Nitterhouse hollowcore is a precision-manufactured, precast/prestressed concrete plank produced with normal-weight, high-strength (5,000 psi minimum) concrete. Hollowcore floors and ceilings offer superior durability and natural sound attenuation.

As a decking material, hollowcore provides a completely finished ceiling surface that can be used as installed or can be painted or sprayed with an acoustical (or textured) spray. For ceilings that require the installation of dropped ceilings and special lighting, hollowcore can be drilled or shot to install electrical, as well as HVAC fixtures.

With its strong, durable, uniform deck, the hollowcore surface merely needs minimal cast-in-place concrete topping or leveling coat for smooth floor finishes when applying tile, marble, or linoleum. For carpeting, even less surface preparation is required, depending upon camber. Typically, all that is required is feathering the joints with a latex cement or grout. The surface is then ready for application of a separate, 55-oz. pad and carpet for a completely finished floor.

Benefits of Hollowcore:

• Fire-Resistance Ratings of 1.0 Hour and 2.0 Hours are available
• Precision cast using 5,000 psi (minimum) concrete
• Low maintenance
• Fast, all-weather construction
• Superior loading
• Strong, durable, and clean
