Please note: For installing self adhering SA Armaflex sheets and rolls, refer to p.19. Installation: 4.b. Using Armaflex sheet insulation on pipes Application to pipes 1. Apply Armaflex Sheet Insulation on pipes larger than 5″ IPS. Cut the sheet insulation to proper width, permitting it to fit loosely without stretching around the pipe. (See pgs 11-12.) The fabrication must be done at the job site, at the same ambient conditions as the application. 2. Brush-coat both surfaces of the lengthwise seam with 520 or 520 BLV Adhesive. Allow the adhesive to dry until tacky to the touch under slight pressure before joining surfaces. Wrap the sheet around the pipe, and seal the seam by pressing the surfaces firmly together. Join butt joints between individual sections using 520 or 520 BLV Adhesive. On horizontal pipes larger than 12″ IPS, adhere insulation on lower one-third. ting cover, the complete fitting cover is formed by adhering two halves together at the long outer arc. Coat both surfaces with 520 or 520 BLV Adhesive. Allow the adhesive to dry until dry to the touch but tacky under slight pressure before joining surfaces. Then seal the seam by pressing the surfaces firmly together throughout. To do this, press the adhesive joint on the rough side and then snap the cover inside out and press the joint on the smooth skin side. (The tee template is a symmetrical half, but, in this case, both halves are laid out together to form the complete outline of the fitting cover.) 1 3 2 4 Application to fittings 3. Fitting covers are easily made, using templates designed specially for screwed fittings 2″, 21/2″ and 3″ and long-radius weld fittings from 3″ to 10″ IPS. (See size chart, pg 11.) Note: Templates should be traced on stiff paper, sheet metal or hardboard and cut out to make reusable patterns. 4. Since each template for 45˚ and 90˚ ells is shown as a symmetrical half of the full fit- 9 Please note: For installing self adhering SA Armaflex sheets and rolls, refer to p.19. Installation: 5. Snap the formed cover in place over the fitting. Adhere the mating surfaces of the inner arc joint with 520 or 520 BLV Adhesive. Join the straight pipe covering to the fitting cover, making sure to coat both the pipe-section butt surface and the fitting-cover butt surface. Note: On screwed fittings, select the proper template from section 4.b.1., page 11. Notice that the screwed fitting cover templates allow for the 1″ minimum overlap on the straight pipe next to the fitting. Remember to cement this 1″ overlap with 520 or 520 BLV Adhesive by forcing the brush between the two surfaces. 6 5 TEMPLATE FOR VICTAULIC COUPLING 45° ELL 6.

Armaflex sheet on flanged valve fitting covers These instructions are meant to serve as a guide for insulating flanged valves with Armaflex. Because of the variety in shape and design of flanged valves, some modifications to these instructions may be necessary. At this time, the Armaflex donuts at the ends of the fitting should be sealed to the fitting body insulation with 520 Adhesive. ▲ 2. Use scrap strips of Armaflex Sheet to build the body of the valve out until it is the same dimension as the OD of the flanges. Adhere the Armaflex strips directly to the valve body, using 520 or 520 BLV Adhesive. ▲ 1. Cut Armaflex donuts the same diameter as the flanges, and install at pipe/flange and valve stem areas. 5. The Armaflex Sheet, cut out as shown in Figure 4, is installed around the valve body and the joint adhered with 520 Adhesive. This is accomplished by running the adhesive brush between the outer circumference of the Armaflex donut and the inside of the ends of the body insulation (a wet joint). ▲ Armaflex donuts (Same OD as flange) ▲ 1 3.

The radius of the arc is equal to Y. These arcs are connected with straight lines to give a smooth scalloped edge (see Figure 6B). The scalloped edge of the insulation must be undercut (beveled) to correctly meet the body insulation. ▲ ▲ Bonnet area C—The overall length is determined by wrapping a strip of Armaflex Sheet around the bonnet flange (do not stretch) and marking where the ends meet. L1—This distance is obtained by measuring from the outer surface of the Armaflex donut to the approximate middle of the valve body insulation. L2—This distance is obtained by measuring from the outer surface of the Armaflex donut to the closest surface of the valve body insulation. Y—is the difference between L1 and L2. ▲ ▲ L1 Figure 6A.

Installation: Armaflex sheet on metal ductwork The preferred method for square and rectangular ducts is to cut and fit the sheets, using full coverage of Armaflex 520 or 520 BLV Adhesive to adhere the insulation. 1. Measure—Sheets should be sized with the following application sequence in mind. Cut the bottom piece first, making it the same width as the duct. Then cut the two side pieces, so that they extend down over the edges of the bottom insulation; keep top edges flush with the top of the duct. The top insulation should be sized so that it extends over the side insulations. The fabrication must be done at the job site, at the same ambient conditions as the application. 2. Cut—A sharp knife and a straightedge are the only tools required. Armaflex Sheet cuts cleanly. 3. Apply Adhesive—First brushor roller-coat 520 or 520 BLV Adhesive on the metal duct surface. Then coat the back side of the Armaflex Sheet, leaving a 1/2″-wide uncoated border at butt-edge seams. Allow the adhesive to dry to the touch but still tacky under slight pressure before joining surfaces. in this position, and spot-adhere it in the center. Compress the butt edges into place for a tight joint with adjoining sheets. Then bond the remainder of the sheet by pressing it firmly into place. A small hand roller will help apply pressure. 5. Adhere Joints—Spread the joint, and with a small brush, apply 520 or 520 BLV Adhesive to both butt edges. Do not flood joint with adhesive. Align carefully for good appearance, and apply pressure to joint. 6. Standing Seams—These can be insulated with strips of Armaflex Sheet, generally cut from scrap. 8. Apply WB Armaflex Finish— Two coats of WB Armaflex Finish, a white water-based latex enamel coating, are all that is required to provide a protective finish for outdoor installations. WB Armaflex Finish can be brush- or rollerapplied. 1 2 3 4 5 6 7 8 4. Bond—Position the sheet so that it overlaps the edges of previously installed sheet or sheets by 1/8″. Hold the sheet 16 7. Alternate Method—Standing seams can also be insulated with half sections of Armaflex Pipe Insulation, corresponding in thickness to the sheet used on the duct surface. Ends should be miter-cut to insure tight fit when bonded. Please note: For installing self adhering SA Armaflex sheets and rolls, refer to p.19. Installation: Flexible ArmaTuff Plus, ArmaTuff White or ArmaTuff Silver can be used for all exterior applications. They are practical also for use on exterior ducts, tanks, vessels, large pipes and fittings. The material provides a durable, tough and maintenance-free surface. The material is resistant to UV, ozone, acid rain and most industrial pollutants. No painting is required. The recommended temperature usage range for ArmaTuff is -70°F to 180°F (-57°C to 82°C). The closed cell structure of ArmaTuff insulation effectively retards the flow of water vapor, and it is considered a low transmittance vapor retarder. ArmaTuff does not require additional vapor retarder. The white surface reflects heat to reduce energy load. ArmaTuff is designed for installation in above ground applications. Armaflex insulation products must be installed according to Installation of Armaflex Insulations brochure. Proper installation is required to assure Armaflex insulation performance. Applying Non-Self Adhering ArmaTuff Sheets 1. Always prepare surface by cleaning with denatured alcohol. ArmaTuff is installed using Armaflex 520 or 520 BLV adhesive or with pre-applied pressure sensitive adhesive (PSA). For application to large, flat or curved 2. Insulate sides first.
