TECHNICAL SPECIFICATIONS OF OUR PRODUCTSThis section describes the technical characteristics of ourproducts to enable an understanding of the quality aspects ofinsulation materials. Concepts such as closed cell structure,thermal conductivity, water vapor transmission and - in general- the technical features of our materials are explained asan introductory guide. There is also a detailed explanationof the different types of materials that we produce: pipe andsheet insulation, tapes and insulating supports, and insulationsystems.PAGE 15

PHYSICAL PROPERTIES PERFORMANCE CHARACTERISTICSCLOSED CELL STRUCTUREClosed cell elastomeric insulation products have comparative advantages over traditional opencell products made of wool or fiberglass, particularly in below ambient applications, including:- Stronger system integrity: Lower water vapor diffusion ensures long-term low thermalconductivity without the use of protective coatings/jacketing on indoor applications. Open cellproducts require a jacket that, if punctured, could cause the insulation system to fail.- Nonconnecting cell structure inherently resists mold and bacterial growth, because of an inabilityto spread within the structure.- Elastomeric composition creates excellent flexibility for easy installation.- Fiber-free formulation ensures that no particles or contaminants are released into the operatingenvironment during installation or operation.RESISTANT TO WATER VAPOR TRANSMISSIONWater vapor transmission rate refers to the steady water vapor flow through the area ofa body. Materials with a wvt of 0.10 perms-in or less are considered to be moisture vaporretarders as defined by ASHRAE and ASTM. Elastomeric products achieve this wvt valuewithout the addition of a jacket. Fibrous products require a jacket (concentrated vaporbarrier) to achieve this, but if the jacket is punctured or torn from mechanical abuse, thewvt value increases substantially, possibly resulting in system failure. In addition, moistureintrusion can result in the growth of mold and fungi on or in the material. Eliminationof moisture is a key to the elimination of mold. Because the thermal conductivity of wateris approximately 15 times higher than typical insulation, any absorption of water vaporcould reduce the insulation efficiency.NON-TOXIC PRODUCTSMany insulation materials are porous or fibrous where the presence of moisture and organicmatter allows the growth of bacteria, mold and fungi. K-FLEX USA products are resistant to thisand, as a result, contribute to the quality of the air that we breath. To ensure that our productsdo not emit VOCs (volatile organic compounds), we use RoHS-compliant ingredients and utilizestate-of-the-art production processes. K-FLEX USA products are GREENGUARD-certified as lowVOC materials, meeting the requirements of the “Children & Schools” and “Indoor Air Quality”classifications. L’Isolante K-FLEX is certified by a similar EU-based organization for producingproducts that are completely harmless with regard to the emission of air-born substances. Thefiber-free formulation of elastomeric insulation eliminates the release of harmful particles intothe air, making it an ideal product for use in public buildings, schools, hospitals, and clean roomapplications where minimum dust and the absence of pollutants are a necessity for efficientproduction processes.PAGE 16

FLAMMABILITYAll K-FLEX USA products are tested for flame spread and smoke development according to ASTME84 test method, “Surface Burning Characteristics of Building Materials”. Reference specificproduct pages for compliance with the 25/50-rating.FLEXIBILITY AND EASE OF USEThe ease of installation of our materials sets them apart from other products on the market.Due to its flexibility, K-FLEX elastomeric insulation is ideal for a variety of applications,including air conditioning ducts, pipes, elbows, valves, and flanges. Professionals will alsoappreciate its cleanliness as it does not leave traces and residues during installation. Restorationand maintenance work can also be completed with ease, resulting in installationtime and cost savings that is unique compared to other materials.QUALITY & SAFETYOur materials are well-suited for applications in environments where strict testing and internationalapprovals are necessary. This includes general construction, marine, mass transit,oil, pharmaceutical and clean-room applications, among others.TEMPERATURE RANGEOur materials are well-suited for applications across a wide range of temperatures.Reference individual product pages for specific temperature ranges.THERMAL CONDUCTIVITY (k FACTOR)Thermal conductivity is a measurement of the ability of a material to transmit heat,specifically the measure of heat in Btus that pass through one square foot of ahomogenous substance, 1 inch thick, in 1 hour, for each degree Farenheit temperaturedifference. The lower the k-value, the higher the insulating value. Most insulation productshave a k-value in the range of 0.23 – 0.30 and would all be considered excellentinsulators.PAGE 17

K-FONIK SOUND INSULATIONinsulation for OPTIMUM LISTENINGENVIRONMENTSK-FONIK acoustic insulation productsare designed to control airborne andstructure-borne noise from mechanicalsystems, air ducts, HVAC rooftop systems,appliances, machinery, transportationvehicles, floors, ceilings and walls, amongothers.Available as high mass noise barriers (GK,GV) and sound absorbers (AB 10, AB 15),K-FONIK products address unwantednoise at its source, path and receiver.With sound quality playing a key role increating environments that promote ahigh level of performance and comfort,K-FONIK products deliver a long-lastingsolution for noise reduction and isolation.K-FONIK AB (10, 15).K-FONIK GK.K-FONIK GV.sound transmission class (STC)Sound Transmission Class is a measureof how well a material or an assemblycan block sound. Specifically, STC iscalculated from sound attenuation (SoundTransmission Loss) values tested at 18standard frequencies from 100 Hz to5000 Hz. These values are plotted as acurve on a sound pressure level graphand are compared to a standard referencecontour. Acoustical engineers fit the valuesto the appropriate Transmission Loss curveto determine an STC rating. STC is roughlynoise reduction measured in decibels thata material can provide.PAGE 92
