TRYMER® 2000 XP

ITW Insulation Systems has the right trio of products for commercialbuilding chilled water and hot water pipe insulation applications. When properly designed and installed, chilled water, hot water and dual temperature pipe insulation systems from ITW Insulation Systems help manage building temperature and humidity levels for optimum comfort while simultaneously reducing energy usage and costs. Without adequate insulation, the thousands of feet of chilled and/or hot water piping can also be a source of costly problems associated with moisture, mold, poor air quality and increased energy usage. Choosing the right pipe insulation can go a long way toward ensuring continuous operation, optimum service life and long-term system owner satisfaction.

The 1-2-3 Solution: • TRYMER® 2000 XP - Polyisocyanurate Insulation • TRYMER® Green - Phenolic Insulation • SARAN™ CX Film and Tape - Vapor Retarder

For commercial building chilled water pipe insulation systems, the combination of TRYMER® Green Phenolic Insulation in the plenums and TRYMER® PIR everywhere else provides a “One-Two punch” that will exceed all energy efficiency and fire safety requirements with an insulation system that is cost effective and resists water and water vapor. Applying SARAN™ CX Vapor Retarder Film and Tape to both the TRYMER® Green Phenolic Insulation and the TRYMER® PIR insulations makes an already unbeatable system even better by improving the water vapor resistance without the presence of an ASJ product that is based on thin aluminum foil with paper backing.

TRYMER® GREEN

TRYMER® Green Phenolic Insulation offers the lowest thermal conductivity of any standard material and combines this with excellent flammability performance, closed-cell, and good water and water vapor resistance. These properties make TRYMER® Green Phenolic Insulation the ideal material for use as pipe insulation on chilled water lines operating in the air plenums of commercial buildings where flammability is the greatest concern but energy efficiency is still important and governed by codes.

At any thickness that might be needed, the flammability performance of TRYMER® Green Phenolic Insulation meets the strict ASTM E84 25/50 flame spread/smoke developed requirement common in many buildings codes for pipe insulation located inside of plemums. Its unparalleled thermal conductivity allows TRYMER® Green Phenolic Insulation to be used at lower thickness than other insulation materials while still meeting and usually exceeding the energy efficiency requirements.

Managing moisture is a continuous challenge in all cold pipe insulation systems, including chilled water applications. This is especially true in high-humidity environments. Because no insulation material is completely immune to the destructive effects of water vapor drive, a high performance vapor retarder is the insulation system’s first line of defense against water and water vapor intrusion. The thermal conductivity of water is much worse than that of any insulation material. If moisture penetrates the insulation, it will: • raise its thermal conductivity • reduce its ability to prevent heat loss • add weight to the line • increase the likelihood of pipe corrosion • lead to condensation on the outer surface of the insulation system • create an environment conducive to fungal growth.

A high quality vapor retarder applied to the outer surface of the insulation keeps water and water vapor from entering the pipe insulation system and will help prevent all of the above mentioned problems.

SARAN™ CX Vapor Retarder Film and Tape stand guard against this moisture assault, enabling TRYMER® 2000 XP and TRYMER® Green insulation

to perform at optimum levels. SARAN™ CX Vapor Retarder Film is either factory or field-applied to straight lengths of pipe insulation. Factory application of SARAN™ CX Film saves installation time on the job site. At butt joints and around elbow and fitting insulation, SARAN™ CX Tape provides a tight, water resistant seal, protecting the weakest links in the system.

A TRYMER®/SARAN™ system is much stronger and more impermeable to water and water vapor than fibrous insulation wrapped with all-service jacket (ASJ). Consider this: ASJ achieves its water vapor resistance from a very thin and delicate layer of aluminum foil that can be easily damaged or pin-holed by wrinkling, folding, and even installation. Any pin-holes in the ASJ foil provide easy entry of moisture through the paper backing of the ASJ and the fibrous insulation provides no resistance to the intrusion of water vapor. Contrast this with SARAN™ CX Vapor Retarder Film and Tape which are made of strong PVDC polymer and are resistant to damage during installation and system operation.

SARAN™ CXThe First Line of Defense Against Moisture

TRYMER® Green insulation has a very low k-factor of 0.15 Btu•in/hr•ft²•°F at 75°F mean temperature (0.022 W/m•°C at 24°C)

k-factor You Can Count OnThermal conductivity (k-factor) is a key consideration in determining which pipe insulation is best for your application. Because of their low k-factor, TRYMER® Green and TRYMER® 2000 XP insulations provide enhanced insulation performance with less product thickness. This allows thinner cross sections of insulation to be specified throughout the system. System owners will appreciate the cost savings associated with less insulation, as well as the need for less accessory materials such as sealant, vapor retarders, and jacketing. And when running series of lines with close spacing between each pipe, or in challenging applications such as small confined spaces, e.g., in medical facilities, the superior k-Factor of TRYMER® insulations (see chart) allows you to plan tighter pipe spacing.

Long-Lasting Moisture-ResistantIt’s a fact: Insulation products that resist moisture last longer. Water penetrating an insulation system can result in loss of thermal efficiency, condensation, icing, corrosion and even physical destruction of the insulation system. As a closed-cell, non-fibrous insulation,TRYMER® products provide resistance to moisture. Their low permeability rating also means that they resist the vapor drive that occurs when pipe operating temperatures cycle below ambient.

In the event the primary vapor retarder fails, the low moisture vapor permeability and low water absorption of TRYMER® insulation products provide a second line of defense against moisture entry. That can buy the system owner valuable time to repair the system, helping to reduce maintenance and replacement costs.

Strong and Durable

Chilled water and hot water pipe insulation can be subjected to harsh treatment during both installation and operation. That’s why selecting materials that aren’t delicate or prone to breakage is critical. TRYMER® 2000 XP and TRYMER® Green insulations are resistant to damage on even the most rugged job sites and under the most demanding operating conditions. They can be installed quickly and easily without abrading installer fingers, or producing glass fibers or odors during installation or operation.

Other insulations on the market cannot deliver that level of durability. With significantly higher friability than TRYMER® insulation, cellular glass insulation is much more prone to breakage and damage during installation and use.

ITW’s technical staff and indepen dent testing groups have compiled data on the thermal and physical characteristics of various insulation materials most frequently specified for mechanical insulation systems. The four graphs to the right show some of these results.

TRYMER® 2000 XP and TRYMER® Green Insulations have low water absorption, comparable to other closed-cell insulation materials and vastly better than the water absorption of fibrous insulations like glass fiber or mineral wool. When comparing claimed water absorption values such as those shown in Table 4 to the right, it is crucial to understand the duration of immersion and the type of water exposure. Durations can range from 2 to 96 hours. Exposure for closed cell products involves immersion in liquid water while the exposure for fibrous insulations is just to humid air. Note that with 96 hour exposure to just humid air, fibrous insulation materials absorb up to 0.5% water. Compare this to TRYMER® 2000 XP and TRYMER® Green Insulations which are tested via complete immersion in liquid water for 2-24 hours yet only absorb 0.5-0.7% water. Note also that the water absorption results for TRYMER® 2000 XP are a little higher than the other closed-cell materials but the TRYMER® 2000 XP is immersed in liquid water for 24 hrs compared to only a 2 hr immersion for the other closed-cell materials.

TRYMER® Green insulation has a very low k-factor of 0.15 Btu•in/hr•ft²•°F at 75°F mean temperature (0.022 W/m•°C at 24°C)

Fungal growth on and in building materials is a serious issue. Mold and mildew can damage the pipe insulation system you design – and your reputation.

Stained and moldy ceiling tiles are often the first indication that condensation is occurring on the exterior surface of pipe insulation. This can be caused by water intrusion into the insulation system, use of an inadequate vapor retarder, damage to the insulation system, too little insulation thickness, or harsher conditions than expected. According to the American Industrial

Hygiene Association, studies have shown that as much as 50 percent of microbial problems in buildings are not visible. Any problems with the large amount of chilled water piping in your commercial buildings can be a serious threat to your reputation and to your bottom-line. A properly designed, installed and maintained insulation system incorporating TRYMER® 2000 XP PIR insulation or TRYMER® Green Phenolic insulation and SARAN™ CX Vapor Retarder Film and Tape will help minimize the potential for moisture problems, which will help reduce opportunities for mold formation.

Mold: A Threat to Your Reputation

Fiberglass pipe insulation offers virtually zero resistance to water or water vapor, the entrance of which into the insulation can lead to mold formation and pipe corrosion.

The very thin and delicate foil layer in the ASJ vapor retarder typically used on glass fiber insulation is easily damaged which will allow water vapor and mold spores to enter the fibrous insulation. The paper backing on ASJ also readily absorbs water and can provide a nutrient source for mold growth.

Wet insulation not only can cause insulation inefficiencies leading to mold and mildew, but can also cause pipe corrosion which can dramatically shorten the life span of a chilled water or any piping system.
