LG Hausys America, Inc. offers three categories of high-quality surfacing materials for commercial and residential use.

The Solid Surface category offers several product lines in a wide variety of colors and patterns. These include HI-MACS, Volcanics, Lucent, and Spectrum. All of these solid surface choices are durable, hygienic, and stain-resistant, making them ideal for nearly any application, including residential kitchens, bathroom vanities, and a variety of commercial interior spaces including healthcare, hospitality and education.

The LG Hausys America, Inc. Stone category includes Viatera quartz surfacing. Made from natural stone and advanced polymer resins, Viatera provides consistent color choices and hygienic properties with the look and feel of natural granite.

With the LG Hausys America, Inc. Eco category, designers and consumers can choose more earth-friendly products. This category includes Eden Solid Surfaces, one of the most environmentally conscious acrylic products available. Eden has a minimum of 12 percent recycled content and help specifiers earn credits toward LEED certification in several categories.

These three product categories are supported by a collection of accessories, including stainless steel sinks, solid surface sinks, adhesives, and stainless steel grates.

Earth-Friendly: In 2008, LG Hausys America, Inc. received the Envision Award from the International Solid Surface Fabricators Association (ISSFA) for Eco Eden Solid Surfaces. Certified by Scientific Certification Systems (SCS), Eco Eden Solid Surfaces helps customers meet the demands of green building standards and programs through earning points toward LEED certification within the Materials and Resources category. It is manufactured using a minimum of 12 percent pre-consumer recycled material (resin), so it is not only durable and versatile, but also an environmentally-friendly surface for any application.

All LG Hausys America, Inc. products are GREENGUARD Indoor Air Quality Certified. LG Hausys America, Inc.'s products have been tested and evaluated by a GREENGUARD Environmental Institute (GEI) approved laboratory and determined to meet GREENGUARD Emission Standards. GREENGUARD is the only industry independent certification program for low-emitting products. Products displaying the GREENGUARD mark are subject to ongoing testing to maintain certification.
