From walls to rooftops — Karp's comprehensive product range covers every access point in commercial and residential construction.
Karp believes we all share the responsibility for our environment. Our shipping cartons are made of recycled corrugate, catalogs and unused printed material are donated yearly to a community recycling facility, and Karp's new paint system is approved by the EPA.
Karp's customized electrostatic powder paint system provides customers with a high quality, durable finish, with a much higher resistance to corrosion. Karp's powder contains no damaging solvents and therefore no toxic fumes are emitted into the atmosphere.
Trusted by contractors, architects and builders across the United States.
