UPM ProFi Piazza Technical Specification MATERIAL PROFILE SURFACE PHYSICAL AND MECHANICAL UPM ProFi Piazza is an environmentally innovative composite material made in Germany that combines the best qualities of plastic and engineered fibers which fall as surplus by-products in self-adhesive label manufacture and processing. UPM ProFi Piazza is lignin free and therefore offers better colour durability than traditional WPC. The material contains no harmful chemicals. Compared to traditional WPC boards, the closed surface is also more resistant to oil spills and stains. Solid profile made by extrusion technology High performance polymer cap surface with a natural looking hardwood embossing. Property Test method Linear Mass Bending Strength, N/mm² Thermal Expansion Coefficient, 1/°C Fire Class Slip resistance Flexural modulus, N/mm² *Based on CEN/TS 15534 wood plastic composites (WPC). The values above are characteristic values from quality tests and therefore not for strength calculations in the serviceability state. 25 mm x 140 mm; length 4 m & 5 m UPM ProFi Piazza will expand and contract with changes in temperature.

THERMAL EXPANSION UPM ProFi Piazza will expand and contract with changes in temperature. The following table shows this effect over different temperature changes. The temperature change listed relates to the temperature of Piazza material, not the air temperature. Numeric example of the thermal length expansion according to length of UPM ProFi Piazza decking board: Temperature change of board (∆T) 10°C Based on an expansion coefficient of 4 x 10 -5 1/°C. At a temperature of material about 20 °C during installation or cutting, in summer a 4 m board will expand around 6 mm as the board warms...
