2 APPLICATION MANUAL 1 - General >> Working with Armaflex Tuffcoat General >> Working with Armaflex Tuffcoat WORKING WITH ARMAFLEX TUFFCOAT Armaflex Tuffcoat tubes and sheet are Class O Armaflex material laminated with a tough PVC film. The more rigid covering means fabrication of segmented bends and t-pieces is required more often when working with the product. Use good quality tools, in particular a sharp knife, fresh Armaflex adhesive and a good brush. Oval tubes should always be split on the flat side. A section of the Tuffcoat tube covering has a selfadhesive backing to help simplify application. Once the tube is fixed in position peel off the self-adhesive backing and fix down the covering. Armaflex Tuffcoat can be installed outdoors since the covering is UV resistant and protects against mechanical impact and bird attack. 25mm wide tape should be used to cover linear seams and 12.5mm tape for segmented bends. 50mm wide tape is available for ductwork seams. Mastic should be used to seal elbows and t-piece fittings outdoors and for all other seams in washdown areas to ensure a water tight seal. TOOLS & ACCESSORIES FOR INSTALLING AR- MAFLEX TUFFCOAT Cutting Template for t-pieces and segmented bends Brush with short, firm bristles Knives (three knife sets including sharpening stone or ceramic knives are available) Armaflex Tuffcoat mastic & mastic gun (foodsafe version available) Scissors for cutting Armaflex tape Smooth spatula for smoothing down covering THE CORRECT USE OF ARMAFLEX ADHESIVE Armaflex Adhesive 520 Armaflex Adhesive 520 has been specially developed to bond Armaflex materials. It joins the surfaces reliably and safely at medium temperatures of up to +105ºC. The bond is resistant to weathering and aging. PREPARING FOR WORK Check condition of Armaflex Adhesive. Cans of Armaflex Adhesive should have been stored in a cool environment wherever possible. Cans must also have been kept free from frost. Damage due to frost can be reversed by storing in warm conditions, or for immediate use by placing the can into a bucket of hot water. Shelf life approx. 1 year. 1. Where installation surfaces are soiled with dust, dirt, oil or water all of these contaminants must be removed and, where applicable, cleaned with Armaflex Cleaner before starting work. In addition all surfaces to be joined must be dry before gluing begins. 2. Pay close attention to the installation instructions on the adhesive can. Use small cans during work so that the adhesive does not thicken too quickly. Refill from larger cans when necessary and keep closed when not in use to avoid thickening 3. Plant equipment must not be in operation during the installation process! 4. Do not use adhesive under 0 C. If the adhesive is too cold it can be warmed in a bucket of hot water. At temperatures below 5 C, condensation can appear on the surfaces to be glued or the adhesive film. If this occurs materials become difficult to bond. Check whether this has happened by applying absorbent paper. When working in areas with a high atmospheric humidity and high temperatures see Hot Climates page 9 of this manual. Safe edge craft knife Sharpening stone Armaflex 520 adhesive Armaflex Tuffcoat tape (white or black) Sharpened pipe ends for the most common pipe diameters Gluemaster & brushes Armaflex Cleaner 5. Stir adhesive well after opening. If left to stand, heavier components in the adhesive may settle in the bottom of the can. These must be mixed thoroughly before use in order to effectively activate the adhesive. STEEL PIPES Check that the adhesive will adhere to any rust-inhibiting primer that has been used to protect steel pipes. Armaflex adhesive may not adhere to asphalt, bitumen, red-lead or cement surfaces. 2

3 1 - General >> Working with Armaflex Tuffcoat APPLICATION MANUAL APPLICATION 1. Use a brush with short, stiff bristles and keep clean. For larger projects the Armaflex Gluemaster is recommended to speed up application times. 2. Apply Armaflex adhesive thinly and evenly onto both surfaces to be glued. 3. The tack time for Armaflex 520 adhesive ranges between 3 and 10 min. The time will vary according to the grade, ambient temperature and relative humidity. Avoid open times (1) in excess of 20 min. (1) The open time is defined as the period between first applying adhesive and finally closing together the joint, seams or surfaces. 4. Allow the adhesive to tack-dry. The correct initial drying time may be determined by the fingernailtest : touch the surface with a fingernail, if the fingernail does not adhere to the surface and the surface itself does not feel tacky the seam may be closed. The maximum adhesive force will be obtained when two tack dry surfaces are brought together. 5. The glued surfaces should be pressed together, do not stretch. Do not leave the glued seams on top and always turn the glued seams away from the sun in external locations. 6. When gluing joins under compression, with no gaps present, the wet adhesive method should be applied. Pull the seam apart slightly and apply Armaflex adhesive thinly and evenly with the brush to both surfaces and press together. No open time is needed in this case. 7. Use Armaflex Cleaner to clean your tools, contaminated metal surfaces and surfaces which have had talc applied. 8. Curing time for Adhesive 520: 36 hours. Note: Do not mix Armaflex cleaner with Armaflex adhesive to thin it out - warm it. WET SEALING OF BUTT JOINTS 3. For the final wet sealing of the tube, pull the compressed butt joint apart with a finger and apply a thin even film of adhesive to the two butt joint edges with a small brush. 4. Apply firm and even pressure to the glued joint using the fingers and thumbs to finish. Note: It is highly recommended to follow the same procedures for hot piping lines located externally. OUTDOOR USE OF AMRAFLEX TUFFCOAT Whenever used externally all Armaflex Tuffcoat seams should be sealed with 25mm wide Armaflex Tuffcoat tape (12.5mm wide tape for segmented bends). Elbows and t-pieces should be sealed with Armaflex Tuffcoat mastic. All seams should be positioned on the underside of the pipe with tape ovelaps facing downwards to minimise exposure to water. ADVICE FOR INSULATING REFRIGERATION AND A/C EQUIPMENT Attach each end of the Armaflex Tuffcoat tube to the pipe with Armaflex adhesive, and make sure the adhesive joints are firm at critical points such as T- sections, elbows, supports, etc. All connected items of equipment shall be insulated with equal thickness where practical. Never insulate chilled water lines or refrigeration equipment if the sections to be insulated are too close together. An air gap of at least 25mm should be present between the insulated chilled water line surfaces to prevent sweating. General >> Working with Armaflex Tuffcoat 25 mm 1. On all cold lines and all piping equipment in an external location, fix Armaflex Tuffcoat tube ends down to the piping surface with Armaflex adhesive. 2. The width of the adhesive bonding should equal the insulation thickness as a minimum. Armaflex Tuffcoat should not contribute to corrosion, however due to the presence of chloride ions in the normal building environment, it remains best 3

4 APPLICATION MANUAL 1 - General >> Working with Armaflex Tuffcoat General >> Working with Armaflex Tuffcoat practice to pre-coat the steel surface to be insulated using either aluminium foil or special paints before applying the Armaflex Tuffcoat. INSULATING STAINLESS STEEL PIPES BS 5970 gives a number of specific recommendations when insulating stainless steel pipes. These installation practices greatly reduce the risk of stress corrosion cracking. All Armacell recommendations for installation on stainless steel pipework are intended to be in compliance with the procedure laid out in BS CUTTING ARMAFLEX TUFFCOAT TUBES Use a sharp knife. Keep knife at a low angle when slitting tube INSULATING NEW PIPEWORK WITH SLEEVE-ON-TECHNIQUE Standard Armaflex tubes can typically be pushed around bends. The stiffer Tuffcoat covering material makes this difficult on all but the most gradual of bends however, meaning that segmented bends need to be made. If the insulation kinks, or cannot be pushed over, then it should be cut into segments to fit (see pages 5 & 6). Note: Do not attempt to pull the Armaflex tube along the pipe as this may cause the insulation to tear. Insulation for straight pipework lengths can simply be pushed on. 1cm of Armaflex is left exposed at each end of the Armaflex Tuffcoat tubes to aid compression sealing at butt joints. The joins should then be covered with Armaflex Tuffcoat tape cut to fit around the outer diameter of the insulation with a slight overlap. The tape should be smoothed down with a plastic card / spatula tool to remove any bubbles. INSULATING EXISTING PIPEWORK WITH SNAP-ON-TECHNIQUE Use sharpened off-cuts of pipes to make holes for T- pieces. 1. With a sharp knife, slit the flat part of the unslit Armaflex Tuffcoat tube along the entire length using an Armaflex slitting knife tool. 2. Place the slit tube onto the clean pipe; apply Armaflex adhesive to the two cut edges with a thin even film of adhesive using a short bristle brush. Apply the adhesive at 200mm intervals along the tube length. Always cut on the flat side of tubes. 4

5 2 - Pipes & Fittings >> Using Armaflex Tuffcoat Tubes APPLICATION MANUAL BEND WITH 90 ANGLE USING ARMAFLEX TUFFCOAT TUBE Allow the adhesive to touch dry, test with the fingernail. 4. Free the seams from the pipe where applicable, line the edges together and press the seam detail with firm even pressure to finish. Seal the two ends first before working inwards to the middle of the tube. 5. Once the seams are glued together peel back the self-adhesive covering sheet and fix down the un-adhered section of Tuffcoat covering. Apply Armaflex Tuffcoat tape to the join and smooth out any bubbles with a spatula / plastic card. 6. Joins should be sealed using Armaflex Tuffcoat tape. Mastic is required for elbows and t-pieces outdoors and for all seams in pressurised washing areas to prevent water ingress. A food safe mastic is available where required. Use a bead of 10mm wide by 3mm thick. 7. In general, the application of the mastic should not be carried out when the ambient temperature is below +5 C or the relative humidity is higher than 80%. 8. For quantities of tape and mastic required please see table on p.11. USING THE ARMAFLEX TEMPLATE The fabrication of bends and tees using Armaflex Tuffcoat tube requires the tubes to be cut to different angles. In order to make this process quick and easy, the Armaflex template is available. 1. Place a copy of the Armaflex template face up on a table or worktop. Note: Yellow lines indicate where cuts are to be made. For correct angle measurements please use the Armaflex template.

7 2 - Pipes & Fittings >> Using Armaflex Tuffcoat Tubes APPLICATION MANUAL Applying ARMAFLEX TUFFCOAT Mastics INSULATING PIPE SUPPORTS 1. Ensure all underlying fixing seams/joints are fully bonded and secured using Armaflex adhesive and check that all seams and joints are clean, dry and free from contamination before applying the mastic. 2. For all seams and joints allowance should be made for a minimum 10 mm wide and 3 mm thick mastic beading to be applied. 3. Smooth the mastic with the use of a mastic spoon. The finish of the mastic can be enhanced by masking off 5 mm either side of the seams and joints, prior to the application of the mastic. Proceed to remove the masking tape while the mastic is still wet. 4. In general, the application of the mastic should not be carried out when the ambient temperature is below +5 C or the relative humidity is higher than 80%. Where Armaflex Tuffcoat is installed, the use of Armafix pipe supports are the preferred solution for the prevention of ice and condensation on cold installations. However, when Armafix pipe supports are not selected, the following instructions are imperative: Ensure that the Armaflex is fitted tight to the support, with no air gaps present and vapour sealed with Armaflex adhesive. Install Armaflex self adhesive tape to the butt joint where the Armaflex and the support meet. Ensure the surface of the butt joint is free from dust before installing the Armaflex tape. INSTALLING ARMAFIX INSULATED PIPE SUP- PORTS Armafix pipe supports are sections of Armaflex with load bearing PUR/PIR inserts and an aluminium outer shell cladding. Note: Select the correctly dimensioned Armafix pipe support (min. insulation thickness of tube). Use a standard pipe support bracket around the outer aluminium shells. Pipes & Fittings >> Using Armaflex Tuffcoat Tubes Install the Armaflex insulation on either side of the Armafix pipe support. Wet seal the butt joints with the Armafix pipe support using Armaflex adhesive. Note: Ensure that the pipe insulation is installed under slight compression. 7

8 APPLICATION MANUAL 3 - Pipes & Fittings >> Insulating Pipe Supports INSULATING OVER (ENCAPSULATING) PIPE SUPPORTS INSULATING PIPE UNIONS USING ARMAFLEX TUFFCOAT TUBE On cold lines pipe supports must be insulated to prevent condensation. If no insulated pipe supports have been specified the following approach should be followed as a minimum precaution. Note: It is best practice to always have an insulated pipe support such as Armafix installed. Pipe unions can be insulated in several ways using Armaflex Tuffcoat tube. This method does not require a separate oversized tube and can be implemented using Armaflex Tuffcoat tube of the same dimensions as used on the linear pipe run. Pipes & Fittings >> Insulating Pipe Supports 1. Install the Armaflex Tuffcoat as close to the fixing bracket as possible. Seal the ends of the tube to the pipe with Armaflex 520 adhesive. 2. With a large off-cut of Armaflex Tuffcoat tube, core out a small hole to allow for the oil thread support of the bracket and slit with a small sharp knife along the flat face of the tube. 1. Install the Armaflex Tuffcoat as close to the union as possible. Seal the ends of the tube to the pipe with Armaflex 520 Adhesive. 2. Slit a large off-cut of Armaflex Tuffcoat tube (minimum length at least 5 times the pipe diameter) with a small sharp knife along the flat face of the tube and open the tube into a cover. 3. Place the Armaflex Tuffcoat cover over the support area, mark and cut the true circumference of the cover. 8 Fix and vapour seal all seams and joints in and around the attached insulation using Armaflex adhesive and cover with Tuffcoat tape (elbows and t-pieces outdoors and all seams in washdown areas should be sealed with Tuffcoat mastic). Note: Armaflex 3mm Insulating self adhesive tape can be applied mm along the attached oil thread support. 3. Place the Armaflex Tuffcoat cover over the union, mark and cut the true circumference of the cover. Fix and vapour seal all seams and joints in and around the attached insulation using Armaflex 520 adhesive. Cover seams with Tuffcoat tape.

9 4 - Additional Information >> Use of Adhesive in Hot & Humid Environments, Ductwork APPLICATION MANUAL USE OF ADHESIVE IN APPLICATIONS INVOLV- ING HOT AND HUMID ENVIRONMENTS High atmospheric humidities and temperatures lead to faster evaporation of the solvent in Armaflex adhesive. This means that a film of moisture may appear on the surface of the adhesive. Consequently the reliability of the adhesive seam cannot be assured since the surfaces to be joined may not bond together. Under these conditions, the following points may be observed as an alternative to our installation instructions: Apply Armaflex adhesive as normal in a thin uniform film on both surfaces. Unlike normal bonding, the surfaces to be glued should be held together under pressure whilst wet. Note: Due to the shorter curing time adhesive can only be applied to a limited area at one time. Depending on the atmospheric humidity, temperature, material thickness and practical installation condition we recommend a tube length of around 1m as a reference figure. To prevent possible tensions within the material and the enclosed solvent opening the seam, seams should be held in place immediately after bonding with Armaflex Tuffcoat tape across the glued seam every 20 cm or so. Applying ArmaFLEX TUFFCOAT Outdoors (Water-Shed - Roof Tile Effect) All seams and joint details should be arranged so as to eliminate any direct paths which may allow water ingression into the insulation system. On straight-line applications, the main fixing seams shall be positioned and tapes applied with the overlaps facing downward as shown. Note: Particular attention is required on fittings such as elbows and t-pieces. MEASURE SURFACE DIMENSIONS FOR INSULATING RECTANGULAR DUCTS Measure surface dimensions and cut Armaflex Tuffcoat sheet to size. Note: Add 5mm so that material is fitted under compression. b 2a c 3 a 1 2b a = width of duct + 5mm b = height of duct + 5mm + thickness of insulation c = width of duct + 5mm + 2x thickness of insulation INSULATING RECTANGULAR DUCTS WITH ARMAFLEX SHEET Clean all surfaces using Armaflex cleaner to remove grease, oil, dirt etc. and cut sheets to size Spread a thin film of adhesive onto the metal surface and then onto the Armaflex Tuffcoat sheet. A non-foam roller or Armaflex Gluemaster can be used to speed up the adhesive application. When the adhesive is tack dry (fingernail test) place Armaflex Tuffcoat sheet in position and press firmly to achieve a good bond. Continue, applying Armaflex adhesive 520 to both surfaces, including the Armaflex edge, and allow to tack dry before pressing firmly into position. Note: Remember to roll the sheet down into position along the insulated edges. Insulate acc. to drawing, this is especially important for external duct work.

12 The Armaflex Assurance System The Armaflex Assurance System - your peace-of-mind assurance that Armaflex is made to the strictest quality, technical performance and environmentally friendly standards. Prevents Moisture Permeation Multi-layered closed wall cells provide a built-in vapour barrier which can t be compromised by surface punctures or rips - this ensures the vapour barrier stays working for the lifetime of the insulation system. Provides Long-Term Thermal Performance Non-wicking - No transmission of water vapour is possible through the insulation due to the closed cell nature of Armaflex. Moisture will not migrate through professionally installed Armaflex. Inhibits Growth of Mould Minimises moisture permeation, the first requirement for mould growth Minimises the second requirement: No cellulosic vapour jacket, and the smooth surface doesn t trap dust Formaldehyde-Free Ensures that Armaflex is a low-emitting product. It is also low VOC. Support Requirements of Health & IAQ (Indoor-Air-Quality) Dust and Fibre-Free Will not emit any particles or fibres - even when cut into shapes and fittings No outgassing - CFC & HCFC free manufacturing process application manual >> ARMAFLEX TUFFCOAT Long-Term Durability No fragile water vapour barrier - The built-in vapour barrier can t be damaged during installation or over the lifetime of the insulation. Avoids Thermal Bridging Armaflex is a seamless insulation system - these same technical properties provide a secure system. Long-Term Energy Efficiency By minimising the ingress of water vapour into the insulation the multi-layered cells in Armaflex prevent the thermal conductivity from rising.
