Compact laminate refers to a type of high-pressure laminate (HPL) that exceeds 2mm in thickness. Compact laminates are more resistant to impact, abrasion, moisture, scratch, chemicals, and heat than thinner HPLs. They are often used as partitions, wall cladding, commercial countertops, casework, and furniture in heavily trafficked public areas, especially where hygiene is a priority. Compact laminates come in a wide variety of designs and thicknesses, and unlike thinner HPLs, some are sturdy enough to support themselves under certain conditions.
