THICKNESS - In addition to the wide variety of sizes available, DURATOP solid cast epoxy lab work surfaces, with their smooth, non-glare matte finish, are molded in several thickness'. When fabricating Duratop laboratory tops and sheet material at the ISO 9001 certified manufacturing facility, all fabricated cuts are made with diamond tipped, water cooled, rotary saws and sink cutouts, faucet or gas tap holes or other service hole requirements, are cut with CNC diamond tipped routers and drill bits. Typical specification for epoxy countertops in accordance with The Woodworking Institute (W.I.) and its affiliates is 25 mm or 1" Thickness. The maximum span for unsupported epoxy shall not exceeed 48" (1219 mm) without intermediate support. The maximum cantilever shall not exceed 12" (305 mm) without intermediate support.

EPOXY CURBING 100 mm (4") typical, also known as applied splash, is supplied loose with each sheet order if required ,
cut to size to match the countertop sizing, or can be field cut from sheet material to meet job requirements. Top front edge is typically eased with a 3/16" Radius, Bevel or chamfer. Epoxy sinks, drain outlets, Pegboards & Stainless Steel Troughs, faucets, eye wash, drench showers, etc., are offered to complete the lab requirement. A drip Groove is typically cut on the underside of the sheet material at a prescribed depth and distance from the edge.


COVED CURB back splash is also offered in 4" molded one piece height. Coved Curb worksurfaces should be used when reducing the number of back splash joints is of high priority or architectural specifications call for integral coved curb splash. They are available in seamless lengths up to 96" [2438mm] and depths up to 38" [965mm]. Other sizes are available.




Coved Curb worksurfaces are integrally molded 1" [25mm] thick with cove tapered at the top to 3/4" (19 MM). By special request, 3/4" or 1-1/4" [19mm or 32mm] thick worksurfaces can be ordered with an Integral curb of 4" [102mm] tall. For other special height integral curbs, please contact ISI for availability.
Both Left and Right side Corner Curbs are also available at a size of 44" finished inches (1118 MM). This corner coved curb comes with a 44" Side Curb (1118 mm) and a integrally molded back splash curb of 44" (1118mm). The depth of 44" can then be fabricated and reduced to the required width or depth of the counter required, be it 25", 30, 31", etc.
Unapplied Marine Edge (UME) Duratop epoxy UME strips are used for attachment on the top surface of counter top material to form a marine edge and offered in 1/4" (6mm) thickness and 8' (2.438 meters) long. Color matching epoxy adhesive is available. Marine edges are also integrally molded on certain sized sheet materials.
