EPiC database - Plywood CrawfordRobert StephanAndré PrideauxFabian 2019 This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.<br><br>Plywood is a manufactured timber product made from thin veneers of timber bonded together under heat and pressure. Typically the outer layers (face timbers) are a higher grade with superior aesthetic qualities. Plywood is a high-strength, high quality sheet material, with good dimensional stability and resistance to cracking and warping. <br><br>Veneers are ‘peeled’ off a timber log to a precise thickness, and laminated together with other veneers, typically at different orientations to provide increased strength and stability. They are bonded with urea formaldehyde or a water-resistant glue such as phenol formaldehyde. <br><br>Plywood is available in a variety of grades, and timber species. These include high grade interior plywood, formply, exterior/marine grade plywood, and structural plywood.
