Multiwall Polycarbonate 3
Daylighting and Energy Efficiency through “Sustainable “Polycarbonate Solutions
Learning Objectives1. What is polycarbonate and how is it produced2. Characteristics and performance3. Daylighting and sustainability4. Polycarbonate glazing Systems
Multiwall Polycarbonate 4
Polycarbonate Manufacturing
What is Polycarbonate• Polycarbonate is a thermoplastic polymer – 100% Recyclable• Very strong, 200 times stronger than glass• Multiwall is extruded into light weight panels• High light transmittance and low U-Values
Multiwall Polycarbonate 5
Polycarbonate Manufacturing
Extrusion Technology• Screw drives push material through
metal dies• Hoppers at start of machine combine
polycarbonate, additives and recycledmaterial
• Polycarbonate is melted by heatersand friction of system
• Different dies produce differentproduct profiles
Multiwall Polycarbonate 6
Polycarbonate Manufacturing
Co-Extrusion Process
Main extruderPC resin
Co-extruder PC + Uv absorber
• Co-Extrusion process adds a similarmaterial to polycarbonate before passingthrough the die
• Co-Extrusions can provide UVprotection, different colors and Infraredreduction.
• Coatings are added after the extrusionprocess and can include UV protectorsand other performance enhancingadditives.

Polycarbonate Sheeting Materials
Extrusion produces solid and multiwall sheet products
Multiwall Polycarbonate 8
Characteristics andPerformance
• Widths – 4’ to 6’, can be cut to order• Lengths – 24’ to 48’, limited by shipping• Profiles – twin, triple, five …….• Visual and thermal performance• Fire ratings• Loading and application guidelines• Warranties• Specialty features

Polycarbonate Sheeting Materials
Flame Retardant
• Class A: ASTM E 84 Flame spread and smoke density development forinterior surface material: Class A, Flame spread 25 or less and smokeDensity developed rating of 450 or less
• Class CC1: ASTM D635 Burn extent for plastic materials: Class CC1, Burnextent of 1” or less
• Class A and CC1 can be achieved with wide variety of sizes and profiles.

Impact Resistance
• Hail Resistant: Can withstand a .79” Ball impact at greater than 69 ft/s(terminal velocity of hail)
• Many products are Miami-Dade County accepted and ICC ES 3286 compliant

Weather ResistanceWarranty Issues
• Protection from co-extrusion orcoatings
• Can be applied to one or both sides• Standard test ASTM D1003• Verified through weathering
acceleration test and long termcase studies

Polycarbonate Sheeting Materials
Aerogel
• Invented in 1931, not until late 1990’s was it safely produced on a large scale.• Aerogel holds Guinness Book of World Records for the lightest, most insulating
material known.• 97 percent AIR – just 3 percent silica solids.

Daylighting and Sustainability
Improved ProductivityAccording to studies done by the HeschongMahone Group from California, diffuseddaylighting increased retail sales up to 40%for one major retailer. For another,daylighting achieved profits 19 times morethan energy savings.

Daylighting and Sustainability
Reduced Energy Consumption• Rule of thumb: Each kWh of electricity usedfor commercial lighting adds .5 kWh ofelectricity needed for cooling - daylightingsaves both lighting and cooling loads
