Today, with fifty years of experience in the industry, Sheffield has grown to becomea recognized leader in high performance plastics, supplyingmaterials for architectural, industrial, commercial, and aerospace with its European affiliate, Sheffield Plastics is a global leader in producing polycarbonate sheet in theworld.

2 Wherever high performance glazing materials arerequired, Sheffield has the technology to fit the TougherSheffield Plastics polycarbonate sheet is produced underrigid quality control specifications, meeting ISO certificationguidelines for both plants and processes. Polycarbonate resins supplied by Bayer, combined with the latest in production technology, assure that the physical properties of MAKROLON polycarbonatesheet will meet or exceed the performance characteristics of any directly competitive product on the market HYGARD Laminated Sheet .. 10-11 Technical DataPhysical Properties, Code Ratings .. 12-13 Warranties.. 13 InstallationGuidelines and Procedures .. 14-15 SpecificationsGeneral Product .. 16-17 IntroductionContents2 MAKROLON Polycarbonate Sheet is Clearly the Right ChoiceCost EfficiencyThe unique combination of lightweight (half the weight of glass) and high strength inherent in MAKROLON polycarbonate sheet allows designs that require lessstructural support.

3 Since MAKROLON polycarbonatesheet can be cut and cold-formed on-site, you save time and money that would normally be dedicated to preinstallation techniques like oven polycarbonate sheet is much more durablethan other material options. The cost of replacementbecomes a less immediate (and less costly) EfficiencyMAKROLON polycarbonate sheet is a superior insulatingmaterial when compared to equivalent thicknesses of glass. Double-glazing and overglazing offer even moreenergy savings. Overglazing with a patterned grade ofMAKROLON polycarbonate sheet adds visual security and enhances the appearance of industrial and commercial and Energy TransmissionBy allowing the transmitance of up to 90 percent of solarenergy and 88 percent of visible light, clear MAKROLON polycarbonate sheet is an excellent glazing material for a wide range of applications where clarity is polycarbonate sheet is also available in grayand bronze tints to help control heat gain, and provide avariety of privacy patterns for obscure glazing can you tell if polycarbonate is the right choice foryou?

4 It s simple! Only polycarbonate can offer the idealcombination of impact strength, cost effectiveness, andenergy efficiency. No glazing alternative can surpassMAKROLON polycarbonate sheet for superior all-aroundperformance. It s the right choice for almost anydemanding glazing polycarbonate sheet is as clear as glassand hundreds of times stronger. It s also many timesstronger than acrylic sheet offering a margin of safetythat no other clear glazing material can beat. With itsinherent design flexibility, MAKROLON polycarbonatesheet can be cut or cold-formed on-site during installation,without the preforming and fabrication associated withglass or acrylic. It is lightweight and requires lessstructural support than all-glass systems, savingadditional time and labor costs.

5 Its durability and energyefficiency add up to long term cost savings. Fromskylights and barrel vaultsto educational and institutionalglazing, the question is not why, but where polycarbonate?Built to Perform Transportation Glazing Institutional Glazing Barrel Vaults Skylights Covered Walkways Storefronts Privacy Glazing Factory OverglazingDon t let material limitations compromise your designcreativity. MAKROLON polycarbonate sheet is designedto perform in a wide range of applications and meets allstandard architectural specifications and ProtectionUnsurpassed by any clear glazing product on themarket, MAKROLON polycarbonate sheet is hundreds oftimes stronger than plate glass and many times strongerthan acrylic. This tough, long lasting material offersattractive protection in areas subject to high traffic,vandalism or burglary.

6 It even withstands natural forceslike severe wind, hail, and snow storms. In fact,MAKROLON polycarbonate sheet meets stringent statemandates for hurricane resistant glazing LatitudeMAKROLON polycarbonate sheet is extremely can be cut on-site from flat sheet or cold-formed into curves that would be impossible to construct withlaminated glass or acrylic.

7 Now think of the demanding applicationswhere glass and acrylic have been tried and failed;schools, psychiatric facilities, subways, bus shelters,etc. These sites are increasing because of violenceand vandalism. Add applications where other plasticsdidn t rise to the challenge and your list of failuresgrows long. Now try MAKROLON polycarbonate sheetand turn failed designs into family of MAKROLON polycarbonate sheet glazing products offers superior durability, unmatched design flexibility, and structural integrity that easily surpasses laminated glass and acrylic alternatives. Whenconsidering total life cycle costs, MAKROLON polycarbonate sheet comes in several grades to suityour every performance requirement: MAKROLON GPpolycarbonate sheet for general glazing and industrialapplications; MAKROLON SL polycarbonate sheet for increased UV protection; MAKROLON AR polycarbonate sheet when abrasion resistance, impactstrength, and graffiti removal are essential.

Available in clear, colors and privacy patterns, MAKROLON GP polycarbonate sheetis a high performance, all purpose glazing material thatis both durable and cost effective. This performance isbacked by a comprehensive warranty against polycarbonate sheet is available in a wide variety of thicknesses,colors, sizes, and SLFor the most demandingoutdoor environments6 MAKROLON SLSunLifePolycarbonate Sheet Prolonged exposure to the sun can weather even the most durable of surfaces. In the past, acrylic was often chosen for plastic glazing applications because of its inherent resistance to yellowing over time.

10 But compared to polycarbonate, the relative brittleness of acrylic madeits impact strength insufficient for demanding, vandalresistant applications. To meet this need, SheffieldPlastics developed MAKROLON SL polycarbonate offers the best of both worlds the impact protection ofMAKROLON polycarbonate sheet and the UV resistanceof acrylic. Utilizing advanced formulations combined withstate-of-the-art extrusion technology, Sheffield Plasticshas created a tough, consistent quality product that willexhibit superior performance for years to WarrantyThe performance of MAKROLON SL polycarbonate sheet has been well documented through years of laboratory and field testing.
