Phenolic Window Sills (or Stools) | Lab Grade

Our phenolic window sills, fabricated and supplied by Total Laboratory Solutions and manufactured by the 130-year-old company Fundermax, offer unmatched durability and chemical resistance. Unlike traditional materials, these solid Compressed Phenolic Compact Resin (SPC) panels contain no wood core, require no edge banding, and will not expand, contract, or delaminate. The edges can be profiled, milled, and polished with a standard 1/8" (3mm) bevel and eased corners, making them ideal for high-performance laboratory environments. Architects typically specify thicknesses of 1" (25mm) or 3/4" (19mm) for long-lasting, low-maintenance installations.

Available in industry-standard colors such as black, volcano gray, pastel gray, and white-with smooth texture and black-edge core-these phenolic resin window sills can complement or contrast with laboratory countertops. Additional custom colors are available by special order with extended factory lead times. Multiple profile options allow for wrapping interior and exterior window frames, creating flush or overhanging sills with rabbet ears or rectangular profiles. Optional aprons from 2" to 5" (50 - 125mm) can be added in the field to cover wall imperfections in drywall, cinder block, or composite surfaces.

Meeting the needs of schools, hospitals, research facilities, and water treatment plants, our LEED-certified, low-VOC solid phenolic window stools and aprons provide superior chemical resistance, lighter weight than epoxy, and ease of installation. They are cost-effective, available in longer lengths, and compatible with common lab countertop materials. As the demand for safe, cleanable, and durable laboratory surfaces grows, phenolic solid-surfacing materials have become the preferred choice for modern lab environments.
