Common Product: Medium Density Fiberboard (MDF)

Medium Density Fiberboard (MDF) is a non-structural wood panel product constructed using wood residues from the production of primary wood products. MDF is produced by blending these wood residues with resin(s), resin catalyst, and wax, followed by curing under pressure and heat. Urea-formaldehyde (UF) is the most commonly used resin for MDF, however other resins such as melamine-urea formaldehyde or polymeric isocyanate resins may be used when moisture resistance is specified or a no added formaldehyde (NAF) resin is desired. This CP models a standard MDF product made with UF resin.

Common Product: Plywood

Plywood is constructed using thin layers of wood, called plies, bound by resin. A variety of wood species may be used depending upon the application. This CP is for flooring underlayment and roof and wall sheathing applications, which often use softwood species such as Yellow Pine or Douglas Fir. Plywood underlayment and sheathing is commonly constructed with a moisture resistant resin, such as phenol formaldehyde, and is typically sold in 4 x 8 ft planks of 9 mm to 18 mm thickness.

Common Product: Steel Door

This CP reviews a standard duty, flush, hollow steel door intended for interior uses where insulation is not a concern. The Steel Door Institute considers this a Level 1, Model 1 door, which is not fire-rated, but is suggested for use in a variety of situations in commercial spaces. The core is honeycomb, a matrix of resin-impregnated kraft paper, which provides structure and acoustical performance. The core is attached to the door skins with a rubberized contact adhesive before channels are spot welded to the top, bottom, and sides to completely encase the core. This CP describes a door that is factory-primed and painted on site. Knobs, hinges and other hardware required to make the door operational are not included in this CP.
