Install pipe insulation by slitting tubular sections and applying onto piping or tubing. Alternately, whenever possible, slide unslit sections over the open ends of piping or tubing. All seams and butt ends shall be adhered and sealed using K-Flex Contact Adhesive. When using Insul-Lock Seam- Seal, only the butt ends shall be adhered using K-Flex Contact Adhesive. 2. Insulation shall be pushed onto the pipe, never pulled. Stretching of insulation may result in open seams and joints. 3. Tape the ends of the copper tubing before slipping Insul-Tube insulation over the new pipes to prevent dust from entering the pipe. 4. All edges shall be clean cut. Rough or jagged edges shall not be permitted. Proper tools such as sharp, non-serrated knives must be used. 5. On cold piping, insulation shall be adhered directly to the piping at the high end of the run using a two-inch strip of K-Flex Contact Adhesive on the ID of the insulation and on the pipe. All exposed end cuts of the insulation shall be coated with K-Flex Contact Adhesive. All penetrations through the insulation and termination points must be adhered to the substrate to prevent condensation migration.

6 6. Sheet insulations shall be used on all pipes larger than 8 IPS. Insulation shall not be stretched around the pipe. On pipes larger than 12 IPS, adhere insulation directly to the pipe on the lower 1/3 of the pipe. On pipes greater than 24 IPS, complete adhesion is recommended. 7. Seams shall be staggered when applying multiple layers of insulation. b) Fittings 1. All fittings shall be insulated with the same insulation thickness as the adjacent piping. All seams and mitered joints shall be adhered with K-Flex Contact Adhesive. Fittings can be specified as factory fabricated (K-Fit prefabricated fittings) or field fabricated. Screwed fittings shall be sleeved and adhered with a minimum 1 overlap onto the adjacent insulation. c) Pipe Hangers 1. K-Flex 360 Insulated Pipe Supports should be used at all pipe hanger locations to support the piping system with high-density inserts with sufficient compressive strength to prevent the insulation from compressing. The pipe support insulation shall be elastomeric foam with the same or greater thickness than the pipe insulation. All joints shall be sealed with K-Flex Contact Adhesive. 2. Standard and Split Hangers Piping supported by ring hangers shall have hangers insulated with the same insulation thickness as the adjacent pipe. All seams and butt ends shall be sealed with K- Flex Contact Adhesive. Ring hangers may be sleeved using oversized tubular insulation. On cold piping, insulation shall extend up the hanger rod a distance equal to four times the insulation thickness. Insulation tape may be used to a thickness equal to the adjacent insulation thickness. 3. Clevis hangers or other pipe support systems Saddles shall be installed under all insulated lines at unistrut clamps, clevis hangers, or locations where the hanger may move due to movement in the piping (expamsion and contraction). K-Flex 360 Insulated Pipe Hangers should be used to prevent compression of the insulation due to the weight of the pipe system. An alternative to insulated pipe supports is to use wooden dowels or blocks of a thickness equal to the insulation inserted and adhered to the insulation between the pipe and the saddle for support. For continuous insulation protection, it is recommended to use hanger sizes equal to the outer diameter of the pipe plus insulation thickness. d) Exposed Outdoor Piping 1. All outdoor exposed piping shall be painted with two coats of K-Flex 374 Protective Coating. Prior to applying the Finish, the insulation shall be wiped clean with denatured alcohol. The Finish shall not be tinted. A long-term, low maintenance alternative to the use of a protective coating is K-Flex Clad AL, K-Flex Clad WT or K-Flex Clad WT NS. 2. All outdoor exposed piping shall have the seams located on the lower half of the pipe. e) Piping Insulation Thickness Schedule NOTE: This K-Flex insulation wall thickness schedule is based on K-Flex Normal Design Conditions of 85 F and 70% RH. Deviations from these design conditions may change the K-Flex insulation thickness requirements. Consult local energy code requirements for minimum insulation thickness.

If the surface is not clean, it should be wiped down with a cleaner such as denatured alcohol to ensure good adhesion. Use of Sheet with PSA (pressure sensitive adhesive) is an acceptable option. 3. The duct shall be insulated using fabricated pieces, not wrapped. The sheet shall be fabricated such that the top sheet shall overlap the side sheets and the side sheets overlap the bottom sheet to form a water shed, thus insuring water will not penetrate the seam. 4. Duct seams shall be insulated with the same insulation thickness as the duct itself. 5. The ductwork must be pitched (as illustrated by the system designer) to prevent ponding of water. 6. Insulation seams shall be staggered when applying multiple layers of insulation. 7. Adhesive shall be applied to the sheet metal with a 90% minimum coverage. All rips and tears shall be repaired. 8. Transverse joints shall be firmly butted with no gaps and coated with adhesive. Longitudinal corner joints shall be overlapped and compressed. Note: All ductwork shall be tested for air tightness and sealed as necessary prior to installation of duct covering. The use of mechanical attachment for duct covering is optional. b) Round Ductwork: General Recommendations 1. Insul-Sheet, Insul-Sheet with PSA, K-Flex Clad AL, K-Flex Clad WT insulation shall be used on all round ducts as a duct cover / wrap. Insulation shall be wrapped, not stretched, around the duct. On duct wrap for horizontal ductwork larger than 12 in diameter, the insulation shall be adhered to the duct surface on the lower one third. All seams shall be located on the lower half of any round ductwork. K-Flex Duct Liner Gray shall be used on lined ducts and shall be adhered 100 percent using approved Contact Adhesive.

All duct wrap insulation on ductwork installed outdoors shall be adhered 100 percent using approved Contact Adhesive. 2. Applications requiring protection from the degradation effects of UV rays can be protected by applying 2 coats of K-Flex 374 Protective Coating. To ensure good adhesion, the temperature should be above 50 F (10 C) during the application and drying. Four hours should be allowed between coats for drying. Periodic refinishing may be required to prolong the usefulness of the insulation. Note: If the insulation surface is not clean, it should be wiped down with a cleaner such as denatured alcohol to insure good adhesion. 3. Applications requiring water proofing will require the application of a weather barrier mastic (i.e., as supplied by Childers, Fosters, Mon-Eco, etc.) and should be applied according to the manufacturer s recommendations. a) Apply a tack coat of mastic similar to Childers CP-9 water-based coating or equal, at the rate of 50 sq. ft. per gallon to the insulation. Insulation must be clean and dry. b) Lay in a glass reinforcing membrane. c) Finish with a coat of mastic (i.e. Childers CP-9 or equal) at a rate of 25 sq. ft. per gallon. Let dry. 4. As an alternative to A and B above, K-Flex Clad AL or Clad WT may be used. All Joints shall be taped using approved tape. Edges of tape shall be sealed with high quality silicone caulking in applications where waterproofing is required. Additional Notes:

9 a) Flat ducts in a horizontal plane must be pitched (as illustrated by system designer) to shed water. There must be no areas of ponding water. b) The coatings should have a minimum of 24 hours to dry before being exposed to rain. c) The coating must not be exposed to freezing temperatures during storage or before it dries. When freezing temperatures are encountered, solvent based mastic must be used. Refer to the coating manufacturers application recommendations. d) All glass cloth must be overlapped 2 inches minimum. Reinforcing membrane should be either 5 x 5 or 10 x 10 weave to insure the mastic can easily bond to itself through mesh openings d) Ductwork Insulation Thickness Recommendations Note: Insulation recommendations are based on data generated using K-Flex USA Elastomeric Insulation Products. Design criteria used to prevent condensation were for normal conditions of 85 F (29 C) and 70% Relative Humidity, unless noted otherwise. More severe conditions would require additional insulation. Insulation thicknesses must comply with all applicable code provisions. Design criteria used for energy savings on hot systems were based on typical energy costs and operating conditions. Energy calculations were based on thickness recommendations which would typically achieve between BTU loss per hour per square foot. These may not reflect actual conditions and should be verified for each application. ASHRAE 90.1 and most state and local codes determine thickness recommendations (min. R value) based on climate zone and location of the duct ie. Exterior, unconditioned space attic etc. Minimum R values will range from 1.9 to 8.0 depending on the climate zone and the location of the duct. 1.
