About Our Various Laminate Types.
Three “grades” of High Pressure Decorative Laminate (HPDL) comprise the Wilsonart “Basic Types” category: Type 107 and 350 are both Horizontal Grade Laminates; Type 335 is recommended as a Vertical Grade. Performance characteristics differ very little between these three types/grades. For example, wear resistance is the same for any specific design/finish combination because the decorative sheet/finish configuration is the same on each of the three basic grades. Other surface performance characteristics, like stain-resistance, fade (light) resistance, scratch resistance, and appearance properties are also the same for this reason. The three types are primarily differentiated by the thickness and type of phenolic/kraft core incorporated into the sheet. This core consists of multiple layers of kraft paper saturated with phenolic resin for strength. The number/type of kraft layers contribute to the thickness, impact resistance, and postformability of the laminate.
Horizontal grade laminates are generally thicker than 0.028” (reference AWI— Architectural Woodwork Standards—Section 4— Sheet Products, 4.2c.4.1). Wilsonart Type 107 (HGS—Horizontal Grade Standard) and Type 350 (HGP—Horizontal Grade Postforming) are included in this category. These thicker composites offer suitable impact resistance for the rigors and abuse that horizontal work surfaces experience. While both products are designed for similar applications, Type 350 can be also postformed or bent with heat to create a profiled edge.
Vertical grade laminates are 0.020” -0.028” (AWI— Architectural Woodwork Standards—Section 4— Sheet Products, 188.8.131.52). Wilsonart Type 335 (VGP—Vertical Grade Postforming) fits into this category. These thinner composites offer suitable impact resistance for vertical applications that will experience limited impact yet still require good surface durability. This product type can also be postformed. While VGP products are intended for vertical applications, they are often used for some horizontal applications where limited impact is anticipated, including office furniture and retail displays (among others).
