PANEL M EDIUM DENSITY FIBERBOARD M edium Density Fiberboard (MDF) is widely used in the manufacture of furniture, kitchen cabinets, door parts, mouldings, millwork and laminate flooring. MDF panels are manufactured with a variety of physical properties and dimensions, providing the opportunity to design the end product with the specificMD F needed. MDF is a composite panel product typically consisting of cellulosic fibers combined with a ➊ synthetic resin or other suitable bonding system, joined together under heat and pressure. Additives may be introduced during manufacturing to impart additional characteristics. The surface of MDF is flat, smooth, uniform, dense, and free of knots and grain patterns. The homogeneous density profile of MDF allows intricate ➎ and precise machining and finishing techniques for superior finished products. Trim waste is ➏ significantly reduced when using MDF compared to other substrates. Stability and strength are important assets of MDF, which can be machined ➋ into complex patterns that require precise tolerances. ➌ ➍ 10 subscribe online at www.surfaceandpanel.com M EDIUM DENSITY FIBERBOARD COMMON USES D OORS, JAMBS & MILLWORK LAMINATING & FINISHING EDGE ShAPING & MACHINING MOULDING EMBOSSING OFFICE & RESIDENTIAL FURNITURE KITCHEN CABINETS PANELING LAMINATE FLOORING ➐ STORE FIXTURES ➑ ENGINEERED FOR THE FUTURE • 100% POST-INDUSTRIAL RECYCLED FIBRE Sustainable Forestry Initiative® 1ST NORTH (SFI)Certified AMERICAN • 100% NO ADDED FORMALDEHYDE (NAF) MDF MILL TO BE 100% NAF • ALL PRODUCTS ARE CARB EXEMPT Post-Industrial Recycled Wood Fiber West Fraser is committed to producing MDF panels MDF IS THE PERFECT SOLID WOOD and programs designed to meet the changing needs SUBSTITUTE.

CUSTOM CLOSETS, CABINETS AND BUILT-INS (ANSI A208.2) is the North American industry voluntary standard. SHOWCASE THE PERFORMANCE BEAUTIFULLY ➋. It classifies MDF by physical and mechanical properties and identi- fies product grades. Specifications identified in the Standard include physical and mechanical properties, dimensional tolerances and formaldehyde emission limits. The Standard was developed through the sponsorship of the Composite Panel Association, in conjunction with producers, users and general interest groups. A summary of the ANSI Property Requirements are included in this Guide, and copies of the Standard are available from CPA. Third-party certification to ANSI A208.2 is required for many The new generation: applications of composite panels. For example, HUD and the High-Performance HydroWax® Dispersions states of California and Minnesota require third-party certification of formaldehyde emissions for nearly all MDF and particleboard under their jurisdiction. Environmental Product Declarations (EPD) are the widely accepted standardized specification format for communicating the environmental footprint and performance of a product. EPDs are the definitive source of environmental technical data that is scientifically based on life cycle analysis and can be used to directly compare alternative product materials. An EPD for North American MDF is now available. See page 8 of this Guide for additional information. MD F CONTINUED ON PAGE 14 � ➋ www.sasolwax.com HydroWax® means more than just wax-in-water.
