse, or extreme pressure loads. Resistant to building materials. EPDM and Butyl contain no plasticisers or additives that can migrate to other building materials and are compatible with any building substrates. Chemical resistant. EPDM or Butyl are not affected by other building materials, like mortar, cement, polystyrene, or acids. Not affected by water. EPDM and Butyl are completely unaffected by water and moisture, and absorb no measurable amount of water. Environment friendly products. Contains no environmental pollutants. Can be re-cycled, burned or disposed without any effects on the environment. An engineered Cladding system. All components and a full range of technical solutions from one supplier. Because of their stable molecular structure, EPDM or Butyl do not affect other building materials or cause migration, staining or discoloration. EPDM and Butyl have a low weight and a documented service life exceeding 50 years. They do not contain any CFCs, HCFCs, pthalates, dioxins, low grade hydrocarbons or other harmful chemicals. Because of this, a Life Cycle Assessment (LCA) is very favourable when compared to alternative products. Butyl has similar properties to EPDM, combined with a extremely low water vapour permeability. Comparison with thermoplastic materials - 40 C +150 C After elongation due to structural movements EPDM & Butyl Thermoplastic materials 4 4 At -40ºC EPDM and Butyl are unaffected, thermoplastics are stiff, brittle. At +150ºC EPDM and Butyl are unaffected, thermoplastics are liquids. After decades of flexing, EPDM and Butyl unaffected. Thermoplastics are thin and elongated, or cracked. 2 SealEco SealEco 3

4 Area of use The Cladseal System is the optimum material in the market to use for facade waterproofing, air sealing and damp proof course (often abbreviated to DPC). It is a complete system, which prevents rain and water from entering the buildings and prevents air leaks in the structure. Window and cladding applications (weatherstrips and airseals) Many window and cladding systems require an external waterproof seal and internal air seal between the framework and substrate. The Cladseal System provides a continuous moisture barrier that can accommodate structural movement. Installation of the Cladseal membrane is a simple process using specially formulated primer, cleaner, adhesive and sealant.

5 Damp Proof Course Applications The provision of a damp proof course has long been a requirement in construction. Brickwork and masonry must be protected from the damaging effects of water and moisture. The Cladseal strip provides a continuous barrier of protection and its life expectancy is much longer than traditional materials. Installation of the Cladseal strip membrane is a simple process using specially formulated primer, cleaner, adhesive and sealant. Its exceptional elongation and weathering properties are perfect for a temperamental climate. Paste Adhesive 3300 Sealant 5590 Primer 9800 Steel Frame Board Bonded at the Top Cladding Contact or Paste Adhesive Concrete The Cladseal Installation With five alternative application methods there is a suitable Cladseal solution to every facade, window or foundation construction and every type of substrate. The strips are available in any specified width from 50 mm up to 1700 mm to ensure the correct weatherproofing in any individual case. Bonding surfaces have to be dry and clean. Overlap seams between strips have to be sealed with sealants and porous substrates have to be coated with a primer to provide a good bonding surface. All components that are necessary are included in the Cladseal System: Product type Areas of use Suitable substrates or surfaces Polymer based high viscosity adhesive with low solvent content. Colour: black Polymer based contact adhesive containing inflammable solvents. Colour: black Silicone based sealant with low solvent content. Colour: black Solvent based primer, contains polymer.

Internal Brickwork Ventilation Gap External Brickwork Foundations/ Installation Instructions Surfaces to be bonded should be clean and dry. If any oil based products are present, these should be removed using Cleaning Wash 9800, before applying adhesive and then Cladseal. On porous substrates, e.g. concrete, the substrate must be primed before application. However, for a high density concrete priming might not be required and this should be evaluated on the site in real project conditions. Priming is possible by two methods. The first is to use Primer 9800 prior to the adhesive; the second is to use two layers of. The first layer should be thinned with Cleaning Wash 9700 which acts as a primer and the second layer is the adhesive layer. It is important that the first layer is left to fully dry (approximately minutes) before the second layer is applied. To check if the specified substrate is compatible with Cladseal System, please contact SealEco Technical Department. Cladseal with must be applied to both mating surfaces that are to be bonded together. Stir the Contact Adhesive carefully before use and apply with a solvent resistant stiff brush or roller. Allow both surfaces to flash off until touch dry (approximately 5-10 minutes). Bond together and apply pressure using a silicone or steel rubber roller. Make sure that the strip is applied without causing tension or stress to the splice. On extremely porous substrates where it is obvious that the Contact Adhesive vanishes into the material, the substrate shall be primed with Contact Adhesive (or Primer 9800) and left to dry before applying the second layer of adhesive to bond the Cladseal strip. We recommend that the bonding surface should be 100 mm wide or absolute minimum 50 mm. This gives an approximated consumption of g/m 2 depending on substrate. If the width of the bonding surface is less than 50 mm an additional mechanical fastening must be applied. Seams between Cladseal strips must have a minimum overlap of 100 mm, bonded together with Contact Adhesive Use Sealant 5590 on all overlap joints, cross joints and inner - and outer corner details. The sealant shall be applied under the lap and then pressed lightly until a 1mm bead is visible to ensure adhesion to both surfaces. Note: The adhesive must only be processed in dry weather conditions at temperatures of at least +5 C. When it has completely dried, the adhesive bond is resistant to temperatures up to +80 C.

6 Paste Adhesive 3300 Cladseal Ext, Int and Int+ Cladseal with Paste Adhesive 3300 Paste Adhesive 3300 is applied on substrates with a standard type of hand or electric gun or putty spade. Apply the paste in 2-3 beads to the substrate. Wait a couple of minutes before fixing the Cladseal membrane into the Paste. Spread the Paste or apply the Cladseal membrane directly over the beads so that a 1 mm thick layer of adhesive is covering a width of approx 100 mm. Apply pressure using a silicone or steel roller. The Cladseal membrane should be placed immediately after applying the adhesive. The Paste shall be applied and pressed until a 1 mm bead is visible outside the membrane edge, to seal the splice. Make sure that the strip is applied without causing tension or stress to the splice. Seams between Cladseal strips must have a minimum overlap of 100 mm, bonded together with Paste Adhesive The Paste shall be applied and pressed until a 1 mm bead is visible outside the membrane edge, to seal the splice. Note: The adhesive must only be processed in dry weather conditions at temperatures of at least +5 C. When it has completely dried, the adhesive bond is resistant to temperatures up to +80 C. Cladseal SA/Cladseal SA-Fix Cladseal SA is a scrim reinforced composite EPDM rubber sheet coated with adhesive Butyl that makes the sheet adhere to most available construction materials. Cladseal SA-Fix is a composite EPDM rubber sheet partly coated with adhesive Butyl that makes the sheet adhere to most available construction materials. Remove the protective foil and press the Cladseal to the substrate. Use a silicone or steel roller to apply pressure and get a good bonding between Cladseal SA/SA-Fix and the substrate. Make sure that the strip is applied without causing tension or stress to the splice. Porous substrates such as concrete and wood require priming before applying the Cladseal SA and Cladseal SA-Fix. Cladseal SA and SA-Fix must be mechanically secured at the top to avoid sliding. Seams between Cladseal strips shall be made with or Paste Note: Cladseal SA and Cladseal SA-Fix must not be applied in temperatures below 5 C. Cladseal SA is an EPDM strip with an EPDM profile attached on one side. During installation, the profile shall be firmly pressed into the mounting recess. It is possible to use silicon as an anti-friction agent for easier mounting. The side on the strip without profile must be glued to the substrate with Contact Adhesive or Paste Adhesive The area that shall be glued must be free from silicone to gain sufficient adhesion. Make sure that the strip is applied without causing tension or stress to the splice. Technical guidance Contact SealEco Technical Department for assistance with any questions.

7 Air Sealing Everything you need Air Sealing is one of the most important energy savings that can be made to a building s structure. The sealing process improves the thermal comfort of buildings, their durability and also enables ventilation control. If the building envelope is not properly sealed, air leakage will occur. This will cause heat loss or gain through the transport of cold or hot air respectively and can increase the interstitial condensation and discomfort caused by drafts, noise and moisture. Air-leakage can cause losses of between 25-4 of the overall energy used for cooling and heating. This amount would obviously depend upon the type of the structure and it will be directly proportional to the number of leaking points. The air leakage is determined by the pressure difference between the outside and inside of the building, due to wind and temperature differences. Mechanical systems (heating and ventilation) will also influence the air flow in the building. The air leakage paths can be easily sealed during the construction process. The current requirements regarding the air tightness of buildings can be found in Part L (Conservation of Fuel and Power) of the Building Regulations. The requirements regarding the air-tightness test have been revised routinely and should be taken into account during the design process. It is likely that air-tightness will continue to increase in line with changing legislation. The air-tightness test is measured as a rate of leakage per square meter of external envelope per hour at an artificial pressure differential through the envelope The pressure and the air leakage rate will depend upon the building specification. Air sealing is a necessity for the building envelope. Cladseal INT, INT+ and Cladseal SA products have excellent water vapour permeability properties and can be used as an air-barrier inside of the building.
